1502 ARBORETUM AND FRUTICETUM. . PART III. 
Mocca-stone moth (Smith 
and Abbott?s Insects, t. 
72.3; and our fig. 1299.) 
The caterpillars of this 
insect appear all collected 
together in a web spun 
among the leaves. The 
larva is of a bright yel- 
low, streaked with brown, 
and the imago of a pale 
brown. The insect is 
equally common in Eu- 
rope and in America, 
There are plants in the 
Twickenham —_ Botanic 
Garden, and the Hackney 
arboretum; and at Wo- 
burn, Henfield, and Flitwick.

(Willd. and Forbes.) A native of Dauphiné, where, according to Willdenow, 
it forms a shrub 5 ft. or 6 ft. high, with dark violet-coloured, shining branches; 
but, according to the experience of Mr. Forbes, in the Woburn salictum, 
it is a handsome upright-growing tree, attaining the height of 12 ft. or 
14 ft., with the preceding year’s branches of a greyish brown colour, and 
the young twigs dark brown above, paler beneath, polished, and some- 
what angular, or striated, and very brittle. Introduced in 1818. The 
male, as observed in the London Horticultural Society’s arboretum, in 
1835, is an elegant kind, noticeable early in spring for its plentiful blos- 
soms, and subsequently for its leaves, which are remarkably neat in their 
figure and serrature, and more or less peculiar as compared with those of 
kindred kinds. The dark colour of the shoots of the preceding year or 
years is also an ornamental feature. There are plants at Woburn Abbey, 
Henfield, and Flitwick House. 
App. i. Tridndre of which there are Plants in the Country not 
7 described. 
S. tenuifolia Lodd. Cat., ed. 1836, and S. tenuifolia G., in the collection at Hackney, appear to be 
the same, and near akin to S. lanceolatum ; but are very different from the S. tenuifdlia of Smith. 
App. ii. Tridndre described, but not yet introduced, or of doubt- 
ful Identity with Species in the Country.
