Xestocis singularis, n. .sp. 



Oblong, oval, glabrous, shining. Piceo castaneous in 

 color. Male — Epistoma reflexed, angiilate at sides, .slightly 

 marginate at middle. Front deeply concave, smooth. An- 

 tennae 10-jointed stout, third joint as long as fourth and 

 fifth together, fifth, sixth and seventh very transverse. First 

 two joints of club as long as wide, last joint longer. Eyes 

 moderate in size, but very prominent. Prothorax as long as 

 wide, wider than elytra, sides arcuate, hind angles rounded, 

 strongly margined at base and sides. The front angles rather 

 acute and extending across front as a carina into the porrect 

 blunt horns or processes. These horns are of very singular 

 .shape, being curved upwards and outwards at tip, with a thick 

 carina running lengthways with the horns. The upper edge of 

 this carina being convex and highest in the middle. Between 

 the horns, which are widely separated, is a .shining subquadrate 

 depression. iVt ba.se of horns on outer side it is strongly strigose. 

 It is also strigose at sides and across base of prothorax. Punc- 

 tures rather fine and uniform. Elytra narrower than pro- 

 thorax and less than twice as long, substriate. Punctures dual. 

 Large and foveiform ones in rows, and minute ones scattered 

 along interspaces. Beneath the prothorax is long before the 

 coxae, which are large and prominent, with a sharp carina 

 between them. The anterior tibiae are flattened and carinate 

 on outer edge, with a produced apical angle, rounded and finely
