﻿Collemhola and Thysanura from the Forth Area. 195 



XVIII. Some further Records of Collemhola and Tliysanura 

 from the Forth Area. By William Evans, F.E.S.E. 



(Read 23rd March 1908.) 



The main object of these notes is to put on record a 

 number of fresh localities within this area for some of the 

 less common Collemhola or Spring-tails included in the paper 

 on the group by Professor G. H. Carpenter and myself, 

 published in 1899 in the Proceedings of this Society.^ Most 

 of these localities, it will be found, carry the distribution of 

 the species to which they refer into fresh counties, and all 

 the records, I may say, are based on my own observations. 

 Including Isotoma minuta, Tullb., and the Tetracanthella, 

 which are interesting additions to our list, there are now 

 63 species of Collemhola known from the Forth area. 



COLLEMBOLA. 



Sminthurus hortensis, Fitch. — Otterston, Fife, July 1901, 

 a few specimens taken on footpath. My previous localities 

 for this species in " Forth " were all in the Lothians. 



S. hcteus, Lubb. — Further localities for this species are 

 Blair Adam, near Kinross, June, and Castle Campbell, near 

 Dollar, July 1901. 



S. violaceics, Reut. — On footpath, public road, at Otterston, 

 Fife, July 1901, six specimens secured. Isotoma palustris, 

 var. maculata, also occurred on this footpath. 



S. malmgrenii, Tullb., var. elegantulus, Eeut. — In Oct. 1902 

 this pretty little form was met with in some numbers on 

 peat pools near the top of Lammer Law, Laramermuir Hills. 

 In Feb. 1900, Dr Folsom, of Cambridge, U.S.A., wrote me 

 that his aS^. socialis is identical with this form, specimens of 

 which I had sent him for comparison.
