Carpenter and Andrews state that the influence of the variety of 

 tea on the incidence of this Capsid is so slight as to be negligible 

 [R.A.E., A, vii, 534], but in Southern India this is not so, as China 

 and China hybrids are far more susceptible to attack than other 

 varieties.

At the Ohve Growers' Congress at Nice, M. Poutiers stated that of 

 the various parasites of Dacus oleae, Opius concolor, a Tunisian 

 species introduced into the south of France, appears to be the most 

 promising. 



In Tunisia it has no other host than D. oleae, except that when 

 the latter is lacking it parasitises a Trypetid infesting Zizyphus. 

 In Tunisia the harvested olives are stored until the crushing time, 

 a circumstance very favourable to 0. concolor. Other pests of the 

 olive in Tunisia include Phloeotribus scarabaeoides [oleae) and the olive 

 moth. Prays oleellus ; the latter is parasitised by a Chalcid, Ageniaspis 

 fiiscicollis.

The commonest timber-boring beetles in Britain are Lyctus linearis, 

 Goeze, L. brunneus, Steph., Anobium pimctatum, DeG., and Xestobium 

 rufovillosum, DeG. An account is given of the life-history and habits 

 of these species, and of the kinds of timber attacked. A less common 

 Anobiid is Ptilinus pectinicornis, L. 



The damage by these beetles can to a large extent be prevented. 

 A regular system of inspection and classification of stocks is outlined 

 as a preventive, and for timber stored in the open, treatment with
