and regularly rounded (rather more strongly in the $ ), not 

 constricted near the base ; the basal margin distinctly 

 carinate and broader than the apex ; the upper surface 

 closely set with low shiny granules, without any median 

 furrow, rather flattened on the disk, the dorsal outline being 

 almost level ; tlie scaling much denser in the ? than in the 

 $ . Elytra elliptical in $ , broader in ? and more sharply 

 acuminate behind, the basal margin truncate and strongly 

 carinate, the basal angles not projecting forwards, the apices 

 separately pointed ; the shallow stria? with very shallow 

 separated punctures, which are almost concealed on the 

 apical half when the scaling is dense ; the intervals almost 

 flat, finely rugulose, with a low humeral prominence at the 

 basal junction of intervals 7-9 in the ? , evanescent in 

 the $ ; the short subrecumbent scale-like seta? irregularly 

 placed, very dense where scaling is present and much more 

 sparse on the bare areas. Legs with the front femora only 

 slightly thicker than the others in both sexes ; all the tibia? 

 denticulate on the inner edge, the front pair with the outer 

 edge not curved at the apex in the $ . 



Length 9-12 mm., breadth 3 '5-5 '5 mm. 



S. Rhodesia : outskirts of Chirinda Forest, 4000 ft., 

 Melsetter district, 1906 (C. F. M. Swynnertori). 



Described from twenty-eight specimens. 



Differs from all the previously described species in having 

 no median thoracic furrow, and in the numerous irregular 

 seta? on the elytra. 



Iphisomus manicanus, sp. n. (PL XIII. fig. 6.) 



$ $ . Very closely allied to /. swynnertoni, sp. n., and 

 differing from it only in the following points : — 



The prothorax with a rounded spot of pale scales on each 

 side near the apical margin ; the legs much darker in colour, 

 the front tibia? being entirely black. Head with the eyes 

 more convex, the forehead loss striolate and without any 

 median stria. Rostrum much longer in proportion, especially 

 in the $ , the median furrow narrower and shallower. 

 Antenna with the scape appreciably longer, but joint 2 of 

 the funicle shorter (about half as long as joint 1, instead 

 of two-thirds), and the club more sharply acuminate. Pro- 

 thorax with the sides much more strongly rounded, especially 

 in the $ , the dorsal outline sloping forwards. 



Length 11 mm., breadth 4 mm.
