It is widely distributed in the United States and feeds on a variety of 

 plants. The larvae appear in spring and attack the young foliage as soon 

 as it opens. These larvse mature by the end of May, and a second brood 

 is produced. The eggs are laid on the lower leaves. It is not known how 

 the insect passes the winter but it appears probable that the larval 

 state persists through the winter. A description of the moth is given in 

 the Proc, Acad. Nat. Sci. Phila. 347 (1860), and of the larva, pupa 

 and egg masses here. The larva is generally light green but varies to a 

 reddish or brownish green and generally has a darker green stripe along 

 the back ; the head is dark brown or black with brown mottling. 



The eggs are often parasitized and this keeps the pest well in check 

 as a rule. 



Fumigation with hydrocyanic acid was found ineffective but spray- 

 ing with lead arsenate promised well, though hand picking would seem 

 .the most effective measure when roses are affected. — F. J. C. 



Legislation in the West Indies for the Control of Pests and 

 Diseases of Imported Plants. By H. A. Ballou (West Indian 



Bull. vol. xi., 3, 1910, p. 197.) — A summary of the laws passed for 

 the above purpose by the Governments of Jamaica, Trinidad, Wind- 

 ward and Leeward Islands. 



The provisions of these laws fall under four heads : 



(1) Total prohibition. 



(2) Destruction of badly-infested plants on arrival. 



(3) Treatment of plants to destroy pests or diseases known or sus- 

 pected. 



(4) Periodical inspection with power to destroy if necessary.

Leg-umes, Additional Notes on Native, in Nebraska and 



Kansas. By Joseph Allen Warren {U .S.A. Dep. Agr., Bur. PI. Ind., 

 Circ. 70; September 1910). — Being a continuation of the observations 

 made in previous years to confirm or modify conclusions. It would 

 appear that there are more nodules on the roots of annual than peren- 

 nial legumes. It is possible but not confirmed that the wild legumes 

 may be able to inoculate the soil for cultivated crops (such as clover 

 or alfalfa). Nodules were not discovered on the roots of non-leguminous 

 plants with the exception of the buffalo berry. The most important 

 plants in number and distribution belonged to the genus Psoralea.

Lime Cultivation, Notes on. By H. A. Ballou {West Indian 

 Bull. vol. xi. No. 1, p. 39, 1910). — The use of experiment plots in 

 'Monserrat has shown that fortnightly hoeing and clean cultivation pro- 

 iduce great vigour of growth, and heavy early bearing, but at the 

 -expense of severe attacks of scale insects, together with a liability to 

 Toot disease, and possibly a premature weakening of the constitution. 

 ' The principal scale insect pests of limes, are the purple, white, and 

 ,§reen scales, of which the first two are most injurious. Their natural
