<^ . Elongate, widened posteriorly, shining, thickly clothed 

 with long, soft, erect hairs intermixed with whitish 

 ])ubescence ; metallic-green, bluish-green, or brassy, the 

 head above (except at the sides behind the eyes or at 

 the extreme base), antennae (except at tip), and prothorax 

 testaceous, the abdomen in great part rufous, the apical 

 processes black ; the head and prothorax very sparsely, 

 minutely, the elytra densely, somewhat rugosely punctured. 

 Head (fig. 3) a little narrower than the prothorax, armed 

 with a stout, erect, ,blunt horn on each side near the eyes 

 and deeply transversely excavate between them, the cavity 

 extending for some distance forward exterior to a flattened, 

 trapezoidal, sharply-margined lamella extending backward 

 from the epistoma ; antennae moderately long, rather stout, 

 serrate. Prothorax strongly transverse, rounded at the 

 sides, the anterior margin raised into a triangular, basally- 

 widened, dentiform prominence, behind which is a transverse 

 excavation. Elytra moderately elongate, broader than the 

 prothorax. Pygidium (fig. 3 a) abruptly constricted and 

 deeply excavate on each side distally, and armed at the apex 

 with two long, curved, hook -like processes; the corresponding 

 terminal ventral segment with equally long, contiguous, 

 apically divergent processes *. Anterior tarsal joint 2 pro- 

 duced over the base of 3 above.

Hab. E. Africa, Kabete, Uganda [H. E. Box : iii., iv.

Five t^ c^, numerous ? ? , found with (^ and $ examples 

 of the closely allied H. kahetensis (No. 29), which has the 

 liead black, the horns short and angular, and the pygidial 

 structure very different in the ^ (^/- ^gs. 4, 4 «), and the 

 elytra blacker and more densely punctured in the two sexes. 

 H. 7'ujicorms, Champ., type, ^ , from Nairobi (1922), is 

 another similarly coloured form, with very different cephalic 

 and pygidial structure in the same sex. 



* //. kahetensis, ,5 , has two simihxr terminal ventral processes, not
