acutely cleft near anal anfjle, posterior margin with a long tail-like appendage at apex of subinedian 

 nervure, and a short one at apex of lower median nervuie. Costal uervure not quite reaching apes of 

 wing, the subcostal nervules bifurcating a little before the end of cell, first and second median nervuleK 

 with an apparently common origin near end of cell. Palpi long and porrect, second joint robust, clothed 

 with short adpressed hairs and extending more thau half its length in front of eyes, apical joint moderately 

 slender and about half the length of second ; antennae with a very slender and gradually formed apical 

 club, ti ffs mittihtctt. 



Although the name of this genus has appeared before/ it lias not been previously 

 described, and was used by Mr. Waterkonse in error* I originally described the typical species 

 under the name of lolaus (Purlisa) tjiyanteu$ t \ the name Purlisa being a proposal of Mr. Moore, 

 but in 4 Aid' the name "Iolaus" was discarded, and the hitherto unpublished name of 

 "Purlisa" alone substituted*

Wings above brilliant cerulean-blue ; anterior wings with the basal third of costal margin dark 

 greyish-fuscou8 p and from which the whole apical area (concave internally) to near apex of inner margin is 

 black ; posterior wings with the outer margin broadly black, the fringe greyish -white, abdominal margin 

 greyish, anal angle fuscouB, irroruted with bluish scales, outwardly margined with white, and followed by 

 a dark line separating the fringe, taiMike appendages fuscous, margined with greyish-white. Wings 

 beneath smoky-grey, both wings crossed by a submarginal narrow dark fascia, commencing on anterior 

 wings about midway between end of cell and outer margin, sharply defined outwardly and evanescent 

 inwardly, waved but entire on anterior wings, and deeply sinuate towards anal angle of posterior wings ; 

 a paly marginal border containing some obscure elongate spots on interior wings and a double row of 

 smoky elongate spots on posterior wings ; a black submarginal spot faintly margined with bluish between 

 the second and third median nervnlefl, and a larger spot of the same colour at anal angle ; fringe as above. 

 Body ami legs more or less concolorous with wings.

This appears to be an exceedingly rare species. I possess but one specimen, and the 

 only other example vs-hich I have seen is a much mutilated and unlocalised one in the 

 collection of Mr. F. Moore, where it has been for the last twenty years. During this time it 

 has frequently excited the interest of the owner and the late Mr. Hewitson, but its condition 

 prevented its proper determination.

Anterior wings subtriangular, the costal margin arched and convex, tho outer margin nearly 

 straight, the inner margin nearly straight, but slightly concavely sinuate. Costal nervure terminating
