2. Zodion obliquefasciatum, Macquart.— Six specimens from Dundy 

 Co. and Lincoln, Nebraska. 



3. Zodion parvum, Adams. — Seven males and four females from 

 Glen, Sioux County, Nebraska, August, 1906, on Helianthus and Solidago 

 (P. R. Jones). As this species has hitherto been known from but a single 

 male from Arizona, I give a description of the female : 



9. — Length, 3.5 mm. Black species. Face and cheeks yellow, the 

 latter with a silvery reflection, front fulvous, with a narrow black line on 

 each side, vertex black. Antennae red, first joint and upper part of third 

 blackish, arista black. Proboscis black, 2.4 mm. in length, labella in 

 length equal to the height of the eye. Palpi short. Mesonotum and 

 scutellum black, subfulgent, pollen gray, more evident on the sides. Legs 

 black, excepc the base of tibiae, metatarsi and pulvilli, which are yellow. 

 CoxcC and outer part of tibiae with a silvery sheen. Wings nearly hyaline, 

 very slightly tinged with brown ; first posterior cell closed and petiolate, 

 petiole nearly as long as the posterior cross-vein. Pile everywhere black. 



4. Zodion scapu/are, Adams. — Ten males and ten females, and two 

 pairs taken in copula ; Lincoln, Nebraska, July and September, and Glen, 

 Sioux County, Nebraska, August (P. R. Jones). Formerly known from a 

 single male from Arizona. The female agrees with the description of the 

 male, except that the abdomen is entirely black, subfulgent with gray 

 pollen, which is more prominent on the sides. The whole series varies 

 from 5 to 6.5 mm. in length. The proboscis is about 4 mm. in length, 

 with the labella nearly as long as the height of the eye. The petiole of 

 the first posterior cell is only slightly longer than the small cross-vein. 



5. Zodion pygtnaeum, Williston. — Numerous specimens from Lincoln, 

 West Point and Glen, Sioux County, Nebraska, on Solidago (P. R. Jones). 

 Rather common in the State from June to August. Formerly recorded 

 from California, Colorado and Mexico. 



4. Stylogaster, Macquart. 

 I. Stylogaster neglecta, Williston. — One female from West Point, 

 Nebraska, June 22, 1905 (H. S. Smith), which agrees in every way with 

 the description. 



5. Dalmannia, Robineau-Desvoidy. 

 I. Dalmannia ?iigriceps, Loew. — Two males from Lincoln, Nebraska, 

 and two females from Sioux County, Nebraska, which agree with the 

 description, except that the posterior femora of the males are black, with 



the base and apex yellow, and the anterior femora in the females are black, 

 except at the apex, which is yellow.
