suture and the fifth intervals are raised, and each interval has at 

 apex a fascicle of long, greyish setae ; pygidium very long, hardly 

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

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

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

 covered with closely set granules ; legs rugose, anterior tibiae of male 

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

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

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

 .and narrow. 



Length 11-11|- mm. ; width 6 mm. 



Hah. Southern Ehodesia (Manica). 



Gen. TEAGISCUS, Klug, 

 Monatsb. Berl. Ac, 1855, p. 651. 



Buccal organs of Oniticellus, Scaptocneiuls, &c. ; head very deeply 

 emarginate semicircularly, prothorax depressed, abruptly declivous 

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

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

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

 abdominal segments, pygidium vertical ; metasternum d^ivided from 

 the mesosternum by a raised line; legs as in Onltis, but basal joint 

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

 put together, and twice as broad as the second. 



Although the generic difference between Tragiscus and OnitlccUua 

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

 of the basal joint of the posterior femora which, however, are also 

 more dilated in 0. egregius than 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.

Dull bronze, somewhat darker underneath, basal part of prothorax 

 spotted with small, flavescent dots, anterior part of elytra flavous 

 from the base to the median part ; head closely granulose, clypeus 

 ■deeply and semicircularly emarginate, the emarginate part is very 

 broadly and deeply grooved transversely, and the lower edge is pro- 

 duced into a perpendicular triangle, broad at base, and moderately
