Hister rugistrius, sp. n. 
Ovalis, convexus, niger, nitidus; fronte punctulata, biimpressa, 
stria antice recta utrinque interrupta; elytris striis 1*-3™ integris, 
4* et 5* apice conjunctis ; propygidio pygidioque dense ocellato- 
punctatis. 
L. 7 mill. 
Oval, convex, black, shining; forehead distinctly and 
somewhat densely punctulate, stria deep and straight ante- 
riorly, interrupted on either side, with two shallow impressions 
close behind it, mandibles externally marginate; the thorax, 
disk impunctate, lateral marginal stria very fine, external 
wide and rugose, shortened before the base, internal also wide 
and rugose, approaching the external posteriorly and turning 
inwards after passing it, fine and crenulate behind the head, 
interstice irregularly punctured, punctures clustered at the 
anterior angle ; the elytra, strie (including the internal sub- 
humeral) wide and deep, with the edges crenulate, 1-3 entire, 
fourth sometimes complete but very fine in the middle, some- 
times widely interrupted, with a short stria at the base and 
an apical appendage which joins the fifth, which is equally 
short, the sutural is apical but rather long and posteriorly 
turns away from the suture; the propygidium and pygidium 
are densely punctured, punctures distinctly ocellate, at the 
apex of the pygidium there is a small fovea, more or less 
distinct, with a narrow smooth margin behind it; the pro- 
sternum is without sculpture; the mesosternum is feebly 
sinuous in front, stria complete, margin narrow ; the anterior 
tibie are tridentate, the others multispinous. 
This species should be placed close to H. metallicus, Lew., 
from India.
