this form, which is common in North and Middle Europe, 

 and has also been recorded from Greenland, Siberia, and 

 Chili. 



Local data.— Swanston, March 1896 ; Bavelaw, under, stones and pieces 

 of wood, March 1897, etc., common ; Mortonhall, May, common ; North 

 Berwick, Aug.; Carribber, March 1898; Edgelaw, Oct.; Buckstone, Nov.; 

 Craigentinny Meadows, under logs, Feb. 1899, abundant ; Morningside, 

 under boards and flower-pots in gardens and greenhouses, Feb., March, and 

 April, common; Aberdour, Feb., a few; etc. 



Lipura ambulans (Linn.), TuUb. 



Widely distributed and apparently common, but to 

 separate it from the previous form entails a very careful 

 microscopical examination of every specimen : occurs chiefly 

 among damp earth and leaves, and on the under sides of 

 stones and pieces of wood lying on damp ground. Probably 

 ranges throughout Europe — Dr Schaffer, however, tells us 

 he has not yet found it in Germany. 



Local data.— Arthur's Seat, and near East Calder, Feb. 1896; Dreghorn, 

 March; Comiston, July, a few; Gladsmuir, Sept.; Braid Hermitage, Oct., 

 under dead leaves; Rosslyn, Abercorn, North Queensferry, Oct. and Nov., 

 Vogrie, Feb. 1897 ; Balerno, two, Aberdour, a few. Dollar, April ; Bridge 

 of Allan, Feb. 1898 ; Whitehill (Midlothian), Binny Craig, March; Morton- 

 hall, March 1899 ; Morningside, in greenhouse, March ; Moredun limestone 

 quarry, April, several. 



Lipura fimetaria (Nic, 1847), Lubb. 



Lipura inermis, TuUb. 



[Plate VIII. Fig. 24.] 



This species is common under flower-pots, etc., in gardens 

 and greenhouses in the southern suburbs of Edinburgh, and 

 no doubt in many other localities in the district. Drs 

 Schaffer and Folsom (5) have recently come to the con- 

 clusion that Lipura fimetaria, Lubb., and L. inermis^ TuUb., 

 are specifically identical, a view in which we entirely concur. 

 In 1847 Nicolet, as noted by Lubbock, evidently applied 

 the name fimetaria to the variety with eight elevations in 

 the post-antennal organ ; but it is clear Lubbock himself did 

 not restrict the name to that form, for although his words, 

 " post-antennal organ consisting of sixteen elevations in two
