38 Mr. M. Jacoby's Descriptions of New Genera and 



species differs from any of the others placed in this genus ; 

 the male has the last abdominal segment deeply longitu- 

 dinally sulcate ; in the female, this segment is simple and 

 pointed. 



Hemixantha sulconncetcns, sp. n. (Plate III, fig. 10.) 



Testaceous, antenna) (the basal joints excepted) lilack, tliorax finely 

 punctured, with five black spots, elytra punctured like the tliorax, 

 tlie margins testaceous, the disc piceous in shape of two longitudinal, 

 posteriorly more or less connected, bands, legs testaceous, tarsi black. 

 Length 4i millim. 



Head testaceous, the vertex iinpunctate, frontal elevations very 

 highly raised, subquadrate, bounded by a deep transverse groove 

 behind, piceous, lower portion of the face testaceous, eyes very large 

 and coarsely granulate or faceted, antenuaj robust, black, the basal 

 two joints more or less testaceous, second joint very small, third, tri- 

 gonate, the following joints scarcely larger, somewhat subquadrately 

 widened ; thorax one-half broader than long, or slightly broader, the 

 sides rounded at the middle, the anterior angles thickened and 

 slightly produced outwards, the surface rather closely and finely 

 punctured, the punctures somewhat deeply impressed, testaceous, 

 with three or five piceous spots, placed transversely, the middle ones 

 often united into a triangular larger spot, the middle of the base with 

 a shallow, more or less distinct fovea, scutelluni black ; elytra ex- 

 tremely finely and closely punctured, the apex nearly iinpunctate, 

 the entire disc occupied by a broad piceous band, which is divided 

 anteriorly by a more or less elongate stripe of the testaceous ground 

 colour, the sutural and lateral margins as well as the apex more 

 broadly, likewise testaceous ; below and the legs testaceous, the knees 

 sometimes stained with j^iceous, the tarsi entirely of that colour or 

 black. 



Hal. Beira (P. A. Sheiypard). 



In the male of this species, the eyes are particularly 

 large and prominent, and the antennoe are more robust 

 and longer than in the female ; the elytral dark band is 

 very variable in the amount of the anterior division which 

 in some specimens extends much further downwards than 

 in others, in which it assumes the shape of a flavous spot 

 only. 



Hemixantha dilaticornis, sp. n. (Plate III, fig. 15.) 



Fulvous, the apical joints of the antenna) black, strongly thickened, 

 thorax transverse, minutely punctured, elytra punctured like the
