ACARI 529 



with regard to its gênerai shape as well as the form of the 

 metasternal shields, and the position of their hairs, it 

 resembles more the var. monticola and the spécimen from Padiia 

 (compare 1906, pi. 16, figs. 2 and 12). 



Legs. Legs I shaped as in the maie. Legs II (fig. 16) resembling 

 those of the main form, excepting that the projection, at the 

 top of which the fémoral bristle is inserted, is lower. On the 

 other hand, even on the tibia which widens ventrally in the 

 middle, there is a strong, curved bristle which is even longer 

 than that of the genu. Tarsus, contrary to that of the maie, at 

 tlie top with two stout, conical bristles (fig. 17).
