Elytra with the five dorsal costse sharply tectiform, and the 

 carinate part not deeply impressed by transverse punctures .. germamts. 



Elytra with the costge nearly divided in two by the lateral 

 foveate punctures ; transverse carinas on the prothorax very 

 distinct 'promontorii. 



Elytra with the costae strongly foveolate laterally ; transverse 

 carinse on the prothorax slightly obliterated coilatus. 



Ehyssemus caeinatipennis, n. spec. 



Black, opaque, glabrous, palpi, and legs ferruginous red ; head 

 somewhat convex, roughly granulose, clypeus deeply emarginate 

 with the emargination arcuate and sharply angular on each side, 

 genge broadly triangular laterally, but without any trace of suture ; 

 prothorax nearly straight laterally, but very oblique towards the base 

 which is feebly marginate and has a distinct fringe of short, thick 

 bristles, it is not very convex, and beyond the anterior part, which 

 has a somewhat indistinctly transverse row of granules, there are two 

 entire, bluntly serrulate ridges reaching nearly from side to side, and 

 under these are two more which are interrupted in the middle and 

 united with one another by a longitudinal carina, the median space 

 left open representing the basal sulcus, along the base there is also 

 a more or less distinct transverse series of granules ; scutellum very 

 small ; elytra nearly oblong, but very slightly ampliate laterally past 

 the median part, convex, and with the humeral angles very sharp ; 

 they have on each side four very sharp, non-granulose carinate costae, 

 and the alternate ones are much less raised, and are interrupted by 

 regularly disposed transverse impressions, on the sides these alter- 

 nate costae are strongly serrate, the striae are narrow, rugulose, and 

 the sides of the costae are punctate, the punctuation is stronger 

 and more visible on the highly carinate ones ; under side slightly 

 rugose ; basal joint of posterior tarsi slightly longer than the apical 

 spur. 



Length 3f-4 mm. ; width 1|— 2 mm. 



Hah. Southern Ehodesia (Salisbury). 



Ehyssemus atramentarius, n. spec. 



Colour, shape, sculpture of the head and prothorax as in the 

 preceding species, but the sculpture of the elytra is different ; 

 the costae are tectiform and all of equal height, they bear on the 

 upper side a series of equi-distant, elongate granules separated by
