P. caudatuSy Nob. notwithstanding their great apparent 

 difference. But this cannot be determined without more 

 specimens, and a better acquaintance with them both. 



Since the above was written, I have obtained many 

 specimens of this species, all corresponding in apparent 

 sexual character, excepting that in some, tbe second 

 joint of the antennae is so far immersed in the first, as to 

 be hardly visible ; still as It is not, in any, much exserted, 

 this character is probably dependent on the greater or 

 less degree of contraction in drying.
