Primaries black ; venation and costa broadly grey, the 

 latter marked with five black spots, and the former, together 

 with seven interrupted yellow lines, breaking up the ground-

 basal third grey from costa to anal angle and the outer two 

 thirds yellow ; the latter has a central black spot, an outer 

 series of six large grey spots (the first and sixth of which are 

 double), and a marginal series of seven or eight small spots 

 of the same colour. Fringes of primaries blackish and of 

 secondaries yellow to the anal third, where they are blackish. 

 Under surface of primaries fuliginous grey, with black spots 

 of upperside reproduced ; secondaries as above.

Hob. Western China. 



Arichanna undularia, sp. n. 



Male similar to A. flavomacularia, but smaller, and the 

 interrupted yellow transverse lines on primaries are less 

 clearly defined. On the secondaries there is a rather broad 

 transverse black band in addition to outer and marginal series 

 of spots ; the blackish basal third does not extend beyond' the 

 limit of waved band, but encroaches further along the costa 

 and encloses the discal spot. Fringes of all the wings 

 blackish. Under surface : primaries fuliginous grey, with a 

 black discal spot and a few yellowish dots beyond ; second- 

 aries marked as above, but the ground-colour is paler.
