Elater pauxillus, sp. n. 



Niger, nitidus, griseo-pubescens ; capite distincte punctulato ; elytris 



punctato-striatis ; antennis pedibusque rufis. 

 L. 5 miU. 



Black, shining, with a greyish pubescence ; the head 

 clearly but not densely punctulate, eyes a little prominent ; 

 the thorax widest near the middle, disk more finely punctulate 

 than the head ; the scutellum obscurely punctulate, obtuse 

 behind ; the elytra, striae punctate-striate, striae 1-3 very 

 fine, outside strise more deeply impressed, interstices flat and 

 finely punctulate ; the antennas red, not serrate, second joint 

 stouter and a little shorter than the third ; the legs also 

 w^holly red. 



This is the smallest species known from Japan. The 

 head is smaller than that of the last species and the eyes 

 more prominent. 



Hah. Nikko. One example. 



Elater gracUipes^ sp. n. 



Elongatus, angustatus, infuscatus, fulvo-pubescens ; thorace sub- 

 tilissime punctato ; elytris parallelis, angulis humerali obscure 

 brunneis.

 tured ; the thorax little narrowed anteriorly from the middle, 

 posterior carina feeble, punctuation scarcely visible on the 

 disk, more apparent at the sides and angles ; the scutellum 

 obsoletely punctured, obtuse behind; the elytra long and 

 parallel at tlic sides, faintly punctate-striate, sutural stria 

 finest, interstices flat, rugose, and rather wide, humeral angle

 tion feeble, articulation somewhat lax, third joint less robust,
