LEPIDOPTERA OP NEW YORK AND NEIGHBORING STATES 87 



Superfamily Gelechioidea. Larva with setae iv and v closely approx- 

 imated or on the same tubercle, usually with developed prolegs ; pupa 

 obtect, maxillary palpi usually present, but pilifers not marked, and 

 front femora and labial palpi usually connected. Moth with all radial 

 branches running to costa as a rule, and usually all present ; R 4 and R 5 

 stalked except in Stenominae. Hind wing with Sc and R closely 

 approximate at base, separating before end of cell (shortly fused in 

 Blastobasidae). Head more or less smooth; palpi long and upturned, 

 maxillary palpi minute, .folded over base of tongue, which is scaled. 



Family 19. (Ecophoridae. Fore wing without stigma; Rj and Cu 2 well back from 

 end of cell; hind wing at least half as broad as fore wing, with apex of mem- 

 brane bluntly rounded; R and Mj well separated at origin; 1st A preserved in 

 both wings. 



Family 20. Xylorictidae. Fore wing without stigma; R, and Cu, well back from 

 end of cell, R and RS often separate, when stalked forking over apex; hind wing 

 broad, not excavated below apex, with R and Mj stalked. 



Family 21. Gelechiidae. Fore wing without stigma, R, and Cu 2 well back from 

 end of cell, R< and R 5 stalked or united, and both running to costa; hind wing with 

 R and Mj closely approximated or stalked, or with wing strongly excavated below 

 apex; 1st A lost in both wings. 



Family 22. Blastobasidae. Fore wing with a stigma between Rj and R 2 , which 

 are widely separated, veins R 2 to Cu 2 all closely crowded around end of cell. Hind 

 wing with Sc and R very shortly fused near base ; lanceolate, and rather narrower 

 than fore wing; R and M! well separated at origin. 



Family 23. Lavernidae. Fore wing without stigma, lanceolate, with 1st A vari- 

 able, sometimes anastomosing with 2d A. Hind wing much narrower than fore 

 wing, narrow -lanceolate to linear, pointed, with R and Mj strongly approximate 

 at origin, or stalked, and M 3 and Cu x usually widely separated. 



Superfamily Yponomeutoidea. Larva with setae iv and v variable, 

 pupa obtect in forms with iv and v separate, with maxillary palpi; 

 normally with labial palpi and femora exposed; pilifer not marked. 

 Moth with R 5 when present usually running to outer margin; maxil- 

 lary palpi usually small or minute, and porrect; hind wing with R 

 and M 1 variable, Sc and R approximate at base, and usually connected 

 by a cross vein. Head usually smooth. 



Family 24. Yponomeutidse. Ocelli small or absent; legs typically smooth- 

 scaled, venation but little reduced: fore wing usually with all veins separate; 

 hind wing with R and M t well separated except in the Cerostoma group, M t and 

 M, often stalked, 1st A distinct in both wings. Egg of flat type so far as known. 

 Larvae with beta lower than alpha on prothorax, prespiracular wart of three setae 

 and iv and v widely separate on abdomen. Pupa obtect, with maxillary palpi 

 exposed, pilifers represented by distinct lobes only in Atteva, and fore femora 

 exposed except in Scythris. (To this family are attached various isolated genera 

 of uncertain position.) 



. Family 25. Glyphipterygidse. Ocelli large and conspicuous, maxillary palpi 

 minute, tongue scaled, labial palpi upturned to middle of front or beyond, often 

 beyond vertex; wings exceptionally broad, macro -like in shape, the fringe rela- 

 tively narrow, and but little widened at anal angle. R and R, usually separate,
