IxXXvi JOURNAL OF PROCEEDINGS. 



Mr. Darwin also informed the writer that he had taken in that 

 island many species of small insects belonging to European and 

 English genera. 



" A Decade of new exotic Hymcnoptera" By W. E. Shuckard, 

 Esq. 



" A Selection of Entomological Notices." By C. Darwin, Esq. ; 

 addressed to Professor Henslow, and communicated by W. Christy, 

 jun., Esq. 



" On the Turnip) Flea, Haltica nemorum, with an account of its 

 preparatory states." By Mr. Henry Le Keux ; in a letter addressed 

 to W. Raddon, Esq. 



The President, in allusion to the ravages of the turnip flea, stated 

 that he had understood that spreading manure in winter was con- 

 sidered much preferable to laying it immediately before sowing the 

 turnip-seed, the fly in the latter case being much more numerous than 

 when the former plan was adopted. 



M. Hoffmann stated that in German}'- he had practised the smearing 

 of broken pieces of glazed earthenware with birdlime, and spread 

 them about the fields, when the insects, being attracted by the shin- 

 ing appearance of these bits of earthenware, jumped upon them and 

 were captured. 



The President stated, in reference to the notices of irregular 

 coupling, mentioned at a former meeting, that he had been recently 

 informed of a similar occurrence having been observed between Blaps 

 fatidka and Akis reflexa. 



He also stated, in respect to the ravages of the Sirex juvenciis, that 

 in his father's grounds at Netley, he had observed that this insect 

 attacks those trees which have passed their prime, and that the Wey- 

 mouth pines are more subject to their attacks than the Scotch firs. 



He lUvCwise mentioned, with reference to the observations upon 

 the larva of Blaps mortisaga, that he was present when a medical 

 gentleman communicated to Mr. Curtis the larva of a Dy/Zcws voided 

 by a groviTi female who had long been subject to convulsions, and 

 that upon that occasion he had proposed castor oil as a remedy, 



Mr. Sells approved of this remedy, and added, that as turpentine 

 was used as a specific against Tcenia, it might also be serviceably 

 employed in cases similar to those mentioned by Mr. Hope.
