General outline, form and size of middling specimens of Isac. 
Rhinotioides, Hope, Sch., hut quite differently coloured, the head more 
quadrate, the eyes less prominent, and the elytra conjointly more acute 
at the apex, &c. Head suhquadrate, somewhat shorter than wide, 
depressed posteriorly, with the forehead raised convex and wide; punc¬ 
tate-rugose, round the eyes densely, beneath and at the sides entirely, 
slightly whitish tomentose; pitchy brown, eyes black. Rostrum some¬ 
what ampliate towards the base and apex, where it, nevertheless, is 
a third narrower than the forehead; very slightly arcuate; pitchy, 
opaque and punctate-rugulose at the base, with a whitish tomentosity ; 
from the insertion of the antennae (basal third) to the apex denudate 
glossy, slightly punctulate, fuscous above and rufous at the sides and 
underneath. Antennae rufous, shaped as in Rhinotioides for the pro¬ 
portion of the joints between them, but longer and thinner, all the joints 
being more elongate. Thorax constricted behind the apex (which 
is truncate), roundly ampliate somewhat behind the middle; base trun¬ 
cate, broader than the apex; punctate-rugose; median canalicula shal¬ 
low and very narrow, obsolete anteriorly; covered above (like the head) 
with a brown opaque tomentosity; a very obsolete whitish line fills the 
canaliculation; at the sides and underneath entirely whitish tomentose. 
Scutellum subtransverse, small, whitish tomentose. Elytra *subangu- 
larly rounded and reflexed at the middle of the base, with the suture 
eallose, close to the scutellum ; shoulders obliquely rounded; sides 
somewhat straightened to the anterior fourth, then insensibly widened to 
the posterior sixth; finally, rather abruptly obliquely narrowed to the
