species next following. He distinguishes it from the typical 

 A liarringtoni by the possession of a more broadly rounded 

 clypeus, without a tubercle, and two more pronounced tubercles 

 upon the frontal suture. I have seen no specimen corresponding 

 to this. 



5. Peperonota cristata, sp. nov. (Plate IV, figs. 39, 40.) 



Testaceous, with the head, scutellum, the depressed part of the 

 elytra adjoining the latter and irregularly sprinkled small spots 

 upon their lateral and posterior parts, the base of the pygidium, 

 •the front tibiae, and the tarsi black or brown. 



J . The clypeus bears a small blunt tubercle at its front edge 

 and a strongly bilobed crest on the frontal suture. The pronotum 

 is finely and sparingly punctured and only moderately convex ; its 

 front angles are acute, the sides parallel behind and the base pro- 

 duced backwards in' the middle as a narrow lobe, which is divided 

 at the end into t\\o slightly diverging lobes. The scutellum is 

 depressed and the elytra are narrowly depressed on each side of 

 it, the depression scarcely extending beyond the scutellum. The 

 depressed surfaces are very coarsely punctured and shining, and 

 the remainder of the elytra is opaque and rather feebly punc- 

 tured. In other respects the characters are the same as those of 

 the male P. liarringtoni^ to which it is very similar, although dis- 

 tinctly differing in the well-marked transverse elevation upon the 

 forehead, the minutely forked posterior process of the pronotum, 

 and the smaller depressed area of the elytra adjoining the scu- 

 tellum. The single specimen is of rather large size, but the 

 thoracic process is short, though slender (reaching only as far 

 as the apex of tlie scutellum), and it is probable that the species 

 attains a greater development. 



The female is unknown. 



Length, 22 mm. ; breadth, 13*5 mm. 



Burma : Ruby Mines ( W. Doheriy).

Genus DICAULOCEPHALUS. 



Bicaulocephalus, Gestro, Ami. Mus. Civ. Geneva, (2j v, 1888, p. 623. 



S . " Body short, broad and very convex. Head broad and 

 triangular, with the clypeus reflexed, pointed and tuberculate at 

 the apex. Mandibles strongly produced laterally and curved 

 backwards, resembling antlers pointed at the end. Eye- ridges 

 produced outwards on each side into a spine. Antennae 10- 

 jointed, with a small 3-jointed club. Pronotum nearly serai- 

 circular, strongly convex, shining, punctulated, with the posterior 

 margin rounded in the middle and sinuated on each side. 

 Scutellum broad and subtriangular. Elytra short, convex and 

 opaque, depressed near the scutellum, each with a strong basal 

 .and more feeble apical callus. Pygidium incurved. Legs short.
