96 THE CANADIAN ENTOMOLOGIST 



Prothorax dark orange, beset with long fuscous hairs. Meso- 

 and metathorax black or fuscous black. Legs blackish, with 

 many black spines; spurs black. 



Fore-wing broad, semi-hyaline, nearly uniformly smoky 

 brown, somewhat suffused with yellowish in basal area; venation 

 fuscous; discal cell very long, twice the length of the first apical 

 cell. Hind-wing similar to the fore-wing, but the basal area not 

 suffused with yellow; colour of the wing lightened in inner marginal 

 area; venation darkish. 



Abdomen dark brown, ochraceous toward apex; hind margin 

 of each segment narrowly variegated with dark yellow. In the 

 male the posterior margin of the 9th abdominal segment produced 

 into a quadrangular prolongation in the middle; superior appen- 

 dage ochraceous, stout, and broad; inferior appendage very long, 

 stout, with the apex furnished with numerous spiny hairs; viewed 

 from above, between the inferior appendages, are seen two slender 

 yellowish processes. 



Length of body 5 — 5.5 mm.; length of fore-wing 9 mm.; length 

 of hind-wing 7 mm. 



The type is a single male specimen captured by Mr. S. Yama- 

 mura at Minakuchi, Prov. Ohmi, on November 4, 191L 



This species is closely allied to N. riificollis, but can at once 

 be distinguished from the latter by the much smaller size. The 

 structure of the male genitalia and a certain character in wing 

 venation also afford unmistakable distinctive criteria between the 

 two species.
