ANDRENID^E NOMADID^E. 269 



DESCRIPTION. 

 ? 



Very like the species just described, but the head is cloathed 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 underside of the body and of the last abdominal seg- 

 ment above are black, except those on the posterior thighs forming the flocculus, which are whitish, 

 as are those of the anterior part of the abdomen.

N. f Americana J ferruginea, thoracis linea dorsali nigra ; abdomine basi nigra, segmentis tribus primis apice fuscis.

A single specimen taken in Lat. 65°. 



DESCRIPTION. 



Body dark-ferruginous. Thorax with a longitudinal mesal black line, less distinct on the meta- 

 thorax : 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 underside : first segment of the abdo- 

 men 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 ruficornis and striata, but it has only a single black stripe on the thorax. 



' This tribe, to which the modern genera Ammobates, Phileremus, Epeolus, Nomada, Pasites, Mdecta, Crocisa, and O.raa 

 belong, includes those bees that, like the cuckoo, deposit their eggs in the nest of other bees. See Mon. Ap. Angl. i, 150, 

 and N. D. D'H. N. xxiii, Article Nomada.
