^ . Head fulvons, impunctate, the vertex with a small central spot, 

 eyes very large and prominent, each wider than the dividing space,

Hah. Beira (P. A. Shepparcl). 



Both sexes of this species agree in the structure of the 

 antenniae, but the latter are shorter in the female ; the eyes 

 in this sex are also much smaller and more widely separated. 

 H. hifasciata,Ja.c., is a closely allied species, but has simple 

 antennas and broader elytral bands.

 tarsi blackish, legs fulvous, thorax very finely punctured and granu-

 wrinkled, with a longitudinal sulcus at the sides. Length 4-4| 

 millim. 



Head bright metallic-green, very finely granulate, impunctate, with 

 a central fovea, laljrum fulvous, antennae very long and slender, black, 

 the lower three or four joints testaceous, all the joints, with the 

 exception of the second one, very elongate and nearly equal ; thorax
