TETRIX SUBULATUS. 211 



passed over the sun. As they could turn in the air, 

 they were employing their wings for true flight. They 

 did this to avoid some object, or the water, as it 

 appeared, although they seemed fairly well at home in 

 the latter element. They swam quite well, even under 

 the surface, propelling themselves by means of their 

 hind legs. As I had no net, I captured them by hand, 

 but found it a difficult matter to follow them (parti- 

 cularly the small dark males) more especially as little 

 black spiders were running on the ground, little black 

 flies were flitting over it, and other small insects kept 

 rising up from it. I fancy (but am not certain) that 

 when they are followed the flight of these grasshoppers 

 becomes less and less strong. They varied greatly in 

 colour and conspicuousness. In the form with the 

 pale disc on the fore part of the pronotum, var. stylifer 

 Luc., the colouring is really due to the pale tint of the 

 pronotum being interrupted by two large black tri- 

 angular spots, similarly situated to those from which 

 T. bipunctatus derives its name. 



DISTRIBUTION.- -This little grasshopper is widely 

 distributed in Europe England, Holland, Belgium, 

 France. Alps, Pyrenees, and Spain at least. It also 

 occurs in Asia (Kirby). 



BRITISH LOCALITIES. 

 Jude'ino- by the records T. subulatus is an uncommon insect 



p O J . 



in Britain. So inconspicuous is it, however, that it may 

 only be awaiting investigators to put it on a much better 

 footing-. 



ENGLAND. Berks: Neighbourhood of Radley College (Burr). 

 Cambridgeshire : Cambridge (Hope Coll., Oxford) ; Wicken 

 and Burvvell Fens (Horley). Cornwall: Padstow (Lamb); 

 Xewquay (Burr) Widemouth Bay near Bude (Bracken). 

 Devon: Bignall considered that it was generally distributed, 

 but Bracken does not find it so now. He says: " T. bi- 

 jtiuictatus is common everywhere here [presumably near 

 Plymouth] but T. subulatns rarely occurs. Mr. J. H. Keys 

 has given me one taken at Nodder Bridge (near Plymouth 

 but on the Cornish side of the Tamar) 24 April 1915. All
