insects. He mentioned to me, amongst other matters on this 

 subject, that the leaves of the Scolopendrium vulgare, near 

 Falmouth, were very generally attacked by some subcutaneous 

 larvae, which he believed to be Dipterous. I wished him to 

 inquire more into it, and some time after received the specimen 

 I sent you, which was the only one he had succeeded in 

 raising. Edward Doubleday. 



33. Aphis Persicce. — M. Morren has presented a memoir on 

 this insect to the Academie Royale des Sciences of Brussels. 

 It was borne in a hurricane over many parts of Belgium, during 

 the autumn of 1834. The emigration appeared to commence 

 between Bruges and Gand, and from this place, as a centre, 

 extended to the north-east and south. A single individual is 

 able to produce 10,000 as early as the second generation. 

 The female has an ovary of eight ovi or fcetigerens sheaths, 

 according to the season. These sheaths have each three or four 

 apartments, where the young are gradually developed. When 

 in the egg state they are seen in the terminating apartments. 

 M. Morren believes that there is an individualization of orga- 

 nized matter in this and allied species. The saccharine matter 

 is the nourishment of the young ones in their earliest stage of 

 being, so that the insect may be called one of the Mammalia.
