owing probably to the fact that the fruit was a month earlier and had 

 set before C. capitata had begun to oviposit. Mangoes and oranges 

 are seldom attacked by C. capitata, presumably because the fly has 

 finished its life-cycle when these fruits are ripe in March and April. 

 These observations show that the early peach varieties, like those of 

 the Cape, are more suitable than the later varieties for cultivation in 

 Madagascar.

 Species of British Tortricidae. — Entom. Mthly. Mag., London, li, 

 no. 608, January 1915, pp. 8-11. 

 Cnephasia genitalana, sp. n., from Folkestone, Poecilochrotna 



pomedaxana, sp. n., bred from larvae found feeding on old apple trees 



and once upon oak and reported to be confined to these trees, and 



Lipopfycha aeratana, sp. n., are described.

 Mthly. Mag., London, h, no. 608, January 1915, pp. 18-19. 

 A tin of chocolate powder is reported to have been found swarming 

 with Ptinus fedus, Boield., in all its stages. This beetle is also recorded 

 as breeding in and thriving on Cayenne pepper, stored in a chemist's 

 shop at Nottingham. 



Day (F. H.). Late Larvae of Pier is hrassicae. — Entom. Mthly. Mag., 

 London, U, no. 608, January 1915, p. 19. 



Pieris hrassicae larvae are stated to have been feeding very late in 

 1914 in a garden at Carlisle ; examples collected from Brussels sprouts 

 on 28th November pupated 8th December. These were quite free 

 from Ichneumonid parasites, whereas some years ago 95 per cent, 

 of these larvae, which the waiter was attempting to rear, were infested 

 with Apanteles glomeratus. It is suggested that this immunity from 

 attack is due to the parasites' activity for the season having ended 

 with the previous brood.

 9th January 1915, p. 15. 



An attack of the currant root louse, identified by Theobald as a 

 migrant form of Schizoneura ulmi, is recorded. This pest, which may 

 easily be overlooked, even when prevalent, is fomid on the roots of 

 young currant bushes. Infested roots should be dipped in a strong 

 solution of soft soap. 



HiLEY (W. E.). On the mode of infection of larch canker and the 



possible means of preventing it. — Qrtly. Jl. Forestry, London, ix, 



no. 1, January 1915, pp. 7-17, 6 figs. 



The infection of larch canker, Dasyscypha (Peziza) calycina, may 



be furthered by wounds of various kinds, and according to Massee, 



infection will follow if spores are placed on the excretion found in 



spring around the pmictures of Chermes abietis, which bores through 



the cork into the living tissues beneath. Speyer concludes that the 



holes are too small to allow of the entrv of the fmigus germ tubes and 



there is little evidence that Chermes really encourages canker.
