204 BARON WALCKENAER ON THE INSECTS 
seen in that country as a perfect insect upon the leaves of the vine 
towards the end of August. The larva rolls the leaf to hide itself, and 
attacks the young grape, but not the buds, being hatched too late. 
Schranck, in his Fauna Boica*, has placed these two insects in a par- 
ticular genus, to which he gives the name of Znvolvulus; but the Jnvol- 
vulus of the ancients, as we shall presently show, does not belong to 
the class Coleoptera, but to the Lepidoptera ; and I may remark that 
the genus Involvulus of Schranck, being badly constituted, has not been 
adopted by any naturalist. Though it contains but few species, some 
of them are distributed by M. Schcenherr among his Apoderi, one 
among his Aételabi, and a third among his Rhynchites. Aldrovandus 
was well acquainted with the Rhynchites Bacehus; and I am surprised 
that no naturalist has quoted this venerable father of natural history 
in modern Europe upon the subject of this small but formidable insect. 
He places it among the Cantharides, to which he devotes a chapter, 
thus separating them from the true Scarabei which occupy another 
chapter. The following is the description which he gives of this Cur- 
culio: “ Nonus numerus significat Convolvulum, Ira Greeis, Tagliadizzo 
vulgo apud Italos agricolas,corpore ceeruleo, pedibus obseure lutescentibus, 
in vite repertum, ac folia ejus depopulantem. Nascitur ex ovis bom- 
bicum ovis similibus magnitudine, colore rubicundis. Hie cum parere 
vult multa cumulat eonvolvitque folia (unde forte a Latinis id nominis 
datum), atque in his sua ova reponit.” Thus the name of Tagladizzo,— 
cutter,—given to it by the vine-dressers of Italy; its bluish colours; the 
injury done to the leaves of the vine, which the insect rolls up and in 
which it deposits its eggs, all mark with certainty the synonymy of our 
Rhynchites Betuleti or R. Bacchus with the ninth Cantharis of Aldro- 
vandust. But as to the identity of this insect with the Jps of the 
Greeks, and the Convolvulus of the Latin authors, which Aldrovandus 
attempts to establish, the continuation of our researches will prove that 
it must be rejected.

bouris de la Vigne-—After having treated of the Cantharides, Aldrovan- 
dus devotes an entire chapter to the [ps of the Greeks, to confirm his 
assertion in the preceding chapter that this insect is the Tagliadizzo of 
the cultivators of Italy ; but he remarks that he had only found this 
insect upon the vine, though the ancient authors say that it preys also 
upon horn. If Aldrovandus was wrong in maintaining that the Zps 
of the Greeks was the Convolvulus of the Latins, he was right in 
thinking that it belonged to the Coleoptera, and was one of those which 
the Italian agriculturists class among the Tagliadizzi, or cutters.
