252 C. D. SOAR ON ECPOLUS PAPILLOSUS. 



conspicuous, and all have a hair growing from near the base. 

 There are more of these towards the posterior margin of Ecpolus 

 2)apillosus than on other parts of the body. In Ecjyolus tuber atus 

 the projections are mostly round the margin of the body, the 

 central portions of the dorsal surface being entirely free from 

 them. 



The legs (first, 0*40 mm. ; second, 0'53 mm. ; tliird, 0*56 mm.) 

 and epimera exhibit nothing uncommon, being very much the 

 same as we find in Fiona and some other genera. 



The genital plates are quite different to those of Koenike's 

 Ecpolus tuheratus. In the latter the genital discs are free on 

 the surface skin, but in this mite the genital discs are on special 

 plates (see fig. 3), and they stand up in relief. 



I hope during this coming season that Mr. Taverner, or some 

 other member of the Club, may be so fortunate as to find some 

 more specimens, including the male.
