208 ZOOLOGICxVL RESULTS OF THE EUWENZORI EXPEDITION. 



preceding three joints united. Head closely punctate, with a smooth, feebly raised, 

 median line extending from the clypeus to the occiput. 



Length 10 ; breadth 3 mm. 



Hah. Mokia, S.E. Ruwenzori, o-lOO ft. 



This species is apparently very nearly allied to M. atrocliahjhea Mars, from Angola, 

 and may possibly prove to be only a variety of it. 



HoRiA NiTiDA, sp. n. (Plate VT. fig. 13.) 



Red ; antennae, tibiae, tarsi, and apical part of femora black. Head rather large, 

 not much narrower (including the eyes) than the front part of the prothorax ; eyes 

 smaller and more widely separated than in other species of this genus (the space 

 between the upper lobes of the eyes measures in the type almost 3 mm. broad, whereas 

 it is not more than 2 mm. broad in specimens of the same size belonging to dehyi or 

 ofricana). Prothorax widest across the base ; slightly narrowed, with its sides sinuate, 

 between the base and the middle ; its upper surface nitid, minutely and sparsely 

 punctate, feebly impressed along the middle. Elytra subcoriaceous, impunctate and 

 very glossy. 



Length 28 ; breadth 8^ mm. 



Hab. Mokia, S.E. Ruwenzori, 3400 ft. One female example. 



This species greatly resembles H. africana Auriv. both in colour and sculpture, but 

 may be readily distinguished from it by the form of the prothorax and by the smaller 

 and more widely separated eyes.

Mubuku Valley, E. Ruwenzori, 6000-13,000 ft. Several examples of both sexes. 



This species was founded upon a single male specimen from Entebbe in Uganda, and 

 was described by me as follows : — " Mandibles long, divergent from the base to the 

 middle and then strongly incurved, so that when closed they circumscribe a somewhat 

 transversely elliptical space ; they are gradually and regularly narrowed from the 

 middle to the apex. The antennas do not reach beyond the middle of the elytra ; the 

 first joint is relatively as long as in C. forcipatus Har., but somewhat thicker, and each
