were fed with oak, maple, raspberry, willow, poplar, hazel, rose, sumach 

 and fir leaves, but they did not eat them. On being taken up, tlie freshly 

 hatched larvic spun a thread by which they let themselves down. 



Egg. — Round, with the surface granulated ; of a dirty wiiite, clouded 

 with reddish brown. They are laid separately in an irregular bunch. 



Larva directly after Hatching.— {F\g. 22.) Length, 3 mm. The head 

 is large, as wide as the prothoracic segment, dark brown, with two trans- 

 versely oval light-gray spots above ; along the front edge of the epicra- 

 nium is a broad gray stripe, and at the base of the labrum is a transverse 

 less distinct pale band. 



The prothoracic segment is very large, slightly wider than the head, and 

 from this segment the body tapers to the end. On each side of the pro- 

 thoracic segment, and projecting outwards, is a large piliferous amber- 

 colored tubercle, which is three times as large as those behind it on the 

 succeeding segments. Between these are two minute dorsal piliferous 

 tubercles. On each side of the second and third thoracic segments is a 



lateral amber-colored piliferous tubercle, while the dorsal tubercles be- 

 tween are rather larger than the lateral ones. On the abdominal seg- 

 ments the dorsal tubercles are amber-colored, becoming dark on the ter- 

 minal segments, while the lateral tubercles are dark, concclorous with 

 the body. The hairs are gray and dusky, those on the large lateral tuber- 

 cles the longest and curved forwards in front of the head. Behind these 

 the longest hairs are a little longer than the body is thick. Tiie body is 

 dark. On the abdominal segments the dorsal tubercles are amber-colored, 

 becoming dark on the terminal segments, while the lateral tubercles are 

 dark, concolorous with the body. The hairs are gray and dusky, those 

 on the large lateral tubercles the longest, and curved forward in front of 

 the head. Behind these the longest hairs are a little longer than the body 

 is thick. The abdominal legs are long and slender, spreading outward 

 beyond the body. The eighth pair of dorsal abdominal tubercles are a 

 little larger than the others. 



In general appearance, viz., the large, broad, first thoracic segment, the 

 body tapering backward from it, and the large prominent lateral piliferous 

 warts, one on each side of the segment, this larva is a true Lasiocampid,
