 hairs; pectus with the hair mostly grey ; tarsi with white rings. Fore-

 very ill-defined antemedial, medial and two postmedial waved lines ;

 beyond the cell between veins 6 and 4, and a small triangular post- 

 medial spot above vein 6 ; a subterminal series of white points in 

 the interspaces with a small rufous spot before the one above vein 4. 

 Hind-wing black-brown, the costal area whitish towards base, the 

 inner area clothed with large rough leaden-blue scales and crossed by 

 numerous indistinct waved black lines with very ill-defined pink

Type in Brit. Mus. A good deal rubbed. 



The geniismust be assigned to the family EUSCHEMONID.E 

 represented by the single species Euscliemon rafflcsia, 

 Westw., from Australia, that however is a typical Hesperid, 

 except in having a strong frenulum and retinaculum, 

 whilst the present genus has veins 7, 8, 9, 10 of the fore- 

 wings stalked, in Easrkcmon and all Hesperiad.^ all the 

 subcostal veins arising from the cell. Aijo^rrogoncs must 

 therefore be considered a development from the Lepido- 

 pterous stock at the point where the butterflies branched 

 off. 



In what part of the world the butterflies first arose 

 we cannot of course say, but all the surviving forms at 

 all closely related to their point of origin belong to the 

 scattered remnants of the old Antarctic fauna ; we have 

 first the Castniadai found in the Neotropical region and
