excision between radials and the convexity slightly greater on either side 
of this excision than towards the angles of the wings ; base of costa in 
expanded, beneath wide a moderately large fovea partly overlapped by 
hairs, and C swollen, curved, overhanging a deep scaleless hollow between 
this vein and SC ; in $ normal ; C diverging rather rapidly after brief 
approximation to cell ; cell about one-half, DC slightly incurved, SC 2 
separate, R 2 wanting, M 1 separate. 
Type of the genus : Gyalomia elalina n. sp. 
The species, which are closely allied, show the facies and type of scaling 
of a small, smooth-margined Boarmia , but the structural characters are 
more nearly those of Cabera (= Deilinia). The true genetic position is 
uncertain. 
Gyalomia elatina , n. sp. (PL XII, Fig. 23). 
£ 5, '22 mm. Face fuscous, whitish below. Palpus ochreous whitish, 
marked above with fuscous. Vertex ochreous whitish, occiput narrowly 
blackish. Antennal shaft black, becoming gradually pale beyond middle. 
Thorax pale brown-grey, paler beneath, pro- and mesothorax each with 
two large blackish spots, occupying most of their dorsal area ; patagia 
pale brown-grey, tegulae mostly blackish ; abdomen ochreous white, 
dorsally fuscous at base and belted with fuscous throughout. Foreleg 
blackish on upper side. 
Forewing ochreous white, with fine fuscous speckling in most parts, 
clouded with brown basally and with brown distal clouding, gradually 
widening, from R 1 to tornus ; lines blackish, thick ; antemedian oblique 
outwards from costa, almost lost in a black irr oration which largely over- 
spreads the basal area and is very strong along the median vein ; median 
line slightly curved, from midcosta to before middle of posterior margin ; 
an additional straight, very oblique line starts from the latter margin 
midway between base and median line, which it joins in cell : postmedian 
rather more strongly curved and with a weak sinus inwards in middle, where 
it is thinner and less distinct than at margins ; a small dark patch at 
apex, containing the beginning of a white subterminal line, and narrowly 
connected with a wedge-shaped dark mark about R 1 which is margined 
with white ; pale sub terminal again traceable on the brown terminal 
cloud ; cell-spot small but distinct ; the white area distallv and posteriorly 
hereto almost entirely free from dark dusting ; terminal line black, inter- 
rupted at vein-ends ; fringe dark-mottled. Hindwing ochreous white, 
dusted like forewing and irregularly clouded with pale brown distally ; 
a blackish mark at base, a slightly curved antemedian line continuing 
the median of the forewing ; a, weaker postmedian from abdominal margin, 
losing itself towards middle of wing ; a weak sub terminal, becoming thick 
and strong towards tornus ; discal spot distinct ; termen and fringe as 
on forewing. Forewing beneath blurred ochreous whitish, with costal 
edge suffused with greyish ; median line present, accompanied by obscure 
clouding; cell-spot distinct; a fuscous distal border of 2-3 mm. width, 
containing traces of a pale subterminal. Hindwing beneath cleaner whitish, 
marked like forewing except the obscure clouding ; pale subterminal line 
rather more distinct.
