PAUL R. JONES. 285 



One female from Sioux Co., Nebraska, and a female from Fort 



Assinniboine, Montana. 



I shall not name these specimens because of a lack of sufficient 



material. 



31. TOL.inERUS Loew. 



Tolineriis callidu!« Williston. 



Two females and a male from West Point, Nebraska, which I 



believe belong here. They resemble the following species, but the 



pollen of the face and thorax is more yellowish, the femora black, 



with a red ring at the apex, tibiae red, with a black spot on the 



inner side. The third joint of the antennae more slender, style not 



as long as the third joint. 



Tolineriis notatus Wiedemann. 



Numerous specimens from West Point and Glen, Sioux Co., 

 Nebraska. 



Toliiierns n. sp. 



Three females from Glen, Sioux Co., Nebraska, August 17, 1906 

 (P. R. Jones), which are related to the preceding species, but seem 

 to be different. The third joint of the antennae is more pointed or 

 lance-shaped, occipito orbital bristles white, femora except a black 

 spot on the outer side (more extensively on the hind femora), tibiae 

 except the apex and metatarsi red, tarsi dark brown or black. The 

 posterior margin of the scutellum has two bristles. The pollen is 

 everywhere grayish -white, except on the dorsum of the thorax and 

 abdomen, where it is brownish, being slightly yellowish also on the 

 thorax. In all the other characters this species resembles the pre- 

 ceding one. I shall not name it because of a lack of sufficient 

 material. 



Tolnierus ? n. sp. 



A female from Weeping Water, Nebraska, July 10, 1905 (H. S. 

 Smith). 



The specimen seems to resemble the preceding species in a general 

 way, but differs by having the front and face wider, the gibbosity 

 more abrupt, and a great deal more prominent. The pollen of the 

 front and face is yellowish, mystax black, with a few white hairs 

 interspersed throughout the middle. Occipito orbital, ocellar bris- 

 tles and a row of bristles on the inner eye margin black, beard dense, 

 whitish. Palpi black, with black hairs. Antennae slightly shorter 

 than in T. notatus, black, second joint less than one-half as long as 

 the first, third lance-shaped, slightly shorter than the first joint,
