K0.221C. NEW REARED ICHNEUMON-FLIES— CUSHMAN. 461 



Male. — Length, 5.5 mm.; antennae, 3 mm. 



Very like the female, the principal difference consisting in the 

 relatively narrower propodeal areas and tergites, the areola being 

 distinctly longer than wide and the first tergite less than three times 

 as wide at apex as at base, the slightly paler legs, and entirely hyaline 

 wings. 



Host. — Ametastegia glabrata (Fall6n). 



Type-localitg. — Wenatchee, Washington. 



Type.—Csit. No. 20774, U.S.N.M. 



The type series consists of five females and one male, reared by 

 Mr. E. J. Newcomer, of the Bureau of Entomology, during April, 

 1915 (Quaintance No. 11422), and May, 1916 (Quaintance Nos. 

 14017 and 14021). The paratypes, all females, exhibit variation 

 in size dowii to 4.5 mm., with the legs paler, the ovipositor relatively 

 longer, and the sculpture of head and thorax weaker. 



AENOPLEX CARPOCAPSAE Cushman. 



Since the publication of this species several more specimens have 

 been reared, including a number of males. All but one are from the 

 type-locality and type host, the exception being a male reared 

 March 31, 1913, at Dewitt, Georgia, from Enarmonia caryana, under 

 Quaintance No. 9178. 



The male differs from the female principally in the relatively 

 narrower propodeal areas and abdomen, in having the mandibles, 

 coxae, and trochanters paler, and all but one have a distinct pale 

 spot on the scape. The abdomen is in every case entirely black, 

 except for the narrow whitish margins of the apical tergites. 



Genus SPILOCRYPTUS Thorns. 



SPILOCRYPTUS POLYCHROSIDIS, new species. 



Female. — Length, 5.5 mm. ; antennae, 4 mm. ; ovipositor, 0.8 mm. 



Head polished, face and lower orbits granularly opaque ; vertex 

 declivous behind the ocelli, the occipital carina subangulate medially; 

 temples strongly rounded; clypcus prominent, with a few rather long 

 hairs; cheeks flat; malar space about as long as basal width of man- 

 dibles; antennae slender, flagellum slightly thicker at apex than at 

 base, first joint about four times as long as thick, distinctly longer 

 than the second. Thorax opaque, minutely punctate above and dis- 

 tinctly striate laterally ; notauli distinct, meeting before the posterior 

 margin; propodeum opaque, declivous behind, with two complete 

 transverse carinae; legs slender; wings large, areolet rather small, 

 its sides convergent, radial cell short, reaching barely half way 

 to apex of wing, ncrvellus postfurcal, broken below the middle. 

 Abdomen about a third longer than head and thorax, broadest at 

 apex of third tergite, minutely densely punctate, polished and im-
