RANGE. — Florida: Bowling Green (Kinsey coll.). 
Probably confined to Q. minima on the peninsula of Florida and an 
adjacent area in Georgia. Figure 53. 
TYPES. — 1 female and 1 gall in the Kinsey collection. Labelled 
Bowling Green, Florida; gall November 13, 1919; Q. minima; Kinsey 
collector. 
While this insect is in color very different from all of the 
other varieties except mellea and bifurca , it is not more than 
varietally distinct from Carolina, compta, and the other rufous 
and black insects. It is interesting to find both of the de- 
scribed varieties from Florida light yellowish rufous in color. 
Variety mellea is described from Q. stellata, and the present 
insect, concolor, is from Q. minima . It may be this host isola- 
tion that keeps the two varieties distinct, for Q. minima is a 
live oak and does not belong to the Q. alba and Q . stellata 
groups of oaks that are common in the Southeast. 
It is to be regretted that we have so little material of 
concolor .

antennae and the legs with the coxae, the abdomen more yellowish 
rufous; thorax reduced, narrow, the mesonotum largely smooth and 
shining but very minutely roughened and sparingly hairy; anterior
