72. Genus: Scaptesyle Wkr. 
Closely allied to the preceding genus, from which it chiefly differs by the two lower radial veins of the 
forewing being petioled. In the venation of the hindwing no difference. 
S. dichotoma Meyr. (16 cl) has white forewings with brown transverse markings being several times dichotoma. 
connected; hindwings and body red-brown; vertex, collar and mesothorax purely white. Queensland, New 
South Wales, Victoria. 
S. aroa B.-Bak. (26 b) is somewhat like the preceding, but larger, with narrower wings and more aroa. 
abundantly marked; head white, palpi brown, thorax white with a brown collar, with a brown median stripe 
and the shoulder-covers bordered inside with brown; abdomen whitish. The white forewings exhibit brown, 
broad basal, antemeclian, median and postmedian and subterminal transverse lines; the 3 former lines are 
connected by a brown-streak on the median; the two distal lines are almost confluent and separated only by 
a row of white spots: the median line is connected with the postmeclian line near the upper cell-angle, the sub- 
terminal line sends forth a pointed tooth to the margin, on the 3rd radial the latter being brown with speckled 
white fringes. The white hindwing shows a brown marginal band being narrowed towards the anal angle. Expanse 
of wings: 34 mm. From the Aroa River. 
S. fovealis Hmps. is in the distinguished by a large, ditch-like depression below the cell of the fore- fovealis. 
wing, containing accumulations of flaky scales. The cell itself is long, narrow and curved, the veins strongly 
curved, both the median veins anastomosing, the upper radial vein rising below the upper cell-angle. The 
costa of the hindwing is very convex, and exhibits below its middle a large, glandular swelling; the veins are 
likewise very much curved, the upper median vein anastomoses with the lower radial, and the upper radial 
with the subcostal vein. Head and collar are golden yellow, thorax and abdomen red-brown, with a purple 
lustre, like the forewings which exhibit a bluish-green lustre at the margins of the yellow areas; an antemedian, 
golden yellow band widened towards the costa; a golden yellow marginal band is broad at the costa, but growing 
much narrower towards the proximal angle; the bordering of the brown area is distally angled on the upper 
radial vein. Hinclwing in the basal area light yellowish, in the marginal half pale purple-brown, in the apical 
half and at the fringes mixed with yellow. Expanse of wings: 16 mm. New Guinea (Port Moresby). 
S. tricolor Wkr. (16 d) has golden yellow wings, the base and costal margin of the forewing being tricolor. 
black, like the marginal third which, however, is filled up by a large, copper-red spot. Hindwing with a black 
apical spot continued to the anal angle as a fine border. Assam, Burma, Philippines, Borneo, Sumatra, Java, 
Celebes. 
S. plumosus Rothsch. Head, antennae, thorax and abdomen black; collar and basal half of the shoulder- plumosus. 
covers golden yellow, anal tuft yellowish-grey. Forewing: base black, the basal two thirds golden yellow, behind 
followed by a dentate black transverse band, the distal third chestnut-red, bordered with black. Hindwing 
golden yellow, apex as far as down to the 1st median black. In the $ the black is much more extensive, the 
chestnut-red colour darker and duller. Length of forewings: 13 x / 2 mm, $ IT 1 /., mm. Kina-balu (North Borneo). 
S. ixias Hmps. (16 d) resembles the preceding, the yellow colour is deeper, the marginal spot orange- ixias. 
red. Nias, Java. 
S. thestias Snell, is likewise similar, but easily discernible by the deep, tooth-like merging of the thesiias. 
yellow colour into the black distal-marginal third on both wings. Head, thorax and abdomen black, collar < 
and shoulders yellow, anal tuft grey. 
S. mirabilis Hmps. (16 d) differs from the preceding by the much more extensive and bright sulphureous mimbilis. 
colour and the reduced black marginal area which is here filled up with vermilion. Borneo. 
S. bicolor Wkr. (= nietneri Fldr.) (16 e) has in the basal half orange-yellow forewings, distally bluish- bicolor. 
black. Body black, collar and shoulder-covers orange-yellow. Ceylon. •— subsp. integra Swinh. is lighter yellow, Integra. 
and the black distal halves are much narrower. From Assam, Borneo, and Pulo Laut. 
S. rothschildi nom. nov. (= bicolor Rothsch. nec Wkr.). Head and antennae black; thorax orange- rothschildi. 
tan-coloured; abdomen dull black. The basal three fifths of the forewing orange-tan-coloured, the distal two 
fifths black. Hindwings orange-tan-coloured, broadly bordered with black. Length of forewings: ll 1 / 2 mm. 
Malayan Peninsula (Padang Rengas). 
S. aurigena Wkr. (= biplaga Fldr.) (16 e) is easily recognized by the broadly blue-margined purple aurigena. 
spots on a golden yellow ground. The whitish hindwings are tinted brownish towards the margin, particularly 
at the apex. Borneo.
