This conspicuously mai'ked caterpillar, shown, together with the 



moth produced by it in 



Figure 18, which is so 



injurious to many kinds 



of vegetation, has often 



been described and figured 



in its mature form, but 



only a few brief notes of 



its earlier stages have been 



given. Examples sent by 



Mr. George T. Powell, 



from Ghent, N. Y., June 8, 



1887, found feeding in 



company on a currant 



bush, enable me to sup-

The Young- Larva, 

 The larvse were 0.35 inch in length, and cylindrical in form. The 

 head is pale red, and nearly as broad as the body. The body is 

 traversed dorsally by a bluish-white mesial stripe, excei^t as it is 

 interrupted at the incisures on the posterior segments by the coales- 

 cing of the two well-defined black stripes that, commencing on the 

 white collar of the first segment, elsewhere border it. Below this is a 

 distinct bright yellow subdorsal stripe, broader than the black one 

 above it, in which, on the hinderpart of each segment, is a small, 

 black setiferous tubercle— its seta a little longer than the breadth of 

 the stripe ; these tubercles, on the posterior segments, are merged
