126 DESCRIPTION OF NEW COLEOPTERA, 



is the S. Sumatreusis, Westw. ; which Sir Starafbrd Raffles ob- 

 served to be also fouud on dead animals. 



41. — C(EL0DK3 BIMACULATUS. 



Niger nitidup, capite punctate, thorace subla^vi marginibus 

 confertini puuctulatis piceis, elytris biseriatim punctatis 

 macula humerali rubra. 



Habitat in stercore humano. 



Long. 3 lin., lat. 2 lin. 

 The upper surface is of a glossy black inclining to pitchy on 

 the lateral margins of the thorax. The head is thickly punctured. 

 The thorax is almost free from punctures in the middle, but the 

 lateral margins are densely and finely punctured. The scutellum 

 is punctured at the base and has a longitudinal impi'ession to- 

 wards the apex. The elytra have four double rows of small 

 punctui'es besides a single one at the suture and sides. On each 

 humeral callosity there is a small dark red indistinct spot. The 

 under surface and legs are of a pitchy hue, the latter being 

 slightly ciliated. 



This species so closely resembles the insects of South America 

 placed by Westwood in his genus Ccelodes, that I have, though 

 with some doubt, referred it to that genus. I can find no evidence 

 however of the sexual differences which he speaks of, viz. — the 

 excavated thorax and dentated ungues of the male. In this 

 species also the labrum is truncate, and without the punctured 

 margin of Ccelodes ; the mentum also is more emarginate than in 

 that genus. 



42. — BOLBOCERAS RHINOCEROS. 



Cervinus nitidus, thorace fovea utrinque impresso, elytris 



punctato-striatis, corpore subtus hirsuto. 

 Mas. capitis cornu valde producto subincui'vo, thorace autice 



bicornuto medio retuso lateribus punctulatis. 

 Fem. capitis medio transversim carinato, carina utrinque furcata, 



occipite bituberculato, thorace antice retuso subUevi medio 



punctulato postice lt«vi. 

 Long". 8 lin., lat 5 lin.
