XY>.IPII ALICE CALLITHEA. 



(nearer the margins than in Batesii) ; clouded with bine black below the middle. 

 Posterior wing with the base the costal and inner margins (not the cell also as in 

 Batesii) orange to or beyond their middle, four rows of black spots parallel to each 

 other and the outer margin. 



Female (3, 6) with the anterior wings more rounded at the apex, the base orange 

 with a band of green (broad at the apex) near the outer margin. Posterior wing 

 with the base as well as the nervures slightly orange, the outer margin black with some 

 lnnular green spots. 



Var. Male (5). Anterior wing with the basal half (except the inner margin, 

 which is black) orange-carmine, the rest black, glossed with purple to an indistinct 

 white spot near the apex. Underside ash-colour. Anterior wing with the orange as 

 above, but lighter, with two black spots only. Posterior wing with the inner margin 

 and the apex orange. 



N.B. The lower disco-cellular nervule of the anterior wing of C. Markii joins 

 the median nervure beyond the base of the second nervule. 



Expan. 2-^q to 2f\j in. Hab. New Granada. 



In the Collection of W. C. Hewitson. 



Although fully convinced that the insects figured on the Plate represent two species. I should have 

 found it difficult to point out characters which would have satisfied either myself or others that they 

 are specifically distinct, had not Mr. Westwood pointed out the different curve of the disco-cellular 

 nervules. 



The antennas also seem to differ, if dependence can he placed upon the examination of a small 

 series of specimens. The cluh of those of C. Batesii is more pointed than in the new species. 



I think it will be seen that since the nervures vary in such closely-allied species as those before 

 us, when in others they differ in the sexes of the same species, they are of little worth (except when so 

 marked as in the genus PapilioJ as a guide to generic distinction. 



I have named this, one oT the most beautiful of butterflies, after Mr. and Mrs. Mark as a tribute 

 due to them from Entomologists in general for the zeal which has added greatly to our knowledge of 

 the Diurnal Lepidoptera. Personally I am indebted to their generosity for a large number of the most 

 interesting species which adorn my collection.
