Z. xanthographa, Germ., PI. C, fig. 11 {x. maritima examd.), 

 is not the same species, I believe, as alpina; the bifurcate 

 tegumen has the sclerites decidedly broader and bolder; the 

 armature is very similar, but the harpagines decidedly narrow 

 and different in shape. 



Z. transiens, Eocci, PI. C, fig. 12, D, 13 is evidently a 

 form of xanthographa, with its narrow harpagines and longer 

 bifurcation of the tegumen. 



Z. transalpina, Esp., PI. D, fig. 14, is certainly a different 

 species; it has the tegumen shortly bifurcate with broad 

 sclerites; the armature has quite small teeth with peculiar 

 shagreening that is rather extensive; but the armature on 

 the lower margin of the penis sheath is much reduced and 

 finer, and the harpagines shorter and squarer. 



Z. latina, Vrty., PI. D, figs. 15, 16, is evidently a race of 

 transalpina, all the organs being similar. •
