WILLIAMS: LARRID^ OF KANSAS. 179 



MiscopHUS Jurine. 



Juiine; Nouv. Meth. Class. Hym., p. 205. 



Head wider than thorax; mandibles strongly excised beneath, not 

 dentate within; antennae quite slender. Marginal cell lanceolate, not ap- 

 pendiculate; two submarginal cells, each receiving a recurrent nervure; 

 armature of legs variable. No pygidial area. 



^ Has a feebler tarsal comb and stouter antennae than the o . 



The genus is poorly represented in the United States. 



Miscophus americanus Fox.

This is a small black insect, 3 to 4.5 mm. long, having the clypeus 

 three-lobed, the wings infuscated apically, and the abdomen shining. 

 The type was taken in Camden county, New Jersey. The three 7 t and 

 one 2 in the Snow collection come from Rush and Barton counties; 

 June, 1912. 



BOTHYNOSTETHUS Kohl.

 Fox; Proc. Acad. Nat. Sci. Phil., 550; 1893. 



Body stout. Head as wide or wider than thorax; eyes diverging to- 

 wards vertex; antennas rather stout; ocelli large, arranged in a low 

 triangle; mandibles not emarginate beneath. Pronotum almost on the 

 same level as the scutum, which is large; propodeum rather short; stigma 

 of primaries quite large, marginal cell lanceolate at apex, no appen- 

 diculation, first submarginal cell very large, the second petiolate, receiving 

 one or both recurrent nervures: submedian and median cells of the same 

 length on the externo-median nervure; legs stout, feebly armed, hind 

 femora broadest apically. A broad and well-defined pilose pygidial area 

 in both sexes. 



As far as I am aware, this genus is represented in the United States 

 by a single species. It is an anomalous larrid, and seemingly far removed 

 from any other genus of the family. The large stigma of the fore wings 

 resembles that of some of the Pemphredinidae. The apically thickened 

 hind femora easily separates it from the other genera.

Two ^ ^ oi this shining black wasp were taken in Logan county, 

 end of June, 1910. They are 5.50 mm. long. The insect seems quite 

 variable, both the venation and the margin of the clypeus differing in 

 the two Kansas specimens. The venation as illustrated in figure 17 does
