C. semicincta Bmps. (10 e). One of the largest species; brownish black with a blue sheen, collar 
yellow a yellow black divided spot on the first abdominal segment and a brown ring on the 5 th abdominal 
segment, transparent spots of the wings very large and numerous, so that they almost take up the entire 
surface of the wing. Tenasserim, Malacca, Borneo; discovered by Niceville. 
C. transitiva Wkr. (= intermissa Wkr) (lOe). Smaller than the former, crown, forehead, collar, a pair 
of spots on the first and a ring on the 5 th abdominal segment whitish yellow. Forewings with five large and 
sometimes with more small, hindwings with two transparent spots; the spot beneath the forewing cell is in 
typical specimens bean shaped. — In the form basalis Wkr. from Sumatra it is squarer in shape. Malacca, 
Sumatra and Borneo. 
C. kuehni Rothsch. Somewhat smaller than imaon, quite black, forewings with an immense transparent 
spot beneath the cell, which reaches to the outer margin, a large spot in the cell and a few beyond it; hind- 
wings transparent yellow with a black border. Taam Island, westward from the Keys, discovered by H. Kuhn in July. 
C. hyalina Moore (= volans Swinh.). Head and body black, forehead white, abdomen with five orange 
bands and a blue shining end. Forewings entirely transparent with darker veins and borders, which are 
broadest at the apex and in the centre of the ease. Hindwings transparent, yellowish at the base; margin 
black. North India, Sikkim to Buriqah and Assam. 
C. macgregori W. Schultze (10 d). Thorax and body blackish brown, slightly marked with yellow. 
Back of abdomen with fine yellow transverse spots on the segments. The glass spots large and clear, as shown 
in our figure most peculiarly arranged, as we only find in some Syntomis fenestrata from the same locality, 
which however has a broad orange banded abdomen. From the Philippines. 
4. Genus: Streptoplilebia Bmps. 
Of this extraordinary Genus two species are known, both from the Indian archipeligo. They are 
graceful moths with slender bodies, finely feathered antennae in the cf, broad triangular forewings and small 
oval hindwings. The genus is immediately recognizable on account of the extremely peculiar construction of 
the neuration; the upper radial of the forewings running in a curve through the disc and ending not in the 
outer margin, but in the last subcostal nervure, so that a long space is formed. Further in the cf the submedian 
is strongly bent, because the media bears a fur like cushion and the submedian has to run round the lower 
margin of this. Nothing is known of the life history of these extraordinary insects. 
S. obliquistria Bmps. (9f). From Kina-Balu Borneo, has fine black borders to the wings and parellel 
streaks running through the forewings which in the cf arise from the androconia cushion and terminate in 
the apex, and which broaden to a discal spot in the ?. 
S. albipuncta limps. (9 f). From Palawan is very like the former species, but has broader dark margins 
and the oblique streak from the base of the forewings to the forewings to the outer margin is interrupted 
and runs less regular. The neuration is also not quite the same as that of the former species, Hampson 
therefore founded the Genus Talycoptera for this species. 
5. Genus: Triclmeta Swinh. 
The 20 species belonging to this Genus generally shew such a distribution of the spots, that a. very 
large discal spot is either isolated, or is accompanied by a number of smaller spots; only‘one species from 
Cambodia is sharply divided from the mostly dark steel blue Trichaeta on account of its orange yellow ground 
color, and a few others form a transition to true Syntomis through the formation of numerous transparent 
spots. In the forewings the submedian runs close to the rear margin, the lower median nervure branches 
directly behind the centre ol the cell, the middle just at the end of the cell; the upper median nervure is 
stalked with the lower radial. Tongue is present, palpi short, eyes large, antennae sligthly thickened beyond 
the middle. The moths fly in the sunshine and the blue of their ground colour has a brilliant sheen in the 
sunlight. The Genus is almost entirely Malayan, one species inhabits Africa and this structurally does not 
thorougly agree with the others. 
T. tigrina Wkr. (10 e). Uniform orange yellow with darker veins and darker borders to the hind¬ 
wings. In the centre of the submedian space a dark streak. Cambodia; in general appearance it resembles 
the Synt. elivesi Rothsch. which also inhabits hither India. 
T. diplaga Bmps. (lOf). Black, wings with a slight purplish, abdomen with slight greenish sheen. On 
each forewing a full-moon shaped pale yellow area and near the base a. pale spot. Penang, discovered by 
Pinwill; type in the British Museum,
