L. subusta Warr. (= ustata Swinh.) (20 c). In colouring, etc. slightly reminiscent of Nobilia, but 
smaller; impossible to confuse with any other known species. North India, Burma and Formosa; type subusta 
from Sikkim, of ustata from the Khasis, where it is very common, though the $ is very retiring. 
28. Genus: \ obilia Wahk. 
Palpus shortish-moderate. Antenna of $ with fascicles of long fine cilia. Hindtibia of $ short, with 
long hair-pencil, hindtarsus not shortened, hairy, at least its 1st joint; of $ with all spurs. Forewing with 
areole double, 2nd subcostal stalked with 3rd—5th, 2nd radial arising much before middle of discocellulars. 
Hindwing with 2nd subcostal from about the apex of the cell, or very shortly stalked with 1st radial. A small 
genus, belonging chiefly to India and Malaysia and entirely confined to the Indo-Austrahan Region. See Novi- 
tat.es Zoologicae, Vol. 38, p. 1—6. 
N. obliterata Warr. (20 c) is the simplest species in markings, conserving a normal (though indistinct) 
postmedian and on the hindwing a small black cell-dot. Borneo (type), Perak and Sumatra. 
N. cupreata Pagenst. (= nebulosa Warr.) (20 c). Hindwing still less bent at 3rd radial than in obliterata-, 
the pale costal streak of all the succeeding species indicated; distal area, and on the forewing the proximal 
also, suffused with a slightly deeper, more coppery shade. Amboina; I only know the two types, both $. 
N. avellanea Prout (20 c). Formerly supposed to be a form of turbata, but distinguishable by the tone 
of colour and nearly always by the postmedian of the forewing, which forms an acute angle at the 2nd median. 
The genitalia show it to be a good species. N. India (the type from Cherrapunji), Burma, Tonkin. Malaya, 
Sumatra and Borneo. 
N. turbata Walk. ( strigularia Snell.) (20 c), the type of the genus, has the dark parts considerably 
darker than in avellanea and some other appreciable differences. Described from Sarawak, it is also known 
from E. Pegu, Tenasserim, Malaysia and some of the Philippines, at least Mindanao and Mindoro. There may 
be differentiable races. 
N. erotica Prout is larger, more cinnamon than most turbata , though more dark-mixed than avellanea-, 
forewing with the postmedian almost as acutely angled as in the latter; hindwing with termen apparently 
slightly more crenulate than in turbata, terminal area between the radials more clouded with the ground¬ 
colour. Plate of 8th sternite less deeply emarginate at posterior edge than in turbata ; aedoeagus much stouter 
than in the rest of the Nobilia. Celebes. 
N. fastigata sp. n. (20 c). Considerably smaller (40 mm) and much paler, particularly on the under¬ 
side, which has none of the orange colour of that of the turbata group, though the hindwing and (especially) 
the costal and distal parts of the forewing have some fleshy suffusion. Hindtibia pale, much more strongly dilated 
than in erotica. In the markings of the forewing the following distinctions are appreciable: costal edge, though 
narrowly, more or less strongly dark-marked; distal edge of the reddish posterior patch more curved, narrow¬ 
ing the pale ground-colour at hindmargin; postmedian line more produced at 2nd median vein than in most 
erotica, more sinuous between this point and the 3rd radial. Paloe, W. Celebes, a few collected with many 
erotica (J. P. A. Kalis). Type in the Tring Museum, from Gunong Rangkoenau, 900 feet. 
N. aphrodite Prout (20 d). Termen of hindwing with a well-defined central tooth; otherwise in some of 
its forms scarcely distinguishable from turbata ; pale parts nearly always with a more decided tinge of brown; 
forewing with the cell-spot and often the postmedian line more as in avellanea; terminal area as in avellanea 
or even paler. The $ is more cinnamon than the <$, occasionally even much like avellanea. New Guinea, the 
type from Upper Aroa River; also from Ron, the d’Entrecasteaux, Danrpier and Vulcan Islands. — rooki 
subsp. nov. Very similar to a few very strongly marked a. aphrodite, but with the dark outer band of the 
forewing copiously (though very finely) strigulated with the pale ground-colour, whereas in the similar a. aphro¬ 
dite it is solid. Rook Island (Bismarcks), apparently not variable except sexually, the $$ about as deeply 
coloured as average Uc? of the name-typical race. Also a 9 from Talasea. New Britain, in January. Type q 
in the Tring Museum. 
N. molybdina sp. n. (20 d). Much darker, with more slaty or plumbeous tone (sometimes almost violet); 
forewing with costal edge strongly darkened, except distally, base somewhat suffused, ante- 
median line less oblique, postmedian with the angle at 2nd median vein less acute, usually quite rounded off; 
hindwing less variegated. The genitalia fully confirm its right to rank as a species. British New Guinea and 
New Hannover, the type series in the Tring Museum, from the Hydrographer Mountains. - tombarensis subsp. 
nov. is a trifle larger and reverts towards the colouring of aphrodite, so that at first sight it might be possible
