NOVITATES ZOOLOGICAE XXI. Ull4. 5^29 



The rostrum is much less stout than in To^j/wf^ res, recalling that of Stenocenis. 

 It bears a sharply-marked central carina on the underside. The labiophore is 

 quite smooth and polished. The antennal groove is shorter and more transverse 

 than in Tophodcres, and a well-marked carina runs ventrally from the hind edge of 

 the groove to the lower part of the eye. The latter is mnch more finely granulated 

 than in Tnphoderes, and is truncate or truncate-emargiuate in front. 



The basal angle of the pronotnm is very acute, the dorsal carina, which is 

 almost straight in the centre or here feebly concave, being vertically above the true 

 basal edge at the lateral angles. The lateral carina does not quite reach the middle 

 of the sides in the species known to me. 



The intercoxal process of the prosternnm is narrower than in Tophoderes, and 

 the mesosternal one neither bitubercnlate as in Tophoderes, nor globose as in 

 Spitophoderes, but almost flat, declivous, with the sides non-angulate and the apex 

 truncate-rotundate. 



a. Eye broader than long. 



29. Atoplioderes dorsalis Qued. (1886). 



One pair from Kondu^. Quedenfeld says of his species that the lateral 



carina of the prothorax is abbreviated '^ paulo ante medium" which expression is 

 ambiguous. In the specimens before me, and also in anatinus, tbe carina does not 

 reach the centre of the sides. 



In A. dorsalis the pubescence is grey and dark olive, without an intermixture 

 of ochraceous. 



b. Eye longer than broad. Club of antenna looser and more strongly com- 

 pressed than in the previous species. In the S the anal sternite truncate with the 



angles produced into a sharp tooth. Here belongs A. acuta iu/hI us Kolbe (1895), 



which occurs in West and East Africa, being in the Tring Museum from Warri 

 (Niger), and Usambara.

 spots ; on the elytra before the middle on each side of the suture an irregular
