AT CANNES AND MENTONE IN 1866. 215 



A dull brown larva feeding in the dry heads of Lavandula stcechas, 

 which it attaches to the fresh shoots and burrows between them. 

 I have thus described it : 



Length 3-3 lines. Dull brown ; the head and second segment 

 shining dark brown ; the anal segment with a dark brown plate. 



I met with this at Cannes March llth, and at Mentone March 

 20th. When I left home for Switzerland, on the llth July, nothing 

 had emerged in the box containing these larvae ; when I returned 

 home on the 10th of August I found an obscure dead moth, par- 

 tially injured by the ravages of Psocus. I however relaxed it and 

 set it out, and rather suspect that it may be Mann's (EcopJwra 

 lavandulce (see ante, pp. 117 & 122). 



A yellowish larva mining the leaves of rosemary (Rosmarinus 

 officinalis); the mined leaves become yellowish brown and rather 

 inflated ; some excrement is protruded through a hole on the under- 

 side of the leaf, generally at the end of the mine nearest the foot- 

 stalk. 



The larva I have thus described : 



Length 2 lines ; yellowish, the incisions between the segments 

 rather paler; the head dark brown; the second segment with a 

 brown plate above ; the anal segment with a small pale grey plate ; 

 all the legs (16) pale yellowish. The larva is rather active. 



I met with these on the 27th March, the day before I left Men- 

 tone, on the rocks above Pont St. Louis, on the Italian side. 



I did not succeed in rearing anything from them. 



This seems also the proper place to mention two species of which 

 I received the larvae from Cannes and Mentone in November 1866. 



Gracilaria scalariella, Zeller (see ante, pp. 66 & 82). On the 

 14th of November I wrote to Monsieur Milliere asking for some of 

 the larvae of this species ; and on the 21st of that month he sent me 

 a box containing the blotched leaves of the Echium vulgare mined 

 by the larva of G. scalariella, with the remark that it was already 

 getting rather late for them. The perfect insects made their ap- 

 pearance during the month of December. 



Zelleria oleastrella, Milliere (his Tinea oleastrella, see ante, p. 191). 

 I was particularly anxious to get this insect, to ascertain to what 

 genus it should be referred ; and having asked Mr. J. T. Moggridge 

 (so well known to botanists by his work on the Flora of Mentone) 

 to search on the olive-trees in autumn for this and one or two other 

 species which were not obtainable in the spring months, I received 

 from him on the 23rd November and 6th December two of the 

 desired larvae, which formed slight webs amongst the olive-leaves, of 

 which they gnawed the underside. 



This larva I have thus described : 



Length 4| lines ; elongate, slender ; dark olive-green on the back, 

 whitish on the sides ; the dorsal vessel darker ; the spots white ; the 

 head pale brown, and the second segment pale brownish green.
