TWO RARE WOODLICE FROM THE FORTH AREA 39 



habitat, and I recently searched both Polystictus and Corticium in 

 Gibside, taking two more examples of propinqnns, both from under 

 Corticium. 



Hoodia dagfiai/i, Karny. 1 — Mr Evans has sent me examples of 

 this large and fine species from under Elm leaves, Dalmeny Park, 

 Linlithgowshire, July 1909. My original specimens were taken in 

 Teesdale and Derwent Valley, Co. Durham, and I have recently 

 received specimens collected by Father Longinos Navas, in Spain. 

 The species agrees very well with Uzel's description of Liothrips 

 hradiceftsis, under which name I first recorded it. Prof. Karny of 

 Vienna, however, has had the opportunity of examining Prof. Uzel's 

 unique example in the Vienna Museum, and shows that my specimens 

 differ structurally in the form of the mouth, and in the presence of 

 certain bristles. The importance of the chaetotaxy in the Thysan- 

 optera was not realised when Uzel's work was written in 1895.

RECORDS OF TWO RARE WOODLICE 

 FROM THE FORTH AREA. 



By Richard S. Bagnall, F.L.S. 



As the following Woodlice are not only regarded as some- 

 what rare (though I have found them to be widely distri- 

 buted), but have not apparently been recorded from the Forth 

 Area, I think their occurrence within that area worthy of 

 note : — 



Trichoniscid^e. 



Trichoniscus pygmceus, G. O. Sars. — Some years ago I met with 

 a single example in the gardens behind Regent Terrace, Edinburgh. 

 This autumn (19 12) Mr W. Evans and I found it in a quarry near 

 Swanston, at the foot of the Pentlands, where it ultimately proved 

 to be plentiful. We also took a few examples on Arthur Seat whilst 

 collecting Scolopendrellidce. Mr Evans informs me he obtained it 

 in 1907 at the Botanic Gardens, Edinburgh. 



Haplophthalmus mengii, Zadd. — This sluggish form, which 

 generally harmonises wonderfully with the stone to which it clings, 

 is probably often overlooked.
