As there appears to be some little confusion respecting these 

 white species of Teracolus, I may briefly diagnose them as follows : — 



T. vestalis expands 20-24 lines; border of secondaries above 

 broad in both sexes; wings below sulphur-yellow, the apex of 

 primaries and entire surface of secondaries in the female occasionally 

 irrorated with grey and washed with mustard-yellow, the secondaries 

 also frequently with an oblique discal series of olive-brown spots. 

 May. 



T. puellaris expands 17-21 lines; border of secondaries above 

 varying in width ' ; female often pale yellow above ; male below 

 usually of a brighter yellow than T. vestalis, and with narrower 

 black discal spots ; the apex of primaries and entire surface of 

 secondaries in the female beloio flesh-coloured ; the outer border of 

 secondaries darker, and limited by a complete angular discal series 

 of brownish spots. April and May. 



T. ochreipennis expands 16 to 20|^ lines; border of secondaries 

 above rather broad in both sexes ; both male and female white 

 above in all specimens which I have seen ; the apex of primaries 

 and entire surface of secondaries in hoth sexes beloiu ochraceous, the 

 secondaries with rather darker border, limited internally by two or 

 three brownish spots, which sometimes, however, are obsolete. 

 November.

Var. Orange apical patch wider in both sexes, its inner black- 

 brown boundary becoming obsolete towards the costal border in the 

 male.
