I have not seen this species, but it appears to me to 
belong to another genus.

I cannot agree with Bolivar, who placed this species 
among Thisoicetrus, while it has short, narrow and acute 
cercl. It is true that the number of outer spines on the 
hind tibiae (11-12) is rather high for an Huprepocnenus, 
but the same number is to be seen in EH. calceata Serv. 
E. hokutensis seems to be rather closely related to EH. 
plorans Charp. (not plorans of Shiraki, which is a distinct 
species, described by Bolivar as EH. shirakii), but distin- 
guished by a long pronotum, the coloration of the hind 
tibiae and the number of their spines.

This is an extremely well-marked species, the chief 
character being the peculiar shape of the male cerci, which 
are not short and acute, as in other species of this genus, 
but are far longer than the anal plate, and have a dilated 
apex. The affinity of this species to E. alacris is shown 
by the absence of a median carinula on the vertex. 
The specimens from China and Baltistan differ from 
Japanese examples by their smaller size; it is possible
