ACARI 601 



strip of cuticle where the net-like texture of thb shields is 

 missing. This strip runs across the belly in an even curve back- 

 ward, immediately in front of the anal apertiire. 



Metapodal shields large, with sHghtly wavy, médian 

 margin and acutely pointed posteriorh\ 



Stigmata onalevelbetweencoxaellandlll; peritremata 

 running parallel with the posterior side of the mesopleuric 

 ridges, which they follow to the top, where they bend sharply 

 inwards and run along their anterior side half-way inwards 

 (l)(fig. 120). 



Legs (figs. 130-132). 



Coxaelvery large, conical in outline, with a narrow, thin 

 blade runnimg along the médian side ; antero -latéral angle 

 strongly projecting ; at the latéral side there are two high and 

 narrow blades, running in an obliquely trans verse direction. 

 Of thèse, the anterior one is mucli the lârger, with rounded 

 dentate edgo, while the posterior one is more triangular, ^vith 

 smooth edges. Trochanter with thin blade along its médian 

 margin ; the blade at the fémur with fine teeth, separated by 

 shallow, rounded incisions. 



Femora II to IV with comparatively large blades ; those of 

 fémur III divided by the insertion-pore of a hair into two 

 irregularly dentate, triangular blades, the distal part of which 

 is twice as high and broad as the proximal one ; blade of f e m u r 

 IV with smooth edge highest up near the distal end. 



URODISCELLA Berl. 



The systematic position of the présent species, of which there 

 is only a female in the collection, is very difficult to ascertain, 

 and, as a matter of fact, it has no place in the gênera into which 

 Berlese has divided the Uropodinae. As, however, my mate- 

 rial is insufficient to allow of any investigations into the ques- 



(1) Owiug to tlie steepness of the anterior side of the ridge it is impossible to discern the last 

 part of the peritrema ■nithout dissectiug the animal ; Iience, in Berlese's description (and 

 drawing) only the outwardly directed part is mentioued.
