The species, received through the courtesy of the United States National Museum, was reared April 21, 1885 from leaves of box elder, Negundo aceroides, collected by Theodore Pergande May 12, 1884 in Virginia. Mr Pergande states that the larvae deserted the gall May 15th and entered the ground, remaining there until the following spring. Apparently the same form was received June 20, 1908 from the late Dr James Fletcher, Ottawa, Can., and again July 8, 1916 from Winnipeg, Manitoba, through J. M. Swaine, assistant entomologist of the entomological branch of the Canadian Department of Agriculture. It may possibly be identical with Cecidomyia negundinis Gill.

Gall. Irregular, globose, pocket-shaped, separate or confluent, midrib or vein swellings, usually with a slight enlargement on the lower surface and a marked elevation on the upper surface. The color may vary from a light bluish green to a yellowish or even deep red ; diameter 2 to 4 mm, the opening on the under surface. Badly infested leaves may be crumpled and yellowish.

Andricus montezumus

Irregularly rounded, polythalamous, as it ages becoming brown, rugose, fissured, length 55 mm, diameter 3.5 mm, on live oak. 

Cincticornia quercifolia

A flat, relatively inconspicuous, presumably blister gall on Q rubra

Cincticornia serrata

A broadly yellow-margined, circular, blister leaf gall, diameter 3 mm, on Q coccinea

Cincticornia pustulata

A variable brown, irregularly oval, pustulate leaf swelling, diameter 5 to 6 mm, on Q velutina, Q rubra

Cincticornia simpla

An irregularly oval, pustulate swelling showing equally on both leaf surfaces but with no nipple, diameter 5 to 6 mm, on Q rubra, velutina

Cincticornia sobrina

Irregularly oval, pustulate leaf swelling showing equally on both surfaces but with no nipple, diameter 5 to 6 mm, on Q velutina

Cincticornia americana

A slight, circular, blisterlike swelling of the lateral veins, length 3 mm, diameter 1 mm.

Cecidomyia sp.

Blister leaf gall, inconspicuous, greenish, diameter 4 to 5 mm, on Q agrifolia

Cincticornia podagrae

Narrow, dark purplish, fusiform, thin-walled swelling on the under side of the mid or lateral veins may contain two or more larvae, length 8 mm.

Cecidomyai niveipila

Large, midrib fold with a conspicuous, white pubescence, the leaf frequently deformed

Cecidomyia sp.

Fusiform, thin-walled, striate, pale green vein swelling, length 5 mm, diameter 3 mm, on red oak

Parallelodiplosis florida [an inquiline]

Elongate, pocketlike swellings along the midrib of round-leaved scrub oak, length 5 mm.

Cecidomyia oruca

Elongate fold gall close to the midrib on the under surface, length 12 mm, diameter 1 mm, on Quercus, possibly identical with the preceding.

Itonida foliora

Gall a folded leaf edge between serrations

Cecidomyia erubescens

Galls similar, possibly identical

Cecidomyia sp. [Doesn't appear in main body of text?]

Oak leaves with lobes folded by Cecidomyia sp., adult unknown

Cecidomyia sp.

Fusiform ribbed or carinate mid or lateral vein folds on the under surface, length 6 to 8 mm, diameter 3 to 4 mm.

Andricus howertoni Bass

Irregular, monothalamous, green twig galls, length 18 mm, diameter 12 mm, when green covered with leaves, on Quercus species
