the hair on the under side of the metatarsus rufous; the 

 apex of the tarsi rufous. The femora and tibiae are normal, 

 not dilated, except that the hinder tibiae on the inner side 

 are triangularly produced, but not sharply, the apex being 

 rounded. x\bdomen shining, impunctate; the base of the 

 segments belted with white, depressed pile ; the second to 

 fourth segment with wide transverse furrows near the 

 base ; the ventral segments smooth, shining ; their apices 

 fringed with short, white hair ; the sides of the third and 

 fourth with long, white hair ; the penultimate segment 

 broadl}' depressed in the middle, with a smaller, somewhat 

 pear-shaped, depression on either side at the apex. 



This is perhaps not a true Noinia. The trophi do not 

 differ in form from those of that genus. The only point 

 in which the legs agree with those of Nomia is in the 

 projecting apex of the hinder tibiae. It differs in the 

 interstitial first recurrent nervure and in the shorter wings.

In Bingham's Key {I.e., p. 471) it comes in " A. Abdo- 

 men black, with entirely black pubescence above," 

 and " C. wings h}'aline," which only contains the ^ of 

 M. antJiracina, a very different species from M. nigricans, 

 being much larger, the pubescence on the face bright 

 fulvous, the fore legs more or less rufo-testaceous, the 

 wings infuscated at the apex, the fore legs spined, &c. 



Entirely black, the wings hyaline, the costa and 

 nervures fuscous, darker at the base. Head below the 

 ocelli thickly covered with long, pale, behind the ocelli 

 more sparsely with longish, black, hair ; front and vertex 

 strongly punctured, except a smooth, shining space on 

 the outer side of the hinder ocelli ; the clypeus strongly
