COLEOPTERA.

shortly ovate-subconic; pale ferruginous or rufous; basal joints glabrous, 
the remainder slightly pubescent. 
Thorax conic, nearly as long as the breadth of the base, which is more 
than thrice that of the apex; the latter truncate; sides rather strangulated 
behind the apex, thence emarginately obliquely dilated and slightly sinuate 
towards the base, with the posterior angles extremely extended laterally, 
very acute; base, from the angles to more than half the distance to the 
middle, slightly oblique and sinuate, or subtruncate, thence abruptly ob¬ 
liquely produced towards the elytra, with the middle widely truncate, 
truncature slightly emarginate in front of the scutellum ; convex, having 
a large longitudinal elevation in the middle reaching the base and the 
apex, and another, tuberculiform, at each side of this, elongate, basal, 
reaching scarcely to the middle; a channel rather deep at the base, gra¬ 
dually more obsolete towards the apex, divides the central elevation, and a 
deep rather wide impression separates it from the adjacent tubercle; the 
base is also impressed between that tubercle and the posterior angle; 
densely punctate, with the elevations transversely and finely rugulose; 
densely covered with a ferruginous-brown pile, leaving here and there de¬ 
nuded places upon the elevations; a large subtriangular basal spot of a 
lighter yellowish pile appears in front of the scutellum. 
Scutellum shortly subquadrate, with the middle of the apex emar¬ 
ginate, covered with a yellowish white pile, longitudinally divided in the 
middle (probably by an impression of the scutellum). 
Elytra broad, short, together as broad as long, scarcely twice the length 
of the thorax, of equal width with the latter; base of both united, semi- 
circularly emarginate in the middle for receiving the thorax and scutellum, 
then subobliquely and sinuately truncate towards the sides, having a short 
tubercle placed behind that of the thorax, and near the shoulder, which is 
also tuberculiform, within the lateral angles, and slightly continued by 
an obsolete ridge towards the apex; sides rather dilated to the third 
part of the length, then slightly narrowed towards the apex, where they 
are nearly as wide as at the base; apex of each elytron semicircularly 
rounded, with the sutural angle obtuse; convex at the sides, widely de¬ 
pressed in the middle along the suture; obsoletely punctate-striate; inter¬ 
stices transversely and finely rugulose, alternately convex and flat (the 
dorsal ones nevertheless all flat from the base to two-thirds of the length); 
that continued from the shoulder more elevated than the others, terminated 
above the apex by a callosity; pitchy, densely covered with a ferruginous-
