sufficiently developed to have emerged — from August onwards. Where 

 the attack is prevalent to any important degree, it would also be 

 desirable to split some stems longitudinally during late winter or early 

 spring to ascertain whether larval attack is present. We may need 

 more information on this head. 



Where beetles are seen numerously on leafage, beating down would 

 be a good remedial measure. In Canon Fowler's * British Coleoptera,' 

 vol. v. p. 329, he mentions that "the perfect insect appears to be 

 to a certain extent crepuscular, and that he has found the males and 

 females together in numbers in an Osier bed near Repton, Burton-on- 

 Trent, at half-past four or five on a summer's morning ; but they 

 appeared to be scarce in the middle of the day, or in the afternoon in 

 the same locality." It would therefore be well, as in the case of 

 beating down Chafers, to make sure at what time the beetles are to 

 be found, and then, if shaken on to tarred cloths, or into pails with 

 some mixture that they could not escape from arranged for them to 

 fall into, probably great numbers could be got rid of.
