During the period under review, 1st July to 30th September 1920, 

 there was a drought in most of the tea districts, and mites, scale- 

 insects and Aphids were prevalent, particularly^ on bushes in poor 

 condition. In a few localities outbreaks of Heterusia cingala (red 

 slug), nettle grubs [Natada nararia and others) and Psychids have 

 occurred in unusual numbers, and a few instances of attack by Zeiizera 

 coffeae (red borer) were reported. 



Rubber was attacked b}' Saissetia nigra (black scale), and in a few 

 instances by Batocera rubus (stem and root borer) and Comocritis 

 pieria (bark-eating caterpillar) . 



The more important miscellaneous pests were Dacus {Badrocera) 

 cucurhitae (melon fly) in cucurbits, Odoiporus longicollis (banana 

 borer), Hypsipyla robusta (toon borer), Terastia meticitlosalis (dadap 

 borer) and Taragama dorsalis (dadap caterpillar). 



Experiments against cutworms ( Agrotis) were not successful enough 

 to warrant the use of poison baits by small cultivators, owing to the 

 cost of the materials — Paris green, pollard and jaggery. A moth 

 trap with sweetened bait also caught few moths, none of which were 

 Agrotis spp. Collection of the caterpillars daily and the protection 

 of young plants by means of tins or bands are still the most practical 

 measures against cutworms for small vegetable growers.

Of the new species described the following were bred from 

 plants of economic importance : — Assam : Batrachedra sacrata, from 

 Shorea robusta (probably a refuse feeder) : Phyllorycter [Lithocolletis) 

 hapalotoxa, from the bark of apple {Pyriis malus) ; and Acrocercops 

 malicola, from larvae mining in bark of apple, causing the outer bark 

 to peel off. Bengal : Cydia [Laspcyresia] pycnochra, from pods 

 of Sesbania grandiflora ; Hypophrictis plana, from a case-bearing larva 

 on the trunk of Mangifera ; Oxylyclina euryzona, from Heritiera 

 fonies ; Hyladaida perniciosa, from H. fomes ; SynnympJia perfrenis, 

 from H. minor ; and Acrocercops zygonoma from larvae mining under 

 bark of cotton (Gossypium). Central India: Xyloscopa (gen. n.) 

 heterocrossa , from log of Buchanania lati folia. North India : Proma- 

 lactis sponsalis, from logs of Shorea robusta. Andamans : Opogona 

 choleropis, from logs of Terminalia bialata. Nigeria and Natal : Plemy- 

 ristis oenochares, from dry cacao pods. Fiji : Stagmatophora erebinthia, 

 from pods of cow-pea ( Vigna).

Pieris rapae (cabbage butterfly) proved very troublesome during 

 the season. P. protodice was recorded, but has not yet proved injurious 

 in Ontario.
