NORTH AMERICAN LASPEYRESIINAE AND OLETHREUTINAE 3 



tricoidea, however, is eclectic and the classification incorporates the 

 systems of several authors. 



Kennel's monograph of the European Tortricoidea,^ mention of 

 which was unfortunately omitted from Bulletin 123, deals only with 

 such American species as are common to the two continents. It is an 

 elaborate work with full specific descriptions and fine color figures 

 of the moths. There is a detailed discussion of phylogeny and struc- 

 tural characters and numerous figures of the latter, but no keys 

 specific or other. The genitalia receive only occasional mention and 

 the classification departs but little from the Heinemann system. 



CLASSIFICATION 



In as much as a full family description and a key to the subfamilies 

 are given in Bulletin 123, it will be necessary here to note only a few 

 emendations. In my definition of the family I described vein 2 of 

 fore wing as "from the cell before outer three-fourths." This char- 

 acter holds for all the American species except hemidesma Zeller 

 Avhich I am making the type of a neAV genus {Evora). Here 2 comes 

 from cell well beyond three-fourths as in the Phaloniidae. On gene- 

 talic and other characters, however, Evora is a perfectly good Ole- 

 threutid and goes in the Olethreutinae. Absence of the pecten on the 

 lower median vein of hind wing should also be noted in three genera 

 of the Laspeyresiinae {Goditha^ Satronm., and Sereda). In males of 

 the laspeyresiin genera Hemhnene and Balbis vein 8 of hind wing is 

 not free, but either fuses with 7 beyond cell {H eviifnene) or (in 

 Blabis) anastomoses with it from slightly beyond base to w^ell beyond 

 cell, somewhat as in the Pyralidae. Such exceptions make it practi- 

 cally impossible to frame a definition that will hold throughout for 

 the family unless we include characters of the male genitalia. On 

 these organs, however, the definition is clear-cut and permits of no 

 confusion. The Olethreutidae is a natural, well-marked family, much 

 easier to recognize than to describe in categorical terms. 



The subfamilies also appear to be natural groups, in the main 

 clearly defined on hind wing venation; though here it is also neces- 

 sary to note a few exceptions. Some of the genera {Pseudogalleria 

 in the Eucosminae, Endothenia.^ Esia^ and Episwmis in the Olethreu- 

 tinae, and Gynmandrosama and Ecdytolopha in the Laspeyresiinae) 

 are obviously transitional and on some of their characters could go in 

 other groups. Pseudogalleria has the reduced genetalia of the Las- 

 peyresiinae and the hind wing venation of the Eucosminae. On the 

 sum of its characters it seems to go better in the latter subfamily than 

 elsewdiere. Another genus of the Eucosminae {Gwendolina) has 

 veins 3 and 4 of hind wing connate and 5 approximate to 4 at base,
