2O8 ENTOMOLOGICAL NEWS. [May, 'l2 



very slender, faintly greenish, almost transparent. Head small 

 and of the body color. All were found resting lengthwise along 

 the underside of the small locust thorns, well color-protected. 



A large 77/a-like egg found on the underside of hickory 

 bark, hatched on the 3Oth of April. The young larva was 

 slender, gray with a tinge of green and with black cross bands. 

 Very noticeably bristly. Head black. It refused hickory and 

 fed on bur oak but died without moulting. In searching for 

 Catocala eggs under the bark of shagbark hickory we had oc- 

 casionally found dead eggs, large and elliptical, apparently of 

 ilia. The live egg mentioned and found the winter before, 

 gave an ilia larva. 



Why are these eggs laid on a tree whose leaves the worm 

 can never eat? Dead egg shells are not uncommon but never in 

 crowded or overlapping masses as in the case of palaeogama 

 and other hickory feeders. 



A minute, distinctly reddish egg, ribbed as in Catocala, and 

 found under hickory bark, hatched but was lost. It was prob- 

 ably Judith. 



The ilia and other eggs for rearing, were kept from hatch- 

 ing for nearly a month, on a cold cement floor and the experi- 

 ence was the same as in past years, the larvae did not thrive. 



The young ilia larvae feed best on bur oak buds. They often 

 refuse the leaves till they are well grown. The first imago of 

 Actias selene cut through its cocoon, May 6th. 



The cocoons of Caligula cachara, Cricula trifene strata, An- 

 therea roylci and Actias selene were furnished the senior author 

 by Mr. James L. Mitchell of Indianapolis. An overlapping 

 mass of white eggs, found under hickory bark, hatched on the 

 gth of May. 



Eggs of Catocala innubens began hatching May 7th and 

 eggs of C. flebilis, furnished by Mr. Ernest Schwarz of St. 

 Louis, on May loth. Eggs of C. retecta began hatching on 

 May nth and those of C. vidua and C. nebulosa on the I2th of 

 the same month. Part of the retecta eggs were furnished the 

 senior author by the junior and all of the nebnlosa by Mr. 

 Harold Davenport.
