316 BARON WALCKENAER ON THE 



and is very similar to Zygoma Statices, " the forester:" it 

 is found on the dock and sorrel in the neighbourhood of 

 Paris. u 



The Pyralis Fasciana*- of Fabricius, whose fore-wings are 

 of a dull ash colour, with a brown fascia, and dots of the 

 same colour, has been mentioned as also injurious to the vine, 

 or as corresponding with one of the beforementioned species. 



There is yet another insect possibly referrible to the Teigne 

 de la Vigne, or Teigne du Raisin, of our cultivators : it is Tinea 

 Ambiguella, Hubn.y 



In order to ascertain the correct synonymy of the various 

 species of Lepidoptera especially injurious to the vine, men- 

 tioned under various names in the writings of naturalists, 

 travellers, and agriculturists, I have had recourse to^ the 

 practised skill and judicious criticism of one of the first Lepi- 

 dopterists in Europe, M. Duponchel. 



From the results of our united and careful examination it 

 would appear, that with the exception of those Lepidoptera 

 occasionally met with on the vine, and also on other plants, 

 without producing much injurious effect, (and of these we shall 

 speak hereafter,) all the Lepidoptera -which can be considered 

 especially injurious to the vine are reduced to the following 

 four species, the caterpillars of each of these rolling themselves 

 up in the leaves ; and the ancient names Involvulus and Con- 

 volvulus, therefore, applying to them in common, we can hardly 

 suppose that the observations made by the ancients on this 

 subject were sufficiently exact to enable them to determine the 

 differences between insects, a knowledge whereof, notwith- 

 standing the great labour of late bestowed on them, has been 

 but recently attained by modern naturalists. 



The first of these species is the one which was observed by 

 Bosc, and named by him Pyralis Vitis. Fabricius has described 

 this insect from the specimen in Bosc's collection, under the
