216 AUSTRALIAN RIIOPALOCKRA : LYC.ES ID.E, III., 



Jamides, Hiibner. 



Verz. bek. Schmett. p. 71, 1816; Moore, Lep. Cey. i. p. 86, 1881;

Costal nervure very sliort, ending on costa before end of cell; 

 costal nervure in the type species, ./. bochus. Cram., connected 

 with 1st subcostal by a short spur in the same way as in the 

 genus Lamjndeti. In J. phaseli, the commoner Australian species, 

 this spur is very short, if present at all, the costal nervure 

 approaching and touching 1st subcostal nervure but not being 

 anastomosed with it. This genus on the underside is very allied 

 to that group of Nacaduba represented by N. atrata, Horsf., and 

 X. berenice, Herr.-SchfF,; it has a very wide distribution through 

 the Indo-Malayan and Austro-Malayan regions. I can recognise 

 only two species from Australia, one of which is common, the 

 other rare. The undersides of both species are very much allied, 

 ])ut J. i^haseU is purple on the upperside, and J. aiwirauye is light 



silvery blue.

^. 15mm. Upperside. — Foreiviug pale almost metallic 

 silky blue, with brown costal area, widest at apex, and 

 outer margin. Hindiving pale almost metallic silky blue, with 

 brown costal and outer margins, the latter marked externally by 

 a white line and internall}^ by a series of pale bluish crescents 

 almost dividing the margin into spots, the caudal spot being 

 darkest. Tail long, filamentous, tipped with white. 



Underside brown, with markings as in ./. phaseli, but the 

 white borders much more prominent. 



9. 16mm. Upperside very similar to ,J, but the blue 

 much deeper and less silky. 



Underside as in (J. 



Loc. — Darnley Island (Macleay Museum). 



It is with some doubt that I refer the Darnley Island specimens 

 to Druce's species. The male differs from the figure in having a 

 brown costa, and the markings of the underside more prominent;
