South African Coleopterous Fauna. 247 



The male is not unlike in shape 31. promts, Per., but the elytra 

 are more ampliated laterally ; the female is very different from that 

 of M. promts. 



MlCRANTEEEUS LYDENBURGIENSIS, n. Sp., 



Plate XIII., fig. 7. 



Male : Black, with the elytra reddish-brown ; head and prothorax 

 plainly aciculate and extremely finely pubescent ; prothorax a little 

 more ampliated laterally than usual, and on that account only one- 

 fourth narrower than long, and bearing a faint longitudinal median 

 impressed line ; elytra glabrous, sub-acuminate-ovate, twice as broad 

 across the median part as at the base, strongly sloping, but hardly 

 declivous from two-thirds of the length, very little convex and 

 covered with closely set acuminate tubercles which are less well 

 defined in the anterior median part of the disk, and are disposed in 

 two indistinct series, often quite obliterated on the hind slope, 

 sides irregularly punctured ; legs very long and slender, first joint 

 of the anterior tarsi conspicuously dilated. 



Length 11^ mm. ; width 7 mm. 



Female : Covered all over with an appressed greyish pubescence ; 

 prothorax broader, slightly shorter and more ampliate laterally, the 

 longitudinal median line slightly more distinct ; elytra more ampliated 

 than in the male, but also somewhat elongate-ovate, but only one- 

 third broader across the median part than at the base, convex and 

 much more declivous behind than in the male, granulate laterally 

 along the outer costa, and having only a few scattered, small tubercles 

 in the posterior part of the elytra where these tubercles are slightly 

 seriate at a short distance from the suture, which is not raised. 



Length 11 mm. ; width 8 mm.

This species has no close ally, but the female resembles somewhat 

 that of 31. devcxus, Per. 



MlCBANTEEEUS GASANUS, n. Sp., 



Plate XIII., figs. 5, 6. 



Male : Black, with the background of the elytra terrenous ; head 

 and prothorax finely aciculate, the latter part is of the usual shape 

 obtaining in the South African species, i.e., one-third broader than 

 long, and with the median part of the sides rounded and slightly 

 .ampliated ; elytra rounded at the shoulders, twice as broad across
