Andricus infuscatus, n. sp. 

Quercus catesbaei [laevis]

Gall.--A globular, fleshy gall, densely covered with yellow wool; diameter .23 to .25 inch. It is attached by a slight point to the upper surface of the leaf and when mature is in reality nothing but a hard, tough, larval cell, covered with wool; the wooly covering is easily detached. It is monothalamous; occasionally several galls occur together on the leaf compressing one another into odd shapes but the galls fall to the ground, separate and renew their globular form, and the fly reaches maturity in the damp earth. 

Described from several specimens reared in March.

Neuroterus laurifoliae, n. sp.
The Laurel-oak wooly gall

Galls on the Laurel Oak (Quercus laurifolia)

Gall. An oblong, wooly gall on the upper or lower surface of the leaves; the wool is fawn colored, long and fine, covering three or four, sometimes more irregularly rounded, flattened disks, in the centre of which live the flies; they are attached to the midrib by a nipple-like point; the disk or cell is concave above and measures .08 to .10 inch in diameter. 

Several specimens bred. The fly very strikingly resembles Neuroterus verrucarum, but the gall is very distinct and cannot be confounded with it.

Acraspis vaccinii n. sp.

On the Post Oak (Quercus obtusiloba [stellata])

Galls. — "Clusters of small, somewhat bell-shaped, petiolate, greenish galls on the under side of the leaves, along the midrib. Their shape may be compared to that of the flowers of vaccinium. They are attenuated at the basis into a short petiole, fastened to the midrib of the leaf; the opposite end is truncated the truncature being excavated; the length, from the foot of the petiole to the truncated end, is from 0.12 to 0.15 inch. They grow in numbers, sometimes of ten or more together, so that six, for instance, form a row on one side of the midrib and four or fi\e on the opposite." — Osten Sacken. 

Described from two specimens bred in February, 1886. 

This gall is common; begins developing in August, but does not reach maturity until last of December. I have found the same gall on the Post Oak at Asheville, N. C. Baron Osten Sacken mentions having found this species in his second paper on North American Oak Galls 1862, p. 255, from whom the description of the gall is taken; he did not, however, breed the fly. 

Andricus femoratus n. sp.

A small, very thin shelled globular gall, containing a larval cell held in place by fine radiating filaments; diameter 0.3 inch. Described from one specimen reared May, 1886 [On Quercus laurifolia]

Andricus stropus n. sp. 

The Leafy-wreath Gall

Galls.--A diminutive, brown, acorn-shaped gall, issuing from a bud axil, surrounded at base with small, narrow, dense leaflets. The gall, itself, when removed from its leafy matrix is oblong-oval; in height .15 inch; diameter through .1 inch, and has a little nipple on top. It, too, drops to the ground, but unlike the other species just described, there is but one cell to each gall. 

Amphibolips spinosa n. sp.

Galls on the Laurel Oak (Quercus laurifolia)

Gall.— A small, brown globular gall, covered with prickles or spines; the shell is thick and covers with a slight spongy substance, a thin larval cell; diameter .30 inch. 

Described from one specimen reared in January. 

The Woolly Gall of the Water Oak. Cynips q. turnerii n. sp. 

Galls. — Globular, woolly galls, the size of an oxheart cherry, attached to the aments of Quercus aquatica [nigra]. Externally covered with dense, fine, rather long wool, white at first, but becoming rusty with age; internally consisting of numerous, triangular seed-like kernels, each kernel containing two cells. Length of kernel .12 inch. Diameter of gall one-half inch. 

Described from three bred specimens which issued from galls April 28th. This interesting gall, I take pleasure in naming after my friend Dr. R. S. Turner of Fort George, Florida, who was the first to bring me specimens. I have, however, since found it quite abundant on several trees in Jacksonville.

Dryophanta carolina n. sp.

galls on White Oak (Quercus alba)

Gall. — A small, hard cellular, finely pubescent globular gall, .20 inch in diameter, slightly attached to the petiole of a leaf. 

Described from two specimens reared in February from galls collected in Asheville, K. C, October, 1886. 

Dryophanta cinereae n. sp.

Quercus cinerea [incana]

(The Upland-willow Oak Spangle Gall.) 

Galls. — Small, semispherical galls, sessile on the under surface of the leaves; internally there is a loose kernel which moves freely about. 

While the fly of this species might easily be confounded with those of the others, the gall easily separates it; it does not project above the upper surface of the leaf as do the other species. Very rare. 

Neuroterus longipennis n. sp.

Quercus laurifolia

Swellings surrounding the base of new shoots or twigs; hard, woody, structure. Small size. 

 Galls. — Small, oblong, irregular, woody swellings, surrounding the base of new shoots, from .35 to .40 of an inch in length, by from .14 to .16 inch in diameter. 

Described from eight specimens bred May, 1886. 


Eumayria floridana n. sp.

[Described from adult only, captured in March]


Biorhiza mellea n. sp.

