A. C. OUDEMANS, NOTES ON ACARI. 257 
wide. Texture: smooth in the shields and legs; finely 
wrinkled in the weak parts. ; 
Dorsal side (Fig. 38). Anterior dorsal shield 
wholly occupying the dorsum of the prosoma, except two 
small triangular weak parts behind it, because its posterior 
edge being rounded. Posterior dorsal shield wholy 
occupying the dorsum of the metasoma. Of the lateral 
shields only a narrow part of the middle ones is visible. 
Hairs: the vertical hairs are long, extending before the 
mandibles. The long hairs on the anterior shield are very 
long, at least as long as the metasoma. The accompanying 
hairs, which are minute in the larva, nymphae and female, 
are very long here, extending before the mandibles. The lateral 
hairs which are short in the larva, nymphae and female, are 
very long here, much longer than the width of the body. The 
short thin hairs standing about the ceritre of the metasoma of 
deutonympha and female has become very long here and got 
a more lateral position; they are much longer than the width 
of the body. The rather short pair of hairs behind the ope- 
nings of the excretory gland in nymphae and female has 
become very long here: they are longer than the width of 
the body. Between this pair there is a pair of minute hairs. 
Except one pair of short hairs, all the hairs on the posterior 
edge of the abdomen are rather long; the longest are even 
longer than the metasoma: I could not descern any o pe- 
nings of the nephridia.. 
Ventral side. (Fig. 39). Epimera I long, joined to 
a sternum. Epimera II shorter, very crooked, Epimera II 
and IV shorter than in the female, as long as epimera II, 
but straight and slightly convergent forward. Shields: Coxal 
plates I with deep middle incision. Coxal plates II only a 
crooked triangle outward of epimera II. Coxal plates III enor- 
mous, on both sides of the epimera III, the widest part outside 
of them. Coxal plates IV smaller; contrary to those of the
