forwards. Hind margin of epimera IV thickened, behind them a 
transverse fold. 
7. Phyllhermannia dentata n. sp. — Figs. 45—52. 
Length 685 wu. Width 430 u. Length of propodosoma 200 wy, width of 
the same 250 w. 
Colour dark chestnut brown. 
Texture exceedingly finely punctured on dorsal shield, sides of shield 
and proterosoma distinctly punctured; dorsal side of legs reticulated, ventral 
side punctured. 
Propodosoma (fig. 46) broader than long, sloping steeply downwards. 
Rostrum blunt, set off by a fine but distinct transverse suture. The posterior 
margin is not coalesced with the hysterosoma but se- 
parated from it by a narrow transverse strip of weak 
chitin. At the posterolateral angles there is sharp, tri- 
angular tooth which meets a similar tooth situated op- 
posite to it at the anterior margin of the hysterosoma. 
The pseudostigmata (fig. 46) are situated on two 
low, rounded, cushion-shaped projections which leave a 
narrow median furrow between them; on the median and 
posterior slopes of this projections the punctures are 
larger than on the rest of the propodosoma. The pseudo- 
stigmata are straight, trumpet-shaped and point obliquely 
outwards and backwards. The pseudostigmatic or- 
gans are straight and point obliquely upwards and 
backwards, slightly clavate and covered by minute hairs. 
Interlamellar hairs inserted on a level with the

dentata n. sp. Dorsal view, PSeudostigmata, a little further apart than the distance 
legs not delineated. to the pseudostigmata, leaf-like, curved and quite hyalin 
and hence difficult to see. The lamellar hairs are in- 
serted far forwards where the rostral suture meets the lateral margin and are 
of the same shape as the interlamellar hairs. Rostral hairs small and straight. 
Hysterosoma (fig. 45) perfectly oval in outline, about '/e longer than 
its width, evenly arched. It has 3 pairs of leaf-shaped marginal hairs round 
the posterior margin, and two longitudinal rows of resp. 8 and 5 pairs of leaf- 
shaped hairs (fig. 49). These are quite hyalin and difficult to see unless the 
mite is dry, when they are whitish and very conspicuous. 
Mouthparts (figs. 47 and 48). The palps have 5 joints; basal joint 
very short and ringshaped, 2nd joint longer than 3--5 and twice as wide, with 
one small hair inserted subventrally and exteriorly near the middle; 3rd and 
4th joints very short. I have only been able to see tactile hairs on joint 4 
where there are two dorsal, straight hairs, almost as long as joint 5; 5th joint 
tapering in the distal '/s and rounded; it has ventrally and subterminally two 
hairs, curved slightly forwards, at the end three long and straight hairs, dor- 
sally in the proximal half two long hairs curved slightly forwards at the top, 
and on the inner side near the top one hair, pointing obliquely forwards.
