1886.] REV. H. S. GORHAM ON NEW COLEOPTERA. 155 
Head with a few scattered but distinct punctures; club of the 
antennee rather lax and dull. Thorax shining, not punctured, but 
with the surface uneven; anterior margin deeply excavated for the 
head, and with the anterior angles turned inwards; the sides much 
rounded in front; the disk with a short central elongate impression, 
and a round one on each side; the sides much puckered. Elytra 
smooth and waxy, impunctate ; all the disk of a pitchy-purple tint, 
which in life was, as Mr. Lewis informs me, of a most beautiful 
violaceous colour. They have a double, not much elevated, tumidity 
each side of the scutellum. The humeral callus is much inflated, 
to the extent of about a quarter of the length of the elytra; this 
tumidity is scarcely carinate and not spinose; the reflexed margin of 
the elytra is complete, running as a fine line beneath the callus up 
to the basal angle; the epipleural fold is black and shining. The 
anterior tibize are very faintly incurved, and compressed into a shallow 
spoon-shaped hollow at their apices, and the middle pair are more 
strongly incurved at their tips, the hind pair slightly so; all the 
tibie have the apices pubescent inwardly; the hair at the tips is 
golden. 
Of this very singular and beautiful Spathomeles a pair were beaten 
off a dead branch in the jungle by Mr. Lewis at Dickoya, at 5000 
feet elevation. 
2. SPATHOMELES ORNATUS. 
S. decorato valde affinis, oblongus, niger, nitidus; elytris sub- 
violaceis, maculis tribus elevatis, una basilari rotundata, una 
ante medium transversa in medio constricta, una subapicali sub- 
lunulata, luteis. Long. 13-15 millim. ¢ @. 
Mas. Zlytris spina dorsali brevi obtusa, femoribus anticis, tibiis 
mediis ante apicem dentatis, tibiis posticis ante medium angu- 
lariter late dentatis. 
Hab. Assam. 
Very closely allied to S. decoratus, Gerst., and perhaps not more 
than a geographical form; the evident toothing of the hind tibiz is, 
however, very important, and the union of the two middle yellow 
spots, which in S. decoratus are, so far as I have observed, always 
separate, seems to point to a permanent specific difference. The 
spots are all rather more developed than in S. decoratus ; the basal 
one is round. 
One male and two female specimens. 
STICTOMELA, gen. nov. 
Corpus ovatum. Elytris convexis, maris haud spinulosis. Pro- 
thorax antice ampliato-rotundus. Prosternum apice truncatum, 
coxas anticas superans. Mandibule apice bidentate. Palpi 
mazillares articulo ultimo conoideo apice minute truncato. 
A genus very nearly approaching Spathomeles; the points in 
which it principally differs are, that in the males the elytra are not 
armed with a spine, and the prothorax is differently shaped, resem- 
bling more that of the Amphisterni of the second aceon without
