Prof. Moniez in the deepest part of the great cavern of 

 Dargilan, in the south of France (9). 



How this typical cave- species comes to be in so com- 

 paratively shallow and recent an excavation as the quarry 

 at Moredun, is a rather perplexing problem. The idea of 

 recent independent development there is out of the question. 

 In all probability it existed in holes and crevices in the 

 rocks ages before the quarry was begun. 



[Since the above was written, Dr Schaffer, having seen 

 one of our specimens, has drawn our attention to the apparent 

 identity of our insect with the Tullhergia immacidata of 

 Lie-Pettersen, recently described (6), from Norway, where it 

 occurs under stones among loose earth in cultivated places.^ 

 Irish examples of our insect having been pronounced by 

 Professor Moniez the same as his Sira cavernarum, we feel 

 bound to accept his identification.] 



Local data.— Old limestone-mine, Moredun Mains, near Gilmerton (Mid- 

 lothian), fairly common under stones in April and May 1899. 



Genus Seira, Lubbock. 



Seira buskii, Lubb. 



Occurs sparingly under or about flower-pots in green- 

 houses in the Morningside district of Edinburgh, and doubt- 

 less in like situations in a number of other localities ; but 

 we have not yet discovered any outdoor habitat for it. This, 

 however, does not necessarily imply that it is a foreign 

 importation, for along with it we find truly indigenous 

 species, such as Tomocerus tridentiferus, Entomohrya multi- 

 fasciata, and Lipura armata. 



Its known range extends from Scandinavia to Italy, and 

 from England to Hungary and even Siberia. 



Local data. — Greenhouses, Morningside, Edinburgh, February, March, 

 and April 1899, about a dozen specimens. 



^ A specimen of the Norwegian insect has since been Idndly sent to us by 

 Mr Lie-Pettersen : it is undoubtedly of the same species as our insect. The 

 generic name {Pseuclosinella) proposed by SchJiffer (14) in place of Tullbcrgia 

 (preoccupied) has priority over that (Pettcrsenia) proposed by Scherbakow 

 ("Zoologischer Anzeiger," 1898). We think it very likely tliat this species 

 may ultimately prove to be BccJda argentea, Lubb.
