The forms arranged under this genus are very puzzling, arid 

 until extensive breeding experiments are undertaken it will be 

 impossible to attain any certainty as to whether there are two or 

 a dozen distinct forms. This difficulty is especially felt when 

 dealing with the females of the forms in any large collection, 

 and personally I have only tentatively managed to pair many 

 specimens. The males it is possible, following de Niceville, to sort 

 more or less satisfactorily into two groups. I have, therefore, 

 provisionally adopted an arrangement under two forms, C. tJietis, 

 Drury, and C. bulls, Doubleday and Hewitson.

* De Niceville takes the extension or non-extension along the dorsal margin 

 of the terminal black border on the upperside of the fore wing as a definite 

 marking by which the two groups of Curetis can be distinguished one from the 

 other, but that character does not apply to the females. The markings on the 

 underside, on the contrary, though often indistinct, are alwavs traceable, and 

 they apply to both sexes. For the rest, de Nice"ville's synopsis of the cha- 

 racters that distinguish the various named forms (?) or varieties (?) is the best 

 snort presentment of the differences that exist between what may be mere 

 varieties, or again may hereafter take specific rank. I have, therefore, largely 

 taken advantage of it, adapting the terminology to that used in the present 

 work.
