 The Necrophori are distinguished by the form of 

 the antennae, which are very little longer than the 

 head, with the four last joints forming a perfoliate 

 club, as represented in the following figure. The 

 mandibles are without teeth, and 

 the elytra are of an oblong-quad- 

 rate form, leaving three or four of 

 the segments of the abdomen un- 

 covered. The species, amounting 

 to near thirty, are confined, as far

 northern parts of America. They are almost in- 

 variably of a brownish-black colour, frequently va- 

 riegated with spots and bands of orange yellow. 

 Seven different kinds occur in Britain, one of which 

 is represented on the accompanying plate.
