The small black Agromyzid, the so-called " lantana seed Hy," has 

 been introduced into Fiji from Hawaii and is now so thoroughly 

 established that it is not possible to find Lantana camam within several 

 miles of Suva which does not display evidence of attack. Two boxes 

 of infested lantana berries were sent from Hawaii, one at ordinary 

 temperature and the other in cool storage to retard the development 

 of the feeding larvae. Few of the latter emerged, while several flies 

 were obtained from the former. A small Chalcid parasite of this 

 Agromyzid occurs in Fiji, but not in sufficient numbers to afTect its 

 spread seriously.

A fungus hitherto unrecorded, and as yet undescribed, has beeii! 

 found on Coccus viridis (green scale) infesting lime twigs from Mont- 

 serrat. It is nearly related to Emimsa fresenii, Nowak, and has also 

 been reported from Cuba. 



QuiNN ( — ). Black aphis of the peach. — Jl. Dept. Agric. S. Australia,

A remedy recommended for the black peach aphis [Aphis persicae- 

 niger] is a strong tobacco and soap wash, into each gallon of which one 

 pint of resin compound is mixed. The tobacco wash is made by 

 simmering tobacco waste (2 to 4 oz. per gallon) for a couple of hours in 

 hot water, or steeping it for a couple of days in cold water. The 

 liquor is then strained and 1 oz. of common soap is added per gallon. 

 Resin compound is made by boiling 1 lb. powdered resin, 1 lb. wasjiing 

 soda, and ^ lb. soap in each 5 gals, of water, until all are dissolved into 

 a strong brown liquid. This may be kept almost indefinitely, and 

 used as required. It may be made more concentrated for keeping and 

 diluted for use. If this wash can be applied fairly warm, its insecticidal 

 powers are increased.

In Canada, many species of Chloropids thrive both in wild grasses 

 and in cultivated cereals, the introduction of which, by providing an 

 abundance of food, ma}'^ be held to have transformed them into pests 

 of considerable magnitude, though their injury is usually overlooked 

 by the average farmer. Close inspection of spring wheat makes it 

 possible to determine the agent ; the larvae usually attack the central 

 shoot, cutting it oft' near its base, while the outer leaf nearly always 

 remains green. Though this much resembles the injury by the Hessian
