moult, except a few Piitnatni, which, at this stage could not be 

 distinguished from contexta, unless, perhaps, by a slight, blackish 

 dorsal shade. Their death seemed to be the result of two causes — 

 bleeding through the rupture of the integument while shedding 

 the skin, probably the result of too much moisture, and blacken- 

 ing, probably caused by some fungus. I have been somewhat 

 troubled by entomophthrous fungi in rearing moths, especially 

 by a species of EntoniopJitJiura allied to radicans, which attacks 

 hairy caterpillars with great rapidity while feeding. Another 

 mold has recently almost wholly destroyed a brood of IcJithyiira, 

 portions of the body blacking and producing a white mycelium, 

 Avhile the larva; were still living, though unable to eat. I have 

 not met with the species of Torrubia, except in the supposed coni- 

 dial form. In addition to these I have found several species of 

 Miicor and Penicilliiim very destructive among winter pupae. 



Of the Plusia above described, about ten imagos were ob- 

 tained from a brood of several hundred. There are probably 

 three or four,broods of this species in a season, though there is little 

 or no regularity in the appearance of the imago, as both this species 

 and Putnavii may be met with at any time from June to the 

 middle of September. It is probable that a portion at least 

 of the July broods of Plusia hibernate with the August and Sep- 

 tember broods, as the only survivor of my brood of ainpla 

 became torpid after the fourth moult and continued in this con- 

 dition till the first of October, when it died. The following is a 

 list of the species of Plusia that I have taken in this locality. P.

NOTES ON THE GENUS CLISIOCAMPA. 



By R. H. Stretch. 



When at Astoria, Oregon, on the 17th of June last, T found 

 the larvae of two species of Clisiocainpa infesting the orchards at 

 that place, one of them excessively abundant the other in much 

 smaller numbers. As we were traveling very rapidly and I had 

 no opportunity for a week to examine and feed the larvae I only 

 succeeded in raising one of the species, and of that but few per- 

 fect specimens. I here give such notes as I have of their trans- 

 formations. 



Larva No. i. — Similar to that of C. Californica in size and 

 general appearance, but strikingly brighter colored. Length \y^ 

 to I ^ inches. Dark brownish-black. Prolegs black ; abdominal
