202 HELIORABDIA; MONOSYNTAXIS. By Dr. M. Draudt. 
C. viridata Wkr. (= strigata Moschl.) (on t. 15 f the palearctic alpina Hmps. has been figured 
by mistake as viridata) is smaller than the figure, with an entirely metallic green costal margin and a broader 
yellow proximal margin; besides it exhibits, like the following, scent-scale stripes on the forewing, which are 
absent in alpina. Thorax black. Sikkim, Assam. 
C. bivitta Wkr. (= disjuncta Moore ) (Vol. II, t. 12 f) has been dealt with in the palearctic part, and 
differs from the preceding essentially by its yellow thorax and much larger size. North West Himalaya, Assam 
and Sikkim. 
C. aurantiaca Hmps. (15 f) is still larger than the preceding and has no scent-scale stripes on the fore¬ 
wings; thorax yellow, shoulder-covers blackish-green, bordered with orange. Assam, Khasia Hills. 
C. wiiemani Hmps. (= taiwana Wil. $, nec <$). By the name of taiwana Wileman has combined 
2 different species. Of the present species only the $ has become known so far. The body is yellow, the palpal 
ends, sides of the forehead, and antennae black. Collar metallic green on a black ground with a yellow margin. 
Legs black and green. Forewing yellow with an ecpially broad, black costal-marginal streak suffused with green; 
a similar oblique band extends from the base of the proximal margin to the distal margin on the middle radial 
vein. Fringes in the apical half black. Hindwings yellow. Expanse of wings: 54 mm. Formosa. 
116. Genus; Hcliorabdla Hmps. 
Palpi shorter than in the preceding and straightly porrect. On the forewing the middle radial is present 
arid rises in common with the lower radial from the lower cell-angle, the upper median vein rising some distance 
before it. On the hindwing the lower radial vein is absent; the middle one rises with the upper median vein 
from the cell-angle. Subcostal and 1st radial are quite coalescent. The genus has been based only of late on 
a species from Formosa. 
H. taiwana Wil. $. Head and thorax light buff, the latter with a bluish-black dorsal spot, abdomen 
buff. Forewing light buff, the costal margin bordered with bluish-black, in the basal two thirds narrowly and 
in the apical third broadly, above the proximal margin a broad, bluish-black stripe; its proximal end pointed 
and bent upwards, but not reaching the base of the wing, the other end rounded before the posterior margin. 
Hindwings light buff, beneath similar to above, but the marking of the forewing without the blue tint. 44 mm. 
Formosa. 
117. Genus: Monosyiitaxis Swinh. 
Likewise allied to the preceding genera and distinguished by short, porrect palpi, the accessory cell 
being absent, the upper radial rising from below the upper cell-angle, the 1st and 2nd subcostal veins rising 
separately from the cell, the other subcostal veins on a joint footstalk; on the hindwing the discocellular is 
present, all the radial veins are unpetioled. 
M. trimaculata Hmps. (15 e) has a bluish-black head and thorax, palpi, forehead, collar, and base of 
shoulder-covers orange like the abdomen, the latter above as far as almost to its end dull bluish-black. The 
bluish-black forewing exhibits 3 oblong, orange spots below the costal margin. Hindwings orange-vellow. 
Borneo (Kina-balu), Java. 
M. affinis Rothsch. is closely allied to the preceding. Head orange, antennae black; thorax steel-green, 
collar and the distal two thirds of the shoulder-covers orange; abdomen dark slate-coloured, the sides of the 3 
last rings orange-yellow. Forewing above the median orange; the basal 2 thirds of the costal margin and the 
wing below the median purple-brown with a steel-green reflection. Hindwings reddish-orange. Length of 
forewings: 22 mm. Malayan Peninsula. 
M. persimilis Rothsch. is very much like Chrysaeglia (?) bipunctata B.-Bak. flying together with 
it ; at first sight recognizable by its combed antennae; forehead black, vertex, collar and shoulder-covers Isabel- 
coloured ; the thorax exhibits small, indistinct, dirty grey spots. Abdomen yellowish-white. Wings larger and the . 
hindwings rounder. The forewing exhibits two dark brown spots, the proximal one being narrow crescent if or m. 
Length of forewings: 21 mm. Mount Goliath, Dutch New Guinea.
