At this point it accidentally dropped to the ground, a dis- 

 tance of four feet: its skin was broken by the fall. However, 

 though apparently dead the next day, on July lO and 15 it 

 had seemingly recovered and turned very dark on July 17. At 

 8 A. M., July 18 the butterfly was trying to emerge, but did 

 not succeed in doing so. The wound delayed the develop- 

 ment greatly, it seems, and finally killed the insect. The hiber- 

 nacula of this species are constructed of a single willow leaf 

 with its faces folded together and tied there by silk. The hi- 

 bernating larvae leave them, by means of a comparatively large 

 gaping hole at the distal end. In the same locality, chrysalids 

 of this species have been seen in May.

Seven adults of this parasite, including both sexes, were 

 reared from the eggs of Arilus cristatus (Linnaeus) collect- 

 ed at Annapolis, Maryland, December 26, 1903. The para- 

 sites emerged at Paris. Texas, April 1-12, 1904. They were 

 identified by William H. Ashmead. The host eggs were on 

 peach. 



15. Dryocampa rubicunda (Lepid,). 



An eggmass of this species was found at Blacksburg, \'ir- 

 ginia, August 3, 1902, on the under surface of a leaf of maple. 

 They were in a single layer, the mass round in outline, large, 

 concaved, ^\'hen ready to hatch the eggs are pale, the per- 

 fect embryo distinctly visible ; the exit-hole is crescentic and 

 on the side over the embryo's head. After desertion, the 

 eggs are transparent, like small capsules of gelatine. The mass 

 contained about forty eggs. On August 6, larvae were pres- 

 ent on maple in all stages. One colony had just hatched, an- 

 other about half-grown, while some appeared to be nearly 

 full grown. These were all in the same tree. The young 

 larvae have black heads, the old ones red, the most striking 

 difference between them. When first hatched the larva is 

 pale yellow tinged with green : bead and legs black ; the pro- 

 legs pale yellow ; two small, black hornlike processes are borne
