Sze-chuen. In the closely allied L, sinensis from Eastern 

 China, and L. castanea from Japan, the elytra have a smooth 

 and slightly raised submarginal line, of which there is no trace 

 in L. cequahilis. The lateral dilatation of the thorax is less 

 angulated than in sinensis, but not so completely rounded as in 

 castanea. The tooth of the claws is distinctly nearer the apex 

 than in either of the allied species.

An elongate, rather narrow, species, in some individuals cylindrical in 

 shape, the upper surface silky opaque with a pruinose bloom, and purply 

 reddish brown in colour. The head is thickly punctured, the clypeus very 

 shfirt, with sides strongly converging and rounded to the front, and the 

 middle of the front edge strongly notched and reflexed. The thorax is of the 

 same width as the elytra, rounded in the middle of the sides, the outer edge 

 impressed by a series of pores, but not crenulated, the hind angles distinct, 

 obtuse, the surface with thickly scattered umbilicated punctures. The elytra 

 have similar but much more widely scattered punctures, and two or three 

 very obtuse longitudinal costae besides the usual sutural one ; the lateral 

 margins of the elytra are strongly biiiexuous. 



LePIDIOTA PRiECELLENS, n. Sp.

Sze-chuen. Two male examples. 



Very similar to L. tridens (Sharp), which is found in the interior of 

 Cambodia and Siam, but larger, and the thorax much longer, owing to 

 the prolongation of the narrowing from the lateral angular dilatation to 

 the front. The clypeus is larger, the sides being a little more broadly 

 rounded. The lateral margin of the thorax is sharply crenulated. The 

 elytra are vermiculate -rugose throughout ; the anterior tibiie armed, as in 

 L. tridens, with three large and acute teeth. The under surface and legs are 

 dull greenish black, the breast, both margins of the femora, and inner 

 margins of the four posterior tibiae, clothed with long foxy-red hairs. The 

 abdomen is thinly clothed with minute pale scales. The antennal club is 

 equal in length to joints 2 — 7.
