 A species of Pseudococcus, probably P. {Dactylopius) adonidum, L., 

 was one of the insects that became more numerous as a result of the 

 prolonged dry weather in 1913 and 1914. Another factor favourable 

 to the increase of this scale is the substitution of lamtoro {Leucaena 

 glauca) for dadap [Erythrina] as a shade-tree, the former being a. 

 favoured food-plant. The chief injury to coffee is that done to the 

 young berry-clusters ; the new tips of the twigs and the roots also 

 suffer. It has been found that a carefully applied contact-spray con- 

 taining 4 per cent, of petroleum is efficient against this scale.

 During 1917-18 a proclamation, dated 24th October 1917, was 

 issued to prevent the introduction of Pectinophora gossypiella (pink 

 bollworm) into the Island. The principal provision is as follows : 

 The importation into the Presidency of seed-cotton or cotton-seed 

 from all countries outside the colony of the Leeward Islands is pro- 

 hibited, save and except from some other Presidency of the Colony, or 

 from the Colony of Trinidad and Tobago and its Dependencies, or 

 from the Colonies of Grenada, St. Vincent, and St. Lucia, provided that 

 small quantities of cotton-seed for experimental purposes may be 

 imported into the Presidency on the written permission of the Curator 

 of the Botanic Station, on such terms and conditions as he may 

 prescribe.

The Northern District of Lower California, which is politically a part 



of Mexico, but economically a dependency of the United States, is as 



yet free from cotton pests, although cotton constitutes the principal 



source of the wealth of the district. In order to maintain this im m unity 



a Quarantine Order has been issued prohibiting the importation into 



the district of cotton seed except through the ports of Mexicali and 



Los Algodones. The text of the decree is given. Slight modifications 



through governmental orders make this decree include cotton as well 



as cotton seed.
