TRÄGÄRDH, ACARI. 43 



also, and to a still greater extent, the antero-lateral angle, the free blade of which 

 is kidnex-shaped in outline and oovers as well a pari of the anterior blade as the 

 whole basifeaiur. On tlie ventral median side, on a level with the hair, there ia 

 a Short, low tubercle. There are, beside the one mentioned above, two hairs, one 

 perpendicular, in the niiddle and one near the front niargin. 



Feniur clavated, with distinctly deniarcated, short basifemur. The anterior edge 

 projects into a sliarp blade which is divided into three lobes by two sharp incisions, 

 in the bottoni of which two hairs are inserted. The posterior lobe is twice as high 

 as the others and exhibits a narrow ridge which runs across the basis of the femur. 

 Near the basis, opposite to and nearly touching the antero-lateral blade of the troch- 

 anter, there is a sniall flat tubercle. The exterior edge of the femur is strongly curved 

 and provided with 4 short, feather-sbaped and curved bristles; on the dorsal side 

 there are two stout, pointed and perpendicular bristles, and on the ventral side there 

 is one sniall, inconspicuous hair in the centre. 



Genu and tibia very short, of equal size and shape, with one hair each in the 

 middle. ventrally, and two on the outer side. 



Tarsus very long, cylindrical, with the exterior side sligthly excavated, provided 

 with small scattered hairs, except on the exterior side, at the top, where there is a 

 dense bündle of about 15 long hairs, pointing obliquely outwards. The top has a 

 low, cylindrical projection, where a very long straight hair is inserted. 



Legs II — IV do not exhibit anything peculiar, the femora being provided 

 u'ith the usual blade-shaped edges, which are low and triangulär with rounded 

 margin.

The dorsal side (PI. 3, fig. 19) is covered by a large central shield and a 

 narrow marginal shield, which are fused together at the anterior end. The dorsal 

 shield is poHshed and bears numerous small hairs arranged in rows, niore or less parallel 

 with the margin. The marginal shield bears on the dorsal side a row of about 34 

 pairs of hairs with interstices equal to their own length. The ventral side of the 

 marginal shield is of the shape typical for the genus, i. e. divided into small square 

 plates by transverse light-coloured lines; each plate with a hair in the centre, di- 

 rected straight outwards and scarcely extending beyond the margin ; there are about 

 25 plates.
