humeral angles suh-acute, and the puncturation extremely dense 
and minute. Under surface very sparsely punctate. Legs 
moderately stout, the anterior four ciliated with red hair, the 
anterior tibiae tridentate. 
Long. 4, lat. If lines. 
164. Heteronyx scutatus, n.sp. 
Oblong-oval, reddish-testaceous, nitid, very minutely punctate, 
almost glabrous. Clypeus emarginate in front, the labnim 
showing in front of the emai’gination, the clypeal suture almost 
straight. Thorax of the same form as in H. suhfuscus, but more 
minutely punctate, and with the median line very indistinctly 
impressed on the anterior half. Scutellum elongate, triangular, 
obtusely pointed. Elytra slightly rounded on the sides, about 
thrice the length of the thorax, a little less densely and finely 
punctate than in H. suhfuscus, and with one stria on each side 
of the suture. Under surface and legs reddish-chestnut, sparingly 
villose, the latter short, the anterior tibiae tridentate. 
Long. 4, lat. 1|^ lines. 
165. Heteronyx transversicollis, n.sp. 
Oblong, piceous-red, nitid^ moderately densely and finely 
punctate, and clothed with a rather long cinereous pubescence. 
Head roughly punctate, the clypeus not extended laterally 
beyond the eye, and rounded and refiexed throughout, excepting 
a very small emargination in the middle, which scarcely permits 
the labrum to be seen in front. Thorax twice as wide as long, 
rather thinly punctate, the anterior angles a little produced and 
acute, the base slightly rounded and a little wider than the apex. 
Elytra of the width of the thorax and about four times the length, 
slightly rounded on the sides, finely but rather thinly punctate and 
tran.sver.sely sub-rugo.se, with one faint stria on each side of the 
suture. Legs reddish, anterior tibiso tridentate.
