These specimens are small for the species, the males with 
forceps rather slender and with the usual meso-distal tooth very 
small.

These specimens agree fully with the type, except in having the 
exposed portion of the wings immaculate and but a single 
disto-median internal tooth on each arm of the forceps. These 
features are attributable entirely to individual variation. Length 
of body, 9 and 11.6; of forceps 7.1 and 7.3 mm. 
After comparison of this species, chosen as genotype of Vlax 
by Burr, with perditus, chosen as genotype of Praos by the same 
author, we are astonished to find that his generic description of 
Vlax is evidently drawn from other species there included and 
that the selected genotypes of these two genera are clearly con-
