tional Museum. He pointed out the distinct characters of the 
two insects and saw the close resemblances of the galls. The 
insect of compta is abundantly distinct from all the other 
varieties of this species except anceps. The ranges of compta 
and anceps overlap at Austin, and 7 of the 60 insects I have 
from Austin appear intermediate between the two varieties. 
There is no apparent reason why they should not interbreed 
in that region, but material from more eastern Texas is en- 
tirely anceps. As soon as the geographic isolation is sufficient, 
the two insects maintain themselves as distinct.

FEMALE. — In color reddish rufous and black; antennae dark 
brown, the first two segments light rufous; mesonotum moderately, shal- 
lowly punctate and moderately hairy, very finely coriaceous posteriorly, 
irregularly roughened elsewhere between the punctation; anterior par- 
allel and lateral lines rather broad, for the most part punctate or 
roughened; median groove almost absent; scutellum a little longer than 
broad, coarsely rugose, its median ridge more or less evident; foveal 
groove broad, more or less smooth at bottom; abdomen dark rufous to 
piceous, hardly elongate, the second segment somewhat tongue-shaped, 
covering two-thirds of the abdomen; legs dark rufo-brown, light rufous 
at some of the joints and on the trochanters; wings long, about 1.30 
times the body length; the areolet of moderate size to small; cloud on 
the first abscissa of the radius of moderate size, smaller than in compta; 
tip of the radius hardly at all enlarged; body generally smaller and 
more slender than compta , 3.0 to 4.0 mm., averaging about 3.5 mm. in 
length. Figures 337, 389. 
GALL. — Pubescent when young, finally naked, whitish to flesh- 
colored; rounded or flattened at base; occurring singly on the leaves of 
Quercus alba, Q. stellata, Q. floridana (and Q. Margaretta?) , Q. Chap - 
manni, and Q. breviloba.
