genus Pampsilota which easily explains Kirby’s inability to detect 
superapical spurs. 
Pampsilota nigriceps, sp. n. 
This species is probably more closely allied to sinensis (Kirby ) 
than any other described species of this genus, but it may be 
differentiated from Kirby’s species by the black legs and black 
tergites. 
Female.—Length 11 mm. Anterior margin of the clypeus 
very slightly incurved ; supraclypeal area black ; frontal fovea 
open below, extending parallel until it reaches the anterior margin 
of the anterior ocellus, with an accentuated triangular-shaped 
depression opposite the upper margin of the antennae; postocellar 
line distinctly shorter than the ocellocular line; postocellar furrow 
well defined, about the width of the posterior ocellus behind the 
posterior ocelli ; postocellar area strongly convex, slightly parted 
by a median furrow; antennae typical for the genus, extending 
to the posterior margin of the scutellum. Rufo-ferrugineous; head 
except the palpi black ; scutellum, metanotum, tergites except 
the lateral margin and the apical portion of the posterior ones, 
the sheath above, mesosternum and legs black; the anterior legs 
beneath are piceous ; wings dusky hyaline, venation black. 
Male.—Length 8 mm. What appears to be the male of this 
species has the frontal fovea closed below and differs in colour in 
having the scutum and the basal portion of the prescutum black, 
and in the piceous stigma and paler wings.
