BLACKBURN AND SHARP—On some New Species and Genera of Coleoptera. 189 
The two individuals described are probably males: they have the rostrum 
broad and much punctate, and becoming just perceptibly broader from the base 
towards the apex, but without any dilatation near the insertion of the antenne. 
This species occurs in company with H. wollastoni. 
D.S. 
Heteramphus hirtellus, n. sp.—Latiusculus, piceus, in thorace et in elytris 
erebre setosulus; thorace majore; anterius angustato, crebrius fortiter punctato, 
dorso ante basin foveolato; elytris striatis, striis fortiter punctatis. Long. (ine. 
rost.) 5 m.m. 
This is a very distinct species, similar in form to H. wollastoni and H. foveo- 
latus; it is readily distinguished by the setulose surface and more pallid colour, 
and the smaller tarsi. The thorax is rounded at the sides, not margined at the 
base. The elytra are striate; and the striz bear coarse punctures; the fourth 
and fifth striz are much abbreviate behind, and are deeper than the others. 
The unique individual is in bad condition, and has been covered with some 
dirt or exudation, the removal of which has been difficult and only partially 
effected. It is no doubt a male; the rostrum is densely and rugosely punctured, 
and quite evidently dilated at the insertion of the antennz. 
Very rare; found by sifting dead leaves, high up on the mountains. No. 377. 
DS: 
Heteramphus' cylindricus, n. sp.—Angustulus, subopacus, niger, antennis, 
tarsisque piceis; thorace elongato, minus crebre punctato; elytris leviter striatis, 
striis obsolete punctatis. Long. (ine. rost.) 44; lat. 1} m.m. 
This species has somewhat the appearance and form of a narrow Baridius or of 
a Mecinus. The thorax is rather rounded at the sides, not margined at the base, 
rather sparingly, not finely, punctate; the punctures more obsolete on the disc. 
Elytra only as broad as the thorax, not shining, rather faintly striate; and the 
strie bearing only very distant and indistinct punctures; but the sculpture is 
rather more accentuated near the apex; the pseud-epipleuree not so definitely 
marked off as in the other species. 
I have only a single individual of uncertain sex. 
Two examples of this species have been found in company with H. wollastoni and H. foveatus.
