Il02. GENUS PERITHALERA, NOV. GEN., PROUT 
Perithalera, nov. gen, Prout. 
Characters. — Face smooth. Palpus in c rather short, in 9 greatly elongate, second joint 
smooth-scaled, third joint in cf quite small, in Q extremely long. Tongue slight. Antenna in c bipec- 
tinate with moderate branches, in Q dentate, ciliate. Hindtibia in cf greatly dilated, with strong 
hair-pencil, in both sexes with all spurs. Abdomen not crested. Frenulum in c arising before basal 
expansion, in Q obsolete. Forewing with costa straight to near apex, then arched, apex squared, 
termen strongly ventricose, waved or subcrenulate, becoming very oblique, tornus moderate, cell less 
than one-half, DC incurved, very oblique posteriorly, SC! from cell, anastomosing strongly with C, 
SC? normal, anastomosing with SC!, Rl about connate, R? from above middle of DC, M! approximated 
to R?; hindwing with apex weak, termen waved or subcrenulate, strongly ventricose, bent at R! and 
again at R3, cell rather short, DC? incurved anteriorly, C appressed or anastomosing with SC at a point 
near base, then strongly diverging, SC? short.stalked, R? very characteristic, M! connate or short- 
stalked. 
Early stages unknown. 
'The single species was placed by Warren in TAalera, but has little in common therewith 
excepting the marking of the fringes. Essential differences are the presence of frenulum and of median 
spurs, the long palpus and anastomosis of C of hindwing at a point only. Its actual affinities are 
uncertain.

1) C4oroteras marginata on type label 
2) Antharmostes (;) papilio, nov. sp. — O 9, 4o mm. Nearly of the size, shape and structure of »a gija(a, Warren, yj with termen 
of forewing somewhat more excised below apex, more sharply angled at R?, c? with termen of forewing almost smooth; tail of hindwing well developed; 
Cf antennal pectinations much longer than in the allies; palpus rather sherter (in both sexes only about as long as diameter of eye). Face dark red. mixed 
with white beneath ; vertex and shaft of antenna brown-red, occiput green. I horax green, paler beneath. Abdomen dorsally pale reddish, the small crests 
slightly deeper-coloured. Wings bright bluish green, with slightly darker green elongate discal marks, and with broad, pale brown-reddish borders, which 
are irregularly mottled and strigulated with darker brown-red and purplish : that on forewing about 5 mm. in width, limited anteriorly by R? excepting a 
small projection across that vein at some distance from termen, proximal edge formed by a. dark line which bends towards termen between R* and M!: 
that of hindwing slightly narrower, but reaching to costa, its proximal edge approaching termen between R?and Mt, thence somewhat dentate, and finally 
running very narrowly along inner margin almost to base ; both wings with a fine dark terminal line, that of hindwing thickened and brightened with dark 
red between the veins and accompanied by a rather large dark spot at the base of the tail. Under surface much paler, forewing with a broad, cloudy purple- 
fuscous submarginal band from R! to tornus, hindwing with faint traces of the marginal band of upperside. Magila, German E. Africa, May roth, 1898, 
type (Q) in coll. Brit. Mus. ; Victoria Nyanza, c (much worn , co-type in coll. Brit. V us. In the 2 example SC? of the hindwing is (probably exceptionally) 
connate instead of stalked.,
