members of the genus PJii/Uuhius. P. urlicne being the predominant 

 species with a few P. ohlonyus in addition. About the same date the 

 owner of the plantation wrote to say that lie also had been breeding out 

 adult winged weevils but in his case all appeared to be P. ohlongus. 

 Unfortunately no examination of the plantation was made until June 6th, 

 when P. ohlongus was still present in large numbers but P. urticae 

 appeared to have gone, none being found even in the adjacent hedge- 

 rows. The plantation had been sprayed very heavily with lead arsenate 

 and it was said that vast numbers of P. ohlongus had been killed. 



At this time curiously enough there were still a few larvae indis- 

 tinguishable from those of Phyllobius at the roots of the strawberries, 

 but none have been reared and their identity is therefore unknown. 



Larvae of the genus Phyllohius do not in the past seem to have been 

 regarded as of much economic importance either in Britain or on the 

 continent. Reh (in Sorauer's Handbuch der Pjlanzekrankheifen, iii, p. 544) 

 says that they are not harmful with the exception of those of P. glaucus, 

 Scop. {P. calcaratus, F.) which he records on the authority of Ritzema 

 Bos as having caused damage to the roots of strawberries. However, 

 this note is written without any extensive reference to the literature 

 on the genus and it is possible that there is more information available.
