fohjtes are also absent : -whether they are really absent from the Andaman 

 Islands and the other regions mentioned, and, if so, whether they ceased 

 to be developed or rather were exterminated as soon as the species spread 

 into regions wherein neither of the forms which its females mimict 

 exist, are interesting subjects for future enquiry.

No representative of the genus Eestia has been received from Mr. 

 de Eoepstorff, but we are indebted to Capt. G. F. L. Marshall, S.. E., for 

 the gift of a specimen which that gentleman had received from Colonel 

 Cadell, Chief Commissioner of the Andamans and Nicobars, but which 

 does not agree with Felder's figure and description of Hestia ac/amarscliana, 

 the only species of the genus hitherto recorded from those islands, either 

 in the extent and relations of the black markings or in the shape and 

 proportions of the wings ; the former being larger, more or less eoalescent 

 generally, and completely run together at the outer margin so as to form 

 a distinct black border to each wing, and the posterior pair of the latter 

 being broadly rounded off at the extremity and consequently not presenting 

 the peculiar egg-shaped outline so characteristic of these organs in all the 

 hitherto described Indian Hestias, e. g., H. Lynceus, H. Jasonia, etc., with 

 the latter of which Felder compares his species ; the specimen apparently 

 also differs from S. agamarschana in having the white of all the wings 

 everywhere more or less clouded with minute black scales. U. agamars- 

 chana, it is true, to judge from Felder's figure of it, has the posterior 

 wings a little less pointed, the anterior discal spots on the anterior ones 

 obviously more elongated, with more black in the cell and behind it, and 

 the markings generally larger than in S. Jasonia, and it is, as might 

 have been expected, more closely related to the specimen obtained by Col. 

 Cadell than to any other species ; but, large series of specimens having 

 shown us how extremely constant the different species or local races of 

 JLesiia are, we cannot unite the two, and we think that the differences they 

 j)resent are in all probability due to a difference of station, and that Heifer 

 may have obtained the specimen that served Felder for type on a different 

 island ; all the lepido])terous insects of late years received from the Andamans 

 having been obtained in the immediate vicinity of the settlement at Port 

 Blair, in an area therefore which is a very small fractional part indeed of 

 the Andaman group of islands, which extends through nearly four degrees 

 of latitude. We, therefore, propose to describe the specimen as a new 

 species under the name of
