Resembles Ph. albitarsis closely in form, in the small 

 thorax and subulate elytra; but differs in the less 

 abruptly clavate hind femora. It mimics a pale species 

 of bee of the genus Mch'pona, even to the black hairy 

 tufts of the hind tibias.

Closely allied to the common Brazilian A. aundentus; 

 diHcrs in its slenderer form, black head, thorax, breast, 

 and four anterior legs, and in the red untomentose 

 abdomen. It agrees well with Olivier's description of 

 N. alnhnnlnalis, but dilfers from his figure in the much 

 longer and subulate elytra. If we might assume that 

 the figure is incorrect in this respect, the species would 

 bo the one described by him.
