The three insects mentioned are of interest to the West Indian readers of the Agricultural Nc-,t'S. The purple scale {Lcpidosaphes bcckii) is a pest of long standing of all citrus plants throughout the West Indies ; the spiny white fly (Akurocanfhus woglumi) has recently attracted attention by its attacks on citrus in Cuba, Jamaica, and the Bahamas (see Agricultural Ale7VS, Vol. XVI, pp 10 and 2821; the Hawaiian sugar-cane borer (RliaMociiemis obscurus) while abundant throughout the sugar-producing localities in the Pacific is not known to occur in the West Indies or in Central America, although Dr. W, D. Pierce in the 'Manuil of Dangerous Insects, likely to be introduced into the Unit'd States through importations', gives West Indian localities in the distiibu- tion of this pest. The inclusion of these loolities would •appear to be an error (see review in this Journal, Vol. XVII, p. 391). Formerly, the genus Sphenopliorus was made to in- clude the West Indian weevil borers of the sugar-cane, {Metamasius sericeus and J/. liemipteri/.s), the black weevil borer of the banana (Cosmopolites sordidus) and the Hawaiian sugar-cane borer (Rhahdocnemis obscurus), but the last mentioned species has always been considered to belong definitely to the Pacific regions, and not to the Caribbean or Atlantic localities. These insects are all .similar in habit. They generally attack dying or decaying plant tissue, although nbscurus i» said to be a serious p&
