Cynips hirta variety obtrectans, new variety 
agamic form 
Figures 70, 381, 425 
FEMALE. — Color bright brownish rufous, the antennae also brown- 
ish rufous, darker only toward the tips; bright yellow- rufous on most 
of the mesonotum, on most of the second abdominal segment, and on 
other large areas on the abdomen postero-ventrally; lateral lines prac- 
tically absent; abdomen relatively larger than in macrescens; wings 
0.35 of the body in length, extending fully one-half of the way along 
the second abdominal segment; 2.2 to 3.5 mm. in length, normally larger 
than macrescens. Figures 381, 425. 
GALL. — More ellipsoid than spheroidal; up to 5.5 mm. in length; 
the faceted surface distinctly smooth in appearance; on leaves of Quer- 
cus macrocarpa. 
RANGE. — Texas: Austin (types; Patterson coll.). 
Oklahoma: Pawnee. (Kinsey coll.). 
Kansas: Winfield and 10 miles southeast of Winfield (galls, R. 
Voris in Kinsey coll.). 
Probably confined to eastern Texas and Oklahoma, or perhaps ex- 
tending due east from that area as far as the host, Q. macrocarpa, 
occurs. Figure 70. 
TYPES. — 2 females and 3 galls in the Kinsey collection. Labelled 
Austin, Texas; insects cut out of galls October 26, 1921; Q. macrocarpa; 
J. T. Patterson collection number 136. 
This is the more southern of the burr oak varieties of hirta. 
The present insect is distinct enough from the more northern 
varieties macrescens , scelesta , and opima, to allow certain de- 
termination. I have only one immature adult from the mate- 
rial I collected in 1920 at Pawnee, Oklahoma, but it shows 
the coloration and the lengthened wings of the types from 
Austin, Texas, and I take it that the range of the variety is 
largely east and northeast from Austin. 
Dr. Ralph Voris has collected young but full-sized galls, of 
this species but doubtfully of this variety, in southeastern 
Kansas as early as June 6, 1927. At that time the larvae 
were still microscopic in size. Dr. Patterson collected the 
type galls in the fall of 1921, cutting two mature (one not 
fully pigmented) and live adults from the galls on October 26 
of the same year.
