26 HETEROCERA. 
6. Aristotelia pyrodercia, sp. n. . 7 . 
Antennae delicately annulated with black and white. Palpi yellowish white, the median joint twice 
annulated with brassy brown; terminal joint longer than the median, with three blackish annulations, 
widening in succession from the base. Head pale buff-brown. Thorax pale buff-brown, with a rather 
shining steel-brown median streak. Forewings yellowish brown, crossed by oblique whitish streaks 
mixed with shining steel-like metallic scales, some minute blackish scales intermixed along their 
margins ; a slender steely line, commencing at the base of the costa, crosses the fold obliquely outward 
to the dorsum, beyond it is a broader whitish costal streak, also crossing the fold obliquely outward, 
but scarcely reaching the dorsum; a third steely streak, from the costa before the middle, tending 
obliquely outward, is enlarged at the lower end of the cell and reverts to the middle of the dorsum, it 
is preceded by a pale plical spot margined on its inner side by black scales ; beyond this, about the 
middle of the costa, an oblique whitish streak tends outward to the end of the cell where it meets 
a more conspicuous white streak inverted from the costal cilia, both mixed with pale steel and blackish 
scales; beyond the last white costal streak the costal cilia are greyish fuscous, with two inverted 
whitish streaklets at their base, a third shining white streak following the termen at the base of the 
whitish cilia through which run two dark shade-lines terminating before the tornus where a yellowish 
white line in the tornal cilia interrupts them ; near the base of this is a luminous steely spot, with some 
minute black scales along the margin. vp. al.12 mm. Hindwings and cilia tawny greyish. Abdomen 
brownish cinereous. Legs whitish, banded externally on the tibiae and tarsi with brownish fuscous.

6000 ft., VIII. (1. H. Smith). Three specimens. 
This species differs from hieroglyphica Wlsm. in the more olivaceous brownish- 
ochreous ground-colour which lacks the blackish shades, in the basal half especially, 
and the silvery markings connected with the outer streaks are more conspicuous. 
7. Aristotelia sarcodes,.sp.n. (Tab. I. fig. 23.) 
Antennae black, with elongate white spots along the upper side; basal joint white, with a black line beneath 
and a spot above. Palpi white, median joint -with two black bands not reaching the upper surface ; 
terminal joint with four black bands of which the outer two only complete its circumference. Head 
pale brownish, mixed with whitish scales. Thorax pale rust-brown, with some silvery median scales. 
Forewings yellowish brown, or light rust-brown, with white and shining silvery costal and dorsal 
streaks, more or less confluent on the wing-middle, and with two, noticeable, rosy flesh-coloured, short 
length-streaks, one at the upper edge of the outer end of the cell, the other wider, beyond the end 
of the cell; there is a rather oblique white costal streak, at one-fifth, with a few black scales along 
its inner edge, its outer half touched with shining silvery ; this meets the apex of a short silvery dorsal 
streak, at’ about one-fourth, and is followed by a second, shorter, silvery and white costal streak to 
which there is no corresponding dorsal one ; a third, silvery and white costal streak, is scarcely beyond 
the middle, and is interrupted by the first rosy flesh-coloured streak before joining a longer silvery 
oblique streak from the middle of the dorsum; beyond this again are four short white costal streaks 
before the apex, the first two sometimes confluent, and both tipped with silvery, the second rosy 
flesh-coloured length-streak separating them from a long silvery dorsal streak arising obliquely outward 
from near the tornus; there are also a few silvery scales on the termen below the outer white costal 
streak which occupies the apex and apical cilia; terminal cilia whitish, touched with brown ‘on the 
middle of the termen and at the tornus. Exp.al.10 mm. Hindwings dark slaty grey, with a strong 
rosy iridescence; cilia brownish grey; ¢ with dull ochreous subcostal hair-pencil. Abdomen grey. 
Legs white, hind tibiae and tarsi with black bands across their outer sides.
