This quite distinct species runs out in the tables to P. cly- 

 peatus Cresson = P. cressoniellus Ckll., but is easily distin- 

 guished by the color of the legs, and other characters. 



2. Panurginus innuptus Cockerell. 



Present over the entire state, but much more abundant west- 

 wardly. Warbonnet Canon, Jim Creek, Crawford, Bridgeport, 

 Haigler, Springview, Cams, Niobrara, Long Pine, Neligh, 

 Broken Bow, West Point, and Lincoln. Flies from June 16 to 

 to August 28, visiting the flowers of Branneria angustifolia, 

 Ratibida columnaris, Hclianthus annuus and H. petiolaris, 

 Grindelia sqitarrosa, Pctalostemon violaceus, Medicago sativa 

 and various species of Solidago. We have numerous pairs 

 taken in copula. The male often lacks the black dots on the 

 clypeus and on the lateral face marks. • 



3. Panurginus renimaculatus Cockerell. 



Lincoln and West Point, flying at the same time and upon the 

 same flower as P. ornatipes, including also species of Aster. In 

 a series of thirty-three specimens of this species from Lincoln, 

 there are two males. The male, hitherto unknown, is distin- 

 guishable by its small size (5.5 mm.), black tubercles, black 

 nervures and stigma, and strongly narrowed, deeply emarginate 

 median process of labrum. 



4 Panurginus stigmalis n. sp. 



6"- — Length 8 mm. ; clypeus, labrum, mandibles and lateral face marks 

 extending nearly to bases of antennae and ending obtusely, bright yel- 

 low, the remainder of the head black. Median process of labrum with 

 its sides forming distinct ridges, converging toward the slightly ejnar- 

 ginate tip. Clypeus uniformily closely punctured. Antennae black, 

 with joints 3- n bright brownish testaceous beneath. Mesonotum 

 coarsely, closely punctured, pleura very coarsely punctured, meta- 

 thorax finely and indistinctly punctured, its base with a row of short 

 irregular striae. Tubercles yellow. Tegulae testaceous. Wings hyaline 

 basally but becoming darkened toward their apices, the nervures 

 brownish fuscous, stigma very large and dark. Legs black, with all 

 the tarsi and knees, anterior tibiae except a spot behind, and both ends 

 of intermediate and posterior tibiae, yellow. Abdomen deep shining 

 black, basal segment subimpunctate, the following ones sparsely but 

 distinctly punctured basally and especially laterally, apical margins of
