of interest in the entomology of the area, taken in conjunction 

 with the previous work of which I have given a brief sketch, 

 may best be told by a short statement under each of the orders.^ 

 Apteea (Collembola and Thysaxura). — Some ten or 

 twelve years ago I found these lowly and much neglected 

 insects, the Spring-tails and Bristle-tails, beginning to claim 

 my attention, and having persuaded Professor Carpenter of 

 Dublin to help me with the determination of my captures, 

 material for a list rapidly accumulated. The results of our 

 labours were embodied in a joint paper communicated to this 

 Society in 1899, and, as regards a few additional species, in 

 a subsequent paper submitted in 1904.- Adding Isotoma 

 minuta, TuUb., of which I detected a few specimens among 

 Collembola from Edinburgh water-cisterns, submitted to me 

 by Dr Traquair in December 1905/ and a Tetmcantliella 

 from Ben Ledi in Sept. 1906, the list now stands thus — 

 Collembola 63, and Thysanura (excluding one or two recent 

 introductions) 4. About a score of the former were additions 

 to the British list. 



Oethoptera. — The cockroaches, earwigs, and grasshoppers 

 are poorly represented here, numbering, as far as we know, 

 only a dozen species, and some of these not indigenous, 

 though more or less established. A list of our Orthoptera 

 will be found in a paper of mine in the Annals of Scottish 

 Natural Eistorij for 1901.^

 graphy is an impossibility here.

 species, see my further paper published in a subsequent part of this vol., 

 where some additional Collembola, bringing the number up to 66, are recorded.

 in Edinburgh, printed in March 1906. The commonest form, by far, was 

 Isotoma fimetaHa (L. ), TuUb.

 Bavelaw Moss, Aug. 1901, and nr. Glencorse Reservoir, Pentlands, Sept. 

 1904. Labia minor, it may be mentioned, was common at Pettycur, Fife, 

 flying in the sunshine, in July 1901, and G-ryllus doniesticus in a quarry 

 near Slateford in June and July 1907 [A. S. X. H.., 1907, p. 250).
