constant diligence and hard work, but is well worth the trouble. The 

 number o£ species seen (that is verified) and taken amounted to 62. 



I should recommend those who contemplate collecting Lepidoptera 

 in Provence to procure a copy of Donzel's " Notice Entomologique 

 sur les Environs de Digne," Lyon, Dumvolan et Eonet, 1851.

ECONOMY OF LAVERNA VINOLENTELLA, H.-S. 

 BY CHAS. G. BA.EEETT, F.E.S. 



In the middle of June last I received from Mr. W. Drury a 

 number of shoots of apple, distorted by the presence of some internal 

 feeder. In sending them he remarked, " Generally blossoms on spurs 

 are the parts selected ; the flower shrivels, and the larva makes its way 

 down the flower stalk into the spur itself, where it mines through the 

 centre pith down to the main branch, in some cases for an inch or two 

 in length. The wood then swells and throws out excrescences." These 

 larvae when received were very nearly full-fed ; they had apparently 

 also mined under the bark of the spurs, devouring the alburnum, and 

 this appeared more especially to have caused the swelling, some of the 

 spurs being thus quite roughened and disfigured. 



The larva is rather sluggish, moderately stout, and very even in 

 thickness throughout, yet the segments rather deeply divided ; head 

 decidedly smaller, shining umbreous ; dorsal p)late similar, but paler 

 and divided in the middle ; anal plate, and a slender transverse bar 

 placed behind it, darker umbreous ; general colour dull yellowish- 

 white, with a faint pink tinge over the dorsal region ; legs dark um- 

 breous ; prolegs ten in number, of the colour of the body. 



When full-fed it leaves the mine to spin up in a corner of a dead 

 leaf or any suitable substance, but probably upon the ground, since it 

 appears to have but little hold upon the twig in which it had fed. 



The moths emerged in July, of the usual deep black, and with the 

 two buttons of raised scales on the fore-wings most conspicuous, 

 indeed, I know of no species in which the raised tufts are proportion- 

 ately so large. It must be plentiful in some districts, yet is not very 

 commonly captured, indeed, so casually, that it was long looked upon 

 as a melanic variety of L. atra, Haw., Hellerella, Dup. From obser- 

 vation of these reared specimens, I think that it, very soon after 

 emerging, flies to the tops of the trees and there remains, resting upon 

 the twigs.
