Resembles Ph. alhitarsis closely in form, in tbe small 
thorax and subulate elytra ; but differs in the less 
abruptly clavate hind femora. It mimics a pale species 
of bee of the genus Melipona, even to the black hairy 
tufts of the hind tibise.

Niger, sericeo-tomentosus; thorace oblongo-ovato, dorso

abdomine rufescente, sparsim griseo-piloso ; pedibus an-

et tibiis lineis testaceis; pedibus posticis fulvo-rufis.

Closely allied to the common Brazilian A. aurulentus; 
differs in its slenderer form, black head, thorax, breast, 
and four anterior legs, and in the red untomentos© 
abdomen. It agrees well with Olivieffs description of 
N. ahdominalis, but differs 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 
be the one described by him.
