leuca, since that genus is allied to Adoneta as adult moths. We 

 were not then successful in rearing the new larva. It is referred 

 to in print^'* as Monoleuca ( .?), as I then thought it might be. Sub- 

 sequently, in arranging the collections at the National Museum 

 at Washington, I found an inflated larva of this new form, together 

 with a bred female adult, prepared by Mr. A. Koebele, formerly of 

 the United States Department of Agriculture. The adult was 

 not Monoleuca, but a light-colored form of Adoneta, which I supposed 

 must be Packard's leucosigma, though I could not be sure that the 

 new larva properly belonged to it, not finding Mr. Koebele 's notes. 

 On the strength of this specimen, I listed leucosigma as a variety 

 of spinuloides.^^ In 1903 and 1904 Mr. W. F. Fiske, of the Forestry 

 Division of the Bureau of Entomology, was collecting at Tryon, 

 N. C, and he turned up Monoleuca semijascia in numbers. At 

 my request, Mr. Fiske secured eggs, but they all proved infertile. 

 In the fall of 1904, therefore, I went to Tryon for the purpose of 

 finding the Monoleuca larva. I was unsuccessful; but in the search 

 obtained a number of larvee of the new form of Adoneta. In the 

 same season a number of adults were collected at Plummer's Island 

 in the Potomac River, near Washington, by Messrs. August Busck, 

 H. S. Barber, and E. A. Schwarz, and it became evident that I 

 had before me an undescribed species of Adoneta, which was not 

 leucosigma Packard. I therefore published a description of it, 3° 

 associating with it the new larva. 



The larvae from Tryon resulted in several male and one female 

 moths in July, 1905. The males emerged before the female, and, 

 in flying in the cage, lost their legs, so that they quickly destroyed 

 themselves by buzzing on the ground. When the female emerged, 

 I had no living male left. I placed her in the cage at Rock Creek, 

 near Massachusetts Avenue, in the District, but no male was at- 

 tracted. The next night Mr. H. S. Barber kindly took the cage 

 to Plummer's Island and remained there all night, but again with- 

 out success. However, Mr. Barber took at light two males of 

 this species, which he kept ahve in glass tubes. One had lost its 

 legs and was useless, but the other was in good condition and was 

 placed in the cage. Mating occurred on the third night after emer- 

 gence of the female, and good eggs were secured.
