report. Particular attention was given to tlie life Iiistory of Pulvinaria gaster- 

 alpha, which attacks cane, and to its parasite {Aphycus sp.)- The pois sabre 

 or jack-bean borer, which attacks both the plant itself and the pods, is said to 

 have recently come to attention, it even causing the complete loss of a crop 

 of the jack bean (Canavalia ensifonnls) in the northern part of the island. 



Insect notes {Ann. Rpt. Agr. and Crown Lands Seychelles, 1913, pp. 13-11). — 

 Among the insect pests noted as of particular importance in Seychelles during 

 the year are the green scale (Lecanium viride) on coffee, citrus, and ixora in 

 spite of the fungus parasite Cephalosporiiun lecanii; the barnacle scale {Aspi- 

 diotus ficus) on coconut, frangipane {Plumeria acuminata), breadfruit {Arto- 

 carpus incisa), pseudo sago palm (Cycas officinalis), citrus, and roses; L. 

 hesperidum on frangipane trees and water hyacinth {Eichornia crassipes) ; and 

 L. tessellatiim on coconut, takamaka (Calophyllum inophylluni), cinnamon, and 

 water hyacinth, which was found during the year to be attacked by C. lecanii. 

 It is stated that scales are always attended by ants, the commonest of which 

 is Technomyrniex alhipes. A list is given of 12 coccids which ants attend and 

 of 7 which they do not attend in the same degree. The coconut beetle {Meli- 

 tomma insulare) is said to be kept under control better than formerly through 

 the destruction of fallen trees and by removing the larvae from standing trees.
