Collembola and Thysanura of the Edinhiirgh District. 223 



Our list includes four species of Thysanura and fifty-nine 

 of Collembola.^ Eeuter's list (12) of species obtained by him 

 in Scotland enumerates only one Thysanuran and twenty- 

 one Collembolans. Four of these latter, however, namely — 

 Entomdbrya lanuginosa (N"ic.), Isotoma cceca, Eeut., /. crassi- 

 cauda, Tullb., and Anurida crassicornis, Kent., have not been 

 detected by us near Edinburgh. Eegarding /. cceca and A. 

 crassicornis, we would remark that they were new to science, 

 and have not since been met with anywhere. The descrip- 

 tions are unaccompanied by figures, and unfortunately, as 

 we are informed by Professor Keuter, the types have been 

 lost. So little is said by Lubbock as to the range of 

 species in the British Isles, that it is impossible to state with 

 certainty how many of the forms entered in our list are new 

 to Scotland. His detailed localities refer almost exclusively 

 to England — he only twice or thrice uses the term " Great 

 Britain," and only once mentions a Scottish locality, namely, 

 St Andrews. It would seem, therefore, that he had practi- 

 cally no information regarding the group from north of the 

 Border, and that we may fairly claim as first Scottish records 

 nearly all those concerning forms not mentioned by Renter. 

 But be this as it may, we have the satisfaction of introducing 

 at least seventeen species^ new to the fauna of Great Britain, 

 namely — Sminthurus novemlineatus, TuUb., >S^. hilineatus, 

 Bourl., S. violaceus, Rent., S. igniceps, Eeut., S. malmgrenii, 

 Tullb., S. ccecuSj Tullb., Pseudosinella cavernaritni (Mon.), 

 Entomohrya marginata (Tullb.), Isotoma maritima, Tullb., 

 /. grisescens, Schaff., /. sensihilis, Tullb., /. cinerea (Nic), 

 I.fimetaria (Linn.), /. spitzhergenensis, Lubb., /. schoiti, D. T., 

 Xenylla. humicola (0. Fabr.), and AcJioriites longispinus, 

 Tullb. The majority of these are characteristically northern 



1 The number of Collembola in the list when submitted to the Society 

 in February 1899 was forty-eight. Five additions, namely — Sminthurvs 

 malmgrenii, S. coecus, Pseudosinella cavernarum, Achorutes longisjnniis, and 

 A. manubrialis were subsequently reported at the April meeting ; and these, 

 together with six others since discovered, namely — Sminthurus novemlineatus, 

 S. hilineatus, S. quaclrilineatus, S. igniceps, Lepidocyrtus curvicollis, and 

 Tricena mirahilis, are now incorporated in their proper places. 



^ Three of these — Sminthurus ccecus, Pseiulosinella cavernarum, and Isotomoj 

 schUti, have, however, been recorded from Ireland by Carpenter.
