ACARINA FROM THE JUAN FERNANDEZ ISLANDS 615 
teriorly widening to almost twice the width between cox IV, with rounded 
posterior margin. One pair of hairs, inserted a little in front of posterior margin 
of cox IV, marginally. 
Round the posterior margin there are two pairs of pointed hairs. 
Anal shield pearshaped, with three hairs; round the anterior half of the 
shield 3 pairs of pointed hairs. Half-way between the posterior pair and the 
lateral margin there is one pair of leaf-shaped hairs, and on a level with the 
postanal hair there is another pair of similar shape, all the other ventral hairs 
being narrow and pointed. 
Legs with fairly distinct scaly texture, at least on femora and tibiz. 
Legs I (fig. 142) with very short femur with two straight, stout ventral 
bristles on low wart-like projections; genu slightly longer than femur, with one

similar ventral bristle, and subventrally, on the exterior side, one perpendicular 
tactile hair; tibia slightly longer than genu, with one ventral, stout bristle a 
little before the middle and further back one perpendicular tactile hair; tarsus 
straight, twice as long as femur. 
Legs II (fig. 143) stout, with short femur, genu and tibia; femur ventrally 
with two stronger bristles, the posterior one ‘pointing obliquely. backwards, the 
anterior one forwards, genu and tibia with one strong ventral bristle. 
Legs IV (fig. 144); femur in the distal half with two dorsal, leafshaped 
hairs, ventrally with two bristles, genu with one, tibia with two ventral bristles. 
Mouthparts. I have not been able to dissect the epistome, which 
must be exceedingly hyalin and difficult to see. Mandible (fig. 141) with 
narrow chela; lower jaw with three teeth of almost equal size; upper jaw shorter 
than lower one, with three teeth diminishing in size backwards, pilus dentarius 
between terminal and subterminal tooth. 
The shape of the hypostome I have not been able to see distinctly. -
