of the fore wings, the central white spot more triangular, the yellow fascia less dilated, and more curved inwardly. 

 The caterpillar is oclire-colourcd, ringed with black and with oblique white lateral stripes. It feeds on the oak 

 and other trees, and the moth ai)pears in August. It is found abundantly in the south-west parts of 

 EnMand, 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 Rohoris, delineated in our 

 figure 9. 



Lasiocampa Si'AUTII of Iliibner, 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. 



Lasiocampa ? Du.meti of Schrank (Hiibner, Bombyx, jil. .']7, fig- 1<J-1 ; Wood, lud. 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 winfs ; the hind margin is also pale clay-coloured. The caterpillar is slightly hairy, witli black spots 

 arranged in a double series. It undergoes its metamorjdiosis 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 Britisli Museum, as well as G. Ilicifolia, which latter is however a foreign eperiincn, and it is 

 very doubtful whether any well-anthcnticated British specimen exist ; G. Populifolia is from HUbncr's figure. The female of G. Quercifulia is 

 drawn from a beautiful specimen given me by Jlr. Doublcday ; and the male closely resembles it, except in size, being smaller. 



The caterpillars of D. Pini .md G. Populi,and G. Ilicifolia, and the cocoons of D. Pini and G. Quercifolia, are from Hubncr. The cater- 

 pillar of G. Quercifolia is from a finely-prcserved specimen in the British Museum, purchased with others at the sale of Mr. Donovan. H. N. II

This group is distinguished by having the fore wings entire, and the hind ones slightly dentated along the 

 outer margin ; the antennre of the males are nearly straight and deeply bipectinated ; the palpi distinct and 

 rather short ; the apex of the abdomen is not tuftud ; the fore wings bear a white stigma-like central spot, and 

 are not acute at the apex. Jlost 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.
