10 Randall's New Species of 
Body somewhat dilated: head black: antenne light 
piceous: sub-convex, broadest at base, punctured, a 
little hairy, without any median furrow; margin gradu- 
ally curved toward the anterior angles, which are no 
wider than the head; posterior angles sub-acute and 
nearly straight: scufel ovate, black, striate, punctured: 
elytra, sub-basal and humeral regions rufo-sanguineous : 
body beneath black, punctured : feet piceous. 
Length from three tenths to four tenths of an inch. 
Appears allied to the bimaculdtus of Europe, and to 
the geminatus of Say. Not very frequent. 
12. ELATER SEMI-CINCTUS. 
E. corpore sub-dilatato, sericeo ; antennis serratis; thorace nigro, 
sub-convexo, punctulato, leviter ad basim impresso, angulis posticis 
sub-acutis ; scutello nigro; elytris nigris, striatis, punctulatis, basi 
margineque superiori sanguineis ; apice obtuso. 
Body considerably dilated: antenne black, third 
joint much smaller than the fourth: head and thorax 
black, punctured, polished ; the latter somewhat convex, 
gradually narrowing before, somewhat sericeous, median 
furrow obsolete or indented at base; posterior angles 
sub-acute, nearly in a line with the margin, and some- 
times terminated by a bristle: scutel black: elytra black, 
with deeply punctured strie ; interstitial spaces only 
slightly convex, deeply punctured ; base with a san- 
guineous band, curving over the humerus, and passing a 
little downwards upon the margin; apex rather obtuse : 
body beneath black, punctured: feet somewhat piceous. 
Length rather more than nine twentieths of an inch ; 
rare. 
It seems most nearly allied to the E. discoideus of 
Fabr. i
