discoidal impression reaching from the median part to the anterior 
margin which bears a small tubercle in the centre, and it is covered 
on the sides with somewhat broad but closely set punctures having 
scabrose intervals, but the punctures in the median impression are 
not very closely set, and the intervals are smooth; scutellum not 
very distinctly punctured; elytra deeply punctured, the punctures 
are equi-distant, and along the basal part, the intervals are slightly 
raised; pygidium covered with equi-distant foveolate, shallow 
punctures separated by a narrow interval; abdomen with squamose 
hairs laterally, not depressed in the centre, penultimate segment. 
nearly twice as broad as the one preceding, ultimate one broad and 
convex ; pectus without pubescence; anterior tibiz tri-dentate, basal 
tooth very short; all the tarsi are missing in the only example I 
have seen, and which closely resembles H. montana, Brsk. 
Length 12 mm.; width 54 mm.

HOLISONYCHA, n. gen. 
Mentum strongly incised laterally near the ligular part, and very 
sharp at apex, labial palpi inserted laterally, the other buccal organs 
as in Sechizonycha; the antennal club of the male is as long as the 
pedicel the joints of which, with the exception of the two basal 
ones, are very small and closely set, the third being hardly longer 
than the fourth; the head and body are those of Schizonycha, but 
the long and slender claws are not much curved, and are simple at. 
the tip. 
HOo.LIsONYCHA MELLILA, n. spec. 
Light brick-red, or pale testaceous, shining, each puncture on the 
upper side with a most minute hair; head small, clypeus truncate 
with the outer angles rounded, hardly emarginate in the centre, clypeal 
carina very slightly arcuate, suture indistinct, basal carina distinct, 
slightly sinuate in the middle; clypeal surface covered with irregular 
punctures having raised intervals, frontal surface plainly granulose ; 
prothorax not much ampliated laterally towards the median part, 
and attenuated thence to the basal angle which is distinct, but not 
very sharp, outer margin somewhat crenulate in the posterior part, 
and ciliate, surface covered with round, scattered punctures. 
separated by smooth intervals, the punctures are more closely set on 
the sides and along the anterior margin; scutellum impunctate; elytra 
elongated, cylindrical, the punctures somewhat apart; pygidium 
not distinctly punctate ; abdominal segments not deeply punctate
