The sexes are closely similar. This species may be at once 

 distinguished from the preceding by the absence of discal dots. 



Townsville, Queensland, in September ; a series bred by Mr. 

 F. P. Dodd. The larvae bore the stems of species of Tristania. 



Thosea penthima, n. sp. 



Male, 28 mm. Head, palpi, thorax, and abdomen dull 

 brown. Antenjice whitish, pectinations ochreous-whitish, in 

 male pectinated to apex. Legs dull brown ; posterior 

 tibia3 with two pairs of spurs. Forewings triangular, 

 costa straight to near apex, apex obtusely rectangular, 

 termen strongly bowed, slightly oblique ; whitish-grey, suf- 

 fused with brownish, with a few scattered dark fuscous scales, 

 absence of brownish suffusion leaves a pale oblique fascia, its 

 anterior edge much suffused, its posterior edge sharply defined 

 by a. fuscous line from costa at five-sixths to dorsimi at two- 

 thirds ; a minute dark fuscous discal dot in fascia ; a pale 

 teiminal band from absence of brownish suffusion ; cilia 

 brownish -fuscous. Hindwings with termen rounded ; veins 

 6 and 7 stalked ; pale brownish ; cilia as forewings. 



Townsville, Queensland, in April ; one specimen received 

 from Mr. F. P. Dodd, who informs me that the larvae are oval 

 and very broad, covered with numerous tufts of stinging 

 spines, and feed on Carei/a ausfraJh'<. 



Elassoptila, n. g. 



Head with rounded anterior cone of scales. Palpi very 

 long, porrect, second joint five times breadth of eye, with 

 projecting scales at apex, terminal joint about one-fourth 

 second, obliquely ascending, stout, tolerably acute. Tongue 

 absent. AntenucB in male with long coarse double pectina- 

 tions continued almost to apex; in female filiform. Pos- 

 terior tibiae with two pairs of long Sjpurs. Forewings with 



2 from five-sixths, 4 froin angle, 5 from shortly above angle, 

 6 from near middle of cell, 7, 8, 9 stalked. Hindwings with 



3 and 4 connate, 5 parallel to 4, 6, and 7 long-stalked. 

 The peculiar palpi are sufficient to distinguish this genus. 



Elassoptila microxutha, n. sp. 

 Male, 14-16 mm. Head and thorax brown. Palpi brown, 

 apex and internal surface ochreous-whitish. Antennae dark 

 fuscous. Abdomen fuscous mixed, except at apex, with
