218 PROCEEDINGS OF THE NATIONAL MUSEUM vol. S8 



From 9 miles southwest of Tatsienlu, June 23-27, 8,500 to 13,000 

 feet (holotype) ; 30 miles north of Tatsienlu, July 9-19, 1,200 feet; 

 near Moupin, July 22-24; Wei Chow, 65 miles north of Chengtu, 

 August 15, 9,000 to 12,500 feet (all in Szechuan) . Holotype, U.S.N.M. 

 No. 53172. Paratypes in U.S.N.M. and M.C.Z. 



Although this species, as far as genitalia are concerned, agrees 

 better with Pseudostenophylax, I place it near Trichophylax^ since 

 it has no specialized hairs or scales on the hindwings, and the hairs 

 above on abdomen are y&ry much longer than I have seen on any 

 other limnephilid. These hairs, however, are not so long as Mosely 

 figures for the genotype; it differs in the genitalia, in longer first 

 apical fork, in the male palpi, etc. 



This is very close to Psevdostenophylax hirsutus Forsslund from 

 Kansu Province. His figure shows the terminal pieces of the penis 

 sheath shorter and bent, and the lower appendages, although tri- 

 angular, are not so long as in monticola. His name hirsutus would 

 be very apt, but he does not say the hair is longer than usual, only 

 that it is quite dense or thick. 



Genus HALESINUS Ulmer 



HALESINUS FENESTRATUS, new species 



Plate 29, Figure 53 



Black ; clothed mostly with black hair, some yellow on face, vertex 

 and mesonotum with numerous black hairs with yellow tif)s; tarsi 

 black, femora and tibiae more or less pale brownish, hind tibiae espe- 

 cially pale. Forewings dark brown to nearly black; costal area 

 with transverse pale marks much like H. tenuicomis; in anal area 

 two oblique white marks, nearly parallel, basal one usually broken 

 (in tenuicomis divergent), around outer margin with white spot in 

 each cell, and extended in white on the otherwise black fringe; a 

 few small patches of white scattered over wing, and at the anasto- 

 mosis, just before and a wide area beyond, is a large pale area, 

 clothed with white and golden hairs, the anastomosis and apical veins 

 remain dark. Hindwings gray, costal tip darker, veins dark, outer 

 fringe nearly black. 



Venation much as in tenuicomis and aWopunctatus^ but in forewing 

 the discal cell is not twice as long as its pedicel, and in hind wing 

 fork one does not extend back on the discal cell (considerably so in 

 other species). Forewings with outer margin distinctly crenulate. 



Length of forewing, 12 mm. ; width, 4 mm. 



Two females without definite locality, except Szechwan, I35OOO 

 feet, July 9-12. 



Keadily distinguished by the large pale area at anastomosis; E. 

 ussuriensis is also separated by the very long discal cell. Holotype, 

 U. S. N. M. No. 53173. Paratype ( no head) in M. C. Z.
