employed for destroying the pests, among the most successful being the 

 flooding of the meadows, rolling after the cutting of the clover, and, 

 finally, collecting with small bags or nets. 



In his second article, the eminent Mr. Villa stated the fact that, in the 

 appendix to the work of Gene ( De quibusdam insectis Sardinia, novis au. 

 mi/iime cognitis, Mem. R. Accad. Sc. Torino, Ser. I., Vol. jg, Ser. u, Vol. 

 I.), which had been prepared by Prof. Moretti, this species had been 

 mentioned as among those having damaged clover. In pointing out how 

 this insect had destroyed clover, Mr. Villa expressed the belief that an 

 earlier attack had occurred, between the years 1834-35, in which the 

 injuries done were similar in character to that of this species. The 

 Station of Agricultural Entomology at Florence received notice, in June, 

 1879, tnat ^is insect had, in the Commune of Ferrara Erbagnana, de- 

 stroyed a field of 5 ettari (about 1 1 x /i acres) in extent. (See Relazione 

 intorno ai lavori della Stazione Entomologica agraria di Firenze, by At 

 Targioni-Tozzetti, in Annali di Agricoltnra del Minister di Agricoltura 

 e Conwiercio, Roma, 1879.) 



In the neighbourhood of Florence, besides having been found in the 

 clover in spring, it was, nevertheless, observed in the winter among moss 

 at the base of trees, and, though hibernating, during warm, sunny days 

 would come forth and bask in the sun.
