A more. or less melanistic form : the orange area on apical 

 half of fore wing dull and brownish ; the white area of both 

 wings grajrish. On the imderside of the fore \ving the whole 

 of the cell and median area are deeply suffused with brown.

11. Colotis [Teracolus) etrida, Boisd, race limbata, 

 Butler, 6 



PL II., fig. 10.

This interesting aberration was captured, on the wing, by 

 Miss SheUa Black at Chilaw, in March, 1912. 



The fore wing is quite normal. On the hind wing, the

 Ormiston near Wellawaya in November, 1906. 



On the upper side of the fore wing there is a complete sup-

 discal spot on interspace 6 is enlarged and extended inwards 

 as far as the cell, and the greater part of the cell is occupied 

 by a large yellow patch. On the hind wing the usual spots
