On the Purine Butterflies of the Genus Daptonura. 347 



XLVIII. — N^otes on the Pierine Butterflies of the Genus 

 Daptonura, with Descriptions of new Species. By A. G. 

 Butler, Ph.D., Senior Assistant-Keeper, Zoological De- 

 partment, British Museum. 



In carefully supervising the synonymy of Daptonura I noted 

 that the outline of the wings, tlie width of the outer borders, 

 and the inner edging of the latter appeared to be constant and 

 reliable characters; but the mere tint of the wing-surface 

 varied from white to brimstone and from brimstone to saffron, 

 these modifications being best illustrated by such species as 

 D. florinda and D. isandra. 



In D. limnoria^ Godt. {limnohia, Swains.), the secondaries 

 of the male vary in tint from pale brimstone to canary-yellow, 

 but the orange on the border is invariably represented by a 

 series of saffron or orange spots. Hiibner's figures (Samml. 

 exot. Schmett. ii. pi. ccxxxii.) represent a very distinct 

 species, for which, years ago, I proposed the name D. Hiibnerij 

 writing it upon a label and pinning it into the collection ; but 

 if I published tlie correction it has never been quoted, and 

 consequently I cannot refer to it. 



Hiibner's insect differs in both sexes from D. limnoria, 

 as will be at once seen by comparing Swainson's admirable 

 illustration of the latter with the plate in the * Sammlung.' 



Daptonura Hiibneri. 



(^ . Decidedly smaller than D. limnoria, the black apical 

 border narrower, with regularly dentate-sinuate inner edge ; 

 the secondaries bright sulphur-yellow, with broad orange 

 outer border and linear black edging. 



$ . Smaller than that sex of D. /tmnoria, the black cunei- 

 form bar across end of cell connected by a streak (which 

 passes along the third median branch) with the black outer 

 border ; the latter narrower on the costa than in the common 

 species and gradually decreasing in width to inner mai-gin ; 

 the secondaries as in the male, excepting that the orange 

 external area and black edging are wider. 



cJ, " Rio R." In coll. Hewitson. 



The female I know only from Hiibner's illustration ; it is 

 said to come from Brazil. The locality is probably Rio Real 

 in Northern Bahia. 



Daptonura incequalisj sp. n. 



Allied to D. leucanthe ; decidedly smaller, the outer margin
