NO. 1202. GENERA OF TSE ENCYETINJE—ASRMEAD. 397 



It comprises a group whicli appears to be Lyperpnrasitic on Ichneumon 

 flies belonging to the subfamily Ophionince; ;it least such appears to 

 be the case with two of the North American species, and I should not 

 be surprised to find all the species, falling in the genus, hyperparasitic. 

 The stigmal veiu is never longer than the marginal and postmarginal 

 united, most frequently distinctly shorter ; the axillae usually meet at 

 their inner basal angle; the autennie are rather short, the club much 

 enlarged, as long, longer, or nearly as long as the funicle, and from two 

 to three or more times wider than the last joint of the funicle; the 

 funicle is 6-jointed, short, the joints transverse wider than long, or at 

 least the 3 or 4 terminal joints, or the first 3 or 4 joints are moniliform, 

 while the abdomen is ovate or pointed ovate, but not longer than the 

 head and thorax united, usually somewhat shorter, the ovipositor not 

 or only slightly extending beyond the tip of the abdomen.

69. SYRPHOPHAGUS Abhmead, ne^v genus. 

 (Type, Encyrtus inesograptw Ashmead.) 



In wing venation this genus comes nearest to Epiencyrtus^ but is 

 easily separated, in the female sex, by the marked difference in the 

 autennte brought out in my table.
