TriclioiuscTis stebbingi Piitience. 



38 



The only Irish, records of this species 

 are from the Botanic Gardens, Glas- 

 nevin, Dublin, where it vas taken in 

 the greenhouses by ilr. E. S. Bagnall 

 in 1908, and on a subsequent oc- 

 casion in the same place by one of us 

 (D.E.P.B.). 



TEICHONISCOIDES. 



The genus Trichoniscoides was created by Prof. G. 0. Sars for the species 

 T. aJbidiis; and he distinguishes it from the genus Trichoniscus by the presence 

 of 3 pencils beliind the cutting part of the left and 2 behind the cutting part 

 of the right mandibles ; whereas in Trichoniscus, these pencils are 2 and 1 

 respectively. Prof. G. Budde-Lund does not, however, recognize this generic 

 distinction, and includes this species in the genus Trichoniscus. It is not for 

 us to say which of these great authorities is correct, so we content ourselves 

 with recording the species under Sars' genus.

The first specimens referable to this 

 species were taken by one of us amongst 

 the shingle on the sea -shore of the 

 Broad Stond, Howth (D. E. P. B.), and 

 it was subsequently found at Eathmines, 



Co. Dublin (N. E. S.}; Claie Island 

 (E.F. S. and X. H.F.), and Louisburgh 

 (A. W. S.), TV. Mayo ; Bundoran, E. 

 Donegal (KH. F.); St. John's Point 

 (A. W. S. and iS^. H. E.) and iN'ewcastle, 

 Co. Down (A. "W. S.). Its capture in 

 Ireland has not been previously 

 recorded. 



In England it has been taken at 

 Eton (Stebbing), and Sunderland 

 (Brady), while ilr. Patience records it 

 fi-om Kew Gardens ; Xewcastle-on- 

 Tyne ; and from many localities in the 

 neighbourhood of Glasgow. 



It occurs in France (Dollfus), Den- 

 mark, and Holland (Budde-Limd), and 

 at Christiania, Norway (Sars). 



HAPLOPHTHALMTJS. 



Only two species of the genus Haplophthalmus are known, and both have 

 been taken in Ireland. They are easily distinguished from each other.
