Larropsis minor n. sp. 



^ . Somewhat slender. Anterior margin of clypeus rounded out, not 

 dentate laterally, strongly and closely punctate; antennae rather stout, 

 almost as long as head and thorax; joint 3 somewhat shorter than 4, the 

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

 very closely punctate, the punctures not very fine, however; scutum and 

 scutellum rather coarsely and very closely punctate, giving these regions 

 a granulate aspect; pleurae about as dorsum; disc of propodeum granu- 

 late, with an apical sulcus; indications of transverse strise and basal 

 strise, which diverge to about the middle length, sides and posterior face 

 granulate, the latter with a large fovea near the top; legs weakly spinose; 

 venation normal; abdomen finely punctate; pygidial area with large, 

 separate punctures; eighth ventral segment rounded. Black; fore femora 

 at base, tibiae slightly, and tarsi in part, ferruginous; venation dark brown. 

 Face in part, pleurae and sternum in part, and the abdomen with pale 

 pile; the abdomen rather indistinctly pale sericeous- fasciate. Length, 

 6 mm. (type) . 



One ^ , Seward county, Kansas, August 18, 1911. 



Related to bnineri and pseverugosa, from which it differs in being much 

 smaller, in having generally coarser and closer punctures, etc.

o . Stout. Anterior margin of clypeus broadly rounded out, biden- 

 tate laterally; antennae long and slender, joint 3 a little longer than 4; 

 front rather coarsely but closely punctate; scutum compactly punctate; 

 disc of propodeum sulcate mesad and there rather coarsely transverse- 

 striate, posterior face granulate-striate and with a median impressed line ; 

 legs tolerably spinose; pygidial area of the usual form, well punctate. 

 Black; tarsi in part brownish red, wings dark fuscous, \enation brown to 

 dark brown; first segment of abdomen largely black, the rest orange red 

 or the abdomen all red. Pubescence of pygidium light yellowish brown. 

 Length, 14-16 mm. 



^ . Anterior margin of clypeus not dentate laterally; antennje 

 shorter than in o , distinctly shorter than head and thorax; sculpture 

 generally coarser; metathorax transversely rugose. First three abdomi- 

 nal segments red. Sparse silvery pile. Length, 12-13 mm. 



Eleven g o ; from Wallace, Stanton, Seward, Stevens and Morton 

 counties; July 30 to August 18, 1910-'ll. 



Larropsis ater n. sp. 

 (Fig. 100, ventral plate of j- .) 

 J . Medium stout. Anterior margin of clypeus rounded out, not 

 dentate laterally, strongly punctate, much more sparsely and coarsely 

 so distally; antennae rather stout, nearly as long as head and thorax 

 together, joint 3 somewhat shorter than 4, the interocular space at 

 vertex about equal to joints 2-4; front and vertex finely punctate, in
