Orthoptera in the British Museum. 141 
from the description of C. somalicus, but this drawing is 
still more unlike the specimen from which it was made. 
In general habitus C. somalicus is very like C. oberthiiri 
Bol., but it differs markedly in the shape of the male sub- 
genital plate, which in C. somalicus is not bent upwards, 
as in all other species, but horizontal, as may be clearly 
seen in Burr’s drawing. ‘The prosternal tubercle in 
C. somalicus is strongly compressed from in front and 
behind, in front view quadrate with very slightly emargin- 
ated apex, in profile narrow, a little swollen in the middle 
with slightly narrowed apex; it is rather like the shape 
of tubercle in C. oberthiiri, but in the latter species the 
tubercle appears in frontal view with strongly rounded 
apical edges and by no means quadrate.

Sokotra, 1 9, 1 larva 9. 
5, Cataloipus abyssinicus, sp. n. 
Size a little larger than in C. oberthiiri Bol., but smaller than in 
C. cymbiferus Krauss. General colour greenish-yellow, head and 
pronotum with the usual brown longitudinal stripe in this genus. 
Frontal ridge gradually narrowed towards the fastigium, with 
middle and two lateral longitudinal stripes of bluish-grey colour. 
Pronotum with straight, diverging backwards lateral carinae, 
disappearing in metazona; lateral lobes bluish-grey, with four 
subquadrate yellowish spots in the middle and with the fore upper 
edge blackish, this coloration prolonged narrowly along the lateral 
carinae (up to third transverse sulcus) and. along the fore margin. 
Prosternal tubercle nearly cylindrical, very slightly impressed 
behind, not narrowed towards the apex, obtuse, directed slightly 
backwards. Space between the mesosternal lobes nearly twice as 
long as broad. Elytra yellowish with brown veins, with greenish 
stripes in scapular and axillar fields, without any spots or points; 
they reach the apex of abdomen, but not hind knees. Hind femora 
with very slightly darkened upper keel of area externomedia; 
knees blackish with pale lobes. Hind tibiae greyish-blue with pale 
ring near the basis. Supra-anal plate bluish, with short attenuate 
apex and short sulcus at the base. Cerci compressed, especially in 
the apical third, where they are far broader than at their base and 
strongly bent downwards. Subgenital plate large, erected with a 
short angular emargination at the apex. 
Dimensions of the typical male are: Length of the body 38 mm. ; 
of pronotum 6-5 mm.; of elytra 27 mm.; of hind femora 27 mm.
