islands they are experienced only at long intervals, probably because 

 the pest is kept in check by its natural enemies. In these islands the 

 insect is known as the Guinea grass moth or Guinea grass worm, but 

 the caterpillars are very fond of Para grass, and occasionally attack 

 other grasses. The rice worm {Laphygma frugiperda), known as the 

 corn-ear Avorm in the West Indies, and the fall army worm in the 

 United States, did a small amount of damage to sugar-cane in 

 British Guiana.

Against the pea weevil, Bruchus sp., peas should be j^lanted so that 

 the ripening season coincides with what is normally a dry spell, thereby 

 reducing the time possible for weevil attack. The crop should be 

 gathered and cured as quickly as possible and the contained insects 

 killed. Since the immature stages cannot stand long exposures to 

 high temperatures, thinly spreading out the peas on a strongly sun- 

 baked surface, such as a corrugated iron sheet, will dispose of most of 

 the eggs, larvae and pupae. The heat method, being simple and safe, 

 is superseding fumigation in flour mills. AVhcn this method is 

 impracticable, fumigation with carbon bisulphide, followed by careful 

 storage to prevent re-infestation, will prove an effective control.

During the months of April and May the insectary handled 71,600 

 pupae of the melon fly [Dacus cucurbitae] from which 3,665 individuals 

 of Opius fletcheri were bred and distributed. The following fruit-fly 

 and horn-fly parasites were also distributed: — Tetrastichus, 5,000; 

 0. humilis, 285 ; Diacliasma fullawayi, 210 ; D. tryoni, 225 ; 

 Spalangia amieroni, 60 ; and Paranagrus, the corn leaf-hopper 

 parasite, 13,625.

Pests intercepted during the month of April included beetles in the 

 portions of trees to which orchids were attached, and a few ants found 

 in the packing. 



During May shipments of plants from Cahfornia were fumigated on 

 account of being infested with Aphids and ants ; two baskets of garlic 

 were found infested with the larvae of a Lepidopteron, probably 

 Ephestia elutella, and w^ere fumigated with carbon bisulphide before 

 delivery ; four cases of roses from San Francisco were fumigated for 

 rose aphis. A crate of turnips, which was infested with the turnip 

 maggot, was ordered to be dumped at sea. 



Four packages of beneficial insects were received for the Hawaiian 

 Sugar Planters' Association, all soil and packing being destroyed.
