sprinklings with cold water,* at least for plants in 

 hot-houses, which are often attacked by these insects ; 

 but this remedy is not a certain one, nor to be relied 

 on as permanent in its effects. In the case of fruit- 

 trees labouring under this disease, the leaves are 

 constantly falling, and carrying with them to the 

 ground numbers of the mites, which either ascend 

 the tree again, or, if it be late in the season, har- 

 bour under stones, &c. near its foot, till the ensuing 

 spring. 



CHELIFER GEOFFROYI. f 



I ONCE took four specimens of this insect from 

 one little fly, which was so fettered in its movements 

 by the grasping hold of so many aggressors at once, 

 as hardly to be able to crawl. The natural habitat 

 of these pseudo-scorpions appears to be under the 

 bark of trees, whence they probably spring out on 

 their unwary prey basking near. They are often 

 found on Tipulce. 



ENTOMOSTRACA. 



Cyclopsina castor. J THIS little crustacean is very 

 amusing to watch in its habits. It occurs in pools 

 of water in this neighbourhood not unfrequently. 



* See Kollar's Treatise on Insects injurious to Gardeners, 

 Foresters, and Farmers, by Loudon, (p. 182,) where there is some 

 notice of this insect.
