purple lustre about it. T. plumheus has the antennae much 

 longer than the body, whereas in none of the three following 

 forms do they exceed the body in length. The long fila- 

 mentous inferior foot-claw, which is rather longer than the 

 superior one, is also characteristic. On the Continent the 

 present species is widely distributed — Norway and Sweden, 

 Germany, Bohemia, etc., and it has also been recorded from 

 La Plata. 



Local data. — Buckstone, near Ediuburgli, Feb. 1896, several ; marshy 

 spot near Loiigniddry (E. Lothian), Sept. 1897, a few; banks of Braid 

 Burn below Comiston, 3rd Aug. 1898, common. 



Tomocerus vulgaris (Tullb.). 



Widespread and seemingly fairly common in this district, 

 a fact of interest in view of the little that has hitherto 

 been known of it as a British species. It is not mentioned 

 in Lubbock's " Monograph," but Eeuter (12) has recorded it 

 from Shetland, and Brook (1) from Jersey. Apparently of 

 northern distribution ; it has been found in Sweden, Finland, 

 Eussia, Siberia, Germany, Bohemia, and the Tyrol. Like its 

 congeners, it is to be looked for under stones, boards, bark, 

 moss, etc. In living and unrubbed examples the colour is 

 black or purplish-black, with bronze reflections. 



Local data. — Pentland Hills above Boghall (Midlothian), several, and 

 also near Swanston and East Calder, Feb. 1896 ; Mortonhall, Torduff Hill 

 (Pentlands), and Kirknewton (Midlothian), March 1896 ; Gifford (E. Lothian), 

 Sept. 1896, several ; Duddingston Loch, Edinburgh, under boards among the 

 reeds, March 1898, a few ; Bavelaw, under logs, common, March 1899. 



Tomocerus niger (Bourlet).i 



Tomocerus flavescens (Tullb.). 



[Plate YII. Fig. 16.] 



This form is also widespread in the neighbourhood, and 

 appears to be rather more common than the last. It is 

 plentiful in England, but is not mentioned among Eeuter's 

 Scottish captures. On the Continent it ranges from Norway,
