This is all of his descriptiou that is of any value ; the first will fit 

 both species, while the last will ouly suit P. serrafus, for the serratures 

 are present iu P. hrannerl, although they are small. 



I have never seen a specimen of P. scrratus with the serratures oblit- 

 erated, but, concerning this, Dr. Wood says : * " The serratures in the 

 lateral margins of the side plates are very minute and frequently obso- 

 lete; "and Professor Saussure:t "J/s le sont en ejf'ef, mais si finement 

 qu'on ne distingne Ics denfelures qiCau moyendu microscope ou d''unc forte 

 loupcy Judging from these quotations, I am inclined to believe that 

 P. pennsylvanicus is identical with serratus, or, at any rate, a sj)ecies 

 distinct from my hranncri. 



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

 Branner, but most of them are broken. All the females in the collec- 

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

 will show :
