64 REV. J. E. HULL ON 



Berlese includes Halbert's species under Zasiosems, 

 from which they differ in chaetotaxy and form of 

 ambulacrum. Hairs of dorsum all fine and short. 

 Caruncle of three spreading acute lobes (indicating 

 a partly aquatic habit). 



1. Anal scutum ($) sub-circular ... ... ... serratns. 



,, much wider than long ... ... 2 



2. Lateral scutum inflexed behind coxa iv. ... ... tcimipcs. 



,, not inflexed (obliquely truncate) ... it aliens, 



8i. Episeius serratns, Halb. 



Ireland, in sphagnum. 



82. Episeius tenuipes, Halb. 



Ireland, from moss on a stone in a mountain stream. 



83. Episeius italicus, Berl. 67. 



Ovingham (R. S. B.). West Allendale. 



Yorkshire (W. P. Winter). Ireland, in moss, one $. 



AMEROSEIUS, Berl. 



Type : hirstitus, Koch. 



Body broad oblong. Dorsal setae spiny long in a 

 single lateral series, marginal behind, 2 or 3 in 

 front (immediately behind the shoulder) sub- 

 marginal. Cuticle smooth. 



*^* In Berlese's sub-division of this I cannot follow 

 his distribution of species, and I drop Zercoseins, 

 which is simply Lasioseius with crassate setae. 

 And there seems to be no alternative but to 

 institute Zercoiwpsis for remiger and niiinitus. 



84. Ameroseius hirsutus, K. 66, 67. 



Marsden, Chopwell (R. S. B.)) West Allendale. 

 Cheshire, Ireland. 



85. Ameroseius ingens, sp. nov. 67. 



Body somewhat quadrate ; dorsum finely and con- 

 spicuously reticulate, but quite smooth. Very 

 considerably larger than iiirsutus, and the dorsal 

 spines are similarly placed, differing only in size. 



West Allendale, a single specimen (?) in moss.
