Mocca-stooe moth (Smith 



and Abbot? S Insects, t. 

 72, ; and our fig, 1299.) 



The caterpillars o\' this 

 insect appear all collected 

 together in a web spun 

 anions 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, Ilenfield, and Flitwick.

 Synoni/vics. S. triandra 1'illars De/ph., 3. p. 76-2. ; S. rtmygdalina var. Koch Conrm., p. 19. 

 The Sexes. Both sexes are described by Willd. ; the male is figured in Sal. Wob., and is in the 



London Horticultural Society's arboretum. 

 Bngrammgs. Sal. Wob., No. 17. ; andyfc. 17. in p. 1606. 



Spec. Char., dye. Leaves elliptical, rounded at the base, pointed at the tip, 

 serrated, whitely glaucous beneath. Catkins appearing with the leaves. 

 Flowers triandrous. Ovary pedicellated, ovate, smooth. Stigmas sessile. 

 ( Willd. and Forbes.) A native of Dauphine, 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 

 lift., 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 

 1 835, 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 scrrature, and more or less peculiar as compared with those of 

 kindred kinds. The dark colour of the shoots of the preceding year or 

 yean is also an ornamental feature. There are plants at Woburn Abbey, 

 Ilenfield, and Flitwick House.
