Notes on some Noctuid Larvae found about Newton, 



Mass. 



Ajyatela raddiffei Harvey. Color black. Three bright yel- 

 low lateral bands, the inferior about twice as broad as the two 

 superior ones : also a narrow dorsal band of the same color. 

 Eleventh and twelfth segments deep black above and separated 

 by a yellow line ; eleventh a good deal hunched. The whole 

 larva is sparsely covered with very small warts from which pro- 

 ject a few short, fine, dirty-white hairs mingled with a few 

 much longer ones. Legs black. Head black below and dull 

 crimson above, with a few projecting hairs. Length 37 mm. 

 Found on wild cherry (^Prunus serotina). One, taken before 

 the last moult, was light apple-green with a lozenge-shaped red 

 patch above, and could not be distinguished from the larva of 

 Ajjatela claresce^is. When at rest this larva elevates the fore 

 part of its body, bending back its head, so that it would easily 

 be mistaken for a young larva of Datana, which it almost seems 

 to mimic. It spins a slight cocoon composed of silk interwoven 

 with bits bitten out of the substance on which it spins. Before 

 spinning, the yellow lines turn milky white. The pupa is slen- 

 der and has a curious olive tint. The moth appears early in 

 June. 



Apatela spinigera Guen. Color blackish brown. On each 

 segment are eight warts from which project thick clusters of 

 bristly hairs, three on each side which are single, and two 

 above which are double and larger than the rest. On the first 

 and on the last two segments the hairs are dirty blackish, but 

 on the third the four upper tufts are deep crimson at the base 

 and become black at their extremities ; a few crimson hairs in
