records undoubtedly represent extreme northern localities for 
an insect which centers chiefly in the southeastern quarter of 
the country just north of the Gulf Coast. 
Our Georgia material emerged on November 19 and Decem- 
ber 6 (1928). The Riley County material is recorded as 
emergent in January (with one specimen labelled November) . 
The insects of cruenta are perfectly distinct in color, size, 
and form from the other varieties of this species. Cruenta 
shows a rather compressed abdomen which approaches that of 
pezomachoides , lending further emphasis to the close affinities 
of the two species. Our present insect, however, still shows 
that it belongs to the chestnut oak stock, for some of the indi- 
viduals of the type series have more cylindric abdomens than 
any specimens of pezomachoides I have ever seen.

FEMALE. — Head entirely dark rufous to piceo-rufous; the entire 
thorax and the legs rich, dark rufous; the mesonotum rougher and more 
hairy than m variety gemmula; the abdomen swollen cylindric, entirely 
black; medium sized insects, 3.2 to 3.8 mm. in length. Figures 370,

GALL. — Averaging nearer 8.0 mm. altho up to 14.0 mm. in diameter; 
always monothalamous ; on Quercus Michauxii and Q. Miihlenbergii.

Probably confined to the chestnut oaks in a more southern area of 
the Middle West, from southern Indiana to eastern Kansas, with the 
range centering in the Ozark areas. Figure 61.
