external tooth, inserted before middle of eye. Marginal cell at 

 apex rounded, widely separated from costa, nearly as long as 

 the combined three submarginals but distinctly shorter than 

 the first discoidal cell. Submarginals three, subequal in length 

 along the cubitus, first one trapezoidal, second slightly nar- 

 rowed above, third narrowed about one-third. First transverse 

 cubital nervure straight, second slightly curved, third bulg- 

 ing strongly out toward apex of wing. First and second 

 recurrent nervures joining second and third submarginal cells 

 respectively near their apices. Median cell much larger and 

 nearly twice as long as the submedian. Discoidal nervure 

 much longer than the sub-discoidal nervure. Stigma medium- 

 sized, well developed. Scutellum bilobed. Legs stout, simple. 

 Claws with a short inconspicuous internal tooth. Tibial spurs 

 short and stout, only one on middle tibiae, dark testaceous 

 and microscopically pectinate. Abdomen short, conical, seg- 

 ment 6 of $ exerted, elongate acuminate, with a distinct 

 pygidial area. 



Viereckella obscnra n. sp.* 



9. — Length 10 mm. ; shining black, nearly bare. Head coarsely punc- 

 tured, very shallowly on clypeus and cheeks, deeply so on front, the 

 sides of vertex finely punctured. Supraclypeal area elevated, con- 

 tinuous with a median carina between bases of antennae. Antennae 

 black, scape finely punctured, the flagellum testaceous beneath, joint 

 three decidedly shorter than four. Labrum shining, punctured like the 

 front. Mesonotum shining, coarsely and closely punctured, no well- 

 defined discal space, scutellum and pleura similarly but more coarsely 

 punctured, postscutellum opaque, irregularly reticulate. Metathorax 

 with a smooth, shining, almost impunctate basal triangle, elsewhere 

 punctured like mesonotum. Tegulae large, shining black, finely punc- 

 tured. Wings heavily darkened, nervures and stigma black. Basal 

 abdominal segment subimpunctate, except laterally, following segments 

 feebly and mostly indistinctly punctured, the margins of the segments 

 not depressed. Pubescence short, sparse, pale grayish white, except 

 that on tibiae and tarsi, which is largely black, and that on the inner 

 surface of the tarsi which is orange, longest on pleura, scutellum and 

 postscutellam. The abdomen has very loose thin lateral fasciae on apices 

 of segments 1-5, and segments 4-6, bear some black bristles ventrally.
