154 MESSES. H. J. ELWES AND JAMES EDWARDS: 



with which we are acquainted. The species of the orbifer group are exceedingly 

 closely allied ; the male genitalia and the essential wing-pattern are practically 

 identical, but the characters given below will separate the majority of specimens- 

 Therapne, Rbr., put by Staudinger as a variety of sao, is just as distinct from the latter 

 as are orbifer and ali. 



1 (66). Hind wing below dark, with a pale median band. 



2 (57). Such band macular, generally much broken. 



3 (32). Pore wing with a subterminal series of. small pale spots. 



4 (5) . Fore wing below with a distinct white spot (not merely a pale 



dash) near the base of the cell. Median pale band on hind 



wing below continuous from veins 2-7 galba, Fab. 



5 (4). Fore wing below with the basal pale marking in the cell (when 



present) a dash, not a distinct spot. 



6 (21). Hind wing below with the pale spot near the middle of cell 7 



continued in cell 8. 



7 (16). Hind wing below : middle spot in cell 7 not joined to that on 



the transverse vein, or at most only touching it in a point. 



8 (15). Hind wing below with the apical third of cell 8 dark. 



9 (10). Hind wing below sordid yellowish green, pale spot on the 



transverse vein with sharp projecting angles orbifer, Hubn. 



10 (9) . Hind wing below tile- red (more or less bright) or pale red-brown. 



11 (12). Hind wing below with the pale spot on the transverse vein not 



produced inwardly ; wings strongly tinged with sordid 



yellow therapne, Rbr. 



12 (11). The pale spot on the transverse vein of hind wing below produced 



both outwardly and inwardly. 



13 (14). Such spot and that in cell 1 b but little intensified ; hind wing 



below tile-red sao, Bergstr. 



14 (13). Such spots much intensified, silver-white ; hind wing below 



pale red-brown ali, Ob. 



15 (8). Hind wing below with the apical third of cell 8 pale .... geron, Wats. 



16 (7). Hind wing below with the middle spot in cell 7 broadly con- 



nected with that on the transverse vein by a triangular spot 

 in the base of cell 6. 



17 (18). Hind wing above with no pale spot in the middle of cell 7. No 



costal fold in the male phlomidis, H.-S. 



18 (17). Hind wing above with a pale spot in the middle of cell 7. 



Male with a costal fold. 



19 (20). No tibial hair-pencil in the male, but several short spines on 



the outer side of hind tibise cribrellum, Evers. 



20(19). Male with a tibial hair-pencil 1 . cynarce, Rbr. 



1 Fide Watson. There is no male of this species in coll. Elwes, and only one female. The latter can only 

 be separated from cribrellum by its name-label.
