4. Xematu8 ventralia Say. 
44 From my friend, Dr. E. K. Boardman, of Elmira, Stark County, I 
learned," says Professor Forbes, "on the 9th June that the common 
willow slag [Nematus ventrali* Say) had almost completely defoliated a 
fine tree of wild cherry on his grounds. The species has long been 
known as an enemy of the willow, but has not been heretofore reported 
as injurious to any fruit tree." 
."». Lyda fasciata Norton. 
Miss Mnrtfeldt reports in Bulletin No. 13 of the Division of Ento- 
mology, p. 59, the occurrence near St. Louis of the larvae of a Lyda 
marked in MS. by Professor Riley, who has often taken it around St. 
Louis, as Lyda cerasi, but which, he informs me, is in all probability L. 
Jasciata Norton. 
This is a gregarious web -worm, and its 
colonies covered quite large brauches 
with their brown, viscid webs, in which 
were mingled the castings and exuviae, 
forming altogether unsightly and dis- 
gusting masses, which greatly distigure 
the trees. 
Whether it is this or another 
species we do not know, but Mr. 
Howard L. Clark has presented 
me with several specimens of a 
Lyda larva (Fig. 183), which he 
collected from the wild cherry at 
Warwick, R. I. The body is short 
and thick, pale yellowish horn color ; head and prothoracic shield black- 
ish, as also the last segment of the body, including the slender 3-jointed 
caudal appendages; thoracic feet blackish. Length ll mm .

As observed by G. D. Hulst, the eggs were laid on the wild cherry 
in New York May 24 ; the larvae hatched May 30; they molted June 
1, second molt Juue 6, third molt June 11, fourth molt June 16, the 
caterpillar leaving its food -plant June 24. The moth emerged July 8, 
so that probably owing to the great heat of the season the whole life 
history of the moth was comprised in about six weeks. 
I have received specimens from Miss Morton of Xewburgh, N. Y., 
some of which in confinement at Brunswick, molted for the last 
time July 25, and others began to pupate, while August 3 and 6 
two moths emerged after being between two and three weeks in the 
chrysalis state. From one of them emerged a very large ichneumon
