2 BULI.ETIN 132, UNITED STATES NATIONAL. MUSEUM 



National, American Museum, and Barnes collections. Published 

 records which I have been unable to verify are omitted. 



Food plant records are also given for each species, where known. 

 When such references are omitted the food plant is presumed to 

 be unknown. 



Thirty-five genera, 223 species, and 9 varieties are recognized as 

 belonging to the two subfamilies. Of these, 16 genera, 34 species, 

 and 3 varieties are described as neAv. Five species noAv listed in the 

 Olethreutinae, but Avhich must be referred elsewhere, are briefly 

 treated at the end of the paper. 



HISTORICAL REVIEW 



It is necessary here to call attention to three important works deal- 

 ing with the family and not mentioned in Bulletin 123. AVhile the 

 latter was in press an extremely interesting paper by F. N. Pierce 

 and J. W. Metcalfe^ appeared, figuring the male and female geni- 

 talia of the British Tortricoidea, describing these organs in detail 

 and proposing a classification for the group upon purely genetalic 

 characters. It is a valuable work and I would acknowledge my in- 

 debtedness to it. Unfortunately the authors ignored all other charac- 

 ters of the insect except genitalia and as a result have made some un- 

 natural groupings. In the Olethreutidae they make six group divi- 

 sions corresponding roughly to our three subfamilies, as follows : 

 Their Olethreutidii to our Olethreutinae ; Ancylisidii and Epiblemi- 

 dii to part of the Eucosminae ; Lipoptychidii to part of the Laspey- 

 resiinae; and their Ephippiphoridii (a heterogenous group) to the 

 remaining genera and species of our Eucosminae and Laspeyresiinae. 

 Their divisions are made entirely upon the form and number of the 

 signa of the female bursa, characters of generic rather than sub- 

 family value, and which do not hold even for the groups as they de- 

 fine them. Thorn-like signa are found in the Laspeyresiinae, Ole- 

 threutinae, and Eucosminae (Epiblimidii) ; and the transitions from 

 pocket to thorn-like and from thorn-like to " pilleate '' shapes are 

 gradual and nowhere clearly marked except between species or, at 

 most, genera. 



Recently Dr. W. T. M. Forbes * has published a handbook of The 

 Lepidoptera of New York and Neighboring States, with generic and 

 specific keys and descriptions of the species occurring in the North- 

 eastern United States. In this the Olethreutidae are treated as a 

 subfamily of the Tortricidae. Most of the genera defined in my Re- 

 vision of the Eucosminae are retained and the classification there pro- 

 posed is more or less followed. The general treatment of the Tor-
