DC moderately incurved (rather strongly just behind R 2 ), SC 1 free, SC 2 
arising before SC 5 , R 1 separate, R 2 normal, M 1 separate (approximated 
to R 3 ). Hindwing with inner margin long, tornus rounded-prominent, 
termen straight or very slightly sinuate inwards from tornus to R 3 , here 
bluntly angled, thence more convex than in Thalassodes, approaching the 
shape of Cheroscelis rubricorpus Warr. ; cell short, DC little curved, 
C touching SC at a point near base, rapidly diverging, SC 2 short-stalked, 
R 2 normal, M 1 very shortly stalked. 
Type of the genus : Lophorrhachia niveicristata, n. sp. 
May be placed between Cheroscelis and Heterocrita , showing more the 
build and texture of the latter, but with no sign of excision between the 
:radials of the hindwing, stronger crests, etc. In my Key (Gen. Ins., 
fasc. 129) it separates off on p. 17, at 64, and if the tibial armature is as 
indicated above it must be further mentioned in footnote 3 on p. 14. 
Lophorrhachia niveicristata, n. sp. (PL XXV, Fig. 3). 
32 mm. Face blood-red, lower extremity white. Palpus dark red 
above, dirty white beneath. Vertex and antennal shaft white ; occiput 
green. Thorax and abdomen green above, white beneath and at anal 
extremity ; second to fourth abdominals each with a snow-white crest, 
the first two almost surrounded at their bases with bright red, the last only 
with a little red at its posterior extremity. Wings green, almost as bright 
as in Heterocrita koranata Feld., but rather thinly and smoothly scaled, 
costal edge of forewing white ; both wings with small red discal dot and 
fine red terminal line, the latter extending round apex and extremity of 
costa of forewing ; lines extremely fine and faint, being only slightly 
darker or greyer green, lunulate, the antemedian outward (present on 
forewing only), the postmedian inward, marked with small dark grey dots 
on R 1 , R 3 , M 1 , M 2 , and SM 2 (forewing also, still more minutely, on R 2 ) ; 
fringes white. Under surface whitish-green, unmarked, costal edge of 
forewing dirty white.

Heterorachis despoliata, n. sp. (PL XXV, Fig. 4). 
§, 28 mm. Closely related to devocata Walk., structure the same. 
Forewing with costa slightly more rounded, termen somewhat straighter, 
at least posteriorly, tornus in consequence more squared ; costal edge red 
and only narrowly, not fuscous (only a little spotted with fuscous) ; 
marginal yellow line exceedingly fine and not crenulate, the red line 
distally to it being also exceedingly fine and not thickened between the 
veins ; tornal blotch wanting ; fringe much paler than in devocata. Hind- 
wing with termen less convex than in devocata and scarcely showing even 
the very weak crenulations which (especially about the radials) are 
observable in that species ; terminal line and fringe as on forewing. 
Under surface also with the paler fringes. Abdomen dorsally strongly 
infuscated, as in some forms of devocata , but with the crests white or 
whitish, not (or only at their bases) fuscous.
