a distinct sub-family; the characters, however, are marked 
enough to separate a genus. 
The Anechurine are distinguished by the sub-conical 
4th and 5th segments of the antennz, by the often short 
and broad pronotum, by the broad and flattened elytra, 
often with sharp humeral carine, by often short, and broad, 
pygidium, and by long and slender legs; also by the 
branches of the forceps in the male, which are remote 
at the base, not depressed nor thickened; they are 
often bent and bowed upwards and downwards, in and 
out, in a very characteristic manner. The last dorsal 
segment of the abdomen is shorter and narrower than the 
preceding segments, which are usually somewhat dilated ; 
the last segment is also short, and often armed with 
tubercles pointing in different directions. 
The members of this sub-family usually occur in 
mountainous countries; with the exception of A. elongata, 
a little known species recorded from Cuba, they appear to 
be confined to the Old World.
