Lnmpijrtx jtt/rnU^, Mclsh. Catal. 



Body oblong : head blackish, more or less tinged with rufous; 

 mouth paler ; antennse brown : thorax regularly arcuated before 

 and on each side ; briglit rosaceous, with a black central spot 

 and impressed line ; anterior and lateral margins pale yellowish ; 

 posterior edge very slightly arcuated, which extends equally 

 from one angle to the other : elytra pale brown, with a narrow 

 exterior, sutural and terminal margin. 



Length nearly three-tenths of an inch. 



This is our very abundant *' Fire-fly," and is familiar to every 

 inhabitant of this country. It is very like the centrata nob., 

 but is much smaller and of a much paler color. With the late 

 Mr. Melsheimer, I have always hitherto considered this species 

 to be the [165] pyraUa of authors ; but on a careful comparison 

 with their descriptions, and particularly that of Olivier and his 

 figure, 1 have, after much hesitation, eonduded that it is dis- 

 tinct from that species. The j)i/ralk is described to be equal in 

 size to the spfrndiduht and noctifwa, but our species is smaller ; 

 my chief reliance, liowever, is on the figure given by Olivier, 

 which is beyond all doubt that of a widely different species from 

 the present. 



The female differs from the male in having the elytra imper- 

 fect, being not more than one-third the length of the abdomen : 

 they are, however, margined like those of the male.
