species, P. purpurascens, from Ceylon, bores into the stem of Cinchona 

 succirubra. In dealing with these pests, various methods have been 

 used. The caterpillars may in some cases be reached with a wire 

 probe. Carbon bisulphide may be injected into the tunnel and the 

 latter closed. In the case of the Halmilla trees, kerosene was substituted 

 for carbon bisulphide and was reported to be successful.

Year ended March 31st 1914. — Agric. News, Barbados, xiv, no. 331,

Exo'phthalmus esuriens (the Leeward Islands root-borer) is credited 



with extensive damage to the maize crop, and considerable loss in the 



cane crop. It also seems hkely to give trouble on lime plantations.

for Orchards, with Combinations Recommended. — Ohio Agric. Expt. 



Sta., Wooster, Circular no. 149, 4th January 1915, pp. 53-60. 



This circular consists of instructions as to when to spray and what 



spray to use for apple, pear, plum and peach trees. Bordeaux mixture, 



4-4-50 formula, plus 3 lb. of lead arsenate to every 50 (U.S.) gallons ; 



" self-boiled " hme-sulphur and arsenate of lead, 3 lb. to every 50 (U.S.) 



gallons; arsenate of lead 3 lb. to 50 (U.S.) gallons and nicotine 



sulphate, 1 part to 700 parts of spray ; and ammoniacal copper 



carbonate are among the dressings recommended. By a " self-boiled " 



hme-sulphur is meant a mixture in which the whole of the heat 



required is obtained as a result of the chemical action of the lime on 



the sulphur. 



GiRAULT (A. A.). Notes on Trichogrammatidae (Hymen.). — Entom. 

 News. Philadelphia, xxvi, no. 1, January 1915, p. 32. 

 Trichogramma rninutum, Riley, is recorded as parasitic on Olene 

 pinicola, Dyar, in Massachusetts and Wisconsin. Oligosita sanguinea, 

 Gir., has been reared from cold storage material, mostly leaves and 

 stems of lucerne, accompanying cocoons of Hypera variabilis {Phyto- 

 nomus posticus) collected at Portici, Italy. It has probably been 

 introduced into Europe in connection with the importation of grasses. 



Laurent (P.). Army Worm Plague in Philadelphia {LeT?.)—E7itom. 

 News, Philadelphia, xxvi, no. 1, January 1915, p. 36. 

 Cirphis {Leucania) unipuncta (the army worm) is always more or 

 less common near Philadelphia and proved a veritable plague in 1914. 

 Contrar}^ to the generally accepted theory that the caterpillars destroy 

 the grass down to the ground, the author found that they often left 

 from a quarter to a half inch of the base of the blade standing. The 

 moth often becomes a plague when a wet season follows a dry one. The 

 young larvae of the first brood were noticed about 0th July, and were 

 full grown about 1st August, and about a week later the adults began 

 to emerge. The second brood of adult larvae was noticed about 18th 

 September, but was not so numerous. Spraying with lead arsenate, 

 scattering dry, slaked hme, and the use of a mijcture of Paris green and 

 bran were the controls adopted.
