WEST AFRICAN IIISTERIDAE 



there is a short apical obhque fifth stria; the propygidium is finely 

 and on the disc and base very sparingly punctured; the pygidiuni 

 is compressed except at the base which is impunctate and like that 

 of P. cregoei Lew. is on the same plane as the 

 propygidium ; the prosternum , the striae are broken \ 1 I 

 at the coxae near which on either sides is a small \) V 

 but distinct puncture or fovea (fig. 1); the meso- ^^^^^^^ 

 sternum is marginate and bisinuous. Fig. i. 



Resembles P. formosus Sch. and cregoei Lew. but it differs 

 by the fine punctuation of the head, deeper dorsal striae (which 

 have no specially wide interstice) and by the interrupted pro- 

 sternal striae and fovea. P. formosus and cregoei have the head 

 more distinctly punctured and the sternal striae are similar in 

 both species.

^l3r"aeus setig-er sp. n. 



Orbicularis, convexus, obscure niger, supra dense valide 

 pwictatus; setulis obscure flavis erectis seriatim; antennis 

 clava flava; mesosterno margine antico conspicue laevi; 

 pedibus obscure brwineis. - Long. 2 ^/^ mill. 



Orbicular, convex, obscurely black, very densely and strongly 

 punctate and clothed with setae; the antennae, the scape is rather 

 long and constricted at its base , the second joint is cylindrical 

 and truncate at both ends, the third is longer and markedly con- 

 stricted at the base, 4-8 joints are moniliform and the club is 

 liavous and conical and is without apparent sutures; the meso- 

 sternum has a wide impunctate margin and the transverse stria, 

 indicating the metasternal suture is markedly crenulate; the 

 anterior tibiae are multispinous. 



This species is larger but somewhat similar to A. setulosus 

 Mars. The antennae are differently formed and the mesosternum 

 has a wide smooth anterior margin. 



Hab. Farim, Portuguese Guinea.
