BY WHICH THE VINE IS INFESTED. 209 



to determine the synonymy of the various species of the Lepidoptera 

 more particularly injurious to the vine, which I have found mentioned in 

 the works of naturalists, travellers, and agriculturists, I have had recourse 

 to the skilful and practised eye, and the judicious criticism of M. Dupon- 

 chel, one of the most accomplished lepidopterists of Europe. 



From an attentive examination of this subject we conclude that, with 

 the exception of those which are occasionally found upon the vine, as 

 well as upon other plants, without producing much injury, and of which 

 we shall treat in the following sections, all the species of Lepidoptera 

 which may be considered as particularly detrimental to the vine are 

 reduced to the four following, all producing caterpillars Avhich envelop 

 themselves in leaves, and to which may equally be applied the ancient 

 names of Involvuhis and Convolvulus. In fact M^e cannot possibly sup- 

 pose that the ancients made observations sufficiently exact to distinguish 

 differences which the moderns themselves, notwithstanding the extended 

 inquiries lately made upon the subject, have great difficulty in proving. 



The first of these species is that which was observed by Bosc, and 

 which he names Pyralis Vitis ; Fabricius has described this insect under 

 the name of Pyralis Vitanu, from the specimen in Bosc's collection. 

 For reasons, unfortunately too decisive, which we shall presently al- 

 lege, we shall not preserve either of these names : we name it Pyralis 

 Danticana, from Bosc's second name Dantic, the name Bosc having 

 been employed by Fabricius in his description of another Pyralis which 

 he calls Pyralis JBoscana. The second species is the Procris ampelo- 

 phaga of Duponchel, Bayle, and Passerini, the Procris Vitis of Bois- 

 duval. The third species is the Tortrix Roserana of Frolich, the Co- 

 chylisRoserana of Duponchel and Treitschke, and the Tinea amhigitella 

 of Hiibner. The fourth is the Toi-trix Heperana of Treitschke and Du- 

 ponchel, the Pyralis fasciana of Fabricius. 



The caterpillar of the Cochylis Roserana, mentioned by Frolich as 

 causing great devastations in the vineyards near Stuttgard, has not been 

 described by him or any other entomologist that I am acquainted with. 

 There remains then the Pyralis Danticana*, the ampelophuga^ of 

 Bayle and Passerini, and the Fasciana, the destructive effects of which 

 upon the vine cannot be called in question. The caterpillars of the
