244. Heterospihcs terminalis, n. sp. 



$ . Length 2-2"2 mm. ; ovipositor much shorter than the abdomen, 

 sometimes scarcely half as long. Black ; antenme basally, collar, 

 more or less of second abdominal segment, with sometimes the first 

 at the apex or entirely and the terminal two or three segments ferru- 

 ginous or testaceous ; antennfe dusky or brownish towards apex ; 

 palpi long, white ; legs flavo-testaceou?, the coxa? and trochanters 

 sometimes whitish. The head and thorax anteriorly are polished, 

 impunctate, the parapsidal furrows distinct, the metathorax rugulose, 

 distinctly areolated, the areola lozengoidal. Wings hyaline, the 

 stigma and veins brown, the first transverse cubitus incomplete, 

 evanescent at base but if complete would be interstitial with the 

 recurrent nervure. Abdomen oblong, as long or nearly as long as 

 the head and thorax united, the first segment a little shorter than 

 the second, the first entirely and the second for two-thirds its length 

 longitudinally striated, rest of abdomen smooth, polished. 



The head in the $ varies from a brown to a black and the 

 abdomen at tip is most frequently black, while the hind wings have 

 a large stigma, otherwise in sculpture and size they are quite 

 similar.
