BY WHICH THE VINE JS 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 which envelop 
themselves in leaves, and to which may equally be applied the ancient 
names of Jnvolvulus and Convolvulus. In fact we 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 Vitana, from the specimen in Bosce’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 Bose’s second name Dantic, the name Bosc having 
been employed by Fabricius in his description of another Pyralis which 
he calls Pyralis Boscana. The second species is the Procris ampelo- 
phaga of Duponchel, Bayle, and Passerini, the Procris Vitis of Bois- 
duval. The third species is the Torériz Roserana of Frolich, the Co- 
chylis Roserana of Duponchel and Treitschke, and the Tinea ambiquella 
of Hubner. The fourth is the Zortrix Heperana of Treitschke and Du- 
ponchel, the Pyralis fasciana of Fabricius. 
The caterpillar of the Cochylis Roserana, mentioned by Frélich 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 ampelophaga+ of 
Bayle and Passerini, and the Fasciana, the destructive effects of which 
upon the vine cannot be called in question. The caterpillars of the
