Canadian Forestry Jl., Woodstock, Ont., xiv, no. 10, November 



1918, pp. 1928-1929, 1 fig. [Received 22nd September 1919,] 



Attention is drawn to the appearance in large numbers of the 

 bronze beetle, Agrilus anxius, on white birch in the forests of Quebec, 

 The bulk of the information given has been noticed elsewhere [see 

 this Review, Ser, A, vi, p. 62],

 Dominion. — N.Z. Jl. Sci. & Technol., Wellington, ii, no, 4-5, July

Comparison is made between the numbers of indigenous and exotic 

 insect pests in New Zealand. Of the noxious fauna the indigenous 

 species only amount to 18 per cent., but unless precautionary measures 

 are taken, this number is likely to increase owing to the insects 

 changing their food-plant when their natural one has been destroyed. 

 Very little is yet known of the destructive insects of New Zealand 

 and special work is being undertaken to increase this knowledge 

 with a view to pubUshing a comprehensive work dealing with the 

 matter. General co-operation of the farming community is essential 

 in order to carry out the undertaking successfully.

 Appearance of Insects makes planting of New Trees dangerous. — 



Mthly. Bull. Ohio Agric. Expt. Sta., Wooster, iv, no. 4, April 

 1919, pp. 124-128, 1 map. 



A list is given of the counties in which the 1919 brood of the 

 seventeen-year locusts [Tibicen septemdecim] are expected to be 

 most prevalent in Ohio. A brief account is given of the life-history 

 and habits [see this Revieiv, Ser. A, v, p. 403] and the usual remedial 

 measures are advocated [loc. cit., pp. 328 and 369].
