The gall is attached by a single small point to the side of an 

 acorn cup of the black jack oak (Q. marylandica) . It is per- 

 fectly round and smooth and measures from 24 to 42 mm. in 

 diameter. When dry it is brown and rusty brown inside and 

 of a dense corky consistency. Internally it contains a large 

 central larval chamber, which is firmly imbedded in and adher- 

 ent to the surrounding mass. The imago is one of the largest 

 species and is closely allied to A. prumis. The gall is probably 

 red or yellow when fresh. 



Habitat: Texas.

A small red gall measuring from 8 to 12 mm. in diameter. It 

 is rounded or spherical, smooth, and of a corky texture, with a 

 central larval cell. Dr. W. H. Ashmead states that the galls 

 drop from large trees of willow oaks (Q. laurifolia) in August 

 and that he was unable to find out whether they grow on the 

 twigs or leaves. I am of the opinion that it is an acorn gall, 

 growing on the cup, owing to the resemblance of the adult and 

 structure of the gall to that of A. primus. 



Habitat: Florida.

The gall of this interesting species occurs in the meaty part 

 of acorns of scarlet, red and black (Q. tinctoria) oak and prob- 

 ably others belonging to the red oak group. It consists simply 

 of a hard rounded kernel or larval cell imbedded in the inside of 

 the acorn. Sometimes there are more than a dozen larval cells 

 closely pressing upon one another and filling the whole interior 

 of the acorn. The gall matures in the autumn and the adult
