342 Mr. G. C. Champion on the 
sparsely setose ; bluish black, the head nigro-neous; the 
basal joints of the antenne obscurely rufescent, the pro- 
thorax (an elongate black patch on the disc excepted) 
rufo-testaceous. Head small, narrow, somewhat produced 
anteriorly, the labrum concave, nearly as long as broad, 
rounded at the sides; eyes distant; antennz short, slender 
at the base, widened outwards, joints 8-10 serrate, 10 sub- 
transverse, 11 concave within, barely as long as 9 and 10 
united. Prothorax much wider than the head, about as long 
as broad, uneven, polished on the disc, sparsely punctate 
laterally. Elytra broad, long, widened to beyond the 
middle, rounded at the tip; densely, finely, rugulosely 
punctate, Legs rather short. 
Length (excl. head) 10, breadth 4 mm. 
Hab, Invia, Manipur (Doherty). 
One specimen. This species resembles Prionocerus cerulei- 
pennis and P. bicolor in shape, but it has the antenne slender 
at the base and joints 8-10 abruptly serrate; the head 1s 
small and narrow; the prothorax is red, with a black, 
anteriorly narrowed median vitta; and the elytra are broad, 
dull, and bluish black in colour. J. submetallica, Pic (1911), 
from Kandy, which has the elytra red, except at the tip, 
seems to be an allied form.

Hab. S. Inv1a, Wallardi in Travancore [type], Anamalai 
Hills, alt. 1100 metres (H. L. Andrewes). 
This species is easily recognizable by the very short fourth 
joint to the antenne, the bluish-green head, elytra, under 
surface, and legs, the testaceous prothorax, and the partly 
testaceous basal joints of the antenne. The three females 
from the Anamalai Hills in the Andrewes collection have 
joints 5-10 of the antennz cyaneous, considerably widened, 
and distinctly serrate, these joints, according to Bourgeois, 
being broadly serrato-dilatate in the ¢; his definition of 
the. antenna as “subfiliform” is misleading. The sutural 
angle of the elytra in 9 is dentiform, as described by Pie.
