of the same hue reaching to the fold and pointing towards a spot of the 
same hue just within the fold ; a small spot of the same hue about the 
middle of the costa, behind which is an irregular costal streak of the same 
hue which extends to the middle of the apical portion of the wing and. 
widens into a large irregular spot ; in the apical part of the wing is an 
indistinct /orgifudinal dorsal streak, nearly opposite to which, but a little 
behind it, is a larger and more distinct streak which is also longitudinal. 
All of these spots are mixed with or margined by reddish yellow scales ;. 
ciliae white dusted with dark brown. ÆA/arex. 7% inch. Kentucky. 
The three foregoing species thus resemble each other and differ from 
the others in ornamentation as well as inthe structure of the antennae. 
They were all three taken in the same situations. 
ON WME, EHABIES OF CERTAIN GALL, INSECTS OF TEE 
GENUS. CYNIPS. 
BY H. F. BASSETT, WATERBURY, CONN. 
For ten years past I have been studying the habits of the Cynipidæ 
to determine, if possible, whether there are one or two broods of these 
insects each year. 
Several years ago I discovered the flies of C. g. operator in the act of 
ovipositing in the young acorns of Quercus ilicifolia, the oak on which the 
woolly galls of this species are generally found. The insect thrust its 
ovipositor down between the acorn and the acorn cup, and, late in the 
summer, the acorns thus stung proved abortive, while around them and 
often protruding far above the cup were little acorn-like galls, each con- 
taining a large Cynipideous larva. Several of these galls were often 
found in each acorn cup. ‘That year nearly all the acorns were affected, 
and there are more or less thus injured every year. 
I have as yet failed to rear any flies from these galls, probably because 
I have failed to keep the galls in the proper condition for developement. 
A later discovery, made three or four years ago, was that of two, and I 
think three species of Cynips in the act of ovipositing in the buds of the 
oak, Q. alba, just as the buds began to develope, but before the leaves 
were visible.
