suture ami the fifth intervals are raised, and each intei'val has at 

 <ipex a fascicle of long, greyish settB ; pygidium very long, hardly 

 acuminate at tip, covered with setigerous punctures, nearly vertical, 

 but a little convex in the centre in the male, and liaving a triangular 

 tubercle very broad at base on each side in the female ; under side 

 covered with closely set granules ; legs rugose, anteiior tibiio of male 

 with a small pad of dense flavescent hairs, intermediate tibiic very 

 slender at base, amphated at some distance from it, and slightly 

 sinuate inwardly in both sexes ; tarsi slender, basal joint very long 

 and narrow. 



Length 11-lli mm. ; width G mm.

Buccal organs of OniticeUus, Scaptocncmis, &c. ; head very deeply 

 emarginate semicircularly, prothorax depressed, abruptly declivous 

 at apex, not rounded or ampliate laterally, slightly arcuate at JDase ; 

 scutellum distinct, elongate and acuminate at tip; elytra quite plane, 

 sinuate laterally, supra-marginal carina overhanging the edge of tlic 

 abdominal segments, pygidium vertical ; metasternum divided from 

 the mesosternum by a raised line; legs as iii Onitis, but basal joint 

 of posterior tibias much dilated and longer than all the other joints 

 put together, and twice as broad as the second. 



Although the generic difference betw^een TragiacHS and UnlticvUufi 

 of the group of 0. egrcgius is small, and consists mainly in the width 

 of the basal joint of the posterior femora which, how^ever, are also 

 more dilated in 0. egrcgius tlian in the other South African species, 

 the armature of the head in both the sexes, as well as the general 

 facies, militate in favour of retaining this genus. So far only one 

 species is known.
