128 Dr. B. P. Uvarov’s Notes on the 
black fascia, widening posteriorly. Pronotum with metazona nearly 
twice as short as prozona; prozona slightly tectiform, metazona 
flat; lateral carinae straight, parallel, in metazona obliterate ; 
median carina raised, acute; disk with a black parallel longitudinal 
fascia and two greenish-yellow lateral bands; lateral lobes coriaceous, 
totally black. Prosternal tubercle compressed from fore and hind 
side, with obtuse rotundate apex. Elytra dark brown, except 
green anal area, reaching the apex of the abdomen, with straightly 
truncate apex. Wings totally infumated. Fore and middle legs 
olivaceous. Hind femora with the basal half outwardly olivaceous, 
becoming black towards the middle, in the apical half with two 
yellow transverse bands, divided by a black one; the knee totally 
black; inner side of femora yellowish-green with two black trans- 
verse bands and black apex. Hind tibiae with black base, followed 
by a yellow ring, which is delimitated by another, less defined black 
ring; the apical half and tarsi sanguineous. Anal segment (<3) 
with two short widely standing processi. Supra-anal plate rotundate 
triangular with the apex subacute, with a short and rather wide 
longitudinal sulcus at its base. Cerci longer than supra-anal plate, 
compressed, beyond the middle widened and rather suddenly 
_decurved, with rounded apex. Subgenital plate with its apex 
attenuate vertically, obtuse and bearing two very low tubercles. 
Length of the body (3 type) 22 mm.; of pronotum 4-5 mm.; of 
elytra 13°5mm.; of hind femora 15 mm, 
The prominent head, the shape of pronotum, shortness 
and form of the apex of elytra, and, especially, the peculiar 
form of the subgenital plate are the chief characters of this 
remarkable species, which is unfortunately represented by 
one male specimen only. 
British Museum specimen: Fwambo, British Central 
Africa (A. Carson), 1 3 (type). 
There is in the Museum collection another species (from 
Nyasaland), the male of which is also very attenuate at 
the apex of the subgenital plate, without two tubercles 
on it, which is doubtless new, but I abstain from describing 
it, since it is represented by two (gj and Q) very badly pre- 
served specimens, almost totally decolorated by alcohol. 
venus THISOICETRINUS, g. n. 
Thisoicetrus dorsatus F.-W., differs from all other species 
of the genus Thisoicetrus in having the antennae very long, 
the pronotum strongly rounded without any trace of lateral 
carinae and the male subgenital plate, not short and obtuse,
