159. Heteronyx rufopiceus, n.sp. 
Oblong, piceous-red, nitid, densely punctate, almost glabrous. 
Head short, minutely punctate, the clypeus longer than the head 
in the middle, slightly projecting laterally beyond the eye, widely 
rounded in front and a little reflexed, the suture distinct and 
arcuate, the labrum not showing beyond the edge of the clypeus. 
Eyes large. Thorax transverse, less densely and finely punctate 
than the head, the anterior angles prominent but not very acute, 
the base rather wider than the apex and scarcely bisinuate, and the 
angles rectangular. Elytra not wider than the thorax and three 
times the length, densely punctate all over, the punctures larger 
than tho.se on the thorax. Under surface piceous-brown, coarsely 
punctate, thinly fulvous-hairy. Legs reddish, thighs short, and 
broadly bellied, anterior tibise strongly bidentate. 
Long. 4J, lat. 2 lines. 
A variety of what I suppose to be this species is of a piceous- 
black colour. 
160. Heteronyx Froggatti, n.sp. 
Of a shorter and broader form than the last, of the same colour, 
more strongly punctate and glabrous. Head very thinly and 
clypeus densely punctate, broadly rounded in front, the clypeal 
suture slightly arcuate, the labrum not showing in front of the 
clypeus. Thorax transverse, much wider than the head, rather 
thinly punctate, wider at the base than at the apex, the anterior 
angles prominent and rather obtuse, the posterior almost rectan- 
gular, a small shallow fovea near each side about the middle. 
Elytra scarcely as wide as the thorax at the base, but widening 
considerably towards the apex, and a little under three times the 
length, coarsely but not densely and somewhat rugo.sely punctate. 
Under surface slightly punctate and hairy. Anterior tibiae ti’i- 
d entate. 
Long. 4, lat. 2 lines.
