along seta and is similar in shape and sculpture to A. jubatulus ; 

 the elytra, however, are not depressed as in the latter species and the 

 convexity in the posterior part is very well marked, the striae are 

 slightly more finely punctulate and the intervals a little more sharply 

 convex, the puncture on the third interval which in A. jubatulus is 

 situated at about two- thirds of the length is set at a short distance 

 only of the median part in A. pilosulus, but the fringe of hairs along 

 the margin and the pubescence of the under side and legs are the 

 same in both species. 



I have seen only one female example of this species, which differs 

 .also from A. pilosulus in having slightly shorter and thicker antennae.

GEN. PLATYNUS, Bon. 

 PLATYNUS (MEGALONYCHUS) UMTALIANUS, n. sp. 



Black with the head shiny but the prothorax and elytra sub- 

 opaque, palpi, basal joint of antennae and femora pale flavescent, 

 tibiae slightly infuscate ; head impunctate ; prothorax equally am- 

 pliated laterally in the anterior and posterior parts, very slightly 

 angular in the middle, this angle is slightly sharper in the male than 

 in the female, the margin is strongly reflexed all round, the sides of 

 the posterior part are somewhat depressed, the median longitudinal 

 impression is very well defined, and the whole surface is very closely 

 shagreened ; elytra oblong for three-fourths of the length, and sub- 

 acuminate thence towards the apex which is strongly sinuate, they 

 are punctato-striate with the intervals slightly convex in the male, 

 planer in the female, and closely aciculate, the three punctures on 

 the third interval are well defined, and the sutural angle is very 

 sharp. 



Not unlike P. latipennis, Boh., but the prothorax is not so broadly 

 .ampliated, and the surface is more plainly shagreened. 



Length 13^-14 mm. : width 5-5J mm.
