WOMERSLEY—AUSTRALIAN ACARINA 223 
Legs short, tarsi with 3 claws, of which the median (empodium) is stronger than 
the others. 
Loc. Two specimens from moss from Mt. Arden, 12 miles north of Quorn, 
S. Aust., Nov., 43 (H. M. Cooper) ; also six specimens from debris from under 
tree ferns, Waterfall Gully, 8. Aust., 5/35. (R.V.S.). 
Remarks. In the structure of the hairs, particularly those on the cephalo- 
thorax, these specimens agree with Berlese’s figure (loe. cit.) of C. plamatus, but 
Berlese states that his species differs from the genotype C. lanatus (Mich.) in the 
hysterosoma in the ‘‘euticle not scabrous, reticulate or otherwise impressed.’’ The 
South Australian specimens are definitely ornamented on the hysterosoma (ef. 
fig. 2A), but otherwise agree entirely in the strueture of the hairs with Berlese’s 
very fine detailed figure. In Michael’s figure of lanatus (Brit. Orib. II, pl. 
XLIX, fig. 15), the hairs are shown as very different, especially the lamellar hairs, 
while the ciliations of the long hysterosomal hairs are scarcely longer than the 
width of the main stem. 
It seems therefore that these specimens must be referred to a variety of Ber- 
leses’ species with the dorsal cuticle having impressed pits.
