UMTATA, u. gen. 



Allied to Arytropteris, but the fastigium is narrower and more 

 acute, and the shape of the pronotum, as well as the prominent 

 membranous elytra which the pronotum cannot effectually conceal, 

 distinguish at once the male from the similar sex of Arytropteris. It 

 should be noted, however, that in some of the species belonging to the 

 second group of the last-named genus, the elytra are slightly visible 

 near the apical part of the pronotum. The fore tibiae are as in 

 Arytropteris, that is to say, they have no apical spine on the outer 

 or inner margin, and bear two spines each, the first situated near the 

 auditory cavity, the other at the second third of the length ; anal 

 segments, cerci, and sub-genital lamina of the same type as those of 

 Arytropteris. 



UMTATA MUSICTJS, n. sp. 

 (PI. XLII, fig. 6.) 



$ . Straw-colour, shiny, head smooth, frontal part quite vertical 

 and dotted on the frous and clypeus with a few very short stiff 

 bristles ; prouotum sub-cariuate on each side of the disk for about 

 half its length with the sides depressed for the same distance, but 

 sub-plane from the centre to the apex, the posterior part being oblong, 

 and therefore very little attenuated, the lateral depression is closely 

 granulate, the outer margin is vaguely serrulate along the depression, 

 but the remaining part is smooth ; the membranaceous elytra are very 

 convex, and so developed as not to permit of the prouotum covering 

 the abdomen, which is only slightly shorter than the former. Legs 

 long, posterior femora broadly dilated at the base, spines of all the 

 tibiae strong ; the spines of the coxae very conspicuous ; anterior 

 tibiae with two well-developed spines, one near the auditory groove, 

 the other situated at two-thirds of the length ; the disposition of the 

 spines on the intermediate tibiae is 2-3 ; both fore and middle femora 

 have four spines underneath, and there are two rows, of eight and nine 

 respectively, under the posterior ; supra-anal lamina truncate, the 

 angles sharply acuminate, styles short, thick, curving inwards, sub- 

 genital lamina triangularly scooped at apex, and tri-cariuate under- 

 neath ; cerci short, sub-cylindrical. 



Length of body 28 mm. ; of pronotum 18 mm. ; of hind femur 

 30 mm. ; of hind tibia 28 mm.
