Gainasus (Ologamasus) pollicipatus Berl. 



A female Ologamasus found amongst moss on Clare Island is probably to 

 be referred to the present species. 



The genital area of this specimen does not agree very well with Berlese's 

 figures of the typical form, but resembles more closely that of the variety 

 excvpuliger. The species must be recorded witli reserve until male examples 

 are found. 



Gamasus (Ologamasus) inornatus Berl. 



Found amongst moss on Clare Island in March. 



Berlese does not attempt to tabulate the females of Ologamasus, but the 

 present species is mentioned on account of the simple structure of the 

 endogynium. In the other known species the females have this structure 

 more or less elaborated.

Westport, a single specimen in the coleoptrate nymph stage found attached 

 to a ground beetle ( I'terostichus niger). 



The genus Boecilochirus contains a few species of acarina which were 

 known only as nympha coleoptrata, or mites in the wandering nymphal stage. 

 The essential characters of Berlese's account of the genus, originally described 

 by Canestrini, are as follows : — " Mandibulae digitus fixus saepius apophysi 

 hyalina anterius porrecta auctus. — Corniculi labiales aliquando curtiores, 

 forcipem quasi cum malis maxillarum interioribus sistentes." (1, Fasc. lxx, 

 n. 11.) 



In the same reference Berlese characterizes another genus, Iphidosoma, 

 for certain species of Boecilochirus, which was also based on immature forms, 

 and in a later work (2, p. 73) his arrangement of the species is as follows : — 

 Poecilochirus carabi Can.; P. spinipes Koch ; P.iiiterrwptuslLoch.', Pphidosoma 

 fimetarium Can. ; /. ovatum Berl. 



The genus Gamasoides was proposed by Berlese in 1903 (6, p. 280), with 

 G. carabi Canestrini as the type species. 



Gamasoides spinipes (C. L. Koch).
