3 70 M. Louis Peringuey on new genera and sj^ecies of 



laterally, deeply sinuated behind from a little beyond the median 

 part, and with the posterior part narrower than the anterior, moder- 

 ately convex, with the sides somewhat depressed, bi-impressed on 

 each side of the anterior part of the disc, and with a basal sub-lateral 

 longitudinal impression ; elytra not broader at the base than the 

 posterior part of the prothorax, but broadening a little below the 

 humeral angles and nearly as broad in the middle in both sexes as 

 the prothorax at its widest part, convex, dehiscent behind and with 

 six distinct, narrow costfe on each side. In the $ the anterior tibiaa 

 are moderately dilated at the tip, bi-dentate outwardly, while the 

 inner part is contorted and has a broad, semicircular groove, the 

 lower edge is sub-quadrate and bi-dentate, with the basal tooth 

 •pointing downwards, intermediate tibia3 incurved, deeply incised 

 inwardly, with the terminal part of the incision produced in a long 

 inner spur, posterior tibias moderately slender and a little incui'ved ; 

 in the $ the anterior tibiie are strongly bi-dentate outwardly and 

 not laminate internally. Length 19-22, width 11-12 mm. 



Hab. Zambezia (Salisbury). 



Allied to A. Uneatus, Gerst., in shape and sculpture, 

 but is easily differentiated by the shape of the anterior 

 tibia3. 



A. [Apodemns) marslialli, n, sp. 



Black, moderately shining, elytra with a light brown coating ; 

 head punctulate, and with two round impressions in the posterior 

 part ; prothorax ampliate laterally in the middle part, a little nar- 

 rower in the posterior than in the anterior part, basal angle sharp, 

 disk moderately convex, depressed laterally, punctured and with 

 two apical rounded impressions at the apex, two more on the median 

 part, and two on each side, the intervals separating these impressions 

 being smooth ; elytra moderately plane, convex and dehiscent behind, 

 nearly straight laterally, and set with series of short, rounded, 

 tubercles which are a little more raised in the alternate series ; 

 anterior tibia3 of the $ slender, curving but not much dilated at 

 the apex, bi-dentate outwardly, the inner apical part with a sharp 

 spine pointing downwards, intermediate tibiae slightly grooved out- 

 wardly and with a short median spine on each side, apical part a 

 little dilated. Length 26, width 13 mm. 



Hah. Zambezia (Salisbury). 



Easil_y distinguished from any other South African 

 species by the tuberculated elytra.
