the description. It appears to be a derivative of the Acrocercops 

 group. 



Leucospilapteryx Spuler. 



Type: Leucospilapteryx >)imssella Stainton. 



Head smooth. Antennae 1, base somewhat enlarged. Labial palpi 

 moderate; somewhat roughly haired, porrected, end joint equal second, 

 recurved. Maxillary palpi filiform, small, porrected. Hind tibiae with 

 row of bristly hairs above. Forewings elongate lanceolate; 11 more than 

 -3 of cell from the base and strongly joined to cell, 7 stalked with 8, or 

 absent, one dorsal branch from cell absent (possibly 3), 4 and 5 short- 

 stalked. Hindwings nearly linear, acuminate; 8 veins, 5 and 6 stalked 

 and joined to 7 by a cross vein near middle of wing. 



A genus derived from the Acrocercops group. 



Acrocercops Wallengren. 



Type: Acrocercops brogniardcllum Fabr. 



Head smooth. Antennae more than 1, labial palpi long, curved, as- 

 cending, tufted beneath on second joint, terminal joint equal to second, 

 pointed. Maxillary palpi filiform, porrected. Posterior tibiae with row of 

 , bristly hairs above. Forewings elongate and acuminate; 12 veins, 2 

 weak toward its base, 5 and 6 stalked ; (In Dialectica, Wlsn, 6 is stalked with 

 7), origin of 11 distant from base of cell. Hindwings about one-half, narrow 

 lanceolate; 8 veins, 5 and 6 stalked and connected to 7 by cross vein. 



The above description is given from a European specimen of 

 the type species, and is very much more restricted than that given 

 by Meyrick in the Gens. Ins. 



Chilocampyla Busck. 



Type: Chilocampyla dyariella Busck. 



Head smooth. Antennae nearly H, basal joint somewhat flattened 

 and enlarged with a projecting flap of dense scales. Labial palpi long, 

 smooth, curved, subascending, pointed. Maxillary palpi filiform, mod- 

 erate, porrected. Middle tibiae thickened with heavy tuft of scales. 

 Posterior tibiae with double row of bristles above. Forewings elongate 

 lanceolate; 12 veins, 2 weak, 6 and 7 stalked, 11 from toward middle of 

 cell margin (10 in cf obliterated by a costal depression). Hindwings ^, 

 linear; 8 veins, 5 and 6 stalked. 



A genus related to Acrocercops Wallgr. both by venation ;ind 

 hind tibiae. Separated from this genus by its flap of scales at 

 the base of the antennae and thickened middle tibiae.
