sei)arated for the greater ]i:ut ; first discal line tliiu, brokeu at the veins like the 

 iollowing lines, bars M'— M- of lines 3 and 4 heavier and closer together, often 

 forming a single patch ; oblique band as in sericeus in position, narrower in front, 

 more or less dilated distad ut R'-. The discal and snbmarginal obscure bands of tlie 

 jiindwing oi sericeus are also marked in omissa. 



Costal margins less marked with greyish white on nndoside than in sericeus, 

 the tawny colour more restricted and less bright ; brown distal border of liindwino' 

 with a distinct white line as in sericeus, the border widest between R- and U', not 

 upon R-. Abdomen, below, less l)right tawny, and breast more olivaceoih^ tiian in 

 the j)revious insect. 



c?. Tenth sternite (PI. XLIV. f. 24) slightly widened apically. Process of 

 liarpe (PI. XLVIII f. 24) less triangular than in the preceding species, the hinder 

 edge not so heavily dentate, the teeth being confined nearly to the very edge of tiie 

 process. Left process of penis-sheath (PI. LV. f. 21) nearly horizontal, less 

 oblique than in sericeus and the following species.

S ? . Chestnut-brown above, shaded with grey, the dark markings of thora.x 

 and abdomen (piite indistinct ; breast olivaceous ciimamon-rufous, underside of 

 abdomen ferruginous. 



Wings not dentate, or the teeth barely vestigial : less elongate than in omissa. 

 I '/>/ier.si(/e, ibrewing : resembling omissa, oblique discal band widened distad 

 between R- and M^, its proximal edge more curved than in omissa, first discal line 

 also weak, barely more distinct on the dark ground, bars M^ — M- of discal lines 

 :i and 4 not heavier than the others, nor closer together; grey subapical area sharply 

 limited at R- in a similar way as in naffa, not extending beyond this vein ; antemedian 



band more or less filled in with brown. Hindwing less olive-grey than in hik/u 



-.111(1 omissa ; disc somewhat cinnamon-rufous along the rather distinctly marked 

 cliestnnt-olive distal marginal band ; a faint discal line from costa to anal angle. 



L'liilerside : outer disc of forewing and disc of hindwing more reddish tawnv 

 than in sericeus, and far more so than in omissa ; grey costal scaling not more 

 conspicuous than in omissa ; grey scaling within distal marginal border of forewing 

 diffuse, less distinct than in the previous species. 



(?. Lobes of tenth sternite almost pointed. Process of harpe similar to that 

 of sericeus, the ventral edge dentate (PI. XLVIII. f 27). Penis-sheath more 

 strongly and obliquely rounded than in the other species, the armature helmet-like 

 (PI. LV. f. 22). 



?. Vaginal plates (PI. XLl. f. >) transversely folded; orifice free, subapical.
