J . Anterior margin of clypeus more narrowly rounded in this sex, 

 not dentate; antennje stouter; sculpture somewhat coarser; the disc of 

 the propodeum more distinctly furrowed; pygidium less pilose. Colored 

 like the o . 



One o , Norton county; eleven ^ g , Wallace, Morton and Wichita 

 counties; August 5-24. Thei'e is also a g (this sex I do not find de- 

 scribed) in the collection of the Philadelphia Academy of Sciences. The 

 species is easily recognized by the orange-red band on the abdomen and 

 by the opaque notum.

o . Very like vegeta. Of moderate build. Clypeus rounded out an- 

 teriorly, sparsely coarse punctate, two obscui-e lateral teeth; antennEB 

 not long, of fairly uniform thickness, joints 3 and 4 subequal; inter- 

 ocular space at vertex about equal to antennal joints 2-4; front and 

 vertex very finely punctate; scutum and scutellum appearing granulate, 

 the sides finely granulate-punctate; disc of propodeum rather indis- 

 tinctly and finely transverse-striate; a median sulcus, which is quite 

 deep; posterior face finely granulate-striate, the median sulcus deep; 

 legs well spined, the fossorial comb well developed; abdomen hai'dly 

 punctate above, a few large punctures below; pygidium smooth, with 

 some large separate punctures, its sides somewhat arcuate. Black; 

 tarsi becoming brown apically; vdngs rather dark fuscous; apex of 

 pygidium brownish. Insect covered with veiy short, inconspicuous pile; 

 pygidium with sparse bristles on apical half. Length, 12 mm. 



Two o p , Clark county, Kansas; June; F. H. Snow. One of these 

 specimens is the type. 



Larropsis tachysphecoides (Vier.) 

 Ancistromma tachysphecoides Viereck; Trans. Am. Ent. Soc, XXXII, 



209-10; 1906. ^ . 



"Belongs near chilopsidis, from which it is very different." — Vier. 

 T . Somewhat slender. Anterior margin of clypeus rounded out, 

 no teeth laterally; antennae not slender, of rather uniform thickness, 

 third joint about one-quarter shorter than fourth ; interocular space at 

 vertex only a little less than at clypeus and greater than length of an- 

 tennal joints 2-4; punctui-es well separated on the middle of front and 

 vertex, more closely punctate laterally; scutum and scutellum with 

 rather large separate punctures, the mesopleurje with large shallow 

 ones; disc of propodeum transversely striate at the median furrow 

 po.sterior face granulate, with a wide and deep fovea near the top, the 

 sides rather finely rugose-striate; legs moderately spinose; third sub- 

 marginal cell of fore wings wider than the second along the radius; 

 last dorsal segment of abodmen with shallow punctures, the eighth ven- 

 tral slightly emarginate mesad. Black; tegulae and venation testaceous; 

 legs, except coxae, trochanters, and a part of the middle femora, and 

 the abdomen brownish testaceous. Very slightly pubescent. Length, 

 8 mm. (type).
