the elytra testaceous, but sli;^litly puler in the niidfUe, with 

 the suture bhick and a tendency to a darkening round the 

 sciitelluin. There is also a variety (male) in which the 

 elytra arc entirely black, and no doubt all intermediates 

 occur. The notable disparity in breadth between the sexes 

 given by Dr. Ohaus is not confirmed by our larger series, 

 nor is there a sexual difference in the thickness of the hairy 

 clothing. The latter is scarcely closer at the sides of the 

 segments, as stated by Dr. Ohaus.

A small species, rather lirger than the South- African 

 P. Corydon, Oliv., and quite black above. The cephalic 

 horn of the male is rather slender and a little compressed 

 laterally, and is represented only by a very slight prominence 

 in the female. Tlie thoracic excavation in the male is very 

 small in our only example of that sex and its posterior margin 

 is not sharply defined.
