 tout cas, il maintient les deux espèces séparées et nous ne sommes 

 l)as lom de partager son opinion. Toutefois, comme nous ne possé-

 ce très délicat litige, nous nous bornons à mettre sous les yeux 

 du lecteur les descriptions et les figurations originales que nous

Voici tout d'abord la description d'Aiirorina par Butler; c'est 

 la première en date. 



« Cymatophora AURORINA, n. s. — Allied to G. scrïpta of 

 North America, from which it differs m its smaller size, darker 

 coloration, the distinct pink gloss on the upper surface of the 

 primaries, the more contracted basai area of thèse wings, due to 

 the inangulation of the inner white border of the central belt ; the 

 anal area is occupied by a large grey rounded spot, shading into 

 rust-red along its inner border, which is bounded by a curved 

 white stripe (the outer limit of the central belt) ; above this spot 

 are the ordiinary black, crinkled, discal lines, which are four in 

 number, parallel as usual, wider apart, much less deeply and less 

 acutely zigzag or undated than in G. scrïpta, and terminate at 

 the first médian branch instead of running through the central 

 belt to inner margin; the abbreviated gravel-brown lines on the 

 opposite side of the central belt are also whoUy wanting in the 

 Japanese species, but the costal border above the usual discoidal 

 spot is much more obscured by transverse dusky stripes; the fringe 

 of ail the wings is golden brown tipped with white; the secon- 

 daries are shining f uliginous-brown, with the external third dusky ; 

 below the wings are similar in pattern to G. scnpta, but the ground 

 color is shining greyish brown instead of sordid creamy whitish; 

 expanse of wings, i inch 5 lines. »
