punctate, interstices punctulato, second and fourth widest, all 

 rather flat; the antcnnoe — three basal joints reddish brown, 

 otiiers infuscate, third joint longer than the second ; tlie legs 

 reddish brown. 



This species should be placed next to E. hypogastricus, 

 Cand., but the head and thorax arc broader, with much finer 

 punctures, thorax not opalescent, the elytra! interstices rather 

 flatter and distinctly wider, and the form of the insect 

 generally more parallel. In E, hypogastricus, Cand., the 

 scutellum is relatively small and acuminate behind.

Elater vestitus, sp. n. 



Parum nigcr, nitidus, densissime fulvo-pubescens ; capita dense 



punctato ; antennis pedibusque obscure rufis. 

 L. Hi mill. 



Blackish, shining, very densely covered with a tawny pubes- 

 cence, especially on the elytra; the head densely and rather 

 coarsely punctured ; the thorax narrowest anteriorly, feebly 

 widening at the middle, punctured like the head in the female, 

 punctures less dense in the male, median channel faint and evan- 

 escent in front ; the scutellum obscurely punctured, obtusely 

 acuminate behind ; the elytra punctatc-striate, two stride next 

 the suture somewhat fine, interstices punctulate and feebly 

 convex ; the antennae rather dark reddish brown, third joint 

 a little longer than the second ; the legs clear reddish brown, 

 lighter in colour than the antennae. 



In looking at this species in certain lights the sculpture 

 and striffi are entirely obscured by the pubescence. This 

 remark does not of course apply to abraded examples, of 

 which I have several. 



Hab. Miyanoshita, Hakone, Hitoyoshi, and Yuyama. 

 Apparently common. 



Elater tenuistriatus, sp. n. 



Niger, nitidus, infuscato-pubescens ; thorace subtiliter punctulato ; 



elytris striis internis tenuiter impressis ; antennis pedibusque 



nigris, tarsis brunneis. 

 L. 10-11 mill. 



Black, shining, with dusky pubescence ; the head some- 

 what densely punctate ; the thorax widens out a little behind 

 the middle, at the sides narrowly punctured like the head, on 

 the disk very finely and sparingly punctulate ; the scutellum 

 feebly punctulate, a little obtusely acuminate ; the elytra.
