Genus STROBISIA, Clemens. 



STEOBISIA AURAKTIACA, Walsingham (Plate 209, Fig. 6). 

 Head dark grey; palpi cinereous, the apical joint very long and slender, acutely 

 pointed ; antenuEe cinereous, spotted above with fuscous. Forewings bright orange- 

 red ; a slender metallic streak, varying according to light from steel-blue to bright 

 green, extends from the base along the costa rather more than one-third the length 

 of the wing, whence it diverges obliquely downwards and terminates on the discal 

 cell ; its costal angle is followed by a short black oblique costal streak, and this again 

 is ibllowed after a rather wider interval by a bright steel-blue spot, beneath which is 

 a still larger spot of the same colour reaching nearly to the dorsal margin, both edged 

 with black scales ; beneath the lirst costal metallic streak is a similar streak also from 

 the base, running along the fold to its middle, and below this again, near the dorsal 

 margin, are a few similar steel-blue metallic scales; beyond the outer spots the whole
