COLLEMBOLA AND THYSANURA FROM "CLYDE" AREA 155 



As usual, I am indebted to Mr. Carpenter for kindly 

 going over the specimens and verifying my determinations. 



COLLEMBOLA. 



Fam. SMINTHURID^:. 



Sminthiirus viridis (Linn.). Elvanfoot, fairly common, September 

 1900; Lanark, October. 



S. novemlineatus, Tib., var. insignis, Reut. Common on herbage 

 about pools on a moor near Elvanfoot, September. 



S. bilineatus, Bourl. Elvanfoot and Leadhills, a few specimens off 



heather, etc. 

 S. luteus, Lubb. Elvanfoot, a few specimens off bracken at the edge 



of a wood. 

 S. quadrilineatus, Tib. Three examples (typical), under pieces of 



wood lying on grass at the side of the Clyde at Elvanfoot, 



3oth September 1900. 



S. mahngrenii, Tib., var. elegantulus, Reut. - - This exceedingly 

 minute and interesting form was common on mossy pools 

 on a moor at Elvanfoot in September last. 



,5. ctzcus, Tib. On 8th September 1900 I found six typical examples 

 of this blind species in a nest of the common ant, Myrmica 

 rubra, under a stone at about 1200 feet elevation on a hill- 

 side a mile or so east of Leadhills. They were all more or less 

 marked with red dots. The occurrence of S. ctzcus in this situa- 

 tion is of considerable interest, seeing the only previous British 

 records are from caves at Mitchelstown, Ireland, and near Edin- 

 burgh ; while abroad it is got under flower-pots. 



Papirius cursor, Lubb. Douglas, November, 1900, a few; The 

 Newton, Elvanfoot, etc. 



P. ornatus (Nic.), Lubb. Carluke, Cleghorn, Douglas, Elvanfoot. 

 Abundant in woods. 



P. minutus (O. Fab.). Cleghorn ; near Elvanfoot, among grass, 

 rather common. 



Fam. ENTOMOBRYID^. 



Tomocerus plumbeus (Linn.). Peaton, Loch Long, several examples, 

 June 1900; Douglas, November. 



T. tridentifcrus (Tib.) -- Peaton, Carluke, Lanark, Douglas, 

 Elvanfoot. Abundant. 



Lcpidocyrtus lanuginosus (Gmel.), Tib. Peaton, Cleghorn, Douglas, 

 Elvanfoot, etc. Abundant everywhere. 



L. cyaneits, Tib. Ardpeaton, Loch Long, a few under flower-pots.
