THE SUGAR-CANE MEALY-BUG. 43 
the destruction of these pests, makes it all the more important that there are so many 
valuable parasites preying upon them; and shows the value of introducing natural 
enemies to control a pest, for the four best parasites of these leaf-rollers are introduced 
species, viz., Macrodyctium omiodivorum, Chaleis obscurata, Frontina archippivora and 
Trichogramma pretiosa. - 
THE SUGAR-CANE MEALY-BUG. 
(Pseudococcus calceolarix Mask.) (Plate IV.) 
IDENTITY. 
This insect (see Pl. IV, from photographs by Mr. T. C. Barber) is 
identical with the sugar-cane mealy-bug common on cane in the 
southern parishes of Louisiana. The species is recorded by Mrs. 
Maria E. Fernald from Australia, Hawaii, Fiji, Jamaica, and Florida.? 
Koebele earlier records this mealy-bug on cane in Hawau..? 
RELATED SPECIES. 
The mealy-bug of the cane belongs to a very large family of insects, 
Coccidxe, which are world-wide in their distribution. Two other 
species of this family, Pseudococcus sacchary Ckll. and Aspidiotus 
cyanophylli Sign., have recently been recorded from Hawai by Mr. 
J. Kotinsky.¢ 
Three species, namely, Pseudococcus calceolariex, P. sacchari, and 
Aspidiotus sacchari Ckll., are known to attack sugar cane in the 
West Indies.¢ 
Van Deventer records several scale insects, among them Lecanium 
krugert Zehntn., Aspidiotus saccharicaulis Zehntn., Chionasprs spp., 
and a species of Pseudococcus very similar to P. calceolarix, on cane 
in Java. é 
In Mauritius two species of related insects, Jcerya seychellarum 
Westw. and Pulvinarna iceryi Guér., are reported as pests of sugar 
cane/ 
FOOD PLANTS. 
Mrs. Fernald gives the food plants of the sugar-cane mealy-bug 
as Calceolaria, Danthoma, Phormium tenaz, Cordyline australis, and
