Lepidoptera of New York and Neighboring States 



335 



superfamily YPONOMEUTOIDEA 



Head smooth, or nearly so, with a more or less distinct tuft on the 

 vertex in Argyresthia, Zelleria, and Acrolepia, but with shorter vesti- 

 ture than in any of the true Tineida?. Eyes moderate or small; ocelli 

 usually present and often conspicuous ; antenna? with pecten in some 

 cases, without eye-cap, the scape of moderate size, as a rule; shaft 

 with two rows of scales to each segment, the more basal always and the 

 other sometimes interrupted ventrally, varying from the condition of the 

 lower Tineids to that of the Maerolepidoptera. Palpi normally upturned 

 (minute and drooping only in Helioclines) with third joint nearly as 

 long as second, smooth scaled, long and conical or fusiform, never 

 drooping; second joint smooth-scaled or with various ventral tuftings, 

 but never with the roughly triangular vestiture usual in the Tortricida?; 

 without bristles. Maxillary palpi typically moderate and porrect, 

 rather bristle-like, often minute, folded in Acrolepia. Tongue normally 

 scaled, often strong, very rarely absent. Hind tibia? various. No 

 aculea? or ovipositor. Fore wing with R. running to outer margin 

 (except in the Heliodinidae) , but doubtful in some genera with reduced 

 venation ; R 4 and R- usually separate ; 1st A free, usually distinct 

 toward margin ; 2d A usually forked at base ; hind wing with Sc and R 

 closely parallel at base, usually connected by R 17 but sometimes sepa- 

 rate ; never anastomosing. Female with two bristles in frenulum. 

 Venation complete or nearly so. 



Larva? and pupa? various, though always showing the three prespira- 

 cnlar seta? in the larva. Cocoon very frequently lacelike of open meshes.

This superfamily, as here delimited, is a rather heterogeneous series 

 of forms which do not definitely belong to any of the other recognized 

 groups ; and the family separation here given is largely arbitrary
