It is slightly pointed in front, and the proximal part of the dorsal 
side is curved downwards, because the basal upper point is directed 
upwards. The joint is provided with comparatively narrow fan hairs 
below and along the sides; there are very few pointed hairs. Above 
there are only few fan hairs. The femur (fig. 1 6) is seven to 
eight times as long as high and is composed of two pieces, a 
proximal short one (6!) and a distal long one (6?). The two pieces 
are separated by a distinct groove. The lower margins of the two 
pieces are curved upwards and merge into each other, only marked 
by a slight groove. The upper margins form an obtuse angle with 
each other, by which the more upward direction of the femur is 
assisted. Between the trochanter and the femur there is a very 
well developed ginglymous articulation. As there is no articulation 
between the two pieces, and as there are no muscles to move them 
towards each other, they must be regarded as one joint; compare 
with this the proximal femoral part in the Prostigmata. The distal 
piece is enlarged towards its point and its upper side is somewhat 
curved downwards. The sides are provided with a row of thin, mostly 
hairy fan hairs, the dorsal side with rows of many pointed and few 
fan hairs. Below there are pointed hairs and fan hairs, the former 
more outwardly. The patella (fig. 1 c) is enlarged towards its point. 
The direction of the joint is not exclusively perpendicular but also 
slightly lateral. The sides are provided with fan hairs, the dorsal 
and ventral side with both fan hairs and pointed hairs. The tibia 
is as long as the femur but more slender, and by a circular median 
incision it is divided in two pieces. The upper side is curved 
downwards. The front side is provided with a row of pointed hairs, 
the hindmost with pointed and fan hairs. The dorsal and ventral 
margins are provided with many pointed and few fan hairs. Å 
dorsal and a ventral hair are usually placed opposite to each other. 
The metatarsus as well as the tarsus are short and little developed 
compared to those of the other legs. They are provided with long, 
slender pointed hairs; the metatarsus bears near its base a dorsal, 
triangular pointed hair. Near the point of the tarsus there is 2
