622 MB. MABTIN JACOBY OS NBW [NoV. 6, 



CE. jamaicensis is readily distinguished by its very transversely 

 shaped thorax and the entirely impunctate and violaceous elytra. 

 It is the only species known to me from Jamaica. 



(Edionychis pbinceps (Clk. CataL). (Plate XXXVIIl. fig. 4.) 



Widened posteriorly, black ; thorax impunctate, black, the sides 

 ilavous ; elytra metallic blue, rugose atid finely punctured, the apex 

 flavous. 



Length 3 lines. 



Head with a few fine punctures, blackish, the eyes rather closely 

 approached, frontal elevations oblique, clypeus flavous ; antennae 

 slender, extending beyond the middle of the elytra, black, the fourth 

 joint slightly longer than the third, all the joints rather elongate and 

 pubescent ; thorax strongly narrowed in front, the sides moderately 

 rounded, the anterior angles thickened but scarcely produced 

 outwards, the disc impunctate, black, the lateral margins flavous, 

 posterior margin perfectly straight ; scutellum black ; elytra rugose 

 and finely punctured, metallic blue, a triangular spot at the apex 

 flavous, the outer edge of the epipleurse flavous, the inner portion 

 black ; underside and legs black. 



Hab. Brazil or Bogota. 



Clark gives Brazil as the habitat of this species ; a specimen in 

 my collection has Bogota as the locality attached to it, but I am 

 unable to say whence I obtained it. The species may be recognized 

 by the rugose elytra and the colour of the thorax. 



QjIdionychis peedtiana, n. sp. 



Flavous, the intermediate joints of the antennae black ; head and 

 thorax impunctate ; el}i;ra extremely flnely punctured, bluish black, 

 the apex flavous. 



Length 3 lines. 



Head flavous, impunctate, rather flattened, the frontal elevations 

 feeble; the antennae not extending to the middle of the elytra, the 

 lower four joints and tlie apical one flavous, the others black, third 

 and fourth joints equal ; thorax much narrowed at the middle, the 

 sides strongly widened, their margins nearly straight, the anterior 

 angles acutely produced but not dentiform, the surface impunctate, 

 flavous ; scutellum black ; elytra widened at the middle, the disc 

 extremely finely and rather closely punctured, bluish black, the 

 extreme apex in shape of a narrow transverse band, flavous ; elytral 

 epipleurae, the underside, and legs flavous. 



Hab. Peru. 



Allied in coloration to (E. horjei, Jac, but the antennae are of 

 different colour, the thorax differently shaped, and the elytra of a 

 blackish blue. 



(EnioNTCHis BESKii (Clk. CataL). 



Black, the sides of the head and the thorax flavous; elytra black, 

 finely punctured, the extreme lateral margin and a spot at the apex 

 flavous.
