Cetoniidae. 

 Gonochilus nigerrim.U8. 



Entirely black and shining. Head distinctly punctured, 

 the punctures moderately close together, but not crowded. 

 Thorax distinctly punctured, the punctures widely separated 

 on the back part of the disk, rather close together near the 

 front angles ; the deflexed anterior lateral margin is densely 

 obliquely striolate. Scutellum very acuminate, with very 

 few punctures. Elytra impressed at the suture, rather finely 

 punctured, the punctures separated from each other by three 

 to four diameters of a puncture. The margins behind the 

 middle are transversely finely striolate, the striola) extending 

 on the margin nearly to the humeral enlargement. 



This species closely resembles a species which I b dieve is 

 G. rujiventris, but differs in being entirely black or with only 

 the faintest tinge of brown on the pygidium. The punctua- 

 tion of the thorax is much closer. The punctures on the 

 disk of the elytra are much closer, and the transverse ruga? on 

 the sides extend nearer to the humeral enlargement. The 

 clypeus is slightly narrowed in front. 



Length 9 lines. 



TrichiidaB. 



Calemetopus Rollisii, sp. n. 



Black, rather narrow, depressed, pubescent. Head quad- 

 rangular in front, very slightly concave, finely and closely 

 punctured, with sparse white pubescence; anterior margin 

 rather strongly emarginate, with the angles rounded. Eyes 

 very prominent. Antennae with the club very long. Thorax 

 at its widest part a trifle broader than the head, slightly 

 narrowed in front and towards the base, broadest in front of 

 the middle ; clothed above with reddish-brown pubescence, 

 with a little black on the anterior margin and near the front 

 angle, with a streak of white scale-like hairs down the middle, 



and with four small white spots on each side, placed • • . 

 Scutellum elongate-triangular, clothed with white scales. 

 Elytra flat on the back, with the sides abruptly deflexed, 

 considerably broader than the thorax, somewhat narrowed 

 towards the apex, dull, obscure yellow, with the suture and 

 margins black, the black on the suture a little dilated below 

 the scutellum ; the deflexed margins are black, with a yellow 

 mark below the shoulder. Each elytron has several lines of 

 black punctures. The pygidium is very prominent, conical,
