larval cases lengthen from their distal end and push the woolly 
substance out into point-like protuberances. The galls turn 
brown when maturing. They may also be found along the side 
of a twig, in one case the receptacle being formed on a develop- 
ing bud. The eggs of this cynipid are probably deposited 
within a bud. The galls are large and conspicuous, flower-like 
at times and bitter to the taste. There are commonly two re- 
ceptacles, side by side, in the place of the two apical buds of 
the twig. 
The young larval cases are seedlike and measure about 
three millimetres; they taper at the distal end and each bears 
a tuft of woolly substance. In the mature galls each case has 
become elongated into fleshy spokes, green and herbaceous, 
which measure about thirteen mm. in length, about half of 
which is the elongated distal end. 
The adults issue through large holes at one side of the 
distal extremity of the larval case (the basal, swollen, seed- 
like portion of it) and tunnel their way through the surround- 
ing substance to the open air, leaving for the time being a 
small shotlike hole; these soon close up owing to the nature 
of the gall substance. The adults emerge for a period of at 
least two weeks. The gall also occurs at Cumberland, Mary- 
land. 
Parasites are numerous; a golden-haired Eurytomid was 
reared from the Virginia specimens. 
6. The Galls of Rhodites bicolor. (Harris) (Hym.). 
On July 5, 1903, a number of the characteristic galls of this 
species were taken from wild Carolina rose growing in a 
boggy meadow near Blacksburg, Virginia. The cynipid larvae 
were then present and parasites had been emerging for some 
time. During the same year, though its host plant was abund- 
ant, the galls were rarer at Cumberland, Maryland, than in 
Virginia. 
ihe Diastrophus nebulosus. (Hym.). 
This common gall of blackberry has been observed at An- 
napolis, Sparrow’s Point (Baltimore) and Cumberland, Mary- 
land; Ridgeley, West Virginia; Blacksburg, Virginia, and 
Parts. bexas,
