Bee-keepers are urged not to use box-hives and to avoid the im- 

 portation of queens wherever possible, as preventive measures against 

 the possible introduction of European or American foul-brood. The 

 presence of the wax-moth {GalJeria mellonella, L.) in the Island is 

 ascribed to lack of sanitation in the majority of cases. 



Coccids include Palaecoccus rosae, R. & H., on shade trees, where it is 

 parasitised by a Chalcid, and on roses, which are also attacked by Chry- 

 sompJialusJicifs, Ashm. .and C. dicti/ospermi,Moi'g. Aidacuspispentagona, 

 Targ., occurred on papa w and heliotrope. Pulvinaria cupaniae, Ckll., 

 injured imported mulberries, which however recovered after pruning 

 and spraying with heavy oil emulsion. Asterolecaniimi jmstidans, 

 Ckll., from an akee tree injured cacao, cultivated fig and geraniums. 

 Ptdvinaria pyriformis, Ckll., infesting leaves of guava was attacked 

 after the autumn rains by the parasitic fungus, Cephalospormm 

 lecanii. Pseudaonidia tesserata, d'Emm., was abundant on Cromantee 

 wattle {Matayba apetala), on ranioon [Trophis mcemosa) and on rock 

 sweet-wood {Nectandra coriacea), which also harboured Aspidiotus 

 cydoniae, Comst. Orthesia insignis, Douglas (lantana bug) was found 

 on coleus and chrysanthemums. Hemickionaspis minor, Mask., and 

 Saissetia hemisphaerica, Targ., attacked Asparagus racemosus. 



Miscellaneous pests include : Pachyzanda phaeopteralis, Gn., which 

 in the case of severe outbreak denudes pastures and thus injures stock. 

 The butterflv, Agraulis [Dione) ranillae, L., was reared from cater- 

 pillars defoliating sweet-cup [Passijiora maliformis). The Noctuid, 

 XantJiopastis timais, Cram., destroys lilies, which should be dusted 

 with arsenicals or the larvae hand-picked. Oiketicus sp. (almond 

 bagworm) was found on Terminalia catappa, Cupressiis erectiviridis, 

 and roses, and when numerous is extremely destructive. The Amatid, 

 Eunomia ruhripunctata, was reared from caterpillars destroying the 

 leaves of shade-vines of Bignonia. Dysdercus andreae, L. (cotton- 

 stainer) occurred in enormous numbers at the maturing and bursting 

 of the cotton-wood bolls. Cosmopolites sordidns, Germ, (black banana 

 weevil) is being studied and controls discussed. A beneficial Elaterid 

 grub {Pyrop)horus sp.) was present in infested bulbs. A large flight 

 of May bugs, found to be an undetermined species of Lachnosterna, 

 occurred in late April and early May. Cyclocephala tetrica, Voet., and 

 Ligyrusfossor, Latr., were also abundant at the same time.
