374 MR. J. N. HALBKRT : NOTES ON A CAM, 
The male of this species has not been described. The general structure 
resembles the males o£ Episeius. Dorsum as in the female. Free chela 
(fig. 14) armed with a long process resembling that of L. (E.) italicus, Berl., 
but shorter and less curved, each chela with one strong tooth, in front of thg 
tooth on the fixed chela is a row of very small teeth. Length of male 484 /j,, 
breadth 352 fi. 
On account of the apparent difl^ereuce in the length of the dorsal hairs in 
the Irish specimens when compared with the published figures (36, Taf. 6. 
fig. 45), I sent drawings to Dr. Oudemans, who informs me that they un- 
doubtedl)' represent L. (P.) subglaber. The dorsum of this species is 
frequently coated with fragments of debris which are entangled between the 
long inwardly-curved marginal hairs, reminding one of what occurs in the 
Oribatid genus Damceus. 
Localities. In sphagnum pools at Lough Atorick, Co. Clare, June, and 
also at Lough Dan, August. Both sexes occurred amongst wet moss 
collected on the bank of a stream at Glencullen in the Dublin Mountains, 
in October, and at Drogheda in August. 
Lasioseius (Leioseius) minutus {Halbt.'). 
1915. Seiulus mmutus, Halbert, 33, p. 76. — 1918. Zerconopsis minutus, Hull, 25, p. 66. 
— 1920. Lasioseius minutus, Berlese, 14, p. 171. 
Hull has j)laced the present species in a new genus Zerconopsis, of which 
the type is Kramer's " Gamasus remiger." Berlese, however, had already 
referred this species to his subgenus Zercoseius (10, p. 33) with S. spatJiu- 
Liger, Leon., as the type. On re-examining the Irish specimens of L. minutus, 
it seems to me they fall readily into Dr. Berlese's subgenus Leioseius, briefly 
diagnosed by him as follows : — " Ex gen. Lasioseius. Pedes breves et robusti. 
Truncus elongatus, lateralibus subparallelus. Typus L. Ij. minusculvs, Berl." 
An estuarine species {L. salimis, Halbt.) of this subgenus occurs on the 
Dublin coast (24, p. 125). 
Localities. Amongst sphagnum collected on Croaghmore Mountain, Clare 
Island, Co. Mayo, and under rotten wood lying on the ground in the Carton 
Demesne, Co. Kildare, May. The male is unknown. 
Seius togatus, C. L. Kock. 
Until recently (1916) acarologists referred species of vei-y different facies 
to Koch's genus Seius. Many new genera and subgenera have now been 
established by Dr. Berlese, so that a great advance has been made. As 
S. togatus is the first species of the genus described by Koch it remains as 
the ty[)e. It is also a very isolated form with but few congenersj three have 
been described from Europe (see Berlese, 11, p. 150). 
Locality. A single specimen found by Mr. Norman Stephens under the 
moist bark of a pine-stump at the entrance to The Devil's Grlen, Co. Wicklow,
