The female of this species is not the insect described by Meyrick as such 
(loc. cit., 1910); it is much larger, and differs entirely from the female of 
allied H. mermerodes Meyrick by wing shape. At present two female 
specimens, one in the present lot and one in the collection of the Berlin 
Museum, are known to the author; the former specimen may be described 
as follows. 
$ 39 mm (neallotype). Head ferruginous, suffused with dark brown. 
Palpus bright orange-ochreous, darker towards apex. Thorax deep 
ferruginous- brown with blue shine in certain lights. Abdomen pale 
ochreous, brighter posteriorly. Fore wing with costa strongly arched to 
before middle, deeply and abruptly emarginate posteriorly, beyond emar- 
gination angularly projecting before middle, apex considerably projecting, 
rounded and slightly falcate, termen sinuate above, broadly rounded and 
projecting beneath. Deep ferruginous- brown with bluish-leaden gloss; 
some dull ferruginous-purple, irregular, transverse striae on basal half 
of costa, largest stria beyond 2 / 5 , sinuate, outwardly oblique, ending in a 
small elongate-triangular strigula on upper fourth of disc; costal edge dull 
ferruginous along excavation; some three undulate, slightly outwardly 
oblique purple strigulae, first parallel to termen, running from apex to 
tornus, preceded by two shorter strigulae before upper half of termen, 
all three strigulae connected with each other by an oblique transverse 
strigula of the same colour in upper third of disc ; a crescent short streak 
beyond these strigulae on upper half of termen, dark purplish-brown. 
Cilia dark ferruginous (incomplete). Hind wing bright yellow-orange, 
suffused deep orange towards apex, cilia pale ochreous with ferruginous 
basal half. 
Eighth segment (fig. 223a) in female sclerotized throughout. Ostium 
broad. Colliculum, a strong, long funnel-shaped tube, obliquely truncate
