356 Mr. G. Lewis on neiv Japanese Cohoptera. 



Keddisli brown, somewhat shining', elytra a little darker; 

 the head uneven above and irregularly |)unetured ; the thorax 

 widest about the middle, uneven and punctured like the head, 

 impression behind the neck shallow, in one example almost 

 eflfaced ; the hind angles are obtusely rectangular ; the 

 scutellum triangular, feebly arched at the sides, wholly sculp- 

 tured on surface, with a few punctures dispersed over it ; the 

 elytra are ovate, marginal interstice narrow and of even width 

 throughout ; striae obscurely punctured, interstices densely 

 sculptured and feebly rugose or uneven. 



Hah. Ketoi. 



The sculpture noticed in these species is peculiar to the 

 genus ; when it is feeble it resembles the surface of tanned 

 leather^ when dense and well-marked, as it is on the scutellum 

 of L. Snou-i, it resembles the scul[)ture so familiar to ento- 

 mologists on the wing-cases of Agrili. 



Pteroloma discicollej sp. n. 



Rufo-hruuneum, vix uitidum ; thorace disco nigro, angulis anticis 



promineutibus. 

 L. 4 mill. 



Reddish brown, somewhat shining ; epistoma and disk of 

 the thorax black or])iceous ; the head impunctate but uneven ; 

 thorax, the hind angles rectangular, sides feebly bowed, anterior 

 angles prominent, the thorax being cut out in front to receive 

 the head ; the disk is black and convex, the sides longitu- 

 dinally impressed and spread outwards; the scutellum trian- 

 gular and without sculpture ; the elytra, margin elevated, 

 marginal interstice narrow, the second and third striai from 

 the outer margin join at the base, the strige are somewhat 

 fine and punctulate ; the wing-cases are wider than the thorax 

 at the base, with a somewhat elliptical outline to the base. 



I have one example, evidently a variety, in wliich the 

 antennse, head, and legs are infuscate. 



Bab. Main island. I took six or seven specimens from 

 under small stones on the summit of Nantaisan, 20th August, 

 1881.
