30 BULLETIN 133, UNITED STATES NATIONAL MUSEUM 



A species of some economic importance as an enemy of apple. 

 The larva is apt to be confused with that of molesta which it much 

 resembles. It usually attacks the growing twigs, seldom the fruit. 

 It has also been reared from rose tips and there are a couple of 

 doubtful records from peach. 



The adult is smaller than that of nwlesta and has a faint but 

 distinguishable dark median fascia on fore wing. Its most striking 

 character, however, is a strong patch of blackish sex scaling upon 

 the upper surface of the hind wing and a similar patch on the under 

 surface of the fore wing of the male. This character as far as I 

 know is shared by no other North American species of Grapholitha 

 or Lespeyresia, Zeller's type, unfortunately, is a female; but I do 

 not think there can be any doubt of its synonymy with Miss Murt- 

 f eld's species. 



Hind wing with veins 3 and 4 connate. 



Genitalia figured from specimens in National Collection from 

 Plummer Island, Md. (Busck, July, 1903, male) and Missouri 

 ("368-M," "5-2-07" reared from "rose tips," female).
