Orochion undulosa spec. nov. (figs. 825, 830, 831) 
(j) 9 — li mm. Head snow-white, tuft on vertex mixed with fuscous, 
face shining fuscous-whitish. Antenna whitish becoming fuscous on 
posterior half, eyecap snow-white. Palpus greyish-white. Thorax white, 
a narrow longitudinal median bronze-fuscous line; somewhat suffused 
similar lines, just at the border of tegulae, minute. Abdomen and legs 
whitish, tarsi with basal halves of segments greyish, anterior leg rather 
infuscated throughout. Fore wing narrowly lanceolate, apex produced, 
narrow, acute, somewhat curved downward, termen extremely oblique, 
appearing sinuate. Snow-white, markings tawny-fuscous with golden- 
coppery shine. A narrow suffused streak along basal third of costal edge; 
from beyond this to beyond 2 / 3 of costa five outwardly oblique tolerably 
equidistant transverse streaks becoming longer posteriorly, fourth reaching 
to middle of disc; fifth streak merging in a moderate transverse direct 
band beyond 3 / 4 reaching to termen, followed by a narrower transverse 
band of white ground colour; apical area and cilia beyond this transverse 
band pale bronze with three transverse white fasciae extending over cilia, 
ultimate fascia broad, including a well-defined, jet-black, round dot in 
apex; dorsal markings much darker than costal: four irregular, elongate, 
inwardly oblique marks in the horizontal series above dorsum, well or 
not touching it, from beyond base to slightly beyond middle of wing; 
ultimate pah of these marks sometimes interconnected, so as to form a 
prostrate-S-shaped mark, with posterior extremity erect, so as to form a 
well-defined, strongly inwardly oblique slender transverse mark, reaching 
to apex of third costal streak and forming together with this a strongly 
angulat-e transverse fascia. Both dorsal and especially costal markings 
sometimes ill-defined or almost obsolete. Cilia around apical fifth as 
described, along dorsum whitish. Hind wing whitish-grey, cilia whitish. 
Ovipositor adopted for cutting or boring purposes: lobes naked, strong, 
on inner surface dentate : anapophyses, strong rods, united, so as to form 
a cuspidate process ventral of ovipositor lobes. Limen, a weak triangular 
plate with acute top. Ductus bursae with a small invert-conical plate at 
base. Signa, two long concave bands gradually dilated distad. (Slide no. 
1093 D, holotype.)

Orochion sororcula spec. nov. 
$ 13 mm. Head whitish (partially denuded). Antenna bronzy-grey,

with white, tegula white. (Abdomen missing.) Legs pale fuscous, posterior 
tibia pale ochreous with a yellowish postmedian band, tarsus pale fuscous, 
articulations darker ringed. Fore wing narrowly lanceolate, apex produced,
