 but not closely punctured ; the thorax widens out a little 

 before the posterior angles, punctured narrowly at the sides 

 like the head, disk lightly and sparingly punctulate ; the 

 scutellum punctured, obtusely acuminate behind ; the elytra 

 punctate-striate, sutural stria finest, interstices subrnffose, 

 punctulate; the antennae, articulations less lax than those 

 of E. ienuisfriatus, basal joint red, second and third nearly 

 equal, piceous, the others infuscate ; the legs clear red.

 Elater carhunculus, Lew. Eut. Month. Mag. 1879, p. 156. 



Ater, nitidns, longius nigro- vel cinereo-pubescens ; antennis pcdi- 

 busque concoloribus ; capita punctato ; thorace disco subtilissime 

 punctulato ; olytris punctato-striatis, interstitiis a basi latissimis. 



L. 7 mill. 



Densely black, shining, with blackish or asliy pubescence ; 

 the head clearly but not very densely punctured ; the thorax, 

 disk very lightly punctulate, sides more distinctly, but the 

 punctures arc not so large as those of the head ; the elytra 

 punctate-striate, strife clearly but not deeply impressed, inter- 

 stices widest at the base ; the anteiina> rather long, especially 

 in the male, with articulations .>^omewhat lax, entirely black, 

 second joint very small, third widens out triangularly and is 

 scarcely smaller than the fourth. This la.'^t character seems 

 to be a transitional one between Elater and Ischnodcs.
