Orchestes Quercus. During a visit to the New Forest from the 

 8th to the 13th of June, I was struck with the brown appearance of the 

 oaks ; and on examination I found that nearly every leaf contained 

 between its cuticles a larva of an elongate, flattened form, which had 

 eaten the parenchyma of half the leaf, and by destroying its vitality 

 made it seem as if it had been scorched. About the concavity formed 

 by the separation of the upper and under skins of the leaf, the larvae 

 WTiggled with much activity when shaken or disturbed. In the majo- 

 rity of the leaves which I examined, the larvae had become pupa, and 

 in a few days pupge only were to be found. These retained all the ac- 

 tivity of the larvae when touched, but otherwise they remained at rest 

 in one part of the leaf, which just there had an inflated apj^earance. 

 I brought home with me several of the leaves, and on the 26th of June 

 the perfect insect emerged by making an aperture in the leaf. 



The leaves of the beech, I observed, had been attacked in a similar 

 way, and to as great an extent, but the depredator had escaped from 

 his cover. I beat a great number of Orchestes Fagi from the trees, 

 and have no doubt that they had done the deed. 



Thanasimus formicarius. I witnessed the carnivorous habits of this 

 insect in the New Forest. Having taken one from under the bark of 

 an oak, I j)ut it into a bottle, and immediately afterwards a Tomicus, 

 which was at once seized with the mandibles and held until nothing 

 but the horny shell remained. I have therefore no doubt that the 

 Thanasimus feeds on the wood-eating beetles and their larvae, which 

 were in great plenty where I found it.
