THE LEPIDOPTERIST 69 



on it at all, and was a much blacker looking worm 

 owing to the heaviness of the black spots and the ab- 

 sence of the brown. The line down center of head 

 was not so heavy as in the nuptialis larvje and was 

 broken in the middle. The large one died when two 

 inches long and the two small one were parasited. 

 Were they larvse whitneyi or abreviatella? Nuptialis 

 appears here on the wing about a month later than 

 the other two, but we have taken belated specimens 

 of whitneyi along with the first nuptialis. 



To our great disappointment we were unable to get 

 any of these wild larvae through. A large number of 

 them were parasited and the others died. This seems 

 to be a very delicate species as we were only able to 

 rear to maturity one nuptialis from nine hatchlings. 

 This was not due to lack of care, for a "million dollar 

 baby" never got better care than this interesting 

 family of worms. 



The growth of the larvae hatched from the eggs was 

 so slow and they seemed so delicate that we were in 

 doubt as to whether they were getting the proper food 

 plant, but finding them in such numbers on Amorpha 

 fruticosa established it as their true food plant without 

 question. 



Mr. Dodge says that in Nebraska where Amorpha 

 canescens was common these three species were also 

 common, and where it was scarce they were feeding 

 on canescens. After finding them on A fruticosa 

 we examined a lot of A. canescens, but failed to find 

 any, and the canescens or "shoe string" showed no 

 signs of having been eaten. 



Drawings of egg and head were made by Mr. E. A. 

 Dodge from eggs, a cast head and description of 

 head sent him by us. Photographs of larvae by Frank 

 Tngalls.
