(Nethy Bridge), but stiJl not a common species, and 

 apparently a frequenter of fresh water for preference. 



7. H. borealis Lw. : not uncommon at Rannoch, Braemar, Nethy 



Bridge and Golspie, and therefore probably over all the 

 Scutch Highlands. The upper part of the face is usually 

 described as " tarnished," but to me the distinction is but 

 slight on the whitish face of the male or on the orange face 

 of the female. 



8. H. rujibarbis Gerst. : I am compelled to assign this name to a 



male taken at Callater, near Braemar, on July 20th, 1873, as 

 it certainly does not belong to any other known European 

 species. I believe I caught it on the little stream which 

 crosses the path just before the loch when approaching from 

 Braemar. Gerstaecker described the species in 1864 from a 

 female taken near Berlin and a male taken near Stettin, but 

 it seems to have not been noticed since by anybody. 



9. R. nebulosus Fin. : I have taken this very distinct little species 



in some numbers in the New Forest, at Reigate in Surrey, 

 and at Lairg, while Col. Terbury found it in numerous locali- 

 ties in North Scotland in 1904, 



29. LIANCALU!S Lw. 



1 (2) Legs all black ; scutellum with six bristles ; wing ( J ) snow-white at tip... 



1. virens Scop. 



2 (1) Legs black, with yellow knees and joints ; scutellum with four bristles... 



2. lacustris Scop. 



1. L. virens Scop. : common wherever water trickles down a perpen- 



dicular surface, from Cornwall to Sutherland. 



2. L. lacustris Scop. : much rarer than the other species, and I only 



know it from Hampshire, Sussex, and Suffolk. The genus 

 Alloeoneurus is not worth adoption. 



30. CAMPSICNEMUS Walk. 



1 (14) Legs peculiarly formed or adorned (slight in C. pectimilatus) ; antennae 



not pale at base. 



2 (3) Only front legs peculiarly formed ; middle legs simple ; front tarsi with 



extraordinai'y split up processes 1. magius Lw. 



3 (2) Middle legs peculiarly formed or adorned, and sometimes front legs also. 



4 (5) Front tarsi dilated at tip ; face and postocular cilia black ; middle 



femora and tibiae finely ciliate and pectinate 2. pusillus Meig. 



5 (4) Front tarsi not dilated at tip ; lower postocular cilia pale. 



6 (11) Basal joint of middle tarsi much shorter than second joint (only a little 



shorter in C. loripes).
