 p. 385 (1897). 

 This genus of rather highly coloured locusts inhabits Northern Mexico and the 

 extreme south-western portions of the United States. Up to the present time three 

 species have been described. They were tabulated in Scudder's ' Revision of the 

 Melanopli,' p. 386.

This is a characteristically marked insect and cannot be confounded with any other 

 species known to the present writer. It does not appear to be common at any locality 

 within its range. Very likely P. pantherinus is confined to some special food-plant.

As stated in connection with P. pantherinus, this and the preceding species must 

 also be confined to special food-plants. It should also occur further south in Mexican 

 territory.

 This genus resembles Melanoplus and its near allies. The different species range 

 from Northern Mexico northward to Idaho on the Lower Snake River.
