NEUROPTEROID INSECTS PROM SZECHWAN — BANKS 185 



is just behind origin of first radial sector, the first branch of cubitus 

 arises much beyond forking of medius; the cross vein from medius 

 to radius is a short distance out on the first radial sector, and is 

 hyaline; the medius at the cross vein to cubitus is scarcely bent, so 

 that the cross vein is almost as long as that from cubitus to anal 

 vein: about six inner gradates, and seven or eight outer ones, the 

 most posterior of inner series is plainly beyond the nest. 



Male appendages slender, inner edge with an erect, slender spine 

 beyond middle, but about twice its length before the tip. 



Length of f orewing, 9 mm. ; -width, 3 mm. 



From Tsi King 13,000 feet, August 11, one male, holotype, U. S. 

 X. M. Xo. 53115. A female from near TVashan, 6.000 feet, July 26, 

 probably belongs here, venation about the same, but the anteimae 

 are wholly pale. This species is related to H. poppei Petersen, which 

 Tjeder records from Kansu. H. poppei is said to have pale antennae, 

 darker at tip. Their figures show the spine heavier and nearer to 

 the tip. Petersen speaks of the cylindrical hindtibiae. There are. 

 however, differences in their figures, and there may be two species. 

 The basal venation is much as in E. pini and H. nitidulus for which 

 Kriiger makes Reuterohius and Schneideroiki-s, and it may be these 

 form a subgenus. 



HE3IER0B1US GRAHAMl, new species 



Face shining, very dark brown, cheeks also, vertex very dark, last 

 joint of palpi dark, antennae brown on outer side and above of basal 

 joint, below pale, other joints pale, with broad rings or brown at tips : 

 pronotum very dark brown, a pale median line, a little widened be- 

 hind, rest of thorax above also dark brown, no pale spots, except 

 faintly in middle front of mesouotum, hair on thorax very long; 

 abdomen also dark brown above and below. Forewings rather 

 heavily marked with brown; cross veins brown, longitudinal veins 

 mostly brown, with short hyaline spots, the brown extended each side 

 on membrane, larger brown spots along median and cubitus, over the 

 first and last connecting veins, and halfway along over the second 

 and third branches of the cubitus: margin of wing faintly, but 

 broadly, infuscate, a few hyaline spots along outer and hind margin, 

 but much separated, stigma not especially marked ; in hindwings veins 

 mostly brown, stigma more prominent. 



"Wings rather long, apex rounded, cross vein from radius to median 

 is near base, three radial sectors, equally separated, third forked 

 three times ; first cross vein back to radius farther than usual beyond 

 second fork ; seven inner gradates, last two close together, but last is 

 a little beyond tlie other; seven outer gradates, rather widely 

 separate: in hindwing five gradates in outer and two m inner row.
