754 REPORT OF NEW JERSEY STATE MUSEUM. 

 Family DOUCHOPODIDyE. 



Small, usually shining green, sometimes black or yellow flies, with 

 short antennae, plump body and comparatively long legs, which are often 

 contrasting yellow or brown. The tarsi or feet are unusually long, whence 

 they are called "long-footed flies," and in the male the anterior pair are 

 often flattened or otherwise modified. In the same sex the abdomen is 

 frequently furnished with curiously complex claspers, which are bent 

 down beneath the body. In the female there is usually a pointed, flat 

 ovipositor. They are predatory in habit, feeding chiefly upon smaller 

 flies. The larvse are long, slender, cylindrical and feed on decaying 

 vegetation.
