legs dark-fuscous, middle and posterior pair ochreous-yellowish. 

 Abdomen ochreous-yellow, anal segments beneath blackish. 

 Fore wings elongate triangular ; costa gently arched, hindmargin 

 obliquely rounded, white ; markings blackish, inner margin 

 ochreous-yellow throughout, a thick elongate streak along costa 

 from very near base to beyoiid middle, posteriorly dilated ; a 

 straight slightly dentate line from basal extremity of this streak 

 to inner margin, but not ({uite reaching it ; a similar, but thicker 

 line from two-thirds of costal streak to inner margin before middle, 

 strongly curved outwards in middle ; a third similar line from 

 about four-fifths of costa to inner margin at four-tifths, strongly 

 curved outwards in the middle ; a well-defined black discal dot 

 midway between second and third lines ; costal edge above discal 

 dot ochreous-yellow ; a tolerably broad suffused hind marginal 

 band, from apex to anal angle, leaving an irregular rounded spot 

 of ground colour above middle of hindmargin ; cilia blackish, 

 with about six ochreous-white teeth at extremities of veins. 

 Hindwings ochreous-yellow, with a blackish apical patch, con- 

 tinued midway along hindmargin, strongly attenuated posteriorly. 

 Cilia ochreous-yellow, sufl'used with blackish at apex. 



Two specimens received from Mr. G. Lyell, jun., w'ho states 

 that it frequents Exocarpus cupressiformis ("Wild Cherry-tree") 

 in February and March, at Gisborne, Victoria. A distinct and 

 neat species, not closely allied to any other, but approaching 

 T. nivosa, Walk., by the wdiite fore wings, but immediately separ- 

 able by the yellow hindwings. At first sight it is not unlike a 

 large Comarchis or Thallarclia.
