<S ? . Ri'cou:nisal)Ie by tlie presence of a large suljbasal patch at the costal 

 margiu of the forewiiig, the mesial line on the abdomen developing in the <? into 

 a patch upon the eighth seiifment, the strong curvatnre of the submarginal line of 

 the forewing, this line reaching the edt;e of the wing at M-, and by the posterior 

 bars composing the discal line of the forewing being obviously arched. The forewing 

 is ochraceous clay colour above in the c? ; nearly burnt umber brown, shaded with 

 grey, in the ? . A few spines on the foretibia externally near the apex. Underside 

 of wings much shaded with tawny in the basal area, especially in the ? , abdomen 

 and wings, below, much less yellow than in sericeipennis -auA placida. 



cJ. The eighth abdominal sternite (PI. XXII. f. 28) is mesially very slightly 

 sinuate, the sinus limited on each side by a small tooth. The penis-sheath 

 (PI. XXX. f 10) is dorsally gradually narrowed to a point ; it is devoid of any 

 additional armature. The harpe (PI. XXXI. f. I'J) has a very heavy, strongly 

 curved, submesial hook (/>/«), which is the distal prolonged part of a double 

 subme>ial ridge ; the ventral process (pc) is curved downwards, ratlier blunt, finger- 

 like. The tenth sternite is mesially lobed as in sericeipennis (PI. XXIII. f 7). 



?. Eighth tergite deeply incised. Vaginal plate similar to tliat oi' sericeipennis 

 and scliauj'elbergeri, the mesial lobe narrower (PI. XV. f. 3). 



Early stages not known.

<J. Resembling maculifera, more reddish in tint. Abdomen with middle line, 

 which is dilated to a patch on the eighth tergite. Forewing above with large 

 subbasal costal patch, submarginal line vestigial, with grey border ; hindwing more 

 distinctly dentate, margin chestnut, not black, few speckles. Underside of body 

 and wings rufous tawny like the upperside of the hindwing, lines on disc of fore- 

 ami hindwing slightly deeper in tint, no distinct speckles, no submarginal 

 line on forewing, grey marginal area broad. Eighth abdominal sternite rounded. 

 Tenth tergite (PI. XXII. f 30) with dorsal a])ical surface more slanting 

 than in maculifera. Harpe (PI. XXXI. f. 20) similar to that of sericeipennis 

 in the submesial ridge consisting of two dentate lamellae which are together 

 produced into a cone of which the tip curves ventrad ; distal process spoon-sl)aj)ed 

 as in maculifera, liturata and substriyilis substrigilis, the ]irocess less broad than 

 in these insects. Penis-sheath (PI. XXX. f. 14) curving dorsad, with a dorsal 

 row of teeth, apex truncate ; a stronger chitiuised ventral fold bearing three heavy 

 teeth.
