130 Dr. B. P. Uvarov’s Notes on the 
with apex truncate and slightly bituberculate at the front side. 
Mesosternal lobes transverse with interspace quadrate. Meta- 
sternal lobes non-contiguous. Elytra short, reaching to about the 
middle of abdomen. Wings coloured with apex dark. Abdomen 
(3) with apex strongly recurved and inflated; anal segment very 
large; supra-anal plate large, oblong, gradually narrowed towards 
the apex, sulcate in basal half, low incrassate margins of the sulcus 
strongly diverging beyond its middle. Cerci, as in T'hisoicetrus, 
strongly compressed, especially in the apical part, where they are 
bent downwards, with apex widely rounded. Subgenital plate 
very short, globose. Hind femora rather slender. Hind tibiae 
with nine outer and nine inner spines. Hind tarsi as in T'hisoicetrus. 
Genotype: Thisoicetrellus recurvus, sp. 0. 
This genus strongly resembles Thisoicetrus in all its 
characters, but is distinguished by the extraordinarily 
recurved and inflated apex to the abdomen, the shortness 
of the elytra and the form of the prosternal tubercle. 
1. Thisoicetrellus recurvus, sp. n. 
¢g. Blackish olivaceous, with yellowish-green and black design. 
Antennae pale brownish. Face pale; frontal ridge olivaceous 
with blackish points; sides of the head behind the infraocular sulci 
black; vertex brownish, with not sharply defined blackish median 
stripe included between two lateral yellowish-green stripes. Prono- 
tum with wide median stripe which is castaneous in its middle and 
blacker towards the margins; lateral stripes narrow, greenish- 
yellow; lateral lobes blackish olivaceous. Elytra brownish 
olivaceous, except yellowish-green anal field. Wings yellowish 
with fore margin infumate towards the apex. Sternum and abdomen 
olivaceous. Cerci dark brown with apical part light brown. Hind 
femora outwardly and inwardly reddish in basal half with an indis- 
tinct dark band in the middle, yellow in apical half with an ill-defined 
dark transverse band before the black knee; the lower sulcus 
sanguineous. Hind tibiae black, with orange ring near the base; 
spines white with black tips. Hind tarsi brown. 
Length of body (i.e. from the fastigium of vertex to the apex 
of subgenital plate in normal recurved condition of abdomen) 
17 mm.; of pronotum 4 mm.; of elytra 6 mm.; of hind femora 
12-5 mm.
