of the fore wings, the central white spot more triangular, the yellow fascia less dilated, and more curved inwardly. 
The caterpillar is ochre-coloured, ringed with black and with oblique white lateral stripes. It feeds on the oak 
and other trees, and the moth appears in August. It is found abundantly in the south-west parts of 
England, but is rare near London, where it is replaced by the preceding insect. Dr. Dahlbom, the Swedish 
entomologist, has recently figured L. Quercus, which agrees with that given by Wood. Our figure 13, 
copied from Hiibner, must therefore represent a variety analogous to the variety of Roboris, delineated in our 
floure 9. 
Lastocamps Spartit of Hubner, given by Stephens and Curtis as a variety of L. Roboris, is considered by 
Boisduval as distinct, and is an inhabitant of the south of Europe. 
Lastocampa ? Dumerti of Schrank (Hiibner, Bombyx, pl. 37, fig. 164; Wood, Ind. Ent., t. 53, fig. 33, and 
our figure 14,) has the wings brownish, with a pale central spot, and a pale clay-coloured fascia running across 
the wings; the hind margin is also pale clay-coloured. The caterpillar is slightly hairy, with black spots 
arranged in a double series. It undergoes its metamorphosis in the ground without making a cocoon, and the 
chrysalis has the tip of the body bimucronate. It is given by Stewart as a native species, but there is no other 
authority for its indigenous origin.

Dendrolimus Pini is from the specimen in the British Museum, as wellas G. Ilicifolia, which latter is however a foreign specimen, and it is 
very doubtful whether any well-authenticated British specimen exist; G. Populifolia is from Hiibner’s figure. The female of G. Quercifolia is 
drawn from a beautiful specimen given me by Mr. Doubleday ; and the male closely resembles it, except in size, being smaller. 
The caterpillars of D. Pini and G. Populi, and G. Ilicifolia, and the cocoons of D. Pini and G. Quercifolia, are from Hiibner. The cater-

This group is distinguished by having the fore wings entire, and the hind ones slightly dentated along the 
outer margin; the antenne of the males are nearly straight and deeply bipectinated; the palpi distinct and 
rather short ; the apex of the abdomen is not tufted ; the fore wings bear a white stigma-like central spot, and 
are not acute at the apex. Most of these characters will separate it from Odonestis, as well as from Gastropacha, 
with which it has been recently united by Boisduval, evidently on account of the similarity of its transfor- 
mations.
