226 The Irish Naturalist. [Sept., 



wbich I called Sinella cavernicola, Mr. Jameson found only 

 three or four specimens. These are in much better condition 

 than my types and it is evident that the species is scaled, not, 

 as I supposed, destitute of scales. It is therefore not a Si^iella 

 and must be transferred to Templeto7iia, I may perhaps be 

 forgiven for not having seen the scales which had been rubbed 

 off, but I certainly should not have overlooked the proportions 

 of the abdominal segments which I figured. Unfortunately I 

 had not examined many springtails at the time, and I did not 

 appreciate the importance of this character in the discrimina- 

 tion of genera. 



A large number of white springtails, which I, at first, 

 believed to be the young of Templctonia caverjiicola, were 

 collected by Mr. Jameson. Detailed examination has, how- 

 ever, shown that these represent a species new to the fauna of 

 Mitchelstown cave and probably new to science. They are, 

 I believe, referable to the genus Cyphoderus, but closely 

 approach a French cave-species Seira cavernarurn^ recently 

 described by Moniez (8) from the cavern of Dargilan, which 

 according to that author might almost as well be placed in the 

 Cyphoderus. But they differ sufficiently from his description 

 to make a new name advisable, and I have pleasure in dedi- 

 cating the species to the intrepid French explorer, M. Martel, 

 whose journey through Ireland has done so much to arouse 

 interest in the caves of our limestone districts. 



Mr. Jameson has himself recorded (2) the occurrence in the 

 cave of Tomocems trideiitiferus^ Tullberg {phimbctis, I^ubbock) 

 which was found there by Messrs. Wright and Haliday. 

 Among his numerous specimens of Lipnra Wrightiiy I now 

 find a few examples of three other species, which, like the 

 Toinocenis, are not typical cave-insects. These are Achorutes 

 armatus, Nicolet, Anwida granaria^ Nicolet, and S7ny7ithu7'us 

 coectiSy Tullberg. The last-named species is a minute, white, 

 eyeless springtail, which, though found in flower-pots on the 

 Continent, should be quite at home in a cave. It does not 

 seem to have been hitherto observed in the British Islands. 

 Altogether, therefore, we are now able to record seven species 

 of Collembola from the cavern of Mitchelstown. It remains 

 to deal with each species in detail.
