GOMPHOCERUS RUFUS. 219 



front of the cross furrow, which is about half-way 

 between the front and hind margins : usually two longi- 



O .' 



tudinal black lines interrupted by the oblique lateral 

 caringe. Elytra (PI. XX, fig. 2) well developed, almost 

 uniform pale brown ; costal nervure arched near the 

 base ; area between costa and first sub-costa extending 

 three-quarters of the elytron. Wings fully developed, 

 tinged with brown towards the apex. Abdomen yellow 

 below. 



FEMALE IMAGO (Plate XXIII, fig. 4). Colour much 

 as in the male. Length 17-20 mm. Antennde shorter, 

 clubs far less pronounced than in the male. Elytra and 

 wings not quite reaching the tip of the abdomen. 

 Valves of the ovipositor short. 



EGG.- -Roughly cylindrical. It is somewhat rounder 

 at one end, while the other turns slightly to one side. 



o / 



Length 4 mm. It appears to be not quite circular in 

 section, the width in one direction being 1 mm., at 

 right angles to it O9 mm. The examples examined 

 were extracted from a dead female and put in weak 

 spirit, so the natural colour is uncertain. The surface 

 was a little wrinkled transversely, but this was perhaps 

 due to the spirit. 



VARIATION.- -Cr. rufus seems to be rather constant in 

 its colouring. In each sex there may be a cream- 



o i 



coloured mid-dorsal stripe on the thorax. 



DATE.- -August and September seem to be the months 

 when this grasshopper may most certainly be found 

 mature ; but Chapman has taken it in Surrey as late as 

 31 October. I mio-ht add that I have found nymphs.

also in Surrey, as late as 9 September. 



HABITS, ETC.- -Dry grassy banks, grassy hill-sides, 

 clearings in woods, and similar spots seem to consti- 

 tute the habitat of this grasshopper. Where it occurs 

 the clubbed antennae- -dark club with white tip- -are 

 quite easily noticed, especially in the male, though the 



rather short elvtra of the female are inclined to suo-o-est
