anterior edge ; cheeks, partly, and subajiical and basal belts of pnniotum the same 

 colour. Greyish greeu tometitnra of elytra here and there dotted with ochraceons 

 bntf : three conspicuous spots of this colour on each elytrum — one at basal fifth, the 

 second larger, median, obliquely transverse, the third at apical fifth, longitudinal 

 and generally accomjianied laterally by a fourth spot, with which it is often fused 

 together ; the third spot constricted in middle. Sides of sterna and large lateral 

 spots of abdominal segments 1 to 4 ochraceous buff. 



Length, 18 — 22 mm.; elytra, 12 — 15 mm.; breadth, 5J— .s mm.

Four c? c? and three ? ? . 



65. Bangalaia vittata spec. uov. 



c?. Black, tomentum greyish white, slightly yellow on underside. Cheek, 

 a broad mesial vitta on occiput and pronotnm, scutellnm, a broad discal vitta on 

 each elytrum extending from base to apex, ill-defined, and the under surface, excejit 

 middle, greyish or yellowish white ; frons and legs covered with a thin grey 

 pubescence. E3'e as in the two preceding species, but lower lobe more rounded. 

 iScape of antenna less than half as long again as broad, fourth segment little 

 shorter than third, segments 3 to 5 rather strongly fringed beneath. Occiput 

 smooth, except some granules near interautennal groove. Pronotnm without trace 

 of side-spine, as long as broad, widest before basal constriction, smooth, with very 

 few punctures laterally, sides almost straight, base mesially widened and laterally 

 sinuate. Elytra narrow, convex, parallel from base to apical fourth, almost evenly 

 punctured all over ; shoulder peculiar, not projecting, but on the contrary slanting 

 backwards, the angle being very obtuse ; apex of elytrum rounded. Prosterual 

 process curved, not tuberculate. Carinae of tibiae not so distinct as in the other 

 species. 



Length, 15 — 17 mm.; elytra, 10 — 11 ram.; breadth, 4 — 5 mm.

Two (?c?. 



In ajipearance similar to Acridocephala nicoleti. 



66. Pinacostema mimica spec. nov. 



c? ? . Li colour and markings almost exactly the same as green specimens of 

 Sternotomis regalis. Narrower than this species, agreeing in shape and structure 

 with the other three species of Finacosferiia {mcchoici, nachttgali, tcei/munni), 

 elytra less densely and more finely punctured. Pronotnm with indistinct green 

 transverse belts on the disc, and with a rather feeble but distinct transverse groove 

 before middle ; an ochraceous orange transverse ovate spot in front of the lateral 

 tubercle. Elytra with three spots of the same colour placed as in Sternotomis 

 regalis, but the shoulder spot smaller, rounded. 



Length, 17 mm.; elytra, 12 mm.; breadth, Qh mm.

67. Pinacosterna smithi spec nov. 



S- Like tnimica, but prothorax witliont antemedian transverse groove, lateral 

 spot much larger, extending to apical margin, not sharply defined ; no humeral
