Mr. C. O. Waterhouse on new Coleoptej-a. 449 



underside near the apex ; the intermediate and posterior 

 femora with a much smaller tooth. Epipleural fold of the 

 elytra not very broad, narrowed to the apex. 



This interesting genus must be placed next to Diceroderes. 



Mechanetes cornutus, n. sp. 



Niger, opacus ; thorace minute granuloso ; elytris fortiter striato- 



punctatis. 

 Long, 16 millirn. 



Head strongly and closely punctured. Thorax a very little 

 longer than broad, with small conical projection at the sides 

 behind the middle ; anterior angles effaced ; disk with a slight 

 central impression. Scutellum small, triangnlar. Elytra at 

 tlie base not broader than the base of the thorax, gradually 

 wider to the middle and then narrowed to the apex ; the sur- 

 face extremely finely granular ; with lines of strong punctures, 

 the punctures separated from each other ; the dorsal inter- 

 stices flat. The undulating sublateral costa, when it reaches 

 the posterior declivity, turns suddenly outwards, and is con- 

 tinued a very short distance on the next interstice. Legs 

 thickly punctured.

LONGICORNIA. 



Lamiidse. 



Epicedia Wrayi. 



Nigra, pube obscure fulva vcstita ; singulo elytro macula rotundata 

 ante medium, altera parva sub humero, tcrtia majorc triangulari 

 lateral! nigro-velutinis ornatis. 



Long. 29 millim. 



Somewhat similar to E. maculatrix, but relatively longer, 

 especially in the elytra. The surface of the thorax is more 

 uneven, the tubercles on the disk are more elevated ; they are 

 placed as follows : — one small one in front of the central im- 

 pression (not a broad double one as in maculatrix) ; two on 

 each side, subconfluent longitudinally ; two posterior, placed 

 side by side. In the middle of the base of each elytron there 

 is a line of about eight small shining black tubercles, and 

 there are several other similar tubercles about the shoulder. 

 The spots on the elytra are similar to those in E. maculatrix^ 

 except the posterior lateral one, which is about half the size, 

 narrowed, and hooked down on the disk.
