evening, the activity being greatest just about dusk. The fecundity 

 of the codhng moth in the Grand Valley is high. Three female moths 

 of the first brood deposited in confinement over 300 eggs each, the 

 highest total deposition by one moth being 316 eggs and 115 being the 

 largest number deposited in one day by a single female. An examina- 

 tion of a pear orchard devoid of fruit revealed the fact that the moth 

 larvae will sometimes burrow into the new growth, resulting in the 

 browning of the foliage. They prefer to spin up under dark-coloured 

 bands. 



The buff-coloured variety of the codling moth, known as Cydia 

 pomonella. L., var. simpsoni, Busck, was reared in the Grand Valley.

This index includes not only the scientific names of the insects 

 mentioned in volume i, but also the popular names, with a cross 

 reference to the technical name in each case. It is hoped that the 

 popular names used by the survey will be accepted by all working 

 entomologists and eventually be adopted by the American Association 

 of Economic Entomologists.

 Pummelo and its Culture. — Philippine Jl. Sci., Manila, xix,

The insects recorded as causing injury to the seedless Siamese 

 pomelo are : the ants, Pheidologeton sp., which attacks and kills the 

 roots just below the ground surface, and even the young twigs and 

 leaves, and which may be controlled by flooding and burning, and 

 Oecophylla smaragdina, F., which is common on the branches but 

 does no direct injury, though it fosters scale-insects; flea-beetles, 

 causing serious injury to the foliage ; and a moth, Phyllocnistis 

 citrella, Staint., which especially attacks young nursery trees and 

 also occurs on various species of Loranthus. 



Scale-insects occur in abundance on the stems, leaves and fruit. 

 They include Chrysomphalus aonidum, L., C. aurantii. Mask., Coccus 

 hesperidum, L., Lepidosaphes gloveri. Pack., Parlatoria brasiliensis, 

 P. ziziphus, Luc, Pseudaonidia trilohitiformis. Green, and Saissetia 

 sp. Termites do some damage by eating the roots, but do not cause 

 serious loss.

Araecerus fascictdatus, DeG., is recorded as attacking mace and 

 nutmegs in storage in Grenada during 1921. 



The remedial measures advocated include fumigation with carbon 

 bisulphide and the removal of spices from storage as soon as possible. 

 Whether fumigation and treatment with heat have any deleterious 

 effect on spices has not yet been ascertained.
