302 Insect Pests. 



the Nut Weevils are killed at the same time. This I tried at home 

 with complete success. 



NATURAL ENEMIES. 



Wbitehead (1) refers to the good done by Tits, and describes the 

 Great and -Blue Tits hunting for the beetles. No definite obser- 

 vations have been made, and this statement must be taken with 

 caution.

THE NUT LEAF WEEVIL. 



(Stropliosomus cori/li. Fabr.) 



This insect is referred to by Ormerod (1), but I am not aware 

 that it does any harm to nuts in this country. No growers I have 

 consulted know anything of it, nor have I seen it on

 It is quite a widely distributed insect in this country, 

 according to Canon Fowler (5). It is also referred to 

 in Schlich's ' Manual of Forestry ' by Fisher (6).

appearing in the spring for the most part, in great num- 

 bers, and gnaws the leaves of hazels," etc. (p. 590) (3). 



Taschenberg (p. 103) says : " The beetle appears in many years in 

 great numbers, not only on hazels, as might be inferred from its 

 scientific name, but also on birch, oak, beech, Scotch fir and pine, 

 where from May till June they feed on the buds and leaves and the 

 bark of the young shoots, and in some localities have destroyed young 

 trees of the above mentioned kinds." 



Ormerod received them in great numbers from Great Brington, 

 Northampton, where they with other beetles were doing great damage 

 in 1889 to conifers. 



The beetle is quite small, barely i inch in length, black in colour, 

 with grey and brown scales, dull red legs and antennre ; the elytra
