of all cotton seed from the Islands of Montserrat, St. Kitts, Nevis and 

 Anguilla. A proclamation by the Go\-ernor of Trinidad, dated 20th 

 November 1920, prohibits the importation into the Colony of cotton 

 seed, seed cotton, and ginned cotton, except under a permit issued 

 by the Director of Agriculture. Regulations were passed during 

 November "and December 1920, prohibiting the importation into 

 St. Vincent, St. Kitts, Nevis and Anguilla of cotton seed, lint cotton, 

 seed cotton, and of any packages, coverings, .bags, or other articles 

 used in connection with such material, without permission of the 

 authorities. 



A Note on the Mosaic Disease of Sugar-cane. — Agric. News. Barbados, 

 xix, no. 484, 13th November 1920, p. 366. 



Mosaic disease of sugar-cane is spreading rapidly throughout the 

 West Indies, and a similar disease has recently been discovered in 

 maize. To test the manner of dissemination, twelve individuals of 

 Aphis maidis were removed b}^ a camel's hair brush from diseased 

 sorghum plants, and placed upon maize seedlings in insect-proof 

 cages. The same number were similarly transferred from healthy 

 sorghum to other maize seedlings in a similar cage. In less than one 

 month eight of the twelve seedUngs in the first cage showed evidence 

 of mosaic disease, while those in the control cage remained perfectly 

 healthy. It is clear, therefore, that the disease can be dispersed to 

 an almost unlimited extent by this Aphid ; and there is, further, 

 no reason to suppose that transmission in nature is limited to it. The 

 possibility of eliminating the disease is discussed, but it is thought 

 that legislation and quarantine laws must be passed before this can be 

 accomplished.

 Ont., lii, no. 11, November 1920, pp. 257-258, 2 figs. 



Cydia [Laspeyresia) novimundi, sp. n., is described from garden 

 and field peas in Wisconsin. This species was formerly identified as 

 the European pea moth, C. (L.) nigricana [R.A.E, A, viii, 532], 

 but is readily separable by the characters of the male genitalia, which 

 are described and figured. If L. novirmmdi is not a native species 

 that has passed to the pea from some wild legume, it has probabl}^ 

 been introduced from the Orient ; in any case, it has been incorrectly 

 recorded as C. nigricana.
