ENTOMOLOGY. 

 Gbacilabia bufipennella. 

 The common Walnut tree is remarkable for its 

 freedom from the attacks of insects, the peculiar 

 flavour of the leaves being the probable cause of this 

 immunity; indeed, Loudon, in his "Arboretum 

 Britannicum,'' does not enumerate a single species of 

 insect attached to this tree, although the Black Walnut 

 of North America nourishes the caterpillars of a large 

 moth of the same genus as our great red under-wing 

 moth. A small beetle, however, Lyctus Juglandis, lives 

 under the decaying bark of the English species. 



It was therefore with considerable surprise that, in 



passing along the high road from Botzen to the 



Brenner Pass iu the Tyrol in the third week of last 



May, we observed that the greater part of the Walnut 



trees which are planted along the road sides had the 



appearance of having been scorched or affected by a 



very severe frost, a great proportion of the leaves 



having a large portion brown and withered. On 



examining them we found this was caused by their having 



been rolled up and gnawed to pieces by numbers of 



minute caterpillars, many of which were still within the 



rolls, although the greater part of the mischief had 



already been completed, and the caterpillars left their 



rolls. There was nothing peculiar in the manner in 



which the roll was formed, of which an idea will be 



obtained from the accomp inying figure. There had 



been considerable rain at the time, and a good deal of 



the excrement of the larvae combined to give the 



leaves a decayed state. 



The caterpillars are rather more than a quarter of an 

 inch long, fleshy, with a few very fine erect hairs on the 

 different segments of the body. They have a semi- 

 transparent skin, and are of a dull clay colour with a 

 dark brown streak down the body formed by the 

 visceral canal, the jaws are brown, and on the first 

 segment of the body is a darker-coloured horny patch 

 or scale. When ready to assume the chrysalis state 

 these caterpillars had become of a very pale green 

 colour, with the head and tail slightly clay-coloured. 

 In addition to the three ordinary pairs of legs attached 

 to the first three segments, and the single pair at the 

 extremity of the body, these caterpillars were only pro- 

 vided with three pairs of ventral feet. 



When full grown they leave the old roll of the 

 leaf, which they have greatly devoured and rendered 

 unsightly, and curl up a small portion of the margin of 

 the still uncousumed part of the leaf, forming it into a 

 kind of cradle, spun round with pale greenish white 

 silk, and within which they assume the pupa state, 

 which is remarkable for its very slender form as well as 

 for the great length of the pair of antennae-cases, which
