Notes on Insects Damaging Sugar Cane in Queensland. 25 



(22) PADRAONA MARNAS, Feld. (Family HESPERIDAE). 



Plate III., Fig. 22, p. 20. 



Larva^. of this butterfly were collected on sugar-cane at Babinda 

 towards the end of November, 1914, inflicting damage identical in 

 character with that caused by the foregoing hesperids. 



Description of Larva. 

 Dull pale greenish-yellow, with obscure gray dorsal pulsating line. 

 First thoracic segment with a dark-brown transverse line above spiracles 

 interrupted on centre of back. Dorsal surface of anal segment forming 

 a dull yellow roughened plate, having a very conspicuous black elongate 

 blotch on each side and edged with yellow hairs. Ventral surface 

 pinkish. Head yellowish-brown covered with pustules; eyes contiguous 

 nearly to centre of face, margined behind and in front of face with 

 dark red; mandibles dark-red, edged with black. Length, 31 mm. (about 

 11/4 inches) ; width, -4 mm. 



A caterpillar kept in confinement pupated on the 19th December, 

 the butterfly emerging on the 28th of same month (nine days later). 



Description of Pupa. 



The pupa ditfers from those of the preceding species in the structure 

 of its anal segment, the extremity of which is cleft vertically and pro- 

 duced dorsally in the form of a plate-like ridge bearing four short stout 

 spurs. (See Fig. P, Plate III.) Both dorsal and ventral faces of this 

 plate are hollowed, the former very remarkably. Terminal abdominal 

 segments sui)porting numerous sliort bristly reddish hairs. Length, 

 22 mm. 



Kates on the Imago. 



General colouration of upper surface resembling that of T. augias- 

 Jxveffti, but differing in arrangement of markings as shown in Figs. 21 

 and 22, Plate III. Undersurface of hind-wings occupied in centre by a 

 large orange-yellow patch showing through from upper surface; rest 

 of Aving light brownish-yellow ; fore-wing dark-lirown, except on apical 

 and central portions. 



(23) CHUSARIS RHODIAS, Turner. (Family NOCTUIDAE). 



Plate III., Fig. 23, p. 20. 



The caterpillars were observed eating cane leaves in company with 

 Cirphis unipuncta near Gordonvale on 2nd September, 1914. 



Description of Caterpillar. 



General colour on upper surface light creamy-yellow, paler posteri- 

 orly, with irregular reddish-brown centro-dorsal and sub-dorsal
