and between the lateral areas, which latter are more moderately reticulate and 

 twice as broad on the apical half of the inetanotum as on the basal half thereof, 

 the areas between the central area and the lateral areas are rather triangular and 

 granular; nietapleura reticulate; nietathorax dorsally convex ; legs pale yel- 

 lowish-testaceous, tarsi inclining to brownish; wings transparent, tinted with 

 brownish, most of the nervures and the stigma brown ; first and second trans- 

 verse cubiti mostly weak and colorless, costal nervure between the stigma and 

 base of wing yellowish-brown. 



Abdomen. — Mostly black, the first two dorsal segments partly castaneous; first 

 dorsal segment wider at apex llian at base, which last is about two-thirds half 

 the length of the segment, which is dullish and longitudinally striate, except for 

 a median area, which holds pretty much the same relation to the segment as the 

 median area of the mesonotuin bears to that sclerite, but on its basal half it is 

 mostly bounded on each side by a raised line and rather transversely foveate, 

 while on its apical half it is mostly longitudinally striate like the adjoining sur- 

 face; the second dorsal segment mostly dullish and more finely longitudinally 

 striate than the first segment, but medially the strife are ill defined and wider 

 apart, with polished surface between them ; the third dorsal segment is longitu- 

 dinally striate only at base, mostly smooth and shining like the rest of the dorsal 

 segments; ovipositor and sheaths dark brown, tipped with blackish and approxi- 

 mately 3.5 mm. long. 



Type. — University of Kansas. 



Type locality. — Near Lauder, Wyoming.

%. — 7.5 mm. Head. — Black and polished, except for the face below the an- 

 tennge which has widely separated punctures and is longitudinally divided by 

 an impunctate space which is not as wide as the flagel and which is prolonged 

 above as an impressed line, and the cheeks which have a few scattered puncture?, 

 frons transversely impressed with a deeper longitudinal median impression ; 

 antennae black, the scape nearly three times the length of the pedicel but nearly 

 as long as the first joint of the flagel tlie latter more than 17-jointed, its joints 

 subequal. 



Ihorax. — Mostly shining black; pronotum indistinctly sculptured, with a me- 

 dian transverse constriction, the posterior portion being humped; propleura 

 partly polished, punctate, partly rugulose; prosternum polished, sparsely but 

 distinctly punctured, parted anteriorly and posteriorly by a deep impression, the 

 anterior of which is deepest and divided longitudinally by an elevated fold 

 formed apparently by the union of the two sides of the segment, immediately 

 adjoining this fold on each side is a narrow rugose space ; mesonotum snbtrilo- 

 bate, the median lobe a little larger than the lateral ones and more strongly con- 

 vex, slightly longitudinally impressed along the middle of the anteiior half and 

 polished with scattered few punctures, the posterior half rugulose, the lateral 

 lobes more uniformly polished and with a few scattered punctures; scutel sepa- 

 rated from the mesonotum by an almost smooth, shining transverse band, the 

 scutel proper somewhat arched, indistinctly punctured and sculptured, rather
