208 BARON WALCKENAER ON THE INSECTS 
nification. The description of the industry attributed by Plautus to the 
Involvulus, to the little beast, “ bestiola que in pampini folio intorta 
implicat se,” can be applied only to caterpillars or the larve of the Lepi- 
doptera. The caterpillar not only coils up the leaf of the plant in which 
it envelops itself, like the larva of the Eumolpus or Coupe-bourgeon, 
but it attaches itself to it, and by means of silken filaments which it 
draws from its own body, constructs for its metamorphosis a web of silk, 
in which it envelops itself, “ implicat se.” The caterpillars of a whole 
family of Lepidoptera envelop themselves in this manner in the leaves 
of plants. To discover the Jnvolvulus or Convolvulus of the ancients 
it is therefore only necessary to examine those insects of the numerous 
family of the Phalene Tortrices of which the caterpillar attacks the vine. 
According to the observations of Bosc, the cultivators of the South of 
France give the name of Vine-moth to one of the Lepidoptera which is 
seldom found in the environs of Paris. The caterpillar or larva of this 
moth attacks the grapes when they have attained half of their full growth, 
and it proceeds from one grape to another by means of a gallery which 
it constructs*. There is another species named Grape-moth}, which 
also devours this fruit, and commences its ravages at the same period 
as the former, but it seldom attacks more than one grape at a time ; 
this species committed great depredations in the vineyards in the vicinity 
of Constance a few years ago. A species similar to this, or to the pre- 
ceding one, and of which one or two insects are sufficient to destroy a 
whole vine, was observed in the Crimea by Pallast. This species appears 
to be the caterpillar of a Procris or Zigena (a genus separated from 
the genus Sphina’), and is said to be nearly allied to the Zigena Statices ; 
it is found upon the sorrel and dock in the environs of Paris§. The 
Pyralis fasciana\|, which has anterior wings of a dark cinder colour, 
with a brown line and points of the same colour, has also been men- 
tioned as infesting the vine, or as corresponding to one of the species 
just alluded to. There is also another species which may be ranked 
among the insects to which our cultivators have given the names of 
Vine-moth and Grape-moth, we mean Hiubner’s Tinea ambiguellaq. But
