the ElateriJaj of Japan. 35 



and second stria very fine, all punctate-striate, interstices 

 bscurely and thinly punctulate ; the antennae infuscate, 

 second and third joints nearly equal, the second is somewhat 

 lon^ for this genus ; the legs intuscatc, tarsi paler. 

 llab. Nikko, in June. Two examples. 



Elater scuteUaris, sp. n. 



Atcr, nitidus, longius nigro-pubcsceus ; thoracc subtiliter puuctu- 

 lato ; elytris rufis, apice minute infiiscatis, puuctato-striatis, 

 interstitiis punctulatis : scutello postice acuminato, antico per- 

 depresso ; antenuis pedibusque uigris. 



L. 11 miU. 



Densely black, with rather long black pubescence ; the 

 head somewhat densely and little coarsely punctured, carina 

 well marked and semicircular,- the thorax opalescent, narrowest 

 anteriorly, gradually widening to base, very finely, evenly, 

 and rather thinly punctured on the disk, at anterior and poste- 

 rior angles punctured like the head ; the scutellum is nearly 

 vertical and distinctly acuminate behind ; the elytra reddish 

 brown, apices minutely infuscate, evenly punctate-striate, 

 interstices slightly concave and feebly punctulate; the antenuce 

 and legs black, tarsi pitchy. 



The almost perpendicular position of the scutellum in this 

 species distinguishes it from all the others in this series. 



Hab. Chiuzenji, Niohozan, and Sapporo. Eight examples. 



Elater atnu, sp. u. 



Ater, nitidus, nigro-pubescens ; thorace vix dense punctulato ; 



elytris rufis, striis internis leviter impressis, interstitiis tcnuiter 



transverso-rugosis ; antennis pedibusque nigris. 

 L. 11 mill. 



Densely black, with black pubescence; the head rather 

 coarsely and rather densely punctured, carina well-marked 

 and semicircular ; the thorax densely black, not opalescent, 

 somewhat wide, convex on disk, arched at the sides, punc- 

 tured laterally like the head, disk-punctures finer and less 

 close, but not densely set, hind angles between the carina and 

 outer edge thickly, coarsely, and somewhat rugosely punctate ; 

 the scutellum punctate, somewhat wide and obtusely acumi- 

 nate behind ; the elytra red (not very bright), interstices 

 rather broad and flat, feebly and transversely rugose, striee 

 1-3 fine and lightly impressed, scarcely punctate, external 

 strige deeper and distinctly punctate ; the antennge densely 

 black, third joint obconical and longer than the second, 

 dilated joints relatively robust ; the legs black, tarsi pitchy.
