260 A. C. OUDEMANS, NOTES ON ACARI. 
soft skin (?), between the two shields and quite on the edge 
of the body a pair of »shoulder«-hairs, quite stiff, as long as 
the half of the width of the body. Between legs III and IV, 
near the edge of the body, a pair of hairs, reaching the end 
of the abdomen. On a line with the joint between genu and 
tibia IV a lateral hair, extending a little beyond the abdomen. 
Finally on the posterior margin, a pair of inner short thick 
needle-shaped pins, and a pair of outer long hairs (as long 
as the body); and on the edge itself 2 pairs of shorter hairs. 
Ventral side (Fig. 41). Very complicate. Epimera 
I halfway united to a sternum. Epimera II as long as epi- 
mera J. Epimera III and IV of equal length, twice longer 
than the respective trochanteres, with exactly longitudinal, distal 
two third part, and suddenly inward nodded proximal third 
part. Shields. Coxal plate I represented by a narrow band 
outside of epimera I and a large distal piece inside of epimera 
II. Coxal plate II only represented by an almost square piece 
outside of the distal half of epimera II. Coxal plate III and 
IV wholly developed but fused with a large side-shield outside 
of the epimera. Anterior lateral shield rather wide triangular 
or more or less square. Middle lateral shield enormously devel- 
oped and fused with coxal plate III. Posterior lateral shield 
less developed, though large, fused with coxal plate IV. 
Abdominal part of posterior dorsal shields a little sufflexed 
ventrally. Curious and noticeable is the presence of a median 
poststernal round little shield and that of a tyroglyphidian 
round real sucker-plate! — Epiandrium elongate horse- 
shoe-shaped. Penis very small, rodlike. Genital suckers before 
the epiandrium. Anus terminal, flanked by the small but 
well developed anal suckers and by a pair of small hairs 
before the suckers, all these organs on a round plate or shield. 
Hairs. Inside of epimera II a pair of short hairs; inside of 
coxal plate III one pair of ditto; inside of the proximal part 
of epimera IV a pair of ditto; before the genital suckers a
