without any hairs dorsaily. Third abdominal segment with a 

 pair of dorsal hairs. Fourth abdominal segment with two pairs 

 of hairs, the inner ones being much shorter than the outer, 

 exactly as in P. eccoptogasteris. The paired lateral epimeral 

 structures lying between the first two legs are not joined to the 

 central linear (longitudinal) chitinous structure (Vitzthum's 

 figure of the ventral surface of P. eccoptogasteris shows these 

 lateral epimera joined to the longitudinal central chitinous 

 structure). First leg slightly enlarged ; its claw well-developed, 

 but not very large and moving against a short, stout curved 

 spinule. There are a few fine hairs of ordinary type, including a 

 long fine hair near the middle of the dorsal surface, on the first 



Text-figure 23.

tarsus. Three of the hairs are blunt, having the broken-oflT 

 appearance characteristic of certain hairs also present in 

 Tyroglyphid mites. There also seem to be three sensory setie 

 (sinneskolben) on the first tarsus ; the one nearest the distal end 

 is cylindrical, and projects almost at a right angle to the segment ; 

 the other two sensoiy setaa lie parallel to the tarsus, one of them 

 being stout and club-shaped, the other slender and difficult 

 to see. Tarsus of second leg with a slender sensory seta 

 (sinneskolbe) similar to that present on the first tarsus ; there is 

 also a strong dorso-lateral spinule on the second tarsus (see text-' 

 fig. 23 5). 



Length of body (including capitulum) 267 /x; its width 135/^,.
