SYNOPSIS OF THE BRITISH PHRYGANID^. 83 



a third, of the same size, is situated upon the thy- 

 ridium ; externally, close to the anastomosis, in the 

 bases of the apical cells, there are six pale spots, two 

 of which are close together in the third apical cell ; 

 veins slightly clothed with dark hairs ; posterior 

 wings smoky grey, with the apex brownish. App. 

 sup. $ finger-like, bent upwards; between them the 

 posterior margin of the last segment is produced into 

 a roundish process (Brauer, N. A. fig. 81 [ ? ]). 

 This species also varies considerably; in the males 

 the pale spots of the anterior wings are usually en- 

 tirely wanting ; the females are sometimes very similar 

 in colouring and marking to the males of L. griseus, 

 and Stephens has mixed the two species in L. sig- 

 natus.

 Yellowish grey ; body brownish, the antennas with paler 

 rings; anterior wings ochreous, somewhat brownish, 

 clothed with light yellow hairs ; pterostigma pitchy 

 brown ; a brown longitudinal dash, sprinkled with 

 paler points, reaches from the base towards the anas- 

 tomosis, but is usually (like the narrow, oblique 

 fenestrated spot) only distinct when the wings are 

 closed ; the veins of the anastomosis brown, the 

 longitudinal veins spotted with brown and yellow,
