segments blue on the sides, and also above, except the black 

 fciitral carina and the hinder partot" segment 3 ; the following 

 segments with terminal blue lateral spots, only distinct on 

 the third, si'venth, and eighth segments. t\)re wings 

 h}alinc, blackish in the costal area from the filth postnodal 

 cro.«5s-nervure, and from about half the distance between the 

 nodus and the black pterostigma the apical portion of the 

 wing is j)ur|)le to the tip, but leaving the inner margin below 

 the purple j)ortion dusky and shot with iridescent blue. 

 Hind wings purple from the seconil |)ostnodal cross-nervure 

 to the tip ; the inner marginal area, however, is only dusky 

 from half the distance from the quadrilateral to the purple 

 part of the wing, and as far below the latter. The purple 

 part of the wing is crossed by two rows of long iridescent 

 subhyaline spots : the outer row consists of a broad upper 

 one, a narrow middle one, and a broad lower one, divided by 

 two longitudinal nervures ; the inner row consists of three 

 long subhyaline iridescent spots, the middle broadest, but 

 with its upper half shorter than the lower ; besides these, a 

 similar long iridescent subhyaline spDt projects inwards into 

 the hyaline part of the wing from the midtUe of the purple 

 part. 



Two specimens ; one immature, in which the purple part 

 of the wing is much paler, the blue spots on the head and 

 abdomen are wanting, and the pterostigma is pale in the 

 outer half. 



Belongs to the group of R. perforata^ Perch.

A single male specimen, agreeing with C. melanurunif 

 De Selys, in size and in having 13 postnodal cross-nerviires, 

 but differing in the uniform colour of the abdomen and in the 

 wings being petiolated as far as the basal j)ostco3tal nervure, 

 in which chartvcters it agrees with C. coromandelianutn. 



PSLUDOLESTES, gen. nov. 



Wings petiolated nearly as far as the basal postcostal 

 nervure, which is placed nearly halfway between the level of 

 the two antenodal cross-nervures, or nearer the second ; 

 second antenodal cross-nervure almost corresponding with the 

 arculus, the sectors of which rise close together above the
