Similar to the preceding species, hut mure elongate, and with the antenna' 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 tin-; 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.

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

 our largest opaque black species, heretofore considerd j!<ir!]><*. The description of the 

 latter correspond-, exactly with that described by Haldeman some years after as hasale. 

 Janus differs from flavipes in having the terminal joint of the antennae 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.
