This genus may readily be distinguished from both 
Acidalia and Timandra by the well-defined angulation of 
the primaries. 
63. Calothysanis pulcherrima, n. 8. 
Wings above sap-green, crossed at about the basal 
fourth by a slightly curved white stripe broadly bordered 
with slaty grey ; a second white curved stripe edged with 
grey internally, and bounded externally by a broad grey 
discal band, which emits long dentate streaks along the 
nervures to the outer margin: primaries with the first 
two of these streaks (upon the last subcostal and 
third median branches) blackish ; costa silvery white ; 
secondaries with the first two discal dentate streaks 
abbreviated but blackish, the third well defined, blackish, 
and running to the angle of the wing at the extremity of 
the third median branch; all the wings with a slender 
black marginal line from the apex to the angle, and 
with white fringes; body white; under surface pearly 
white, with a grey indication of the discal band; 
expanse of wings, 11 lines. 
Prainha. 
Only one example of this very distinct and beautiful 
little species was obtained.

New to the collection of the British Museum ; it is 
probably the same as P. gambarina of Cramer (pl. 371, 8), 
of which moreover the irrufata of Guenée may be a 
variety ; from Felder’s figure (pl. exxvil. 18) it differs 
only in that the slaty grey coloration of the primaries 
terminates obliquely at the external angle (as it does in 
Cramev’s figure), and that there is no dusky band between 
the ordinary lines on the secondaries. 
* As amataria (Hiibner’s first species) has been referred to 
Timandra, I shall regard imitaria as the type of his genus,
