Orthoplera in the British Museum, 135 
(in the female cotype it is thick, distinctly transverse, with slight 
double impression, with lateral margins very thick). Eyes large, 
prominent. Antennae reaching beyond hind margin of pronotum, 
markedly dilated in the middle. Pronotum rugosely punctured, 
with lateral carinae scarcely perceptible in prozona and entirely 
lacking in metazona; median carina slightly raised, shining; hind 
margin very widely rounded, nearly straight; lateral lobes strongly 
impressedly punctate, with lower margin widely rounded. Pro- 
sternal tubercle nearly cylindrical, only slightly compressed from 
behind with obtuse apex. Elytra narrow. Hind femora short and 
thick, Hind tibiae with 10 spines inwardly and 11 outwardly. 
Supra-anal plate lancet-shaped with the apex attenuate, with two 
lateral emarginations, slightly impressed, with short basal median 
sulcus. Cerci longer than supra-anal plate, wide, compressed, with 
apical half strongly flattened and bent downwards; apex sub- 
acuminate. Subgenital plate short, globose. 
General coloration (the specimen is rather discoloured and dirty) 
is dull brown. Face pale, with cheeks behind the black infra-ocular 
sulci blackish; eyes pale. Pronotum unicolorous dull brown. 
Elytra hyaline (in living specimens greenish?), with numerous 
square brown spots; anal area unicolorous brownish. Wings bluish 
with their apex slightly infumate. Hind femora reddish, with 
indistinct dark transverse bands; one yellow ring before the black 
knee. Hind tibiae greenish-brown, with brown base, yellow basal 
ring and another less defined light-coloured ring in the middle; 
spines with brown tips. Length of body (3 type) 22 mm.; 
pronotum 4°5 mm.; elytra 14°5 mm.; hind femora 15 mm. 
The female cotype differs from the male in having hind 
femora brownish, with more conspicuous oblique transverse 
bands; I believe that the reddish colour of femora in the 
male specimen is abnormal. .

Genus TyLotropipius Br, Watt. 
The systematics of the species of this genus are in a 
hopeless state, since nobody has re-examined Stil’s and 
Thunberg’s types of the genotypic species (didymus Thunb.), 
and the descriptions given by the authors quoted are not 
satisfactory. The short revision of species given lately 
by A. v. Schulthess is also of very little use, since he has 
not seen typical specimens, and, in consequence, his
