Reduviidae. 



Oxk of the obvious characters of this family is the constriction behind the head, which 

 makes it appear to be prolonged or extended behind into a narrow neck. The eyes are each 

 aoooB^panisd by a single ocellus. The antenna? are sometimes prolonged and slender; in 

 other oases, short. The thorax is often armed with a lateral spine. The legs are long, and 

 the forelegs rather stouter and raptorial : tarsi three, and sometimes quite minute.

 with two lateral spines, and in front transversely ridged : wings large : legs long 

 and hairy.
