Kinsey : Gall Wasy Genus Cyniys

But if the eastern species have long been known, their 
generic relations have been most variously interpreted. This 
has been because some of the varieties are long-winged insects 
while others are short-winged insects with consequently modi- 
fied thoracic and abdominal characters and strangely trans- 
formed hypopygial spines. Eight of the short-winged agamic 
forms have been assigned to Acrasyis (or included under Phi- 
lonix) , one of the short-winged forms was the basis of the 
generic name Syhaeroteras , the single long-winged eastern 
variety was with some doubt assigned to Dryoyhanta (or 
“Diyloleyis”) , but the bisexual form of one of the short-winged 
varieties was recognized as a good Dryoyhanta (= our present 
Cyniys), The long-winged agamic females of the Southwest 
were labelled Dryoyhanta , even tho the gall of one of these 
inspired the name acrasyiformis. 
With this background, the recognition of short-winged and 
long-winged varieties in the single species villosa has left no 
room to question the close relations of the species that have 
passed as Acrasyis and Dryoyhanta . Villosa was first known 
from two short-winged varieties that have commonly been 
accepted as congeneric with yezomachoides, the genotype of 
Acrasyis . But another variety of villosa, namely exyositor, 
described in the present paper, is found in a gall closely simi- 
lar to those of varieties villosa and alaria. The insect of 
exyositor has long wings and other characters that show it to 
be a geographic segregate of the long-winged, acrasyiformis 
stock. 
This close relation of long-winged and short-winged varie- 
ties is shown so often in the present paper that it would be 
readily acceptable in Acrasyis except for the fact that all the 
long-winged varieties have pointed, slender, plough-shaped 
hypopygial spines, while twenty-three of the short-winged va- 
rieties have blunt spines of uniform width. When I first saw 
this, I had not recognized such variation in the hypopygial 
spine in any other group of gall making cynipids, and I hesi- 
tated for many months to accept it in this group until I became 
convinced that both types of spine occur within the single 
species villosa . 
This conclusion is re-enforced by a detailed examination of 
the galls of the agamic forms of Acrasyis. While the large 
and densely woolly galls of the long-winged nubila seem at first 
glance very different from the naked, faceted galls of the short-
