AT CANNES AND MENTONE IN 1867. 223 



day, I visited a rocky place to the west of Mentone (near the Gorbio 

 valley) ; the scene was enlivened by the presence of Papilio Machaon 

 and Podalirius, Colias edusa, and Thecla rubi ; and, flying in the hot 

 sunshine, I met with a single male specimen of a Butalis in good con- 

 dition, and which, as far as one can judge from a solitary capture, I 

 am disposed to refer to B. senescens. 



Butalis dorycniella, Milliere (see ante, pp. 187 & 212). I again met 

 with the larvae of this species at Mentone on the 20th and 23rd of 

 March, on Dorycnium hirtum, but again failed to breed the imago. 



Acrolepia solidaginis, Staudinger (see ante, p. 157). I bred five 

 specimens of this insect, April 12th to 22nd, from larvae collected at 

 Mentone on the 20th of March ; they were mining the leaves of 

 Conyza squarrosa, forming large brown blotches, in which the excre- 

 ment was irregularly scattered. 



The larva I have thus described : 



Length 4J lines ; pale green ; the dorsal vessel dark green ; head 

 yellowish brown, with the mouth and sides darker ; the second seg- 

 ment pale yellowish brown. 



At the time I found these larvae I scarcely expected they would 

 produce anything different from the ordinary granitella; but all 

 the specimens I bred agree exactly with an Andalusian specimen 

 I have from Dr. Staudinger ; the anterior wings are perceptibly 

 darker than in granitella, and, I fancy, also broader ; and the dark 

 spot on the inner margin between the two pale spots has a distinctly 

 oblique position ; in the ordinary granitella it has almost invariably 

 a perpendicular position. 



Future observations must establish whether solidaginis is really 

 a good species. 



Acrolepia vesperella, Zeller (see ante, pp. 64, 81, & 213). I collected 

 the larvae of this species at Cannes and Mentone, March 1st to 16th. 

 When at the He Ste. -Marguerite on the llth of March I saw two of 

 the perfect insects on the wing ; but the flora and fauna of that island 

 are often a fortnight earlier than those of the mainland. In one 

 locality at Mentone, which I had previously noticed as a successful 

 corner for finding these larvae, I collected with the aid of my niece 

 forty larvae in the afternoon of March 16th. 



The perfect insects appeared with me from April 6th to 29th. 



Perhaps I should here mention a larva which I met with on the 

 He Ste. -Marguerite, near Cannes, March 10th, onHelichrysum stcechas, 

 and which I did not succeed in rearing. I noticed in Dr. Staudinger's 

 collection last summer that he had a specimen of Acrolepia eglan- 

 teriella, Mann (see ante, p. 125), labelled " ex 1. Helichrysum ; " and 

 possibly the larvae I found may have been the young larvae of that 

 species. 



The following is my description of it : 



Length 2 lines ; yellowish green ; the dorsal vessel dull green ; 

 head rather pale brown, with the mouth and the sides darker ; the
