Type. — Derniere Provancher collection. Public Museum, Quebec. 

 Polysphincta rufopectus Provancher, Nat. Can., vol. 7, 1875, p. 140, female. 



Type. — Probably in Public Museum, Quebec, and labeled Polysphincta limata, 



since Provancher himself indicated the synonymy. 



Discussion based on types and other material. 



Distinct from koebelei Howard and elongata Cushman in its trans- 

 versely roughened propodeum and the presence of the longitudinal 

 carinae, from the former by its largely or entirely black mesothorax, 

 and from the latter by its relatively shorter ovipositor and stouter 

 form. 



CljT^eus, ocelli, and ocellar lines as in Jcoehelei; sculpture of the 

 body as in the latter species except that the propodeal carinae are 

 present, the propodeum is more or less transversely rugulose, and 

 the mesopleural furrow is minutely foveolate; entire ovipositor 

 about three-fifths as long as abdomen; hind tibiae marked much as 

 in I'oehelei, but more broadly blackish at apex and there is usually a 

 more or less distinct subbasal dark annulus (in the type of hruneti 

 the latter is entirely lacking); first three joints of hind tarsi white 

 at base; color-pattern rather distinctly repeated on middle tibiae. 



Except for slight differences in size, color, and sculpture of pro- 

 podeum all the female specimens of this species are very much alike. 

 The type of rufopectus is said to have the thoracic venter red. The 

 same is true of two females in the Academy of Natural Sciences of 

 Philadelphia and one in the United States National Museum, and of 

 the male type of hurgessi. In some other specimens the area im- 

 mediately at the base of the middle coxae is somewhat reddish. The 

 male differs from the female principally in its much more strongly 

 sculptured, nearly opaque abdomen. 



Apparently this species has never been reared. It appears to be 

 largely northern in its range. Cresson's two types are from Mass- 

 achusetts, Provancher's two types from Canada, of the seven speci- 

 mens in the National Museum three are from Canada, one each from 

 St. John, New Brunswick, Oswego, New York, and Terra Alta, West
