This is all of his description that is of any value; tUv first will fit 

 both species, while the last will only suit P. xerratun, for the serratures 

 are ]>resent in /*. branmri, althoujjh they are small.

 P. pi'UHsiflranicus is identical with xerrntHH^ or, at any rate, a species 

 distinct from my hranneri. 



I have examined a number of specimens collected by Mr. Charles B. 

 Brainier, but most of them are l)roken. x\ll the females in the collec- 

 tion are mucli smaller than the male, as the following measurements 

 will show :
