H. OCCIDENTALIS, Sp.nOV. 
Minus elongatus ; postice leviter dilatatus ; minus nitidus ; 
ferrugineus, pilis suberectis sat brevibus vestitus; capite crebre 
crasse, prothorace minus fortiter minus crebre, elytris fortitei 
squamose minus crebre, pygidio sparsim minus fortiter, punctu- 
latis ; hoc capillis longioribus erectis vestito. 
[Long. 5, lat. 3^ lines. 
Clj-peus strongly emarginate in the middle, its margin enfeebled 
(but not wanting) in the extreme centre ; clypeal suture distinct 
and sub-angulate, surface of clypeus nearly continuous with that 
of rest of head. Prothorax two-thirds again as wide as its 
length down the middle, its width across front equal to its length, 
its front lightly emarginate, with angles but little produced ; its 
sides diverge arcuately to behind middle and then curve round to 
base with which they form a decided obtuse angle, the base is 
gently bisinuate, and but little produced backward in the middle. 
The transverse wrinkling of the elytra is very slight, their lateral 
fringe not continued round the apex which has a very narrow 
membranous border preceded by a transverse depression simulating 
a wide membranous border. On the underside the metasternum 
is very sparsely and finely punctured, the hind coxse much more 
closely and coarsely, the ventral segments moderately strongly and 
evenly but not closely ; the hairs in the ventral rows are rather 
fine and are continuous all across. The hind coxae are very little 
narrower than the metasternum, and are scarcely narrowed toward 
the middle line of the body. The hind femora are decidedly 
wider than the intermediate and have their inner apex evidently 
prominent though not angulated.
