NORTH AMERICAN EUCOSMINAE, 245 



light form {fragariae) however has been taken in Colorado and as 

 far north as South Dakota and has been reported from Canada which 

 would extend its range as far north as that of the dark typical 

 Gomptana. I do not know how the varieties run according to food 

 plant, as nearly all the reared specimens from strawberry and rasp- 

 berry in our collections are of the fragariae variety. All the Euro- 

 pean specimens in our collection are the dark form, and all the 

 typical corresponding American specimens of northern distribution, 

 that I have seen, are collected specimens without food plant data. 

 There are no genitalia differences distinguishing the supposed races, 

 and the probabilities are that at most we will be able to recognize 

 but two forms a light and a dark with pretty general distribution. 

 For the present, pending further rearings, I am keeping the several 

 names as racial designation, applying Walsinghams' cometana to 

 the dark western form. This was described as a distinct species. 

 His figure is very poor but the description fits very well the dark 

 form of comptana. I have seen nothing else to which it could apply. 



Distribution according to specimens in National Collection, Ameri- 

 can Museum, and collection Barnes : Pennsylvania, New Jersey, New

Phoxopteryx cometana Walsingham, Illus. Lepid. Heter. Brit. Mus., vol. 4,

This is probably nothing but a synonym of co'mptana\ but in as 

 much as we are holding fragariae and floridana as races the name 

 may be retained for dark western specimens of compta^na.
