1886.] REV. H. S. GORHAM ON NEW COLEOPTERA. 1.55 



Head with a few scattered but distinct punctures ; club of the 

 antennae 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, im punctate; 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 cariuate 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 tibiae 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 

 tibise 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. cJ $ . 

 Mas. Elytris spina dorsali brevi obtusa, femoribus anticis, tibiis 

 mediis ante apicem dentatis, tibiis posticis ante medium angu- 

 lariter late dentatis. 

 Rab. Assam. 



Very closely allied to 8. decoratus, Gerst., and perhaps not more 

 than a geographical form ; the evident toothing of the hind tibiae 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 hand spinulosis. Pro- 

 thorax antice ampliato-rotimdus. Presternum apice truncatum, 

 coxas anticas superans. Mandibulce apice bidentatce. Palpi 

 maxillares 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 section without
