South African Coleopterous Fauna. 281 



punctulate, epimera deeply punctate ; pectus finely strigillate ; legs, 

 very closely punctulate. 



Length 16 mm. ; width 5|--5f mm. 



Hab. Southern Ehodesia (Sebakwe), D. Dods. Damaraland, 

 W. C. Palgrave. 



DOKELOGENA ANGUSTA, 11. Sp. 



Ferruginous-red, shining, the five apical joints of the antennae 

 black, the others ferruginous ; much more slender than the preceding 

 species, from which it differs by the slightly shorter joints of the 

 antennae which, on that account, seem more knobby, the prothorax 

 which is quite parallel and as broad as long, and the more tectiform 

 interval of the elytra ; the punctuation on the prothorax is a little 

 deeper, and not so closely set. 



Length 10 mm. ; width 3 mm. 



Hab. Southern Rhodesia (Sebakwe), D. Dods. 



ASEMOGENA, n. gen. 



Buccal organs of Dorelogena, but the ultimate joint of the maxillary 

 palps is much less broad, and a little less obliquely truncate ; the 

 antennae are slightly more slender, but the shape of the joints is the 

 same ; the prothorax is plainly arnpliated and rounded laterally with 

 the anterior angles almost rounded, and the posterior sharp and 

 projecting. 



These generic characters may seem slight, yet the whole group 

 StrongylincB is so homogeneous that a difference in the shape of the 

 prothorax, which is really the main distinctive character from Dore- 

 logena, has some importance. - 



ASEMOGENA SIMPLEX, n. sp. 



Chestnut-brown, moderately shining ; head deeply and closely 

 punctate, the punctures are round and the intervals plane ; pro- 

 thorax very plainly rounded and arnpliated laterally, sinuate above 

 the base the angle of which is sharp and projecting, slightly convex 

 in the posterior part, sloping forwards, finely and closely punctate, 

 sharply marginate all round, and having a fine median longitudinal 

 impressed line, elytra sub-parallel, slightly sinuate laterally, deeply 

 punctato-striate from the base to the top of the posterior declivity, 

 and less deeply thence, the intervals are convex, tectiform for the 

 greatest part of the length, and finely yet deeply punctulate, abdomen
