a brightening behind it. No darkening below the costal margin. The spot behind the cell is narrow between 
veins 5 and 6, projecting distally above it as far as the parting of veins 7 and 8. Close behind begins the 
dark submarginal band extending between veins 6 and 3. A light space between the two dark areas between 
veins 4 and 6 is narrow between 6 and 7 and expands again at the apex. Hindwing red-brown, not striated 
dark. $ 120—145 mm. Celebes, Tonkin. 
X. d'Urvillei H.-Schdjf. (= eucalypti H.-Schdff.) (98 a). Thorax light red-brown on the sides, abdomen d'ZJrvillei. 
of <$ blackish with light segmental margins, dark red-brown in the $. Forewing dark red-brown, also violettish- 
brown, with black striae which are more or less radially fused especially in the distal area. A broad white band 
from the base of the wing to below the base of vein 2, and a similar one from before the cell-end to the 
apex. Both are very variably distinct and interrupted by a black longitudinal blotch. Hindwing red-brown 
with black reticulate lines. An aberrative $ (97 d) has not any white at all on the forewing, the black striation 
forms long radial blotches. Abdomen and hindwing, however, lighter red-brown without dark reticulate lines. 
120—180 mm. New South Wales. — aragasii Fldr. is presumably only a greyer $ of d’Urvillei, without any other angasii. 
difference on the body and forewing but that another row of round black spots is traceable below the 
white apical stripe, extending to the white stripe coming from the base. Hindwing also greyer than in 
d’Urvillei and with a similar exterior row of spots as on the forewing. $ 170 mm. Adelaide. 
X. leucomochla Trnr. Thorax laterally white with blackish-brown scales. Abdomen whitish with leucomoch- 
dark brown segments. Forewing dark brown with somewhat white brightenings. A broad white streak from 
the base to the centre of the wing. From there indistinct white streaks to the apex, interrupted by dark 
brown striation. Hindwing dark brownish grey, lighter whitish at the apex and anal angle. J 120 mm. 
West Australia. 
X. leuconotus Wkr. (99 d <J), from Cashmir to Ceylon and the Sunda Is., has already been dealt with leuconotus. 
in Vol. II, p. 418 and figured (the $) on pi. 53 a. According to Hotjlbert, persona Le Guill. is an older name 
for it. According to Snellen, however, persona is a synonym to strix. We cannot decide whose opinion 
is correct, for which reason we keep to the old name leuconotus. 
X. fuscipars Hmps. Thorax dark brown with grey hair. Abdomen blackish-brown. Forewing dark red- fuscipars. 
brown at the costal margin, more or less densely white-scaled above the inner margin. Black spots at the 
inner margin itself. Hindwing paler red-brown, a large triangular white spot with black recticulate lines from 
the anal angle to vein 4. U 40 mm. Sikkim. 
X. strix Or. (= signata Wkr. , bubo Btlr.) (97 b). Body of U blackish-brown. Forewing pale grey, strix. 
sometimes more brownish, densely striated dark. One larger spot each at the costal margin at the base, at 
% and at %, besides many small ones. A spot below the base of vein 2 mostly present, a large one behind 
the cell, a subapical spot at the distal margin of a variable size. Hindwing blackish in the basal area, the 
rest brown with dark reticulate lines. 75—130 mm. mesothorax and the ground-colour of the forewing 
yellowish-white. The spots at the costal margin relatively larger and connected with the spot below vein 2 by 
a broad brown irregular band, so that it shows great resemblance to leuconotus. A variable number of round 
black spots before the margin. Hindwing dark brown, distal margin broadly lighter with dark reticulate lines. 
The dark marginal spots are more distinct on both wings than in the <$. $ 105—220 mm. Sikkim, Tonkin, 
Borneo, Java, Celebes, Philippines, Moluccas, New Guinea. According to Holtlbert, the names granulata Gn. 
and tigrata Gn. not mentioned elsewhere are synonymous to strix. signata and bubo, however, he considers 
to be distantly separated species. — nebulosus Don., the name of a “ species” recurring in all books again 
and again, seems to me to be founded upon a damaged $ of strix. Moreover, it is almost certain that, 
judging from the size stated (19 cm) and the white thorax, leucoloplius Guer. is a $ of strix. The dingy 
white larva, of a finger’s length, lives in Celebes in the wood of Agati grandiflora. — jonnosicola Strd., a 
name only conditionally given by the author himself, denotes a from Formosa, which may occur anywhere 
since the U varies considerably in the intensity of the spotting and the extent of the striation. 
X. anceps Sn. Mesothorax and abdomen yellowish-white, the rest black. Forewing brownish-white anceps. 
with black striae. The base at the costal margin is black; besides, a spot at *4 of the inner margin and 
an elongate spot before the distal margin and the dots at the costal margin are black. The three large spots 
are somewhat fused. Hindwing coloured like the forewing, with black striae and a narrow dark median band. 
$ 62 mm. Java. 
X. bosschae Heyl. Thorax red-brown with a white centre. Abdomen light red-brown with a black bosschae. 
median and lateral line. Forewing yellowish-brown, grey above vein 10, coarsely dusted black. The space 
between veins 8 and 9 is white in front, brown behind. A black longitudinal streak above vein 7 is edged 
with white. Below it another similar stripe. Some small black transverse streaks between veins 3'—6. From 
the base a, black longitudinal streak extends along the first inner-marginal vein and goes vertically to vein 2, 
then before the distal margin upwards to vein 5. All that is without this line is silvery white with a few black 
striae. Some black longitudinal streaks edged with white are at the cross-vein. Hindwing brownish-yellow, 
densely dusted with black. 78—87 mm. Borneo.
