short, outer margins slightly concave; prominent lobes on inner 
margin of forceps near the base; hypovalvse short, uniting near 
the middle of the genital bulb, and extending slightly beyond 
the base of the forceps; ventral valves simple, each consisting 
of a slightly flattened process, with a few short barbs on inner 
surface distally, and terminating in a longer series of barbs 
directed inwards; preeiproct much narrowed distally, with a 
pair of broad terminal lobes, close together. 9 : internal skel- 
etal plate of ninth segment large, with two long, slender distal 
processes and a pair of large, ear-like flaps laterally; the usual 
axis is short, but there is a very slender median process extend- 
ing posteriorly.

This strikingly marked species is easily recognized by the 
oblique stripe traversing the middle of the wing, and extending 
posteriorly and distally from the anterior margin. The short 
hypovalvae of the male genital bulb are unique among the known 
Chinese species of Panorpa , but are very much like those of 
certain Japanese and Siberian species ( e.g ., P. wormaldi MacL., 
preyeri MacL., etc.) to which obliqua is undoubtedly closely 
related. Certain North American species of Panorpa (e.g., 
lugubris Swed., nuptialis Gerst., rufa Gray) have similar hypo- 
valvae, but their other genital structures are very different from 
those of obliqua and the other Asiatic species indicated.

This species was based on a single male from Kuling, Kiangsi 
Province, and deposited in the Musee Heude, Shanghai. In the 
Museum of Comparative Zoology there are four males and five 
females which I consider to be this species. Four of these (13, 
3 $ ) were collected in Taipingshien, Anhwei Province, China, 
October 1932 (G. Liu); and the others on Huang Shan, in
