Haplotrachelus Teansvaalensis, Chaud. 



Size, shape, and colour of H. oviventris ; it differs from this 

 species merely in having the two outer intervals of the elytra acutely 

 carinate and the two last striae nearly smooth, not punctured ; the 

 intra-marginal carina slightly overhangs the outer margin, the 

 marginal series of punctures is not duplicated in the humeral part, 

 but the base has the two rows of granules ; the anterior tibise are 

 tridentate above the digitation. Length 25 mm. ; width 8 mm. 



Hah. Transvaal (Potchefstroom). 



Gen. MACEOTELUS, Chaud., 

 Monogr., he. cit., 1880, p. 14. 



Mentum hardly transverse, not deeply excavate, with a triangular 

 median tooth very broad at the base, inner lobes perpendicular for 

 half the length, diagonal in the other half, tip moderately sharp, 

 outer lobes inflated in the middle ; maxillae straight, hooked at the 

 tip ; ligula and palpi normal ; labrum very short, tripunctate in the 

 anterior part which is trilobate ; antennae reaching near to the 

 posterior angle of the prothorax, submoniliform, the basal joint 

 clavate, equal in length to the two following ones ; head one-third 

 longer than broad, sinuate over the eye ; genae small, not projecting 

 beyond the eyes, deeply and narrowly grooved on each side, the 

 groove reaching from the epistome to a short distance from the base, 

 the median part also grooved in the anterior part only ; prothorax 

 shaped as in Haplotrachehis , but distinctly aculeate in the posterior 

 angles, median part of the base not produced behind, outer sides very 

 oblique ; elytra of the same shape as Haplotrachelus, fused ; wings 

 wanting ; legs of Haplotrachelus. 



Maceotelus peesimilis. 



Black, either shining or subopaque on the upper part ; prothorax 

 as broad as the head and eyes at the base, rounded slightly from the 

 anterior part to the posterior angles, which are dentate, the lateral 

 sides of the base are very oblique, and the median part very slightly 

 produced behind and carinate ; elytra elongated, ovate behind, but 

 with the outer sides not ampliated, striate, with the intervals near 

 the suture moderately convex and the seventh one carinate, over- 

 hanging the eighth, the sutural one depressed; on the third stria 

 are four setigerous punctures, one near the base, one in the middle, 

 sometimes wanting, and two in the posterior part, the outer margin, 

 which is very narrow, is punctulate, and the base has a double series 

 of granules ; under side smooth with the lateral part of the abdomen 

 slightly shagreened ; anterior tibiae bidentate above the digitation. 



The facies of this insect is not unlike that of a small Haplotrachelus,
