JOURNAL OF PROCEEDINGS. XXXV 



upon the ears of standing corn, which led to a discussion, in 

 which it was suggested that the only advisable remedy against the 

 attacks of fresh broods of these insects, was to subject the land to 

 repeated ploughings after the crop had been got off, and the in- 

 sects gone into the earth to undergo their transformations, in 

 order to expose them to the rooks as well as to the action of the 

 atmosphere. Salt having been suggested as serviceable to be 

 strewn over the fields, Mr. Waterhouse objected that the salt- 

 marshes in the neighbourhood of the sea were productive of many 

 insects. 



Dr. Calvert also exhibited a cocoon apparently of one of the 

 Eggar moths, the interior of which was occupied by a great num- 

 ber of the minute cocoons of one of the Ichneumones adsciti, 

 closely arranged with great regularity ; and Mr. Westwood ex- 

 hibited various other nests of different insects, in which the co- 

 coons had been arranged in a similar manner in close connexion 

 together. 



A Memoir by W. W. Saunders, Esq., was read, containing de- 

 scriptions of some new exotic Dipterous insects. 



Mr. Ashton, in allusion to the Scolopendra exhibited by Mr. 

 Newport at the last meeting, made some observations with the 

 view of showing that the various instances on record of the repro- 

 duction of limbs by the annulose animals never took place ex- 

 cept at the period of moulting, and whilst the animals were con- 

 sequently in an imperfect state, and that the process was not 

 analogous to that which was going forward throughout the life of 

 the higher animals, whereby a partial reproduction took place ; 

 and Mr. Yarrell suggested that a material difference took place 

 in respect to the moulting of crabs, which occurred during the 

 entire period of their existence, and insects in which moulting 

 never occurred after their arrival at the perfect state.
