Coleoptera from East Africa. 49 



bisinuate at the basal margin, somewhat produced and 

 rounded in the middle at the anterior margin. Prosternal 

 process rather narrow, nearly vertical in front, thence gradually 

 sloping and expanding behind. Mesosternal process with a 

 small tubercle at about the middle of its length. Middle 

 tibiEB with an oblique groove on the outer edge. Claws of 

 tarsi divergent. Antennse with a short fringe of hairs under- 

 neath, about twice as long as the body in the male ; the 

 scape stout, with an open cicatrix at the apex ; third joint 

 longer than the first and shorter than the fourth, fourth to 

 sixth subequal or slightly increasing in length, seventh to 

 tenth gradually shortening; third joint thickened in the 

 female. 



This genus seems best placed in Lacordaire's group Proso- 

 pocerides, though the head cannot, as in the definition of that 

 group, be described as " broadly but moderately concave 

 between the antennary tubercles, with the latter short," &c., 

 for the head is, in fact, strongly concave between the promi- 

 nent and diverging antennary tubercles. 



Protomocerus Gregorii, sp. n, 



Pube albido-einerascente vestitus ; capita, anteunis, prothoracis 

 plaga magna laterali utrinque, at elytrorum humeris subfuscis ; 

 alytris fasciculis brevibus fulvis sat dense oraatis ; pedibus 

 brunneo cauoque variagatis, tarsis supra griseis.

General pubescence of an ashy-white colour. On the head, 

 the antenREe, the shoulders of the elytra, and over a large area 

 on each side of the prothorax, as well as spots on the legs, 

 especially of the two hinder pairs, the pubescence is some- 

 what dark brown or fulvous brown in colour, while numerous 

 small tufts of fulvous hairs are scattered over the elytra. 

 The ashy-white area on the disk of the pronotum between 

 the lateral brown areas is in the form of a triangle, with its 

 apex in front and marked by a small elevation ; small 

 granular elevations are scattered over the central part of the 

 disk. The prothorax is marked on each side anteriorly with 

 an oblique groove, which, commencing at the side of the 

 median elevation, curves slightly backwards and then out- 

 wards between the two anterior tubercles on the side. 



In the male the frontal process projects downwards and is 

 curved slightly forwards at the extremity ; it is concave in 

 front and is covered with tawny hairs except along the median 

 line.
