egg-parasite. Lima beans were attacked by several important pests 

 which have already been noticed [see this Review, Ser. A, iv, p. 42]. 



It is to be regretted that a parasite of the predaceous wasp, Polistes 

 annularis, has made its appearance.

Sugar-cane was remarkably free from insect attacks during the 

 year, owing to favourable weather conditions, the only serious damage 

 being that of grasshoppers, which were however efficiently controlled 

 by poisoned bran mixture, composed of 25 lb. bran, 1 lb. Paris green, 

 2 quarts molasses, and the juice and skin of 4 sour oranges, which 

 proved more effective than Griddle mixture. Cotton was damaged 

 by cockroaches and field-crickets, and cotton-stainers, though not 

 very prevalent, were responsible for the first appearance in the island 

 of the internal boll rot of cotton, introduced by the insect when 

 puncturing the young boll.

During the year considerable damage has been caused to sugar-cane 

 by the larvae of the brown hard-back beetle {Lachnosterna sp.), but 

 its parasite, the Scoliid wasp {Tiphia paraUela) has been found for 

 the first time in Antigua, where it now appears to be established. 

 Their numbers may probably be increased by an improved supply 

 of food-plants, such as maize, sorghum and okra, which are attacked 

 by Aphids jDroducing quantities of honey-dew, by which the Tiphia 

 adults are attracted. The lightening of the soil by frequent tillage, 

 and the addition of coarse organic manures or lime, would render 

 more easy the entrance of the adult female Tiphia in search of grubs. 

 Cotton plants were severely attacked by Alabama argillacea (cotton 

 caterpillar), and to a less extent by Dysdercus sp. (cotton-stainer), 

 Heliothis obsoleta (boll- worm), Hemichionaspis miiior (white scale), and 

 Saissetia nigra (black scale). Limes were again attacked by the 

 weevil, Exophthahnus esuriens, which appeared during May and June, 

 though not in such large numbers as last year, owing to the energetic 

 control measures undertaken. The onion crop was attacked by 

 Prodenia sp. (onion caterpillar), which was however quite efficaciously 

 controlled by hand-picking, and also by Thrips tabaci and Lachnosterna 

 grubs.

A conference took place in March 1917 in Stavropol to discuss the 

 permanent organisation of campaigns against locusts in Northern 

 Caucasia. It was agreed that the success of the work demands the 

 creation of a special '' Anti-locust Bureau " in whose hands the whole
