496 My. F. P. Pascoe on some 
Closely allied to P. longipes, but more richly coloured, the pro- 
thorax broader in the middle, and the base much broader than the 
apex; the antenne of the male more than twice as long as the 
body, the last five joints especially longer compared to the same 
joints in P. longipes. 
Promeces longicollis. 
P. angustior, nitide viridis vel cyaneus, antennis nigris; pro- 
thorace elongato, tenuato, disperse punctato; elytris corrugatis, 
dense punctatis. Long. 5 lin. 
Hab. Natal. 
Allied to P. viridis, but at once distinguished by its much longer 
and narrower prothorax, not densely punctured, and its longer 
muzzle. Colour as to violet, green, or dark blue, is subject to vary. 
Promeces austerus. 
P. (2) elongatus, saturate cyaneus; prothorace #reo-viridi; 
antennis nigris, articulo ultimo subulato; corpore infra viridi ; 
femoribus nitide violaceis. Long. 9 lin. 
Hab. Natal. 
Elongate, dark blue, nearly opaque, prothorax brassy green, 
antenne black; body beneath glossy green ; femora dark blue or 
violet, the four anterior strongly clavate, the posterior, as well as 
their tibiz, long and slender ; head and basal joint of the antennze 
coarsely punctured ; antenne longer than the body (¢?), mode- 
rately thicker upward, the last joint subulate, scarcely longer than 
the preceding one; prothorax stout, rounded at the sides; scutellum 
triangular ; elytra closely and minutely punctured, a faint longi- 
tudinal line on each; under surface glossy blue, abdominal segments 
with their posterior margins black. 
A somewhat dull-coloured species, the prothorax only 
slightly glossy, and in a certain light blackish. The 
male of P. longipes has 12-jointed antenneg ; species with 
eleven joints Lacordaire would exclude from the genus. 
Fauhreus has apparently done so in his genus Hypocrites, 
but, until we know the sexes of all the species, I am not 
disposed to adopt it. Promecidus of the same author is 
not adopted in the Munich Catalogue.
