ACONTIA, Ochsenheimer. 

 Acontia metallica. nov. sp. (Plate 2, fig. 7.) 



Anterior wings white; posterior wings entirely rather pale yellow. 

 At the costa at base a short blackish band more or less covered with 

 steel colored sub-metallic scales, which is sometimes continued below 

 the disc when it joins a broad subterniinal continued dark ferrugi- 

 nous band which is bordered inwardly with yellowish olivaceous and 

 shows some sub-metallic scattered scales forming irregular lines. This 

 band commences on the costa at apex staining the apical fringe and 

 leaves but a narrow portion of the lower terminal margin white ; basal 

 internal margin white ; a costal spot beyond the disc, sometimes obso- 

 lete ; a row of terminal dots ; lower fringes white. Posterior wings 

 yellow with a more or less continued terminal rather wide blackish 

 band; fringes yellow Under surface of both pair of wings yellow, 

 anterior pair largely marked with blackish in the center and in sub- 

 terminal space, posterior pair immaculate except a costal spot some- 

 times obsolete. 



Abdomen above very pale yellow, immaculate, beneath white, with 

 rows of central and lateral black dots, not exceeding posterior wings. 

 Head and "collar" blackish; palpi fringed with yellowish hairs; tegube 

 white ; thorax furnished with blackish sub-metallic scales forming a 

 large tuft behind; legs white marked with blackish, anterior tibiae 

 entirely blackish. Exp. 1.00 inch.

My figure represents that form of this species in which the basal 

 band is not continued below the disc to subterniinal band. This large 

 species mimics the genus JEJud?\yas, in its ornamentation and coloration. 

 It resembles the description of Acontia delecta Walker, but differs as 

 follows; there are no blue shades on anterior wings, the submarginal 

 band is not forked at the tip nor bordered by ferruginous but by a vivid 

 yellowish (dive-green ; the coloration of the under surface is the same 

 as that of the upper surface of posterior wings. The habitat of Mr. 

 Walker's species is unknown.
