BBYOCOMS PTEBJDIS Fall. 



This species is said to be attached to the common bracken, 

 but I have never seen it upon that fern. It is, however, com- 

 mon in many places upon Athyrium filix-famina, Lastreafilix- 

 mas, and L. dilatata. It may be found from July to September. 

 The majority of examples are undeveloped, the wings-cases 

 having neither cuneus nor membrane. Developed individuals 

 are very rare, but I found three in Kirkcudbrightshire, which are 

 the only developed specimens that I have seen. 



AGALLIASTES WILKINSONI D. & S. 



This species was described for the first time in 1866, and 

 named in honour of its discoverer, who found it by searching 

 among moss at the roots of Maianthemum bifolium, near 

 Scarborough. It was supposed to be attached to this plant, 

 which is rare in a native state in Britain, but it seems to have 

 no particular connection with it or any allied plant. I do not 

 remember seeing any record of its having been found elsewhere 

 in England, but in Scotland it seems widely distributed, though 

 local. Sandy, dry ground, covered with very short grass, 

 thyme, and other plants, seem the especial haunts of the 

 species; and in such places, in June and the beginning of 

 July, I have taken it in Inverness-shire, Aberdeenshire, and 

 Kirkcudbrightshire. It is somewhat difficult to catch, from its 

 active leaping habits, but by sweeping with a net a series may 

 be easily obtained. It attains an elevation of 1,100 feet. 



TERATOCORIS VIRIDIS D. & S. 



This species was first taken near Loch Rannoch, and was 

 described from a single specimen (male) in 1S67. I do not 

 think that the female has been described, I therefore proceed 

 to describe it now. 



Developed form : shape as in the male, but larger and 

 stouter. Colour green, with a fine black central line extending 

 from the front of the head to the apex of the scutellum. The 

 two last joints of the antennne pale piceous. Inner margin 

 of the clavus narrowly black. Membrane with two cells, of 

 which the lesser is very small and narrowly triangular. Apical 

 half of the third joint of the tarsi blackish. 



Undeveloped form : similar to the developed form, but without
