VV^Iien compared with A', erythropyffux this new geograjdiical species 

 jilainly (litters from it by the chara<'ters given. The lateral margin of 

 carina* are also slightly crenulate and the anterior is somewhat serrate.

The exceedingly long branch of the copulation foot at once separates 

 intxfralix from the true ery^hropyijns. The inner tooth is also absent, 

 but this is subject to slight variations in crytltropynns.

 These specimens are all females, and I refer tkem to this sjiecies with 



some doubt, but as they are from the region in which P. hranmri is 

 found they must belong to that species and not to P. scrmttfs, which is 

 ii(>t quite so southern in its range.
