new Species of Histericla3. 151 



late, transverse stria well-marked with sixteen crenellations ; 

 the antennai pale brown ; legs obscurely brownish. 



Similar in form and colour to T. capensis, Payk., but the 

 surface-sculpture of PaykuU's species is densely punctulate. 



Ilab. Usambara : Tanga, in tiie Mkulumusi caves. 



Trihalus puncticeps, sp. n. 



Breviter ovalis, sujDra couvesus, niger, nitidus ; fronte cum maii- 

 dibulis puiictulatis; pronoto irregalariter punctato, stria raar- 

 ginali iutegra; elytris stria sutuiali tenuiter impressa ; tarsis 

 t'erru<>iueis. 



L. 2 mill. 



Shortly oval, convex above, bhack and shining ; the head, 

 also the clypeus and mandibles, markedly and somewhat 

 densely punctulate, forehead impressed; the thorax, marginal 

 stria complete and continued beliiiid the neck, the disk very 

 finely and sparingly punctulate, laterally the points' are larger 

 but not so densely set as those of the head, the scutellar 

 depression is transversely but not conspicuously punctured ; 

 the elytra, stria3, outer humeral fine and complete, the sutural 

 very fine and not very distinct, abbreviated as usual in the 

 genus, and it scarcely diverges from the suture anteriorly ; 

 there are indications of other dorsal strias and the dorsal 

 punctuation is irregular with a tendency to run into double 

 longitudinal lines; the pygidia are much more finely and less 

 densely punctulate than the head ; the presternum, the ante- 

 rior lobe is distinctly punctured, the keel nearly smooth and 

 the lateral strias very slightly diverge at either end ; the 

 niesosternum anteriorly immarginate, sutural stria finely 

 crenate and almost straight ; the tarsi are ferruginous. 



The punctuation of the head is a marked character in this 

 species. 



Hah. Nilgiri Hills, 5000 feet (/7. L. Andreioes), 



Tribalus suturalis, sp. n. 



Breviter ovatus, parum couvexus, piceus, subopacus ; fronte piinctu- 

 lata baud impressa ; pronoto lateribus sinuato ; elytris striis 

 humeialibusintegris, dorsalibus incouspicuis, sutura post scutelluin 

 subtuberculata. 



L. 2i mill. 



Shortly oval, little convex, piceous, and somewliat opaque ; 

 the head closely punctulate, with a lateral stria before each 

 eye, forehead not impressed; the thorax sinuous along the 

 lateral edge, where it is obscurely reddish, the mar2-inal «^«-'-'
