Very closely allied to the preceding species, but larger and also 

 l)roader in proportion ; the head is similar in shape and sculpture, 

 although the anterior part is slightly granulose ; the attenuation of 

 the anterior part of the prothorax is shorter, and the posterior part 

 is not quite so parallel ; the elytra are more distinctly ampliate past 

 the lateral sinuation, and have a much broader appearance, the; 

 punctate stria? are similar, but are much more obliterated towards 

 the base, and the punctures on the dorsal intervals, which are slightly 

 aciculate and not smooth, are hardly distinct ;' the propygidium has 

 three fine median longitudinal lines edging and dividing the very 

 fine, transverse stridulating folds ; the pygidium has a shagreened 

 basal, transverse band extending over one-fourth of the width, the 

 remainder being quite smooth ; the fold of the pygidium, which is 

 very distinctly carinate and wide, has a broadly triangular impression 

 in the median part ; the anterior tibiae are as in the preceding species, 

 but the inner claw of the anterior tibioe of the male is more emargi- 

 nate outwardly. 



Length 18-20 mm. ; width 10-11 mm. 



Hah. Mozambique (Eikatla). 



My examples are a little smaller than King's type, and the cephalic 

 tubercles are more developed. The genital armature is of the same 

 shape, but a little broader in proportion to the size. 



Hetekonychus infrictus, n. spec, 

 J Phi^L XL., fig. ± 



Black, very shining on the upper side, chestnut-brown underneath ; 

 head with a distinct median depression, frontal carina distinct laterally 

 in front of the eye, but obliterated from there, clypeal carina distinct 

 laterally and produced on each side into the median part into a short, 

 triangular, aculeate projection or small tubercle, the median impres- 

 sion and the clypeus are rugosely shagreened, and the clypeus is 

 distinctly and sharply bi-dentate ; prothorax impunctate, little convex, 

 slightly attenuate laterally for about one-third of the length, and 

 nearly, but not quite, parallel from there ; scutellum impunctate ; 

 elytra a little ampliate past the ante-median lateral sinuation, very 

 weakly punctato-striate in the dorsal part and with the second 

 stria nearly obliterated at some distance from the base, supra-lateral 

 striae and intervals, as well as the posterior rounded part, deeply and 

 closely foveolato-punctate, there is no puncture on the anterior part
