Oblong-oval, rather convex, black, shining; the head 

 smooth, stria complete, straight anteriorly, not deeply im- 

 pressed ; the thorax ciliate on the outer edges, lateral stri^ 

 complete and parallel to each other, inner stria continued 

 behind the neck and feebly angulate behind eyes ; the elytra, 

 stria? 1-3 and the inner subhumeral complete, 4 and 5 absent, 

 sutural rather fine, not quite reaching the apex and shortened 

 anteriorly by one third of the elytral length ; the propygidium 

 and pygidium are very finely punctulate and somewhat opaque, 

 apical margin of the latter is smooth and without a margin ; 

 the raesosternum is somewhat widely sinuous, stria rather 

 fine and complete ; the anterior tibia? have three robust teeth. 



This species belongs to Marseul's first section ; it is 

 smaller, but in some respects similar to H. fords, Sell. The 

 latter species is remarkable in having the thoracic stria inter- 

 rupted behind the neck.

Oblongo-ovatus, supra convexus, niger, nitidus ; froute punctulata,

 interstitiis latis, tenuissime punctulato ; elytris, striis 1-4 integris, 

 latis, crenulatis, 5 in medio, suturali ante abbreviatis ; propygidio 

 pygidioque grosse punctatis ; prosteruo baud striato ; mesostcrno 

 late sinuato, stria Integra antice recta.

The species is larger than, but in form similar to, U, longi- 

 colUs, Mars., and differs in having the interstices between the 

 lateral thoracic strite more than as wide again, in being with- 

 out the thoracic punctures and scratches, in the wider elytral 

 striae, in the middle of the propygidium being longitudinally 

 feebly raised, and in the anterior edge of the mesosternum being 

 widely and distinctly sinuous. In other respects it agrees 

 with H, longicoUiSy a common species at the Cape of (iood 

 Hope and Natal.
