Malacca and Johore are now as numerous as they have ever been. 

 Most of them have, however, been located and preparations have been 

 made for a vi^'orous campaign in July and the following months, the 

 success of wliith will depend on the supply of labour.

Euprodis clirijsorrhoea, which was so prevalent in 1913-14 in Nova- 

 Scotia [see this Review, Ser. A, iii, p. 678], now appears to be undo- 

 control, and during the winter of 1915, only 14,755 nests were found 

 in the province.

The Chalcidoidea described in this paper, include : — Signiphora 

 diptero-phaga, sp. n., in a tunnel of Dialraea in sugar-cane from 

 Trinidad ; Coccophagns aleurodici, sp. n., from Aleurodiciis on Theo-

 a Syrphid pupa in Trinidad ; and Enlophns magnisnlcatin^, sp. n., 

 reared from Coleophora sp.. on cherry in New Jersey.

Hcliothrips fcnionili.'i. ]?eut.. is wi<lely distributed and is found 

 principally in greenhouses, in which it has been recordt^d in the British 

 Isles, Italy, Belgium, Austria, Finland, German East Africa, Sweden, 

 and Spain, and it is also common in the United States. It was 

 first recorded on sugar-beet out of doors at Washington, D.C., in 

 1904, then on sugar-beets in California in 1907, and in 1914 from Porto 

 Rico on sugar-cane [see this Rcrieiv, Ser. A, ii, p. 308 1. It has also been 

 found 0)1 a great variety of other plants. A full description of all the 

 stages of this pest is given. Spraying is recoumiended as the best 

 method of control. In greenhouses a strong spray of water is sufiicient, 

 as it drives the younger stages from the leaves to which they are unable 

 to return and therefore die. In the course of some experiments? a 

 solution of 4 oz. nicotine sulphate with 4 lb. fish-oil soap in 50 U.S. gals, 

 of water killed 60 per cent, of the adults and 40 per cent, of the nvmphs. 

 With 5 oz. nicotine sulphate in the same mixture, 90 per cent, of the 

 adults and 60 per cent, of the nymphs were killed, and vdth. 6 oz. 

 nicotine sulphate, all the adults and 95 jDer cent, of the nymphs were 

 destroyed. The globule of excretion round the nymph may render it 

 less susceptible to the spray. The sprays should be apphed to both 

 sides of the leaves on a dull or cloudy day when the adults are less 

 active. A bibliography of 18 books concludes the article.
