damp. There is great variation in colouring, especially in the 

 females, there being often a striking similarity to that of the 

 environment — a feature which should l^e of much advantage to an 

 insect whose movements are rostricted in consequence of its aborted 

 alar organs. I have met with it in Surrey as late as October 12th. 



Gomphocerus rufus, Linn. — Again we have two congeneric 

 species, G. nifus and (Jr. iiutcnlatns, which, though bearing some, 

 resemblance one to the other, are readily distinguished from all the- 

 rest of the British Acridiodea by the possession of clubbed antennae.. 

 Burr considers Li. rufus " common in north and central Europe," 

 but it does not appear to be so in England, where I have only a few 

 records for the south. They are: — Kent: Folkestone Warreu. 

 (Burr); Maidstone (Shaw). Snrreij: Compton (F. W. Edwards);. 

 Boxhill (Briggs) ; Leatherhead (Burr) ; Battersea Fields, taken in 

 the nineteenth century by Samouelle (Dale) ; Eedhill (Frisby) ; 

 Bookham Common (Lucas). Snsse.r : Linchdown and Goodwood 

 (Guermonprez). Hants: Lyndhurst (Dale). Berka : (Hamm). 

 (jrlouce.ster : Colesbourne (J. Edwards). Devon: Wembury and 

 Bolthead (Bignell) ; sandhills at Exmouth and Dawlish (Parfitt). 

 I have no records at all for Scotland, Ireland, or Wales. 



My sole experience of the species — on the dry warm bank of a 

 certain pond on Bookham Common — does not enable me to speak 

 generally of its habitat in this country. Points of distinction from 

 the other species, (r. inacidatus, are (i.) the rather larger size, (ii.) the 

 uniform reddish-brown colour, (iii.) the pronounced clubs to the 

 antenniB, especially in the male, which has them tipped with white. 



Gomphocerus maculatus, Thunb., is a common species in, 

 northern and central Europe, including Great Britain. I have a 

 good number of records for England and Scotland, as well as some 

 for Ireland, Wales, and the Isle of Man. It seems to be most 

 at home on heaths and other dry places. (r. maculatus is very 

 variable in colouring, and usually assimilates remarkably 

 well with its surroundings — almost black examples, for instance, 

 being found on a recently burnt heath. In Surrey it is usually 

 mature towards the end of June. Distinguishing points are : (i.) 

 the small size, (ii.) the spotted appearance, (iii.) the antennae 

 without white tip. In the female the clubbing of the antennae is 

 not very evident on a superficial examination. 



Tetrix bipunctatus, Linn. — To conclude with, we have two 

 very small gras>hoppers with inordinate extension backwards of the 

 pronotum, though in the British species this is nothing compared 

 with the size and extraordinary shape assumed by some exotic 

 species. .'/'. biiiunctatus is distributed all over northern and central 

 Europe, and is very common in Great Britain. I have many 

 records for England and Scotland, and some for Ireland, Wales, 

 and the Isle of Man. It is a very variable species, not easily dis- 

 covered when at rest. Eland Shaw gives "dry places in woods, 

 fields, and under dead leaves " as its haunt, but I fancy it is not
