distinct or obsolete discocellulars. Hindwings with vein 8 (and 

 7 if present) free to the base not connected with cell. 



The mouth parts are so degraded that it is hard to homologize 

 the existing structures with those of an ordinary Tineid. The 

 slig'ht projection densely covered with scales and visible just be- 

 low the clypeus, is seen, if denuded, to be a single piece with 

 emarginate apex, divided by a suture from a basal portion, which 

 occupies the middle of the head beneath. This structure resem- 

 bles a simple labium in many insects, but its position seems that 

 of the base of the proboscis of ordinary moths. The labrum lies 

 ii! the deep emargination of the clypeus, and no other mouth- 

 parts are present.

4. (3) Forewings with veins 7 and 8 basally approximated but 



distinct Hetcropsychc 



PaJaeo psyche, gen. no v. 



Forewings with 2 very distinct internal veins, vein 2 rising 

 from cell far beyond the middle, widely separated from 3, being 

 about as distinct from it as 3 is from 4; 7 and 8 very closely ap- 

 proximated at base, t'he cell apparently open at the apex, being 

 only closed by obsolescent veins; vein 12 free. Posterior wings 

 with only 6 veins in addition to the internal, vein 4 being absent; 

 apex of cell an acute angle giving rise to vein 5 only; 7 and 8 

 free to the base. (PI. fig. 3.) 



Palacopysche melanias, sp. nov. 



Male and female, 7-8.5 mm. Head and thorax black, some- 

 what hairy, antennae more or less pale, black or dark at the 

 points of origin of the pectinations. Antennae in the male with 

 g very long bipectinations, and the apex bifid to form a tenth, 

 the longest pectination about half as long as the whole antenna;