Quercus obtusiloba [stellata]

Galls — Small, brownish yellow, globular galls, occurring separately or in clusters of three or more together, on the upper surface of the leaf, attached by a slender point and easily detached. Externally they are covered with minute warty, pubescent dots; internally they are fleshy, but when fully matured are of a more or less cellular consistency and shrivel in drying. Diameter .10 to .15 inch. They fall to the ground and mature in the sand and fallen debris. 

Described from eight specimens reared in February. Occurs on Q. parvifolia [chapmanii?]

Acraspis lanaeglobuli n. sp.

Host: Quercus bicolor [michauxii?]

Gall - Round or globular galls, slightly attached to the under surface of the leaf: .30 to .35 of an inch in diameter and covered with a fine, dense, grayish pubescence; internally, of a pithy structure, with a large, thin-shelled kernel in the centre. 

Described from 8 female bred specimens.

Callirhytis seminator

This species, before only recorded as occurring on the white oak (Quercus alba), is not unconnnon here, both on Quercus prinus and on the swamp white oak Quercus bicolor. Callirhytis operator O. S., occurring on the black-jack ( Q. nigra) may be a phytophagic variety of this well known specie ; the galls are similar, but the flies are certainly distinct. I have both species in my collection. Calllrhytis seminator begins to develop here, on the small twigs, in April ; by the middle of June the flies are fully developed, but they do not escape from the galls until the first week in July. 

Callirhytis clavula

Terminal or subterminal swellings of the limb
Monothalamous; of a hard, woody structure

Syn C arbos, C tuber (Q alba); Neuroterus phellos (Q phellos); C similis (Q ilicifolia); C aquaticae (Q aquatica [nigra])

Andricus (Trisolenia n. g.) saltatus n. sp. 
The Blue Jack Jumping Gall

 Galls. — Oblong-oval, longitudinally ribbed, brown galls, without a distinct cell, occurring two or three together and issuing from the bud axils in early spring; they are but slightly attached and fall to the ground on the slightest jarring of the tree.

This gall was discovered three years ago; it appears the last of March, and when first taken from the tree and for several weeks afterwards, has the power of jumping, due to the contractions and sudden relaxation of the larva within; some of them will jump three-quarters of an inch off the table. Out of nearly two hundred galls gathered the first year of its discovery, but one reached maturity; all the rest died. This specimen was just eleven months and some days in the gall. In 188.5 but three specimens were raised, one a male, and the period of development was the same. This year all my specimens seem to be dead, although I collected at different times and endeavored as far as possible to collect the most matured specimens; evidently the season was too dry for them. Last March I collected two females while ovipositing in the buds; the ovipositor was so deeply immersed in the bud as to enable me to capture the flies in my fingers before they had time to withdraw and escape; they agreed perfectly with the bred specimens. 

Callirhytis parvifoliae n. sp.
Gall--A small rounded gall on the midvein of a leaf, half projecting above and half below the surface of the leaf, and usually but not always, the portion above the upper surface, is deeply indented. It is polythalamous and contains several larval cells all radiating from the centre. Diameter .12 to .15 inch.

This gall is not rare on Q. parvifolia [Quercus chapmanii].

Andricus blastophagus n. sp.

Galls. — Minute, smooth, oval galls the size of an entomological pin-head, occurring on the aments or blossoms ; they are so small as to be easily mistaken for the ovaries.

This interesting little insect is described from several specimens bred in May, 1886.

Andricus cinnamomeus n. sp.

Gall — A small, cone-shaped bud gall measuring 0.35 to 0.40 inch in length by 0.15 to 0.17 inch in diameter, covered with short deformed leaf scales. The egg is evidently deposited in the fall or midsummer, causing an abnormal development of the bud and bud scales, which cover the gall. The larval cell is thin, whitish in color, cocoon-shaped, and attached to one side at the base of the gall. One might easily cut into and open the gall without finding it, for unless he accidentally cuts into the side where the cell is situated, it would remain undiscovered.

Described from several specimens bred in April 1887. Occurs on Quercus parvifolia.

[Andricus calycicola n. sp.](https://www.biodiversitylibrary.org/page/7475061)

Gall - A small, smooth, hard, but thin shelled globular form .10 to .15 inch in diameter, issuing from a bud, but occasionally enclosed by the bud scales or by an aborted acorn cup. This gall develops very rapidly in the fall (October) and it drops to the ground where under the fallen debris the final transformations of the single enclosed larva is consummated, gnawing its way out of the gall in February. 

Host - Quercus laurifolia [NOTE: this host record is suspect since it's in a different section than Q. chapmanii. Weld (1922) synonymized A. calycicola with A. cinnamomeus.]

Andricus cryptus n. sp. 

Gall--Small cocoon-like gall one-tenth of an inch in diameter, hidden in a branch under the bark and not visible externally. There is no appreciable swelling of the branch from this gall-fly, the fly escaping by cutting a hole from its larval cell through the bark; observing these holes in the bark led to its discovery.

Described from two specimens reared in May, 1886.
