ARGYNNIS VIII. 



ARGYNNIS ATOSSA, 4-6. 

 Argynnls Alossa, new species. 



Male. — Expands 2.5 inches. 



Upper side briglit yellow-fulvous, the base very lightly dusted brown ; hind 

 margins of both wings bordered by a single line, and that is the inner one of the 

 two usually seen in the group, there being no trace of the outer line ; no black 

 subinarginal spots on either wing, except on primaries, in the lower three inter- 

 spaces, in each of which is a small spot representing the apex of the usual ser- 

 ration; nor are there the usual rounded black extra-discal spots, except on the 

 lower four interspaces of primaries, and of these, the middle pair only are de- 

 cided black ; the black subapical patch is also wanting ; the discal and cellular 

 markings on primaries are light, and very much as in Adiante ; on secondaries 

 the mesial band is reduced to a series of abbreviated narrow bars, widely sepa- 

 rated ; the S-shaped spot at end of cell is slight ; fringes pale yellow throughout. 



Under side of primaries very pale fulvous at base to middle of cell, and in the 

 P-shaped spot, and the basal part of the median interspaces ; on this area the 

 black markings are repeated, reduced ; all the rest of the wing, in the cell and 

 to apex and hind margin, pale yellow-buff, the markings obliterated. 



Secondaries wholly pale yellow-buff, the basal area to the inner side of the 

 second row of spots scarcely darker than the rest ; all the spots faint, and with 

 no trace of silver, their inner edges slightly dusky. 



Body above concolored with the basal part of the wings ; beneath, the thorax 

 yellow-buff, the abdomen reddish-buff; legs reddish on the fronts, yellow be- 

 hind ; palpi yellow, the long hairs in front red ; antennte fuscous above, ferru- 

 ginous beneath; club black, ferruginous at tip (Figs. 4, 5).
