Hysteichopus agilis, Per., 



Plate III., fig. 6, 



Trans. S. Afric. Phil. Soc, vol. vi., pt. ii., 1892, p. 97. 



H. altecostatus, Per., loc. cit., p. 97. 



Black, shining ; antennge, palpi, and legs red ; prothorax sub- 

 elongated, almost cordiform, a little convex in the centre, with a 

 narrow longitudinal groove, the sides but little depressed, with the 

 outer margin raised but recurved in the posterior part ; elytra elon- 

 gated, suboblongo-ovate, narrowly striate with the intervals carinate, 

 the third one with five punctures— that number of punctures is, how- 

 ever, irregular ; under side black, shining ; tarsi long ; claws with 

 six long teeth on each side. Length 16-17 mm. ; width 5-6 mm. 



Hab. Cape Colony (Cape Town, Grahamstown). 



The example which I have described under the name of altecostatus 

 seems to me to be an aberrant specimen in which the alternate 

 intervals of the elytra are more raised and acute than the intervening 

 ones. 



Hysteichopus tenuicollis. 



Black, moderately shining ; antennae black, pubescent ; head 

 smooth ; prothorax ampliate below the apex, elongate, narrowing 

 gradually from past the anterior part to the base, which is one-third 

 narrower than in the anterior inflated part, closely and conspicuously 

 plicate transversely, narrowly grooved in the centre, and with a 

 lateral depression on each side, reaching from a little above the 

 middle to near the base, outer sides hardly depressed, margin acute, 

 recurved posteriorly ; elytra a little broader than the prothorax at the 

 base, gradually ampliate to a very short distance from the apex, deeply 

 striate with the intervals narrower and carinate, the third one with 

 four punctures ; under side shining ; tarsi very long, the under part 

 covered with thick bristles in both sexes ; claws with five moderately 

 long teeth on each side. Length 16-18 mm. ; width 5^-7 mm. 



Hab. Natal, Zululand (Eshowe). 



Sub-Gen. ASTUS. 



Hysteichopus pezedatoe. 



Black, shining ; antennas and palpi black ; head punctulate on the 

 sides, smooth in the centre ; prothorax elongate, cordiform, grooved 

 in the centre, with a small impression on each side at the base, the 

 outer margins acute but not recurved ; elytra broader than the pro- 

 thorax at the base, gradually ampliate behind, where they are nearly 

 twice as broad as at the apex ; deeply punctuato- striate with the 

 intervals carinate, the third one with five deep punctures ; under
