third, and fourth equal in width and rather wide at the base, 

 narrowing gradually to the apex ; the antennas — third joint 

 distinctly longer than the second, three basal joints usually 

 reddish, others infuscate ; the legs are dusky or obscure 

 brown. 



In the Japanese series this species closely resembles E. fagiy 

 Lew,, but it differs in size, colour of legs, and pubescence.

Elaterfagi^ sp. n. 



Infuscatus, nitidus, longius fulvo-pubescens ; thorace subtiliter 

 punctulato ; elytris luteo-brunneis ; pedibus concoloribus ; an- 

 tennis infuscatis, articulis l°-3'" brunneis. 



L. 10-12| miU. 



Blackish, shining, with remarkably long tawny pubescence ; 

 the head evenly, not closely punctate, carina feebly sinuous 

 anteriorly ; the thorax narrowest anteriorly, widening out to 

 the base, not opalescent, punctuation on disk fine, but at the 

 anterior angle it resembles that on the head, median channel 

 very faint, not visible in one example ; the scutellum ob- 

 scurely punctured, obtusely acuminate behind j the elytra 

 clear yellowish brown, sutural stria fine and scarcely punctu- 

 late, the external striae become gradually deeper and more 

 punctate until after the sixth, interstices 2-4 rather wide and 

 flat, all finely punctulate ; the antenna — three basal joints 

 brownish, third joint one third longer than the second, dilated 

 joints infuscate ; the legs concolorous with the elytra. 



The thorax is more closely punctured than in E. orientah's, 

 the third joint of the antenna is longer, and the pubescence 

 longer and more tawny.

 Three examples.
