30 Mr. F. P. Pascoe on some new or little-hnown 



Erythrus ? Bowringii. 



E. ? angustatus, riibro-sericeiis ; prothorace ovato, medio carinato ; elytris 

 elongatis, apice trimcatis ; corpore infra nigro, griseo-piibescente. 



Hah. Hong Kong. 



Narrow and elongate, brick-red, covered witli a fine silky pubes- 

 cence ; head roughly punctured, th^ muzzle rather short; antennae 

 black, longer than the body in the male, about three-quarters of its 

 length in the female^ the serration beginning with the fourth joint ; 

 prothorax ovate, a long linear carina in the middle, two black spots 

 anteriorly on the disk, marking the nearly obsolete tubercles ] scutellum 

 triangular ; elytra elongate, scarcely wider than the piothorax, the sides 

 incurved and expanding very slightly posteriorly, the apex truncate, a 

 broadly elevated line extending from the shoulder to near the apex ; 

 body beneath black, closely covered with a short grejdsh-white pubes- 

 cence ; legs black, slightly pubescent, femora of the intermediate pair 

 produced beneath, and fringed at the deepest part of the border with 

 short stiff hairs. Length {S) 9, ( $ ) 11 lines. 



This species rather breaks in upon the homogeneity of Erythrus, 

 but T scarcely see sufficient characters to warrant its separation as a 

 distinct genus. The narrow form, the ovate prothorax, and the 

 serrated portion of the antennae beginning at the fourth joint instead 

 of the fifth, seem to be the most distinctive points. The muzzle is 

 also somewhat shorter and the palpi longer, but I think it would be 

 difficult to formulate a satisfactory diagnosis on these. The pecu- 

 liarity of the intermediate femora is less marked in the female. I 

 am indebted for this and the two preceding species, and indeed for 

 many others, to John Bowring, Esq.

Hah. Natal. 



Dull black ; head coarsely punctured, with a few scattered j^ellowish 

 hairs ; epistome very short, lip narrow, bordered \\dth stifl' yellowish 

 hairs ; prothorax short, subcylindrical, slightly narrowed behind, closely 

 and coarsely punctured, and covered with a golden-yellow pile ; scu- 

 tellum acutely triangidar ; elytra very finely and closely punctiu-ed, 

 sparsely pubescent, luteous yellow, a black band near the base, a second 

 at the middle, and a third towards the apex, but which does not attain 

 to the suture ; body beneath black, more or less covered with a silvery- 

 grey pile, the last abdominal segment extending beyond the elytra ; 

 legs black, more or less pubescent ; femora scarcely clavate, the posterior
