lateraliter obtuse tuberculato, supra insequali, haud plicato ; 

 antennis ( <$ ) quam corpore vix brevioribus. 

 Long. 38, lat. 11 mm. 



Hab. Somali. 



Closely resembles T. Klugii, Lac., especially in the charac- 

 ter of the elytral pubescence, which exhibits a much ruffled 

 or somewhat wavy appearance. It is distinguished from 

 Klugii by its shorter antennas, those of the male scarcely 

 reaching to the apex of the elytra, and by the character of the 

 prothorax, the disk of which is not transversely wrinkled, but 

 owes its unevenness to a number of slightly raised areas, of 

 which one is submedian in position, the others placed more 

 laterally; the prothorax is somewhat swollen on each side, 

 where it presents two minor protuberances, one nearly median 

 in position, the other lying between the middle and the ante- 

 rior margin. 



The presternum is strongly arched, and bears near the 

 middle of its posterior face a small somewhat laterally com- 

 pressed tubercle. 



Idactus maculicomis, Gahan. 



A male example of this species was taken by Mr. Green- 

 field. It differs from the described female type as follows : — ■ 

 Antennas more than half as long again as the body. Last 

 ventral segment of abdomen much shorter and without a 

 median impressed line. Besides this difference in structure 

 there is a slight disagreement in the markings. In the Somali 

 specimen there is a pale brown patch, partly surrounded by 

 a distinct white line, placed obliquely near the middle of each 

 elytron. In the female type there is a dark brown patch 

 under each shoulder not present in the second example. This 

 specimen may therefore belong to a distinct local variety.
