4G6 Mr. G. 0. Cliampion on 



spoon-shaped behind, and bordered on each side by a slender 

 rectangular plica (the three together forming a cruciform 

 flavous prominence), the space in front of the two excava- 

 tions raised (tlie face appearing long and bifid above, as 

 seen from the anterior aspect) ; antennae long, stout, 

 })ectinate. Prothorax transverse, obliquely narrowed from 

 the middle to the base ; abruptly dei)re>sed, deeply trans- 

 versely foveate, and produced into a flattened, raised, horn- 

 like prominence in the centre in front, the fovea preceded 

 by an angular elevation. Elytra wider than the prothorax, 

 subparallel, bluntly rounded at the apex. Anterior tarsal 

 joints 1 and 2 thickened, 2 raised above the base of 3, black 

 at the tip. 



Length 5 mm. 



Hab. S. Africa, Beaufort West [Purcdl, in Mns. Cape 

 Town). 



One male. A very remarkable insect, difficult to describe, 

 and comparable only with H. lamelliger, from which it is at 

 once distinguished by the sliorter, posteriorly-narrowed, 

 sharply trimaculate prothorax, the metallic femora, and the 

 elongate cavities on the head (these appearing triangular 

 when viewed in profile), which are separated by a narrower 

 anteriorly-depressed lamella, this being bordered by J-l_- 

 shaped flavous folds, together forming a cruciform elevation.

cJ . Antennae very long, rather slender, wholly testaceous, 

 joint 3 perceptibly longer than 4, 3 and 4 without smoother 

 area beneath ; head (PI. XIII. fig. 14) very broad, in great 

 part testaceous, the inter-ocular excavation extremely deep, 

 transversely nigro-lineate within, the vertical juxta-ocular 

 prominence compressed, dentiform, rather small, and sepa- 

 rated from a larger, oblique, black elevation behind it by 

 a deep oblique groove ; prothorax transversely subquadrate, 

 notched at the sides before the base, with an extremely 

 large, broad, triangular, opaque space on the disc, extending 

 from near the anterior margin to the base, for the rest 

 testaceous ; elytra blue or bluish-green, densely punctate ; 

 abdomen and legs testaceous ; anterior femora thickened, 

 obliquely sulcate and strongly binodose at the apex above ; 

 anterior tarsal joint 2 slightly raised over the base of 3, 

 nigro-pectinate at tip.
