I Lave named rliis moth for Dr. Perkins, who was with me 

 when I found the tirst 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 Itv the reared specimen in good condition, and 

 the fairly good specimen collected by Mr, Bryan. 



XoTE. — Recently the Bishop Museum has received, by 

 way of exchange, a pair of Cclcno (/alli intermedia Ivirby 

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

 ^N'orth America.

 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. 

 ]\rr, Clark, in letter, also concurs in the belief that the Ilti- 

 waiiau Spliingidae are allied to those of America.
