$ Fore-wing white, hind -wing lemon-yellow; a common hind- 

 marginal roio of nervidar Mack sjwts. Fore-ioing : base very narrowly- 

 clouded with black ; costa witli narrow but well-defined black margin 

 from base to a little before apex, where it widens considerably, forming 

 an apical blackish tip as in Agathina ; hind-marginal nervular spots 

 variable in size, more or less narrowed and pointed baseward, — the spot 

 at end of lower radial nervule joined to apical blackish, and the lowest 

 spot (at end of submedian nerviu-e) very small. Hind-icing : hind- 

 marginal spots varying in size, more rounded than those in fore-wing, 

 one more in number than the corresponding series in Agcdhina, — the 

 additional (seventh) spot being at the end of first subcostal nervule ; 

 the middle (third and fourth) spots of this row smaller than the rest ; 

 base narrowly blackish about origins of nervm-es. Uisder side. — 

 Rind-wing and apex of fore-wing citron-yellow tinged u-ith oehreous. 

 Fore-vjing : costal black almost obliterated by white scaling ; apical 

 black only represented by three small spots at extremities of nervules ; 

 other hind-marginal spots much smaller than on upper side, — that on 

 submedian nervure minute or wanting ; no black at base, but only a 

 slight tinge of ochrey-yellow. Hind-wivg : costa at base and as far as 

 middle edged with orange -yellow ; hind-margin also narrowly tinged 

 with the same colour; hind-marginal spots rather larger and better 

 defined than on upper side. 



$ Similar to $, hut hind-iving paler or deeijer creamy yellow-ochreous. 

 Fore-vjing : no black at base, but a very faint tinge of yellowish ; hind- 

 marginal spots considerably larger (especially that on submedian ner- 

 vure), sometimes almost contiguous as far as first median nervule. 

 Hind-iuing : spots rounder, and usually slightly larger ; no black at 

 base. Under side. — As in $, but all the yellow colouring deeper and 

 more oehreous, being of about the same tint as in $ Agathina. 



Thorax clothed on the breast with orange-yell 010 pubescence. 



This near ally of Agathina is easily known by its constantly yellow 

 hind-wings (lemon-yellow in the ^, ochre-yellow in the ^) and pure 

 white fore-wings in both sexes. The conspicuous orange-red flush at 

 the base of the fore-wings on the under side which characterises 

 Agathina is wanting in Trimenia ; and the latter constantly possesses 

 an additional spot (at the extremity of the first subcostal nervule) in the 

 hind-wing, and has the under side of the thorax clothed with orange- 

 yellow (instead of white) hair.
