404 AMEUrCAN HYMENOPTERA. 



rior aspects tliereof ; these spines are each rather blunt and iibout as thick and 

 h)ng as the last two joints of the antenna' and directed backward, a little down- 

 ward and a little backward; winjis somewhat clouded witb brownish but trans- 

 parent; nervures brownish, stiornia yellowish testaceous, with a brownish tint, 

 the second abscissa of the cubitus approximately as long as the first abscissa of 

 the radius which in turn is about two-thirds as long as the radial side of the 

 stigma; legs apparently simple and yellowish testaceous. 



Abdomen. — Smooth and polished, castaneous to blackish, the second dorsal s<g- 

 ment greater in extent than the rest of the exposed portion of dorsum of abdo- 

 men put together, about as wide on each side as at apex, which last is approxi- 

 mately one and one-half times as wide as at base; the first dorsal segment with 

 a median longitudinal parallel sided, elevated, longitudinally striated sjiace 

 which is as wide as the segment at its base and separated flora a smooth polished 

 triangular space on each stde by rather salient edges; ovipositor springing from 

 the apex of the abdomen of equal length or nearly, the portion prolonged beyond 

 the tip of the abdomen, a little shorter than the metatarsus of the posterior legs. 



Types. — University of Kansas. 



Type locality. — Lawrence, Kansas. 



One specimen taken in June ;it twilight by E. S. Tucker. 



Hedysoinus wicliitiis n. sp. 



Suhmedian cell of anterior wings a little longer than the median 

 on the externo-niedial nervure ; front e.xcavated and polished be- 

 tween the insertion of the antennae and the ocelli ; second joint of 

 the antennse about one third as long as the third ; first transverse 

 cubitus represented by a stump of a nervure not as long as tlx; first 

 abscissa of the radius and which if completed would presumably be 

 interstitial with the recurrent nervure, 



%. — 3.5 mm. — Head. — Antennse seemingly as long as the head, thorax and 

 abdomen combined, apparently 23-jointed, the joints soldered together, so as to 

 preclude their positive differentiation, even with the aid of a lens magnifying 

 twenty diameters; head apparently uniformly sculptureless and polished. 



Thorax. — More or less granular, shining; parapsidal grooves distinct on the 

 anterior half of the dorsulum, extending to the posterior margin of this sclerite, 

 but not so distinct on the posterior half on account of the rugulose tegument be- 

 tween in this region, metanotum with a somewhat triangular area occupying 

 nearly all its area, smootlier and more shining than the adjoining parts and longi- 

 tudinally bisected by a rather low, indistinct ridge, which is just about as con- 

 spicuiius as the ridge, which imperfectly encloses the aieas. 



Abdomen. — Mostly granular and shining, partly smooth and polished ; the first 

 dorsal segment longitudinally rugulose, appearing somewhat longitudinally 

 striate; the second dorsal segment not so coarsely sculptured as the first and 

 divided into three parts by lateral longitudinal furrows that are not deeply 

 impressed but still distinct, the lateral parts triangular and equal the central part 

 nearly oblong and a little wider at base than at apex ; the third and fourth dor- 

 sal segments much the same in sculpture as the succeeding ones, but with a faint 

 shining, median, longitudinal laised line on the basal half.
