joining the first subcostal nervule to the costal nervure is 

 a feature present in Jainides, Hilbner. Structurally this genus 

 liai-dly differs from JamicJes, and what differences there are are 

 so slight that they can hardly be expressed; but the style of 

 colouration and markings will easily distinguish them. Type L. 

 (vJ'ianus, Fabr." (de Niceville). 



It will be noticed that Miskin* gives a list of seventeen species 

 referred to Lamjndes, Hiibn., not one of which can correctly be 

 placed in that genus, as defined by the authors he quotes; while 

 the two species that can structurally be referred to that genus he 

 has placed under Danis, Fabr. It appears from Miskin's 'Cata- 

 logue' that the main distinction he adopts between Lyctmia and 

 Lampides is the al^sence of a tail in the former case, and its 

 presence in the latter; but it may here be remarked that the same 

 species is often found tailed and tailless. The species given by 

 Miskin under Lanipida^ are referable to Nacaduha, Tdrucits, 

 ./amides, Everes, Wtica, Polyo7nmatus and Catochrysops. 



The two Australian species which structurally belong to this 

 genus are very different in pattern from the Indian forms, as 

 typified by L. celianus. In our species there are no strigte on the 

 underside, and they are much more allied to Danis (ThysonotiSy 

 Hiibn.}. 



The two species may be distinguished as follows : — 



A. Male above silyeiy-blue; beneath, in both sexes, with white 



spots on outer marginal borders of both wings; no bands.... cadesds. 



B. Male above pale blue; beneath, in both sexes, with hindwing 



showing a series of conical black spots; bands on forewing, 



and a costal white line cdeuas. 



A tail is present in both species.

This species is recognised by the light silvery-blue of the male, 

 and the black of the female, in both sexes with white central
