mando of equal size. The mentum is oblong, scarcely constricted in the middle, and with the fore margin 
slightly angularly emarginate. The prothorax is obcordate, narrowed in front, the sides gradually rounded, 
the widest part being behind the middle, the hinder angles rounded off, and the hind margin nearly straight. 
There is a slender impressed longitudinal line down the middle of the pronotum, the hinder margin of which 
is also marked with two transversely ovate impressions; the prosternum is armed with a strong spine in front 
of the fore legs, and there is a smaller acute one in front of the mesosternum (fig. 9a). Each of the elytra is 
marked with six longitudinal striz not reaching to the base or apex, the interstices rugosely punctured or sub- 
granulated and setose. The spines of the legs are strong and acute.

The front margin of the clypeus is slightly emarginate ; the maxilla have both the mando and galea armed 
with two nearly equal thick teeth (fig. 7a); the mentum is subquadrate in its outline, but the middle of the 
dise is strongly angulated (fig. 74, seen from beneath; fig. 7c, seen laterally); the obliquely truncate anterior 
portion semicircular, and fringed with strong sete. The exposed part of the epimera of the mesothorax is 
clothed with whitish pile, as are also the lateral parts of the metathoracic epimera, with a large patch on each 
side of the metasternum, and a spot on each side of the second and third segments of the abdomen, those on 
the third being smaller than the others. The under side of the abdomen is not longitudinally channelled at 
the base, and the anterior tibie are obtusely bidentate (fig. 7d).

The maxille have the mando terminated by a short transverse acutely bifid spine; and the galea is of large 
size, nearly sickle-shaped, and terminating in two acute spines. The mentum is cup-shaped, transversely 
truncate at its front margin, which is vertical (figures 8a, 84, 8c, and 8d, seen in different positions). The 
prosternum has a deflexed spine in front. The anterior cox are dilated with a broad emarginate depression in 
front, the produced basal angle with a large impressed puncture. The fore legs have the tibie rather narrow 
and slightly arched outwardly, with the apex rather broad and bidentate; the tarsi are rather short in the fore 
legs. The elytra have the sutural margin slightly depressed; between the suture and the middle of the dise 
are four punctured, longitudinal strie with the interstices rather raised and arched, and finely punctured, adjoining 
the third stria (and between it and the lateral margin) is a fourth abbreviated stria, the punctures of these striz, 
being aciculated and semioval, open behind, the lateral margin thickly covered with small oval punctures. The
