34. Anthocharis Delphine. 



Anthocharis Delphine, Boisd., Sp. Gen. Lep., I, p. 577, 



[n. 28. 



$ . " White ; with orange apical patch. Fore-wing : orange 

 at apex strongly sinuate internally, rounded and dentate 

 externally, the lower portion of the curve of its inner edge 

 lightly defined with blackish, its outer edge bordered with 

 brown ; a small, central (disco-cellular ?), black spot. Hind- 

 wing : hind-margin intersected with black marks or spots. 

 UNDER-SIDE. Fore-wing: a small, central, black spot; 

 apex pale-reddish. Hind-wing : pale-reddish, with a small, 

 central, black and orange spot ; a faint indication of a sinuate, 

 transverse, dusky band. 



? . About the size of $ . Fore-wing : orange spot bordered 

 internally by a transverse black stripe, which is sometimes, 

 however, passed by part of the orange ; inner-margin some- 

 times blackish. Hind-wing : traversed by a sinuate, macular, 

 blackish stripe, commencing on inner margin of fore- wing, as. 

 in the allied species ; hind-margin intersected with black, as 

 in the $ . UNDER-SIDE. Similar to $ , but the reddish 

 markings more ferruginous in tint. Hind-wing : transverse 

 stripe more strongly marked." Boisd., Sp. Gen. Lep., I, 

 p. 577. 



An Anthocharis labelled as Delphine, in the collection of the British 

 Museum, I cannot reconcile with the above description of Dr. Boisduval's, 

 which, as in other instances, for convenience of reference, I have moulded 

 into my usual form of description. There is, however, in the same collection, 

 an Anthocharis apparently referable to this species ; it seems to be a female, 

 and possesses the distinctive character of the apical red passing within the 

 internal black edging, near costa. A Butterfly in my own collection, also, 

 comes nearer to the description of the male of this species than any other ; 

 as likewise does a specimen from Natal, in the South African Museum. In 

 both of these, the red passes considerably within the inner black edging, 

 which is reduced to a short black curve from hind-margin, not extending 

 above first median nervule ; and there is a blackish band along inner-margin, 

 as well as on costa of hind-wing. 



An Anthocharis in Mr. Andersson's collection approaches very closely to 

 Boisduval's description of the $ Delphine, but the inner-margin of lore- 

 wing and costa of hindwing are both banded rather widely with blackish. 

 The underside of hindwing, too, is yellowish-white instead of pale-reddish, 

 but this is not a difference of any importance.* 



* A subsequent examination of a series of specimens in Mr. D'Urban's 

 collection has convinced me that the above-noted individuals of Anthocharis 

 are truly referable to A. Delphine. The $ varies from specimens pos- 

 sessing the very faintest traces of an inner-marginal streaik to those as 

 strongly-banded as Mr. Andersson's example. ' The ? specimens are 

 mostly very blackly and broadly banded on both wings. Mr. D'Urban 

 found the insect abundantly " from Port Elizabeth to King William's Town," 

 appearing " from June to August and from October to March,"
