Family LXIII. PYROCHROID.E. 

 THE FIRE-COLORED BEETLES. 



A small family of moderate sized, broad depressed beetles hav- 

 ing the elytra rather soft in texture, usually widened behind the 

 middle and remarkable for their relative size. The head is almost 

 horizontal and constricted behind the eyes into a rather slender 

 neck, both head and thorax being much narrower than the elytra. 

 Most of our species are conspicuous for the rufous thorax, which 

 contrasts with the black elytra and for the prominent antenna? 

 which are serrate or subpectinate in the female and usually with
