tinued to vein 2; a faint fuscous discal shade and mark. Hind wings with a

? . — A large species with hairy eyes and the oviduct barely visible. It is a 

 species of singular appearance, and resembles the European D. caesia and the 

 European species of Polia (such as nigrocincta H.-S. fig. 482). Hoary gray 

 over fuscous the markings faint, with a tinge of yellow accompanying the 

 large coucolorous ordinary sjiots and the transverse lines. The narrow ter- 

 minal space and the median, a little freer than the rest of the wing from pale 

 scales. Subterminal line preceded by large and vague fuscous cuneiform 

 marks. Terminal black dots distinct. Fringes fuscous and pale with a whit- 

 ish basal line. Hind wings fuscous with a median shade line and pale fringes, 

 Body parts concolorous with the wings. Beneath whitish, very sparsely irro- 

 rate with dark scales ; a common undulating fuscous line and indistinct discal 

 mark on hind wings. ,

3 ? . — Eyes naked, with lashes. Fore tibiae with a claw, else the tibiae 

 unarmed. Collar rather wide and slightly produced in front. Size of the 

 European O. confusa, H.-S. figs. 44, 45, and evidently exceedingly near that 

 species. Apparently a darker species, and without so apparent a yellowish 

 tint on the fore wings and none on the hind wings, which have broad fuscous 

 borders, soiled veins and whitish bases with slight discal marks. Beneath 

 evidently darker, peppered with black dots, and with the primaries wholly 

 fuscous. The fore wings above are dark fuscous with an even neutral yel- 

 lowish tinge ; lines fine, black, waved and double. Ordinary spots concolorous, 

 rounded, reniform with a blackish stain. Median shade line nearly perpendic- 

 ular, angulated back to costa above the reniform. Median space wide, the t. p. 

 line roundedly exserted much beyond the cell, approaching the subterminal 

 line, the latter of the dull yellowish tinge of the wing preceded by irregularly 

 sized black cuneiform marks unequally distinct. Fringes fuscous, dotted with 

 black. Head and thorax above like fore wings, coarsely peppered with black 

 scales.
