No. 2326. THREE TRIBES OF ICHNEUMONINAE—CVSHMAN. 25 



has the body-color of the type, but the legs very contrastingly colored, 

 the stramineous being replaced by white and more extensive and the 

 testaceous brighter. 



In size the specimens are very uniform, the smallest male being 

 7 mm. and the largest female 8 mm. long. 



The above enumerated five specimens constitute the entire repre- 

 sentation of the species in the United States National Museum, the 

 distribution being Santa Cruz Mountains, and Los Angeles, Cali- 

 fornia, and Lawrence, Kansas. 



The type was reared from Epeira strix or sclopetaria. The cocoon 

 is 7 mm. long by 3 mm. broad, very loosely woven and netlike, and 

 pinkish brown. 



POLYSPHINCTA (POLYSPHINCTA) ELONGATA, new species. 



Very closely allied to hurgessi Cresson, from which species it differs 

 in its somewhat more slender form, in lacldng the median longitudinal 

 carinae on the propodeum, and in the distinctly longer ovipositor. 



Female. — Length 9.5 mm,, antennae (broken), ovipositor 3 mm. 



Polished with a few weak punctures on mesosternum, laterally on 

 propodeum, and in the impressions of the tergites, especially toward 

 the apex of the abdomen; clypeus very broad and short with its 

 apical rim so strongly reflexed as to give the appearance of truncation 

 (this occurs to some extent in some specimens of hurgessi Cresson, 

 while in others it is not apparent) ; face distinctly longer than wide, 

 eyes not convergent below antennae, weakly emarginate; ocell-ocular 

 line shorter than postocellar line, diameter of lateral ocellus equal 

 to the latter; temples flat; mesonotum highly polished, impuncate, 

 and without pubescense, notauli weak posteriorly; propodeum with 

 a deep longitudinal furrow in basal middle, but without carinae; first 

 tergite considerably longer than wide at apex, its sides nearly straight 

 and divergent, its carinae obsolete beyond the summit, not flattened 

 dorsally; lateral tubercles strong on tergites 2-6, the apical impres- 

 sions broad and interrupted in the middle, exserted portion of ovi- 

 positor very slightly decurved and very acute at apex, about half as 

 long as abdomen; wings with transverse cubitus two-thirds as long 

 as second abscissa of cubitus, nervellus distinctly broken not far 

 below the middle; hind basitarsus barely as long as next two joints 

 together. 



Black; scutellum, postscutellum, and spots at bases of middle and 

 hind legs piceous; apical part of clypeus and mandibles brown; palpi 

 white; antennae blackish, somewhat paler beneath at base, espe- 

 cially at apex of scape; wing bases, tegulae and posterior angle of 

 pronotum wliite; legs testaceous with the following pattern; front 

 coxae apically, front trochanters, femora apically, apical segments 

 of hind and middle trochanters and their basal joints at apex, all 

 tibiae above, front tarsi, hind and middle tarsi above toward the
