100 Mr. David Sharp on the 



near the front angle, one in the middle, and one near the 

 hind angles ; it is scarcely excavate at the hinder angles, 

 but as it were obliquelj truncate, each angle of the 

 truncated part being a little prominent. Elytra more than 

 twice as long as the thorax, very little broader towards 

 their extremity, very coarsely punctured. Legs yellow. 



The male has the legs slender and simple. 



Four specimens ; found under dead leaves at Nagasaki.

 capite prothoraceque disco fuscis, elytris perconvexis, for- 

 titer punctatis. Long. 1 lin. 



This very i*emarkable and distinct species has somewhat 

 the form and appearance of Epurcea Ihnhata. Antenna3 

 yellow, gradually thickened from the 7th to the 11th joint ; 

 these joints rather darker than the others. Head nearly 

 black, reddish in front, the front margin very sti-ongly 

 elevated. Thorax reddish, with the disc much infuscate,

 Elytra of a shining-yellowish colour, very strongly punc- 

 tured, very convex both transversely and longitudinally.

In the male the middle tibiae are very slightly thickened 

 on the inner side in the middle, near the extremity a little 

 excavate and curved, the excavate part very finely serrate ; 

 the hinder tibite are very slightly emarginate above the 

 extremity.

This species is allied to P. atomnrlus, but is larger, and 

 has the antennje much stouter, and in the male the front 

 tarsi are distinctly dilated, and the intermediate tibias much 

 sinuate. It is slightly smaller than macro2)teriis, Avitli the 

 antennfe much stouter, and the front tarsi of the male 

 much shorter. The antenna are stout, yellow at the base, 

 infuscate at the extremity; joints 9 — 11 of large size. 

 Form and sculpture of thorax and elytra much as in 

 atomarius. 



In the male the anterior tarsi are short, but much dilated
