26 Notes on Insects Damaging Sugar Cane in Queensland. 



lines, the latter and a band below spiracles being usually paler and more 

 broken than centro-dorsal stripe. Dorsal area occupied by more or 

 less detached zig-zag markings and dots of same colour arranged roughly 

 to form four longitudinal bands. Ventral surface and prolegs wliitish 

 with a broken central stripe consisting of detached reddish-brown bh)tches 

 on four posterior abdominal segments between legs. Each body segment 

 supporting ten or more brown hairs arising from black tubercular dots, 

 more noticeable on terminal posterior segments and prolegs. Head and 

 first thoracic segment very pale yellow, the former with two brown 

 longitudinal V-shaped marks extending in four lines across whole of 

 dorsal surface. Labrum and base of mandibles white, the points of latter 

 dark brown, toothed. Body tapering towards tail end which terminates 

 in the extended points of anal prolegs. Length, 35 mm. 



(24) HARMOLOGA (MISERANA, Walk. ? ) (Family TORTRICIDAE). 

 Plate III., Fig. 24. p. 20. 



This species was found damaging young ra toons at Pyramid towards- 

 the end of October. 1914. 



The larva feeds openly, but constructs a hiding-place by affixing- 

 to the leaf-blade an oblong shaped piece of cane leaf in the form of a 

 slightly convex shield, under which it retreats when alarmed. 



Description of Cater pillar. 



Dorsal surface of first thoracic segment covered with a shining pale 

 yellow plate rounded behind ; seconci thoracic segment dark claret-red ; 

 third thoracic and abdominal segments whitish wath a smoky-brown 

 irregular centro-dorsal line, each segment having two large subdorsal 

 light claret-coloured blotches, two suffused more or less distinct pale- 

 brown transverse blotches between them on dorsal area, and four pearl- 

 like pustules, each supporting a single white hair. Anal segment with 

 a pearly-yellow dorsal plate carrying a number of long white hairs. 

 Ventral surface and claspers greenish-white, prolegs black. Head large, 

 light red. Body tapering slightly towards tail extremity. Length, 18 

 mm. A specimen kept in confinement pupated on 3rd December, the- 

 perfect insect emerging eight days later. 



Notes on the Imago. 

 The moth is obscurely coloured — silvery-gray on upi)er surface with 

 a few irregular small brown spots on the fore-wings, and hinder pair 

 suffused with delicate silvery-brown. Wing expanse, 17 nun. At pre- 

 sent it is of little or no economic importance.
