curved; the penis is only a little broadened and with only small 

 spines below tip ; the titillators are fairly stout, with a sinuous curve 

 before the swollen, pointed tip. 



Length of f orewing, 21 to 23 mm. ; width, 5 to 7 mm. 



From Suifu, Szechwan, 1,000 feet, November 5, several specimens. 

 Holotype, U.S.N.M. No. 53163. Paratypes in U.S.N.M. and M.C.Z. 



STENOPSYCHE PJASETZKYI Martynov 



Plate 2S, Figubes 21, 22 



One male from near Suifu, June 15, 1,000 to 1,200 feet. 



A small species, f orewings of this specimen 17 mm. long ; f orewings 

 generally resemble those of /S. laminata and S. moselyi. The genitalia 

 are on the plan of moselyi, but the lateral processes of the superior 

 plate are very short and stubby ; the titillators are very heavy toward 

 base, and the tip is more strongly curved than in moselyi/ the penis 

 is fairly large, and near lower tip is a pair of rather long spines (not 

 noticed in moselyi; the inferior appendages are not so long as in 

 moselyi. 



In the hindwings the little cell at end of subcosta and radius is 

 complete, as in other small species. Front and mid legs heavily 

 banded with black on tibiae and tarsi. The eyes of male are large 

 and crowd the antennae, proportionally larger than in moselyi; the 

 antennae have the dark mark at tip of each joint so extended as to 

 give the appearance of a spiral marking. It was described from 

 Hanjang, Hupei Province, east of Szecliwan. 



A female from Kuansliien is of the same size and appearance and 

 may belong to this species. 



Three other species are recorded from Szechwan or from nearby 

 districts. These species are based on females ; /S. maxima Martynov 

 from Szechwan is said to have an expanse of 65 mm. ; the only one I 

 have seen that is as large is /^. grahami, and quite possibly it is that 

 species. 



S. cinerea Navas lias forewings 21 mm. and S. tihefana Naviis 25 

 mm. The size would fit any of the four small species; Navas gives 

 a figure of anal area of f orewing with a mark I have not seen on any 

 of my specimens; S. cinerea may be laminata, as the other species 

 are too dark to be called ^''cinereay 



Genus POLYMORPHANISUS Walker 



POLYMORPHANISUS UNIPUNCTUS, new species 



Pale greenish or yellowish, antennae black beyond base, legs pale, 

 unmarked, fringe of midlegs blackish, abdomen dull black, mesoscu- 

 tellum with a large black spot in front part. Forewings rather 

 broad, the discal cell is short, not one-half as long as the pedicel, fork
