ABT. 4. NEW SPECIES OF ICHNEUMON-FLIES — CUSHMAN. 11 



dorsal end of the prepectal carina, in addition to differing by the 

 characters mentioned above. 



From tlve male it differs in having the eyes larger and nearly par- 

 allel; the face and malar space narrower; the face medially black 

 with a large yellow spot below each antenna; the thorax much less 

 extensively yellow with the mesosternum entirely black; the meta- 

 pleiirum and sides of propodeiim partly rufous; the legs generally 

 darker testaceous, this color including the hind coxae, which lack 

 the dorsal black stripe; and the antennae less distinctly bicolored, 

 though distinctly paler before the apex and below. 



Another female specimen from Montana which appears not to 

 differ structurally has the basal three tergites rufous instead of black 

 and the fourth partly so. 



Phytodietus gracilicornis Cresson, from Mexico, is related in 

 structure and color to 'pulcherrimus. 



Subfamily Ophioninae. 



TRIBE CAMPOPLEGINI. 

 HYPOSOTER RUBIGINOSUS, new species. 



Remarkable chiefly because of its entirely ferruginous body, with 

 only the head black. In color most like {Limneria) Hyj)osoter rufa 

 (Ashmead), from which the male of the present species is at once 

 distinguished by its black face and whitish clypeus. 



Female. — Length 8 mm. ; antennae 7 mm. 



Head strongly transverse with temples and postvertex strongly 

 sloping, opaque shagreened ; face densely punctate and densely gray 

 pubescent, slightly narrowing below; eyes slightly emarginate; 

 clypeus broadly subtruncate and with a narrow reflexed margin; 

 malar space half basal width of mandible; diameter of lateral ocellus 

 shorter than postocellar line and longer than ocell-ocular line ; flagel- 

 lum rather stout, tapering toward apex. Thorax opaque shagreened 

 throughout with more or less distinct punctuation on mesoscutum, 

 pleura, and sternum; notauli obsolete, rugulose; propodeum nearly 

 completely areolated, the costulae present and the areola and petiolar 

 area separated; spiracles broadly oval; petiolar area transversely 

 rugulose, propodeum otherwise granularly opaque; legs moderately 

 stout; hind calcaria two-thirds as long as basitarsus, apical tarsal 

 joint slightly longer than fourth, claws large and strongly pectinate ; 

 tibiae and tarsi spinose; stigma and radial cell narrow lanceolate, 

 radius barely angulate; areolet petiolate, recurrent beyond middle; 

 nervulus postf ureal; subdiscoideus slightly above middle of post- 

 nervulus ; lower outer angle of second discoidal cell acute ; abscissula 

 slightly longer than recurrentella ; nervellus vertical, unbroken. 

 Abdomen granularly opaque, stout, weakly compressed toward apex, 

 < he compression beginning beyond base of third segment ; first tergite
