[269.] ^ . — Very like the species just described, but the head is clothed 

 with black hair ; that of the thorax and base of the abdomen is tawny-red ; 

 the brush of the posterior tibia is changeable, as the site varies, from black 

 to white ; the hairs of the under side of the body and of the last

 of the abdomen. 



FAMILY NOMADID^. 



373. NOiMADA Americana Kirby. — Plate vi., fig. 3. — Length of body 

 4^ lines. A single specimen taken in Lat. 65°. 



Body dark-ferruginous. Thorax with a longitudinal mesal black line, 

 less distinct on the metathorax ; breast with a black spot on each side ; 

 wings, as in the rest of the genus, embrowned with a white spot near the 

 tip ; thighs black at the base on the under side ; first segment of the 

 abdomen black at the base, and, with the second and third, brown at the 

 apex. 



This is the only American Nomada I ever saw, and Fabricius describes 

 none from that country. It comes near Nomada ncficoniis and striata, but 

 it has only a single black stripe on the thorax. 



[Dr. Packard states that these Cuckoo-bees, the Nomada, are very 

 numerous in America.]
