AT CANNES AND MENTONE IN 1867. 221 



number of the galls formed by the larvae of this species, and bred 

 the perfect insects from May 19th to June 9th. When at Cannes I 

 looked about for the Gypsophila saxifraga, wishing to introduce 

 Monsieur Milliere to this interesting larva ; but I did not see any of 

 the plant there : since then I have noticed the plant on the Lido, 

 near Venice, and near Eatisbon. 



Gelechia provinciella, n. sp., closely allied to G. marmorea, but 

 larger, anterior wings broader, and the markings duller ; the costal 

 hinder spot is anterior to the dorsal spot, and tends to form with it 

 an angulated fascia ; in G. marmorea " the costal spot is rather 

 posterior to the dorsal spot." (See Nat. Hist. Tineina, vol. x. 

 pp. 148, 149.) 



Of this I bred a nice series from larvae and sand-cocoons collected 

 at the roots of Silene nicceensis in a sandy wood near the coast, east 

 of Cannes, on the 28th of February. The Silene was in many places 

 eaten nearly level with the sand, the young shoots having evidently 

 been found highly palatable by some larvae. By searching amongst 

 the loose sand at the roots of these plants Monsieur Milliere and I 

 soon collected a considerable number of the larvae, which rather re- 

 minded me of the larva of G. marmorea ; and as we also found 

 sand- cocoons constructed similarly to the cocoons of that species, I 

 did not feel confident that the insect would prove distinct from G. 

 marmorea ; the characters, however, above given, especially the form 

 and position of the costal hinder spot, abundantly distinguish it. 



It was whilst collecting these larvae that we met with the larva of 

 Gelecliiafiyulella, Staudinger, already mentioned. 



The larva of Gelechia provinciella I have thus described : 



Length 4| lines ; greenish, with faint reddish-green dorsal and 

 subdorsal lines ; the subdorsal lines are scarcely quite continuous ; 

 head shining black ; the second segment with a large shining black 

 plate ; anal segment with a small black plate. 



This eats the leaves of Silene nicceensis, burying itself in the sand, 

 where it forms sand tubes like G. marmorea, and forms sand cocoons 

 in which to change to the pupa- state. 



The perfect insects appeared from April 6th to May 5th; they 

 may be briefly described thus : 



Exp. al. 6 lin. (My smallest specimen is about 5| lines, but all 

 the others are very equal in size.) Anterior wings greyish brown, 

 with the inner margin paler, and with three conspicuous black 

 marks : first, a small black spot above the fold, near the base ; 

 secondly, a blotch on the disk before the middle; and, thirdly, a 

 blotch on the disk beyond the middle ; the space between these two 

 is generally the palest portion of the wing, though in it we often 

 see some dark scales along the fold ; of the hinder opposite spots the 

 dorsal spot is the palest and most conspicuous, the costal spot is more 

 suffused, and, as above mentioned, is anterior to the dorsal spot, with 

 which it shows a tendency to form an angulated fascia. 



Gelechia cisti, Stainton (see ante, p. 211). I collected several of 

 the young larvae of this species at Cannes on the 5th and 6th of
