arose whether bees would be attracted to, and injured by them. To 

 settle this point, experiments were conducted in the autumn, when 

 frost had stopped the supply of honey. The poison mixture used 

 was composed of bran 20 lb., Paris green 1 lb., molasses | gal., 

 water about 2 gals., and 2 or 3 lemons. This was scattered about in 

 the apiary w^hen the bees w^ere flying freely, but only a few, 12 in 40 

 minutes, visited it, and these did not suffer from any ill effects. A 

 similar mixture, used especially against cutworms, and composed of 

 bran 2| lb., sugar 1 cup, water 1 qt. and half a lemon, was scattered 

 about the apiary, but was not visited by the bees at all.

The litchi [Litchi chinensis] is a tropical or subtropical fruit that is 

 just beginning to attract commercial attention outside of China, its 

 native country, where it has been cultivated for centuries. Most of 

 the insect pests attacking this plant are of minor importance, the 

 chief being the litchi fruit worm, the larva of a Tortricid moth, 

 Cryjytophlebia illepida, Butl., which at times causes considerable dam- 

 age to the fruit crop. A root-infesting mealy bug, apparently a species 

 of Pseudococais, often attacks the callus formed wdiere a layered branch 

 has been girdled to cause the formation of roots. These scales should 

 be destroyed by some contact poison after the soil has been removed, 

 or by a small amount of carbon bisulphide placed in the soil at some 

 distance from the callus. Saissetia heniisphaerica sometimes infests 

 weakly trees, but is easily controlled by oil emulsions. The Japanese 

 beetle, Adoretus tenuimacidatus, may attack very young trees, which 

 can be protected by spraying with arsenate of lead. The larvae of 

 the moth, Tortrix (Archips) postvittana, may cause injury to the foliage 

 and flowers, but can be controlled by spraying with arsenate of lead 

 paste containing 15 to 16 per cent, of arsenic oxide and used in the 

 proportion of 8 lb. to 100 U.S. gals, water. 



A mite, apparently an undescribed species of Erioph/jes, causes a 

 disease similar to the erinosis of grapes, but can be practically eradi- 

 cated by spraying with a solution of 10 oz. nicotine sul])hate and If lb. 

 whale-oil soap in 50 U.S. gals, water. The injury begins as small 

 galls or wart-like swellings on the upper surface of the leaf, there 

 being corresponding depressions on the under-surface with a browTi, 

 velvety appearance. 



Phjlloxera and American Vine Stocks. The Arguments for and against 

 the Establishment of a Nursery for P%/Zoa:;era-resistant Stocks in 

 South Australia. — Jl. Dept. Agric. S. Australia, Adelaide, xx, 

 no. 12, July 1917, pp. 963-969. [Received 16th October 1917.] 



A Conference of a branch of the S. Australian Agricultural Bureau 

 has discussed a motion for the protection of South Australian vine- 

 yards against a possible invasion of Phylloxera by the introduction 

 of sufficient resistant stock to establish a nursery adequate for the 

 reconstruction of the vineyards in the event of Phylloxera infestation. 

 It was pointed out that when Phylloxera was spreading rapidly through- 

 out Victoria sixteen years ago and Mildura was to be linked by rail
