A. C. OUDEMANS, NOTES ON ACARI. 33 



forward ; distal hair rod-like, distally suddenly nodded and 

 hairy. Femur with bristle-like hMir outward, and three-lobed 

 knife-like hair outward and more distally. Genu with two 

 knife-like luiirs inward of which the sharp edge is forward. 

 Tibia and tarsus normal. 



Legs (fig. 10) slender, resp. 1415, 990, 990 and 1472 ix 

 long. Coxa I (fig. 11) with serrate edge inward. Femur II, 

 genu II, femur III, genu III, femur IV, and remaining joints 

 of leg IV with rod-like, distally hairy hair (fig. 12). Tarsus IV 

 quite distally with short supra-praetarsal hairs (fig. 17). Prae- 

 tarsus IV long, slender, distally with a pair of claws, a 

 semicircular supra-unguinal sticking piece which shows 8 folds, 

 and a sub-unguinal wide almost semicircular caruncle. There 

 is no trace of spines at the distal end of 

 the tarsus itself (compare fig. 17 with fig. 9, 29 and 37). 



Male. L engt h 1230 — 1275 u. Colour darker than the 

 deutonyrapha, brownish. Shape elliptical, slightly shouldered 

 behind legs II ; much better above coxae I. Text ure scaly on 

 the whole body except the unprotected throat (fig. 19) ; more- 

 over the body is leathery, though harder than the female. 

 Dorsal side (fig. 18). The anterior and posterior dorsal 

 and the two peritrematal shields fused, though very fine lines 

 of demarcations are discernible. No unprotected parts. Hairs 

 like in the deutonympha, viz. on the anterior shield about 

 16 pairs of small bristles, and four pairs of rod-like distally 

 hairy hairs (fig. 20) on the usual places ; posterior shield with 

 the same hairs as in the deutonyrapha, moreover with those 

 which in the deutonympha are placed in the unprotected skin, 

 so that you may count on the back about 26 pairs, and quite 

 marginally about 9 pairs of small bristles, and one pair of rod- 

 like distally hairy hairs (fig. 20). The foremost median pair and 

 one of the posterior median pairs of the posterior shield are a 

 little larger than the others and correspond with the same hairs, 

 in the protonympha (fig. 1) and in the deutonympha (fig. 10).
