THE YOUNG NATURALIST. 



On Sallows may be found the larvae of Cabera exanthemata (yellowish 

 green, with white spiracular line), Macaria alternata, M. notata, Lobophora 

 sexalista, Lomaspilis marginata (dark green with slender dorsal and sub- 

 dorsal lines and broad spiracular line), Scotosia undulata (grey with white 

 lines), Clostera reclusa (grey with yellow spots and a double yellow line along 

 the spiracles), (7. curtula (reddish grey when full grown with orange-yellow 

 warts on each side and black tubercles on the fifth and twelfth segments), 

 Pterottoma palpina, Pygera bucephala, Gelechia notalella (between united 

 leaves), Lithocolletis spinolella (in a blotch on the underside), L. salicicolella, 

 L. viminiella, and Nepticula salicisella. 



The curious Lobster caterpillar (Stauropus fagi) with such remarkably 

 long fore legs is occasionally found on beech trees, and still more rarely, on 

 birch and oak. Other beech-feeding larvse are Notodonta dictceoides, Demas 

 coryli, Drepana unguicula, Limacodes testudo, L. ascellus, Lithocolletis fagi- 

 nella and Nepticula iityrella. The last named makes rather broad galleries. 



The remarkable larvse of Limacodes testudo and asellus, of which mention 

 has just been made, are most commonly found on oak trees. They only 

 occur, I believe, in the south of England, and chiefly in the New Forest in 

 Hampshire. Their form is most peculiar, as they have no visible feet and 

 crawl like snails. Oak trees seem to be great favourites with caterpillars, as 

 quite a large number may be found feeding on their leaves. The list includes 

 the previously mentioned 8. fagi, D. coryli, P. dictcea and C, curtula, to- 

 gether with the rare Peridea trepida (yellowish green, with two white lines 

 along the back and an oblique and yellow stripe on the side of each segment ; 

 Diphthera orion (with silky hairs, reddish grey in colour, sometimes yellowish 

 grey, with a broad black stripe down the back, on which are large oval pale 

 yellow spots) ; the common Buff-tip and Pale Tussock caterpillars {Pygera 

 bucephala and Orgyia pudibunda) , Anchylopera Mitterbacheriana (dull green 

 in colour, with yellowish brown head and yellowish-looking secoud segment) ; 

 Gelechia triparella, the cone making Gracilaria Swederella, Ticheria dodon- 

 ceella and complanella. The last two mine the leaves and are both similar 

 in colour, i.e. yellowish ; dodonceella has a reddish brown head and makes 

 brown blotches, complanella has a pale head and makes white blotches. The 

 larva of Gelechia triparella is yellowish green, with a pale brown head and 

 black spots on its body. Ifc spins a silken web with which it fastens two oak 

 leaves flat upon each other, and gnaws their cuticle in a serpentine manner, 

 forming a crooked silken gallery. I believe it is pretty generally distributed 

 and fairly common in many places. 



Lithocolletis amyotella, roborella, hortella, Cramerella, Heegeriella, irradi- 

 ella, and quercifoliella all mine the underside of oak leaves; and other
