bluntly bi- or tri-incised, in tbe centre of the disk is a very broad 

 groove obliterated in front and behind, and a conspicuously broad, 

 sub-transverse impression on each side of the base, each elongate 

 reticulate puncture bears a very large, oblong ovate, dully 

 flavescent, sub-appressed scale, partly rubbed off, however, in the 

 only example I have seen ; scutellum strigillate reticulate at the 

 base, but obsoletely so at apex ; elytra very deeply sinuate laterally, 

 one-third broader than the prothorax, depressed, and having on each 

 side ten very plain, simple, impunctate striae the intervals of which 

 are plane, like the suture, and bear each a series of thick appressed 

 oblong ovate dull yellowish scales, slightly removed from each 

 other ; propygidium finely plicate transversely ; vertical part of 

 pygidium covered with scales similar to those of the elytra, and 

 issuing each from a broad, shallow puncture ; under side glabrous 

 except for a few scales on the pectus, the ante-coxal process of the 

 presternum being only slightly pubescent. 



Length 14-i- mm. ; width 6i mm. 



Hab. Southern Rhodesia (Hartley). 



This species is remarkable for its shape and vestiture. 



ASTOXENUS, n. gen. 

 Plate XLVIL, fig. 9. 

 Mentum plane but thickening on the outer face from about tbe 

 middle to the ligular part which is truncate at apex, widely 

 ampliate and deeply hollowed out, being half as wide across as the 

 whole length, deeply excavate, with the front edge notched in 

 the centre, the palps cavity is small, lateral ; upper maxillary lobe 

 armed with a single very long, very slender, and sharp tooth, 

 inner lobe provided with a less slender but also non-bifid tooth ; 

 clypeus convex in the centre, moderately carinate laterally and also 

 in the median part, anterior margin sub-diagonal laterally, nearly 

 straight but slightly sinuate in the centre ; antennas of Cremastochi- 

 licles ; eyes large but not bulging much ; prothorax narrowly con- 

 stricted along the anterior margin which is sharply carinate, sides 

 bluntly triangular, but the anterior part is a little more rounded than 

 the posterior which is oblique, the base being a little narrower than 

 the apex with the angles blunt but distinct ; scutellum sharply 

 triangular and as wide as the whole base owing to the very sloping 

 episterna and humeral part of the elytra which are sub-parallel from 

 the humeral part, deeply sinuate laterally, plane, slightly narrower 

 at apex than at base and bi-striate on each side of the suture ; 

 spiracle of the last abdominal segment strongly developed ; pygidium
