ICHNEUMON-FLIES, PART 2 1 EPHIALTINAE 369 



tifying character. The holotype and two paratype females are the 

 only specimens of this species known to me. 



Holotype female: Body, 7.8 mm.; ovipositor sheaths, about 4 mm. 



Head: Polished, finely punctate, face a little more coarsely so; eyes 

 slightly convergent anteriorly; malar space about one-half as long as 

 basal width of mandible; face one and one-half times as wide as long; 

 antenna with 31 segments. 



Thorax: Fully twice as long as deep; mesoscutum finely punctate, 

 polished; sternaulus evident only anteriorly; mesopleurum more finely 

 and sparsely punctate, punctures becoming obsolete posteriorly; dorsal 

 face of propodeum a little longer than posterior face; areola a little 

 longer than wide; pubescence of propodeum sparse and becoming 

 longer laterally, center of areola lacking pubescence; wings hyaline and 

 slightly inf innate, veins dark, stigma black except for white spot at 

 extreme base. Hind legs with tibia about as long as femur and tro- 

 chanters combined. (All of left front leg except coxa and first tro- 

 chanter missing in type specimen.) 



Abdomen: Polished, about one and one-half times as long as head 

 and thorax combined ; first three tergites more or less granular, remain- 

 ing tergites very finely coriaceous; pubescence of tergites laterally 

 more sparse and only slightly longer; ovipositor sheaths about three- 

 fourths length of abdomen; ovipositor very slender and apical fourth 

 attenuated to a fine point. 



Color: Black, except clypeus, middle and hind coxae, basal two- 

 thirds of hind femora, middle femora (dusky apically) reddish; apices 

 of front coxae, apices and inner face of front first trochanters, inner 

 face of front femora, front tibiae, apical spots on outer face of front 

 femora, inner and outer faces of middle femora, outer and front faces 

 of middle tibiae to within % distance to apex, anterior half of 

 tegula and spot on pronotum just in front of tegula, mandibles except 

 teeth, malar space, and base of hind wing, whitish; maxillary and 

 labial palpi brownish; pale area on inner face of hind tibiae barely 

 visible. 



Variations: Antenna 31 to 32 segmented; extent of white on inner 

 face of hind tibia varying from the barely visible streak of type speci- 

 men and from a spot near center, to a central streak covering nearly 

 half of length to apex; punctation of face varying in degree. The 

 clypeus of the type specimen is bent inward apically — probably an 

 abnormality. 



Described from holotype female in the U. S. National Museum 

 Collection under Type No. 21395.
