152 ME. G. T. BETI1UNE-13AKEE: A EEVISION OF THE 



primaries extending over the discal, submedian, and two-thirds of the median areas. In 

 the secondaries the white patch is confined by the upper discoidal and submedian 

 nervures and is not in the cell, except at its outer extremity, where it is closed by a dark 

 spot. At the base of both wings there is a bright pale azure-bine scaling, extending 

 half over the cell and more than halfway along the inner margin of the primaries, but 

 almost confined to the cell in the secondaries. Tail brown, tipped with white. 



This is a very distinct species and should be recognisable without the least difficulty. 



Dr. Staudinger sent me one female with his collection, and I found three males in 

 the Tring Museum, these being all the specimens I have seen.

6 ■ Upperside : both wings pale silvery blue not lustrous, with a lilac shade in a side 

 light; primaries with a fine dark eosta and rather wider outer margin; secondaries 

 with a greyish eosta not very broad, posterior margin narrow ; tails black, white- 

 tipped. Underside: primaries greyish white, becoming greyish brown on the outer 

 margin, with no markings at all except a trace of a submarginal band ; the subdiscal 

 area is darker grey. Secondaries whitish, with a dark grey spot closing the cell » 

 transverse band composed of eight dark grey isolated spots, with the exception that the 

 seventh and eighth touch each other ; submarginal and marginal rows distinct, the latter 

 fine ; a dark spot on each side of the tail. 



?. Upperside: both wings white, with very broad borders all round. Underside 

 like that of the male. 



This species is near wildei Miskin, but is smaller, with narrower borders, rather 

 different colour, and darkish grey beneath, not white, whilst the spots are also different. 



The specits described under the name courvoisieri 1>> Kibbe (/. c.) is without doubt 

 Felder's insect.
