20. Genus: Hypocoela Warr. 
Agrees with the preceding genera in the firm texture of the wings, the short antennae and a few 
other characters. Palpus shortish or moderate, the 3rd joint in the $ elongate. Antenna in both sexes pecti¬ 
nate, the branches moderate or rather short in the (J, quite short in the Hindtibia with all spurs. Wing- 
form characteristic: forewing with costa arched distally, apex more or less falcate; hindwing with costal 
margin short, abdominal margin long, distal margin smooth, curved. Exclusively African. 
H. drepana Prouf. Distinguishable by the sti’ongly falcate apex, which recalls a Drepanid. The dark drepana. 
basal patch and reddish central band, on a paler reddish ground-colour, also characteristic. Antennal pec¬ 
tinations in (J about 3 times as long as diameter of shaft. Central Madagascar. 
H. humidaria Sivmh. A variable spec'es, reddish or greenish, the markings much more confused than humidariu. 
in drepana, the apex less acutely produced. Upper-and underside with some coarse grey strigulae. Face red; 
vertex white. The type is reddish, with an ill-defined blackish band. — ab. viridescens nov. is greenish, with viridescens 
the central band only outlined, the costal area of the hindwing reddish. — ab. viridicolor nov. is more uniform viridicolor. 
green except that the strigulated area beyond the middle of forewing is more shot with violet-grey. Madagascar. 
H. subfulva Warr. (3 b). Apex only shghtly falcate, distal margin of forewing faintly concave bet- .suhfulva. 
ween the radial veins. Forewing beneath greenish, mixed with orange-buff, hindwing almost entirely of the 
latter colour; forewing with a blackish subterminal band in posterior part, sometimes fragmentary. Described 
from Nigeria, fairly general from Sierra Leone to the Congo. - - uniformis Warr., from Uganda, is a rather uniformis. 
large $ form with much stronger submarginal bands. As only the type is yet known, it may prove to be a 
mere aberration. 
H. spodozona Prout connects subfulva with humidaria, having more nearly the coloration of the former spodozona. 
but lacking - - like humidaria — the concavity in the termen of fore wing. The central band of dark irroration 
and the white subterminal lunules are distinctive. Underside nearest to that of subf ulva, the subterminal band 
replaced by blackish spots. Central Madagascar. 
H. turpisaria Siuinh. (3 a) ^ about 27 mm, $ larger. Eorewing rather broad, with a rather deep excavation turpisuria. 
behind the apex; dull green, easily fading to yellowish; a dark cell-dot and a curved dark outer line (from the 
1st radial to hindmargin near tornus), beyond which is sometimes a solid dark border. Hindwing largely clouded 
with dark purple-grey, especially anteriorly, and crossed by ill-defined lines of the same colour. Underside 
much clouded, but with the costal region of the forevdng red. Nigeria and Cameroons. — ab. semirufa Druce semimfu. 
has the proximal half of the hindwing above bright orange-red, recalling the following species. 
H. zapluta Prout differs from turpisaria (3 a) in having the greater part of the hindwing, and almost the zaphda. 
whole of the underside, bright orange. Hindwing without lines, a greenish border, about 3 mm in width, from 
the tail to the abdominal margin, extending very narrowly along the latter towards the base. Only known 
from Uganda. 
20. Genus: Autharmostes Warr. 
PerhajDs a group within the genus Gelasma, chiefly distinguished by the better develojied (though still 
generally small) abdominal crests and the more ornate distal margin. Exclusively African. 
A. Abdominal crests small. pectinations very short. Hindwing without a tooth at end of 1st radial. 
A. simplicimargo Profit (3 b) has the simplest pattern, only a costal line and the terminal line of both simpUci- 
wings being red. Abdominal crests vestigial, dull reddish. Hindwing with the tail rather shorter than in most margo 
of the other species. Upper Congo. 
A. interalbicans Warr. (3 b) is the commonest species and differs in the sinuous white, slenderly dark- hiteralbi- 
bordered line at distal margin. Underside paler, the middle of the forewing suffused with reddish; terminal line 
and fringe very dark. Sierra Leone to Congo, the type from the latter country. 
A. mesoleuca Warr. differs from interalbicans in lacking the white terminal line but developing, on the )ncsoleuca. 
other hand, a conspicuous white terminal spot between the 3rd radial and 1st median an both wings. Perhaps, 
however, a mere aberration. Southern Nigeria. 
A. marginata Warr. Variable, perhaps a further development of ^nesoleuca, with the midterminal patches marginata. 
much extended. The distal margins, however, make a slight approach to papilio in shape. — ab. semimarginata semimargi- 
Warr. has the dark terminal line thickened, the pale spots more or less dusted over with fuscous. — ab. fuscimai'go . 
lF«rr. has the dark borders still broader, the central pale spots 3 mm in width. — Sierra Leone to the Congo; 
Uganda.
