Some Lepidopterous Pests New to Sugar Cane in Queensland. 9 
The caterpillars had evidently found the foilage of sugar-cane more 
palatable than their native food-plants, and were observed when 
attacking very young sets to consume the entire leaf-blade. 
While resting inactively on cane-stools the lava assumes a lineal 
position, lying stretched at full length against the midrib or edge of 
a leaf, usually selecting some dead brownish portion harmonising with 
its own general colouration. If touched it seeks to escape notice by 
falling to the ground, and, contorting the body to the shape of a letter 
S or U, lies rigid and motionless, exposing to view the black transverse 
edges of the fourth and fifth abdominal segments, which, together with 
the somewhat snake-like form assumed, may possibly serve in some way 
to frighten small insectivorous birds and lizards. 
Larva. 
General colour variable, ight pinkish grey or pale ochreous yellow, 
with two darker, broad, subdorsal bands running the whole length of 
body, and a narrower band of same shade just above spiracles extending 
from head to middle of tenth body segment. Each abdominal segment 
with four tiny black dots (seen with pocket lens) on subdorsal bands, 
larger towards and on anal segment, and partly encircled by a whitish 
eye-like blotch. A yellowish band occurs immediately below spiracles. 
Venter with central dark-brown or blackish stripe. Entire body closely 
marbled with numerous irregular fine lines consisting of chains of dots 
and short streaks. Hind marginal edge of fourth and fifth body segments 
velvety blue-black. Legs yellowish. Head inconspicuous, frontal half 
of eyes dark greenish brown, labrum yellowish, base and teeth of 
mandibles black. Body tapering gradually towards each extremity, and 
sprinkled with a few short black hairs. Length about 45 mm. (1? in.). 
Pupa. 
Pupa efflorescent, yellowish brown; eyes and dorsal surface reddish 
and much darker; mesonotum transversely wrinkled; extremity of anal 
segment bluntly convex, the dorsum of same furnished with tooth-like 
lamelle arranged in semicircle, becoming less pronounced on venter, and 
enclosing a few yellow, hooked bristles. Length 20 mm. (about #? in.). 
The pupa is generally concealed within a sort of tube made by the 
caterpillar webbing together opposite edges of a leaf-blade, the tips of 
the foliage being often selected for such purpose. 
Imago (Perfect Insect). 
Greyish brown; fore-wing with a much darker streak running from 
apex to hind margin, bordered internally with light yellow, outwardly 
with reddish brown and a submarginal row of black specks. Hind-wing 
with a suffused central band and broad outer border dark grey; tibize 
and tarsi of male clothed with long dense hairs. Average wing expanse 
45 mm. (12 in.).
