Buprestls, Trachys, and Elater. 257 



This species is more thickly covered with hair than usual. 

 I am unacquainted with the griseus, Beauv. : but if his figure 

 is even a tolerable representation, our insect is very distinct, 

 his description is too short and unessential to give any as- 

 sistance. 



7. E. attenuatus. Reddish ; elytra lanceolate, black at tip. 

 Elater attenuatus, Melsh. Catal. 



Description. Body brownish, sanguineous, with short hairs : 

 head blackish, without any transverse elevated line : antenna 

 deeply serrated, blackish rufous ; third joint very short, 

 not longer than the second ; thorax with an impressed ab- 

 breviated longitudinal line on the posterior margin ; ante- 

 rior margin not wider than the head ; posterior spines 

 rather long and acute : scutel oval : elytra with the striae 

 obsolete, gradually attenuated to the tip, which is lanceo- 

 late, acute ; region of the scutel deeply indented ; tip black, 

 occupying nearly one-third of the surface, and terminating 

 anteriorly obliquely. 



Length nearly four-fifths of an inch. 



This species seems to be rare. 



8. E. mridipilis. Depressed, black, covered with short 

 blackish-green hair. 



Description. Body dilated, somewhat depressed, black, 

 with a greenish tinge occasioned by short hair of that 

 colour : head concave, the transverse line between the an- 

 tennae obtuse : antenna deeply serrated ; third joint very 

 short, equal to the second : thorax depressed, longer than 

 broad ; sides rectilinear and parallel ; anterior angles 

 acute, wider than the head ; posterior angles not spiniform : 

 scutel subtriangular : elytra with impressed, punctured 

 stria?.
