ART. 21. NEW SPECIES OF ICHNEUMON-FLIES CUSHMAN. 17 



scape yellow, but Morley does not give the color of the tegulae of 

 mexicana, while in texana they are black. 



HYMENOPHARSALIA SCHWARZI, new species. 



At once distinguishable from any of the four following species by 

 the unswollen hind basitarsus, the weakly sculptured vertex and lat- 

 eral lobes of mesoscutum. and from all but texanus and foutsi by the 

 entirely yellow face. 



Female. — Length, 11 mm. ; antennae, 4 mm. ; front wing, 4 mm. 



Head from above slightly wider than thorax; temples flat, about 

 one-third as long as the shortest diameter of ej'e, densely clothed with 

 long white pile; occipital carina nearly touching ocelli, obsolete in 

 middle; secondary carina of occiput so strong that when head is 

 viewed from above it appears bidentate on each side, the carina origi- 

 nating on each side very close to base of mandibles and apparently 

 complete above cervical foramen; occiput polished and impunctate 

 medially above ; vertex smooth and subpolished with a few punctures 

 between the ocelli ; f rons densely punctate in middle, smooth at sides ; 

 face polished but so densely covered with white pile that surface is 

 obscured, scarcely half as wide below as at antennae ; inner margins 

 of eyes sinuately emarginate opposite antennae ; malar space very 

 short ; clypeus as long as wide, its apex broadly subtruncate, mandible 

 with a distinct tooth on lower margin at base of lower tooth, upper 

 tooth hardly twice as long as lower; antennae longer than head and 

 thorax, flagellum filiform, 23-jointed, first joint as long as second and 

 third combined, middle joints more than twice as long as thick; fur- 

 row of pronotum sharply limited behind by a carina, foveolate in 

 front and below, punctate behind, polished in middle; mesoscutum 

 polished at sides, prescutum rugulose-punctate, notauli irregularly 

 reticulate, lateral margins foveolate; mesopleural furrow transversely 

 rugose below, polished above, with anterior and posterior margins 

 more or less distinctly foveolate ; mesosternum with a sharply defined 

 longitudinal, glabrous, polished spot on each side; propodeum nar- 

 row, its sides not bulging, median furrow and lateral carinae dis- 

 tinct, reticulation almost obscured by pubescence, "•neck" hardly 

 reaching to middle of hind coxae ; radial cell very small, shorter than 

 apical abscissa of metacarpus; intercubitus distinct; hind basitarsus 

 slender ; hind coxae in their greatest thickness hardly a third as thick 

 as long ; abdomen opaque, very densely pubescent ; ovipositor sheath 

 as long as third tergite. 



Black; face, clypeus, cheeks, mandibles, orbits opposite antennae, 

 and a small spot near top of each eye behind yellow; antennae en- 

 tirely black; tegulae black; wing venation brown; front and mJddle 

 coxae, basal joint of their trochanters, and annuli at bases of their
