Dactijlopius {Cocms) co»fi(SKS indicus, Green, which was introduced 

 for the suppression of the prickly pear, Opimtia monocantha. The 

 work of this insect however is greatly impaired by a predatory 

 Coccinellid beetle, Cryplolaemus monirouzieri. 



The pests intercepted in quarantine during the year include : 

 Pedinopkom (Gelechia) gossijpiella (pink bollworm) on cotton from 

 Egypt ; a cotton stainer, Dysdercus sp., on cotton seed from Papua ; 

 Dkitraea sp. and Chionaspis sp. on sugar-cane from Java ; EpJiestia 

 sp. and Tenehroides mauritanica in dried fruit from Portugal ; Alplii- 

 tobius piceus in bags of rice from the East ; Bruchus ? ramiconiis 

 and Bruchus sp. in algaroba {Prosopis juliflora) from Argentina ; 

 Rhizoglyphus sp. in avocado (Persea) seeds from Fiji and in bulbs from 

 England ; Heiewbostrychus pileatus and Dinoderus sp. in wood of 

 tea chests from India ; and Asterolecanium sp. on the bark of a stake 

 received with plants from New Zealand.

The chief pests dealt with during the year under review in addition 

 to those recorded in the preceding paper include : Epilachna vigin- 

 tiocto punctata infesting potatoes ; Herse {CJiaerocampa) convolvuli on 

 sweet potato ; a Pyralid caterpillar, Endotricha puncticostalis, on 

 pea-nuts (Araehis). Cotton was infested by a Noctuid, Anomis crosa 

 {Cosmophila xanthindyma), Earias huegeli, Oxycarenus luctuosus, 

 Dysdercus sidae, and a defoliating beetle, ? Monolepta rosea.. 

 Cucurbitaceae were attacked by Aulacophora hilaris and Eptilachna 

 vigintioctopunctata, though the latter did not attack water-melons. 



Other pests included Phytometra chalcites and Agrotis ypsilon on 

 cabbages and turnips ; Isodon puncticolle on tomatoes ; the Oni-jcid, 

 Armadillidiam sp. on vegetables generally ; Cydia {Carpocapsa) 

 pomonella and Oecanthus sp., on apples ; Orgyia postica on plums ; 

 Nysius vinitor (false chinch bug), termites and a scale-insect on 

 peaches ; Bostrychns jesuita, an undetermined Cerambycid, Morganelki 

 {Hemiberlesea) longispina, a Jassid, Kybos sp., and a beetle, Galerucella 

 semipullata, on figs ; Chionaspis dilatata on mango ; Pseudococcus sp.. 

 Coccus {Lecanium) longulits and Saissetia {L.) nigra on custard 

 apples ; an undetermined white scale and S. (Lecanium) oleae on 

 persimmon ; Aspidiotus perniciosus on Joquat ; Monolepta rosea. 

 Coccus longulus and termites on grape-vine ; an undetermined root-

 Biprorulus bibax (green horn bug), termites, Chrysomphalus aurantii, 

 Aspidiotus hederae, Ceroplastes ceriferus, Chionaspis citri on Citrus ;

 Tortricid, Cryptophlebia illepida (" Arctiophora " ombrodetla) on 

 Queensland nut [Macadamia ternifolia) ; Psylla fici on fig {Ficus 

 macrophylla) ; Brithys crini and Calogramma festiva on Crinuni and 

 Aniaryllis ; and an unidentified Cerambycid on Acacia harpophylla. 



Pseudonionas camjjestris, a bacterial disease of cabbages and 

 turnips etc., is thought to be disseminated by biting insects. Many 

 diseases of Citrus plants are caused by mites ; thus russeting i>
