OF WASHINGTON, VOLUME XVII, 1915 139 



Black with the coxae and basal segment of posterior trochanters black ; 

 mandibles, palpi, trochanters, except as noted above, and teguhi', whitish; 

 posterior tibiae white with the apex and an annulus near the base black, 

 the two connected beneath by a reddish stripe; hind basitarsus white with 

 apex black; middle tibiae and tarsi with same arrangement of color as in 

 hind legs but the black replaced by fuscous; all femora and front tibise 

 of varying shades of rufous, the hind femora darkest and front tibiae 

 lightest. 



Male. Differs from the female largely in the more contrasting colors of 

 the legs, the lack of annulation on the middle tibiae, and in having the 

 basal middle area of the propodeum reduced to a triangle connected with 

 the areola by a single short carina. 



Host: Phthorimaea operculella. 



Type locality: Pasadena, Calif. 



Type: Cat. No. 19156, U. S. N. M. 



Described from 4 females and 6 males reared from the above 

 host by J. E. Graf in November, 1914, under Chittenden No. 

 2230 0? . 



This species varies in the following manner: one of the females 

 has the sides of the abdomen beyond the second tergite largely 

 red; the size and form of the basal middle propodeal ares varies 

 in more or less reduction from the type; and some of the males 

 show a rather distinct color pattern on the middle tibiae. 



GENUS XENOSCHESIS Foerster. 



The only species originally included in this genus and there- 

 fore the genotype is Exetastes fulvipes Grav., so placed by Jemil- 

 ler (Ber. Ver. Augsberg, vol. 31, 1894, p. 147). The same species 

 was selected by Kriechbaumer as the type of his genus Glypto- 

 centrus and by Viereck as the type of Polycinetis (Foerster) Dalla 

 Torre and Polydnetus Thomson. The genotype of Polycinetis 

 Foerster as fixed by Woldstedt is Notopygus resplendens Holm- 

 gren. This species is shared as a genotype by Prosmorus Foer- 

 ster, by fixation of Thomson, and, through its variety polita 

 (Foerster) Kriechb., by Eriglcea Foerster, by fixation of Viereck. 

 All of the above was pointed out by Viereck (U. S. N. M., Bui. 83). 



Examination of specimens of the genotypes, fulvipes as deter- 

 mined by Schmiedeknecht and resplendens as determined by 

 Roman, convinces me that they are congeneric. Therefore 

 Polycinetis Foerster, Polydnetus Thomson, Glyptocentrus Kriech- 

 baumer, Prosmorus Foerster. and Eriglcea Foerster are all syno- 

 nyms of Xenoschesis Foerster. 



As to the position of the genus, I prefer to place it with the 

 Banchini, rather than with the Mesoleptini. It should be noted
