Collembola and Thysanura of the Edinburgh District. 235 



Braid Hermitage, Eosslyn, Penicuik, and Ravelrig, Oct., common; 

 Corstorphine Hill, Ratho, and St Margaret's, near N. Queensferry, Nov., 

 common ; Yogrie (Midlothian), Feb., and Dollar (Clackmannan), April 

 1897, common ; near Kirkliston, Binny Craig, and Carribber Glen (Linlithgow), 

 March 1898, a few; wood near Polton (Midlothian), April, many, of all ages, 

 from the pale tiny young to the dark well-marked adults ; Bridge of Allan, 

 Feb. 1898, several, some small ; Bucklyvie (Stirlingshire), April 1896, a few ; 

 Aberfoyle (W. Perth), April 1896, abundant ; Dalmeny Park (Linlithgow), 

 Feb. 1899, abundant; Aberdour (Fife), Feb., a few, of pale variety; etc. 



Papirius minutus (0. Fabr.). 



Papiriics nigromaculatus, Lubbock's "Monograph." 



Typical examples of this form, which appears to be much 

 better known on the Continent than the last-mentioned, 

 being on record for Norway, Sweden, Finland, Germany, 

 Austria, Italy, Sardinia, etc., are by no means common 

 about Edinburgh. In England it is, according to Lubbock, 

 plentiful in Kent during the spring and summer months. 

 In our experience it is more of a summer insect than 

 F. ornatus, and frequents opener grassy places. 



Local data.— Banks of Braid Burn below Comiston, end of July 1896 and 

 3rd Aug. 1898, a few along with the preceding ; in garden, Morningside 

 Park, Edinburgh, 17th and 18th July 1896, fairly common ; Ui.hall, Sept. 

 1896, several, and Aberfoyle, a few ; Torphin, March 1899, one ; near Mid- 

 calder, May, three; Inverkeithing, June, a few ; Longniddry, Aug., one. 



Family ENTOMOBRYIDiE. 



Genus Tomocerus, Nicolet. 



Tomocerus plumbeus (Linn.). 



2'omoccnis longicornis, Lubbock's " ^ronogra})h." 



Though common in England and Ireland, this species 

 appears to be much less frequent in the Edinburgh district 

 than some others of the genus. At any rate, we have as 

 yet detected it in very few localities, and (apart from the 

 structural differences revealed by the microscope) it is not 

 difficult to recognise even in the field, by, among other 

 things, its relatively pale leaden line. Our common species, 

 2\ tridentiferus, for instance, has usually a decidedly darker
