Erionota. 



Erionota, Mabille, Ann. Soc. Ent. Belg. xxi. p. 34 (1878) ; Watson, P. Z. S. 1893, p. 86. Type 

 thrax, Linn. 



Large species expanding 60 to 90 mm. Hind wing with vein 7 almost equidistant 

 between 6 and 8, veins 2 and 3 normal in both sexes. 

 We are acquainted with the three following species : — 



1 (4). Pale spots on fore wing above yellow. 



2 (3) . Fore wing above : pale spot in cell 3 remote from the others, situate 



near the middle of the cell, variable in shape, but never wider than 



high thrax, Linn. 



3 (2) . Fore wing above : pale spot in cell 3 occupying the basal half of the 



cell with the exception of the extreme base, and therefore only 



separated from that in cell 2 by vein 3 ........ . alexandra, Semper. 



4 (1). Pale spots on fore wing above pure white grandis, Leech.

Ha b. Sikkim (Moller) ; Khasias (Hamilton) ; Pulo Laut, Sambawa, Bali (Doherty) ; 

 Nias (Modigliani) ; Andamans (de Boepstorff) ; Philippines (Semper) ; Palawan (Platen). 



Two specimens of acroleuca, named by de Niceville, from the Andamans, seem to 

 us inseparable from thrax, though they are conspicuously smaller. 



Erionota Alexandra. 



Erionota alexandra, Semper, Schmett. Philipp. p. 312 (1892). 

 Hab. N.W. Luzon (Semper). 

 The larva of this species is very differently coloured to that of E. thrax

This genus may be distinguished from Erionota by having veins 2 and 3 of the
