Dactylosphaera globosum
Gall No. 10.

Hosts: Carya amara [cordiformis]

This is the gall of my B. globosum, described at length in Proc. Acad. Nat. Scr. Phil., Jan. 1867, and, with No. 8, are the only known Hickory galls that have the character of being soft and leathery in structure. The perfect insect was found between Sept. 20th, and Oct. 20th 1866, since which time I have not seen it. I then described it as being found on what I supposed to be Carya glabra, but which now proves to be C. amara. See below.

This is so manifestly distinct from caryae-globuli, Walsh, that a comparison is uncalled for; the latter is said to mature in June, while globosum matures in October; and the opening of the galls are quite different in shape, that of globosum being rounded and on a nipple-like projection, while that of caryae-globuli is an elongated slit.

I am not at all certain that Gall No. 8, is specifically distinct from this.

Dactylosphaera coniferum, n. sp.
Gall No. 11

Hosts: Carya amara [cordiformis]

Very thick, depressed, slightly elevated above the leaf conical below ; contained many larvae and yellow pupa, but at this date (June 18th) too late to find the eggs. This gall is almost like No. 4 with the walls much thicker.
