Very broadly oval, opaque black, under surface and legs dark testaceous, antenme en- 

 tirely pah;. P. rufa, Mels., is but an immature specimen, as is probably the pollens of 

 Lap. and Bridle. 



Length .16— .22 inch. 



A species of wide distribution.

Similar to the preceding species, hut more elongate, and with the antennae black ex- 

 cept the three basal joints, which are testaceous. The thorax is very feebly and sparsely 

 punctured at middle, while at the sides the punctures are not only denser but coarser, dif- 

 fering in this respect from the preceding species, in which the thorax is scarcely more 

 punctured toward the margin than at the middle. The under side of the body and legs 

 are pale brownish. 



Length .16— .20 inch. 



Middle and Southern States.

At the suggestion of the manuscript of the late Dr. Zimmerman, T refer to this species 

 our largest opaque black species, heretofore considerd flavipes. The description of the 

 latter corresponds exactly with that described by Haldeman some years after as basale. 

 Janus differs from flavipes in having the terminal joint of the antenna; ferruginous, and 

 by the thorax being regularly, sparsely and finely punctured. The under surface and legs 

 are pale ferruginous. 



Length .24-30 inch. 



From the Southern States, California, Arizona, and New Mexico. The types were 

 from Peru.
