NOTES ON THE VARIETIES OF PERONEA CRIS- 

 TANA, Fab., LATELY IN THE COLLECTION OF 

 THE LATE J. A. CLARK; WITH A REVISION 

 OF THE NOMENCLATURE. 



By Sydney Webb. 



(Continued from vol. xliii. p. 268.) 



Cristana, Group a,, Addendum. 



Nigropunctana, Clark. — Similar to proxanthovittana, as now 

 determined, but the central tuft is large and dark brown, instead 

 of fulvous. South {in litt.) is of opinion that nigropunctana, 

 Clark, and full- ostri ana, Desv., are referable to the striana group, 

 and states that the former only differs from the latter in having 

 a more complete fulvous streak on the inner margin. He 

 regards fulvostriana as a form intermediate between striana, 

 Haw., and nigropunctana, Clark. 



Desfontainana Group. 



Fulvous dash along centre of wing from the base to the 

 fulvous button. 



[Albovittana, Steph. — White head and thorax, white vitta. 



Fulvocristana, Steph. — Yellow head and thorax, ochreous 

 vitta. 



Consimilana, Steph. — Vitta consisting of approximating ashy 

 lines. 



Desfontainana, Fab.] 



Sericana, Hub. nee Dup. — Similar to desfontainana, but no 

 central tuft ; or, if it be present at all, it is extremely small. 

 No vitta. 



Ulotana, Clark. — Bluish black. Vitta two striate ashy lines 

 below the deep rusty red central streak, which terminates in the 

 similarly coloured large central tuft. Apparently quite distinct, 

 but in the specimen Clark took for his type the vitta is entirely 

 absent. In his series the two forms are about equally divided 

 in numbers. That with vitta appears to agree with sericana, 

 Dup., but the latter name had already been adopted by Hiibner 

 for another form ; it must therefore be dropped in favour of the 

 later one of Clark's, which will include both modifications of the 

 form, unless we name the striated one Jlammeana. 



Cristalana Group. 



Much variegated with light and dark brown, occasionally with 

 white markings, or yellow vitta. 

 [Subcristalana, Curt. J
