upwards and forwards and tapering to a point. Immediately 

 behind this the thoracic margin is deej)ly excised, and between 

 the wing-like processes and the dorsal hump are deep and 

 very rugose excavations. In the female the lateral processes 

 are very slightly and the dorsal hump rather more strongly 

 indicated. In other respects the sexes are alike. The elytra 

 are highly polished, with feebly punctured stri;x3, and the 

 })ygidium is thinly and shallowly but uniformly punctured. 



Catharsius peregrinus, llarolJ. 



We have received this very peculiar species from Bihe and 

 S;in Salvador. It is remarkable for its depressed form, 

 elongate clypeus, and the proportionately small developuient 

 of its hind body. 



Gymnopleurus azureus, Fabr. 



Specimens from Bihe, agreeing with the description of 

 G. olivaceus, Qued., seem to belong to this widely distributed 

 Fabrician species. G. insidiosuSj Pering., is, I believe, also 

 inseparable from it. 



Copturrhiiia angolensiSj sp. n. 



Nigra, opaca, sat convcxa, capite crebre rugose, clypoo bideutato, 

 dentibus paulo produclis ; prothorace crebre puuctato-rugoso, 

 postice elevato, parte elevata leviter 4-aeuminata, lateribus sub- 

 tiliter marginatis, regulariter arcuatis, autice paulo divergentibus ; 

 elytris dense punctatis, subtilissiine striatis, lateribus pone 

 humeros sinuatis.

This species is very closely related to 6'. auspicata^ Pering., 

 with which it almost exactly agrees in size, sculpture, and 

 general form. The prothorax, however, is slightly different 

 in shape. In the male of C. auspicata it is broadest behind, 

 the sides slightly approximating anteriorly in a sinuous line. 

 In the new species, on the contrary, there is a slight widening 

 towards the front and the sides are uniformly curved. The 

 raised margin is extremely narrow, and not, as in the other 

 species, widened at its posterior part. The dorsal elevation 

 does not extend quite so far forward, and exhibits four angu- 

 lations, the slight outer ones being entirely absent in 

 C. auspicata. This difference is traceable also in the females.
