AT CANNES AND MENTONE IN 1866. 211 



The galls are at first of a fresh healthy green colour, but after- 

 wards change to a pale brown, and the tip has frequently rather a 

 withered appearance. The excrement of the larva is deposited at 

 that end; in the gall which I opened the head of the larva was 

 downwards. 



Gelechia cisti, n. sp. 



Exp. al. 5-6 lin. Head dark grey ; face whitish grey. Palpi 

 with the second joint internally whitish grey (except the end, which 

 is grey), externally grey, with two or three dark grey spots, terminal 

 joint grey, with the base, a central ring, and the tip dark grey. 

 Antennae dark grey. 



Anterior wings dark slaty grey, with three tufts of tawny grey 

 scales near the inner margin; the first (and largest) before the 

 middle, the second in the middle, the third beyond the middle ; an 

 oblique black streak arises on the costa near the base and terminates 

 at the first tuft, and a fainter oblique dark streak proceeds from 

 near the middle of the costa ; on the costa, beyond the middle, is a 

 small blackish spot, below which are two black spots at the end of 

 the discoidal cell, edged externally with pale grey ; a little beyond 

 them a slender black streak proceeds to the apex of the wing ; the 

 apex of the costa and hinder margin are faintly mottled with darker 

 grey, cilia grey. 



Posterior wings pale grey, darker towards the hind margin, with 

 the cilia fuscous. 



This is closely allied to G. sequax, Haworth ; but the head and 

 palpi are much darker, and the anterior wings are darker, greyer, 

 without the pale fasciae ; the first tuft also appears much larger, and 

 the apical marginal spots are less distinctly expressed. 



I reared two specimens of this species, from larvae collected by 

 Monsieur Milliere on Cistus sdlvifolius at Cannes in March 1866, 

 and which he forwarded to me at Mentone ; the perfect insects made 

 their appearance June 25th. Last summer Monsieur Milliere sent 

 me a specimen bred from Cistus albidus, in which the raised tufts,
