256 A. C. OUDEMANS, NOTES ON ACARI. 
Ventral side (Fig. 37). Epimera I and II like in 
the deutonympha, slightly longer though. Epimera Ill and IV 
much longer, straight, slightly convergent forward. Shields. 
Externally of the epimera I a narrow streak of coxal plates I, 
so too internally of epimera I. Externally of epimera II a 
wider band of coxal plates II. Laterally, behind the trochan- 
teres II a high-triangular portion of the anterior lateral shields. 
Coxal plates III very large and long, so that they anteriorly 
nearly reach the anterior lateral shields and outward the edge 
of the abdomen. Coxal plates IV long, reaching the coxal 
plates III and, as far as I could observe, coalesced with them ; 
they miss the portion inward of the epimera IV (like in 
the deutonympha). I don’t know whether the coxae III and 
IV are coalesced with the middle and posterior lateral shields, 
or not, but I think they do not. Posteriorly you observe a 
ventrally sufflexed margin of the posterior lateral shields and 
of the posterior dorsal shields). Hairs: between the sternum 
and the epimera II a pair of minute hairs. To the sides of the 
anterior border or lip of the genital aperture a pair of ditto. 
To the sides of the posterior ends of the lateral chitinizations 
of the genital aperture a pair of ditto. Inward of trochanteres 
Ill a pair of ditto. Between the trochanteres IV a pair of 
ditto. On the anal valves a pair of ditto; the valves themselves 
flanked by a pair of thin short hairs. The lateral long hairs 
are very long and reach the posterior end of the abdomen. The 
shorter lateral hair is placed more inward than in the deuto- 
nympha and is as long as the epimera III Noepigynium. 
Mandibles strong, so that they project forward as 
two cones. 
Maxillae normal. 
Legs normal, slender, as long as, or scarcely longer than 
the .greatest width of the body. 
Male. (Fig. 38. 39). Length about 600 x. Colour 
light brown. Shape very elongate, four times longer than
