FEMALE. — Head (including the basal halves of the antennae), 
thorax, legs, and abdomen bright brownish rufous, darker to rufo-piceous 
in only a few places; head about as wide as the thorax; parapsidal 
grooves moderately convergent at the scutellum ; foveae entirely smooth 
at bottom; wings slightly shortened, 1.15 of the body in length, extending 
well beyond the tip of the abdomen; first abscissa of the radius angulate 
at more than 90°; second abscissa of the radius only slightly enlarged 
but still angulated at the tip; radial cell short but rather longer than 
wide; areolet of moderate size; the spots in the cubital cell well removed 
from the basal blotch in the cell; length 2.1 to 3.3 mm. Figures 268, 
277. 
GALL. — As described for the species, galls thus far collected being 
rather small (up to 15.0 mm. in diameter), with dull surfaces; on 
leaves of Quercus mexicana and other white oaks. 
RANGE. — Mexico: San Luis Potosi (Ed. Palmer, in M. C. Z. and 
Kinsey coll.). Mts. of Guana juanto (Duges in U.S.N.M.). 
Probably confined to an area in more central Mexico. Figure 44. 
TYPES.— 3 females in the Vienna Museum (acc. F. Maidl in litt.) . 
From Mexico (locality not given); on Quercus mexicana; Dr. Duges 
collector. Insects and galls from the same collector, from the Mts. of 
Guanajuanto, are in the U.S. National Museum. 
I have examined this material in the National Museum. 
Mayr gave Q. mexicana as the host of the type material, 
and his illustration more nearly matches mexicana than the 
black oak, hypoleuca, to which Beutenmiiller referred it. My 
specimens were on an oak more closely related to Q. oblongi- 
folia (which it is not) . If Mayr’s host reference is correct, 
then mexicana is a white oak arid not a black oak as Trelease 
lists it (Nat. Acad. Sci. Mem. 20 :173) .
