PHOLtDOPTERA GRISEOAPTERA. 



pale line; elytra yellowish, wrinkled, scale-like, not 

 half the 'length of the abdomen; -wings absent; fore 

 and mid legs of moderate length, hind legs very long 

 (some 43 mm.) ; femora unarmed, mottled, hind ones 

 much swollen at the base ; fore tibiie with, three spines 

 above, hind tibiae with four apical spurs below ; first 

 tarsal segment with pronounced free plantules. Abdo- 

 men brown above and somewhat mottled, vellow below ; 



' V 



cerci conical, straight, hairy, with an internal tooth 

 near the base ; subgenital lamina yellow, styles short. 



FEMALE IMAGO (PI. XV, fig. 2).- -Larger (15 to 

 18 mm.), but in colour much resembling the male. 

 Elytra lateral, reduced to tiny scales, only just pro- 

 jecting beyond the pronotum ; dorsal surface of the 

 pronotum more rounded than in the male ; posteriorly 

 a median carina indicated (perhaps more clearly than 

 in the male). Ovipositor long (9 to 10 mm.), smooth > 

 rather broad, curved well upwards, sharp-pointed. 



NYMPH.- -In appearance much resembling small 

 adults, the elytra-scales gradually developing as the 

 nymphs approach maturity. The colour is perhaps of 

 a rather more uniform greyish tint. Burr remarks 

 that the abdomen is sometimes green. 



VARIATION, ETC.- -There is some difference in size, 

 though not of a very noticeable character, and occa- 

 sionally individuals are met with of a rather darker 

 tint than the normal; but the species with us is not a 

 variable one. Bracken took one of a distinctly reddish 



/ 



chestnut colour at Woolacombe in Devon. A male, 

 taken by F. W. Terry near Wimbledon in August 1901 , 

 besides the normal pair of auditory organs situated at 

 the basal extremity of the fore tibiae, had a pair on the 

 mid tibias also. Their position and external appearance 

 were quite normal, so presumably they were functional. 

 The abnormality was unnoticed till the insect had 



/ 



been killed, so it w~as impossible to test its power of 

 responding to sound by means of these additional 

 tympana. Other males appeared to answer one
