This species is apparently very uncommon in Nebraska, since 

 it is known from the state only from a single male specimen col- 

 lected at Bellevue in April, along with a female and eight males 

 of A^. lepida and a pair of A^. carolmae. Before the writer are 

 two females of bella from Ute creek, Costilla county, Colorado, 

 collected June 27 and 28, 1907, by L. Bruner and H. S. Smith, 

 respectively, both of which agree in having the abdomen im- 

 maculate except for large round pale yellow spots on the sides of 

 tergite 2. A third female from Detroit, Minnesota, collected 

 June 17, 191 1, on " Zizia and Sanicula" (C. M. Waldron, 

 Stevens No. 2373), is exceedingly dark red, almost blackish, and 

 has small yellow spots on the sides of tergite 3 as well as on 2, 

 but as it seems structurally similar to the Colorado females it is 

 referred to N. bella, at least for the present.

In 1905 (/. c.) Cockerell pointed out the close relationship 

 between A^. lepida Cress, and A'', cuneata Robertson, and because 

 of the presence of both forms, together with apparently inter- 

 grading specimens, in the same locality in Colorado he stated
