spun up iu moss of the breeding jar. It pupated four days 

 later, and the moth emerged Xov. 19, after three weeks in the 

 pupal stage. 



I have named this moth for Dr. Perkins, who was with me 

 when I found the iirst specimen, and at once recognized it as 

 different from the known species. The specimen, however, was 

 too much battered and abraded for description. This is now 

 made possible by the reared specimen in good condition, and 

 the fairly good specimen collected by ^Ir. Bryan. 



XoTE. — Recently the Bishop Museum has received, by 

 way of exchange, a pair of Celrrio galJi intermedia Kirby 

 from Mr. B. Preston Clark of Boston. These specimens were 

 collected in Alaska. The species is widely distributed in 

 Xorth America. 



Comparing these with the Hawaiian Celcrius. there is a 

 striking similarity in the color patterns of the wings, and the 

 abdominal markings. The similarity is most striking with 

 our C. calida (Butler). It seems to me to indicate the 

 American origin of the ancestors of the Hawaiian Celerios. 

 Mr. Clark, in letter, also concurs in the belief that the Ha- 

 waiian Sphingidae are allied to those of America.
