separated by the structural differences in the stigmal vein. In 

 Howard's (1908) table of the species of the genus, it would drop in 

 near siiiiilis (Masi) or kochclci Howard, differing from the latter in 

 its black head, more clavate antenn?e, naked area of the fore wings 

 and details of antennal structures, as well as in the perfectly hyaline 

 wings and the contrasting coloration of the scutellum with that of the 

 rest of the mesonotum. An apparent typographical error is present 

 in the first line of the table referred to (Howard, 1908, p. 281), 

 namely, the words " pointed marginal vein " being printed instead 

 of " pointed postmarginal vein." The error, however, is readily 

 detected because of the fact that the marginal vein in the whole sub- 

 family is usually very long and in the genus Prospaltella is as long as 

 is normal.

Girault, 1909a. pp. 27-28, fig. 2. 



This species recently described from several female specimens 

 captured at Urbana, 111., in July, 1908, proved to be common at 

 Centralia, 111., during the latter part of August and the first part of 

 September, 1909, both sexes being captured, the female in numbers. 

 The color of its body is really shining black in nature, appearing 

 greyish black in balsam mounts. Otherwise its description is correct 

 as given, excepting that the club joint is not narrowed as shown in 

 the figure (Girault, 19090, fig. 2) and with the exception of the 

 shape of the abdomen which is ovate in lateral aspect in balsam 

 mounts but in the dorsal aspect as has been described. The dilata- 

 tion on the caudal margin of the fore wings near base is a regular 

 sloping convexity, not acute or emarginate at any place on its margin ; 

 the cox?e are concolorous with the clay yellow legs; the eyes are 

 reniform, very dark garnet, their surface coarse; abdomen smooth
