396 Descriptive Catalogue [1896. 



the third interval of the elytra, by the smaller size and the shape 

 of the prothorax, the posterior angles of which are hardly defined, 

 and the outer sides, which are nearly straight instead of being 

 slightly rounded as in S.Herbsti; the elytra are also more parallel 

 for two-thirds of the length. 



This is the only South African Scarites the male of which differs 

 from the female. The distinctive characters are — a broad dilatation 

 of the basal part of the left overlapping mandible, a broader head, a 

 slighter ampliation of the prothorax at the base, and slightly more 

 linear and less convex elytra.

Subcylindrical, moderately shining ; head plicate in the anterior 

 part, even between the frontal depressions, which are narrow ; 

 paragenae hardly projecting ; prothorax somewhat cylindrical, 

 very little narrower across the basal angles than at the apex, 

 lateral part of the base diagonal, median part slightly sinuate and 

 not projecting behind ; elytra parallel with the humeral angle 

 moderately projecting, convex, very slightly striate or not striate at 

 all, and with the intervals very faintly raised, except on the sides 

 where they are sometimes a little more convex, outer margin nearly 

 smooth, third interval, or that part of the elytra which should be 

 such, with two conspicuous setigerous punctures on the posterior 

 part ; anterior tibiae bidentate above the digitation. Length 15-

 little more ampliated in the posterior part, the humeral angle is 

 identical, but they are deeply striate with the intervals narrow and 

 subcarinate, the eighth one begins at a long distance from the base, 

 the outer margin is narrow and has a series of ill-defined punctures 

 in the posterior part, the two punctures in the posterior part of the 

 third interval are very conspicuous. Length 16-18 mm. ; width 

 5-5^ mm.
