Upon examining the plants in hothouses, tire aphides in the larva 

 state are now feeding ; bat, after a minute micTc^wpkal riew, I bare 

 noticed some anatomical differences which lead me to infer that this aphis 

 is jriblj not the rastator, although a species rerj nearly allied to it, 

 Under these cra-uiostances, I most defer passing a decided opinion uniil 

 I hare observed it in the final or winged state. 



It is really of but little consequence to the husbandman to know the 

 particular aphis which caoses injury to any particular pla^t. for ererj 

 aphis is equally destructive, and whererer there are abundance of apli-ies. 

 there does the death of the plant occur. From tLis Tierr of tLe question, 

 I now camion gardeners to watch the aphides wtd,;li attack tLe strawberry 

 plants, and destroy them, together with their eggs, as far as possible, 

 otherwise they must nc*t be surprised to find tLeir sTraw-jerry pl&r.ia 

 destroyed. or rendered unfruitful through their agency. 



Let erery farmer, gardener, and naturalist now record their observa- 

 tions upon aphides, that the : ^ : lie -.:- i.:rj 1^,7 "-.^ : _^:er.rr&:ed

 into a warm room, they resomed their activity, and again fed upon the 

 plants. 



In greenhouses tiie Testators are now feeding on various plants. 

 Several of my crocuses, on which they were allowed to feed ^zniistorbed, are 

 now completely killed, and numerous others are on the high road to destruc- 

 tion. It appears that crocuses, like the potato plants, softer most when the 

 leaf is required to deposit the solid matter for the bafi> of the next year. 

 In my peregrinations round London, I have observed a few vasta^ors up:<n 

 nearly all the plants exposed for sale, which doobtleaB, daring the next 

 month, wffl multiply at their ordinary rate of pr>>iuc7ion. and tiras form a
