antennis ((?) corpore phis sesqui-longioribus, articulis quinque 

 primis scabrosis, ( J ) corpore vix brevioribiis. Long. 11 — 13 mm. 



Hah. Nyassa. 



Almost wholly of a dull steel blue colour, with the antennae 

 inclined to black. Prothorax very densely and finely punctulate. 

 Elytra rugosely punctured, each with two or three very feebly 

 raised longitudinal lines, apices somewhat obliquely rounded. 



^ . With the prothorax slightly longer than broad, with a 

 scutiform subnitid space on the disk posteriorly ; with the antennae 

 more than half as long again as the body, with the first five joints 

 thicker and scabrous. Abdomen steel blue, with what appears to 

 be the last dorsal segment modified into a broad bifurcate process, 

 with a somewhat similarly shaped but smaller process, beneath it, 

 with both these processes projecting beyond the apex of the fifth 

 ventral segment. 



2 . With the prothorax broader than long, the disk destitute of 

 a shining space. With the antennae scarcely as long as the body, 

 with the scape scabrous, the four following joints somewhat 

 asperately punctured. Abdomen underneath fulvous brown, with 

 the apex of the last segment steel blue. 



In this species the scape of the antennae is provided at 

 the apex with a sharp carina, limiting a smooth ter- 

 minal groove, but it is not produced into a spinous or 

 angulate process on the inner side, as is the case with 

 the majority of the species of the genus.

Hah. Nyassa? and Natal. 



Reddish testaceous, with a faint tawny ochreous pubescence. 

 Prothorax briefly and sharply enough spined on the middle of each 

 side; the disk with a callosity in the middle, and with two small 

 and very feebly raised tubercles anteriorly. Elytra closely punc- 

 tured, conjointly rounded at the apex. Legs testaceous, with the 

 extreme apical border of the femora blackish. Antennae wholly 

 reddish testaceous. Each of the first four abdominal segments {S^) 

 with a large transverse tomentose depression. 



The prosternal process has, in the present species, a 

 form unlike that of any Cerambycid known to me. This
