AET. 14 ICHNEUMON-FLIES OF GENUS POLYCYRTUS CUSHMAN 35 



of Natural Sciences of Philadelphia to examine the type series. Miss 

 Sandhouse reported that the lectotype and paratypes 2-7 and 11-12 

 are one species and agree with the description, while paratypes 8-10 

 disagree with the description. 



Through the kindness of Mr. E. T. Cresson, jr., I have borrowed 

 the three discordant paratypes and find that not only are they not 

 copiosus but that only No. 8, a female, is the same as the National 

 Museum specimen, while Nos. 9 and 10, both males, represent a third 

 species, which belongs to the subgenus Cryptanuridimor'pha. The 

 two females I have described above as Polycyrtus {Polycyrtus) con- 

 fitsus. Because of the lack of the female I do not describe the third 

 species. 



P. copiosios differs from the foregoing description of confusus as 

 follows : 



Female. — Vertex in front view slightly concave; frons evently 

 concave, without median elevation or grooves, but with a small tuber- 

 cle at base of horn ; eyes more strongly convergent below ; malar space 

 distinctly longer than basal' width of mandible, strongly constricted, 

 mouth distinctly narrower than narrowest width of face; occipital 

 carina weakly convergent above with posterior margin of eye, weakly 

 prominent below and separated from hypostomal carina by a shal- 

 low furrow ; diameter of lateral ocellus barely two-thirds as long as 

 ocell-ocular line and not nearly twice postocellar line; first joint of 

 flagellum nearly ten times as long as thick. Scutellum high; pre- 

 pectal carina complete; metapleurum obliquely rugose; propodeal 

 spiracles narrowly oval, apophyses very long, slender and curved, 

 much nearer to carina than to apex; inner hind calcarium less than 

 half as long as basitarsus ; areolet of normal size and form with re- 

 currai\t strongly antefurcal. 



Face white except medially and in clypeal groove, where it is 

 brown ; posterior orbits with a large, elongate white spot ; scutellum 

 discally black. 



Male. — Face entirely white ; annulus beginning on eighth flagellar 

 joint; all tergites beyond first blackish at base. Otherwise much 

 like female. 



The above comparison with confusus is based on one specimen of 

 each sex from Mexico in the United States National Museum, the 

 female a metatype. 



35. POLYCYRTUS (POLYCYRTUS) COLLICULATUS, new species 



Distinct from all other species known to me in the arrangement of 

 color on the thorax and the form of the propodeum. 



Female. — Length 14 mm. 



Vertex and frons concave, horn large, conical and without either 

 tubercle or ridges above its base ; eyes slightly convergent below, com-
