NOVITATES ZOOLOalCAE XXII. 1915. 301 



Al. ant. long. 14'5 mm., lat. 5'8 mm., marg. ext. 6 mm. 



llab. Mapiri, Bolivia, 1 <? received from Messrs. Staudinger and Bang-Haas. 



Body glossy green, with cyaneous reflections in certain lights. Upperside of 

 antenna deep blue in proximal half, then bright glossy green-bine, apex l)lack in 

 onr specimen. Tongae brown-black with pale apex. 



Wings nearly shaped as in Seri/da constans Edw. (1881), but distal margin of 

 forewing somewhat less obliijue, i.e. shorter, and that of hindwing rather longer. 



Upperside : forewing dull green, densely scaled, distal margin and fringe blue- 

 black, extreme costal and hind edges blue-green, costa proximally glossy, distally 



cyaneous. Hindwing uniformly brown-black, with very slight green and blue 



reflections in certain liglits. 



Underside of forewing greenish blue, slightly glossy, proximal half more green 



and more glos.s)' at costa and in cell. Hindwing uniformly bluish green, more 



glossy than outer half or two-thirds of forewing. 



The reddish purple tint on body and wings of our specimen is due to discoloration. 



10. Urodopsis dryas spec. nov. 



? . U. pnsillae similis, parum major, nitidior, antennis alisqne aijticis cyaneis, 

 alarum posticarum costa mediana inferiore basin magis approximata. 



Al. ant. long. : 7"3 mm. 



llab. Rio Grande do Sul, S.E. Brazil, 1 ?, received from Messrs. Staudinger 

 and Bang-Haas. 



The two original specimens of pusilla in the British Museum are very worn, 

 but there is a third, fresh, example presented by Mr. Kaye. All these agree in 

 neuration, diifering from dnjas in the two median veins of the hindwing being more 

 distal and the distance one from the other more than twice as large at the outer 

 margin as at the cell. The colouring of the fresh specimen oi pusilla, moreover, is 

 much duller than in dryas, there being hardly any gloss on the forewing. 



In dri/as the antenna, head, pronotum and patagia are purplish blue, while the 

 rest of the body has a somewhat greenish blue metallic tint. Hindwiug semi- 

 transparent, somewhat iridescent in certain aspects, the scaling purplish blue. 



Tongue and naked tip of abdomen pale yellow. 



Neuration : Distance between median veins of hindwing less than twice as long 

 at the distal margin as at the cell, that between upper median and lower radial 

 about one-fourth shorter at the cell than at the margin. 



Antenna ( ? ) strong, nearly reaching to apex of cell, with short pectinations on 

 the outer side (towards the wing) and teeth on the inner side, both as densely scaled 

 as the shaft, the teeth lying so close together that the antenna appears to have a 

 deep channel along the under surface.
