S. luteifascia Hmps. (lOi) comes likewise from Assam (Naga Hills). Both wings have the hyaline spots 
extraordinarily enlarged, so that they touch one another, without actually uniting. Abdomen brightly ringed 
with orange, the rings more regular than in flavifrons; fringe of forewing not white below apex. 
S. berinda Moore (lOh). The abdomen resembles that of the preceding species, but has the rings more 
conspicuously orange; on the forewings the spots resemble those of flavifrons, also in the white fringe below 
the apex of the forewing; but on the hindwings the two hyaline spots are somewhat tinged with orange and 
occasionally united. Tenasserim and the Port of Moulmein. 
S. polymita Sparrm. (= thelebus F.) (lOi) was taken by me in great numbers on the flowers growing 
along the cemetery-walls in Happy Valley near Hongkong, together with Synt. grotei and Tryganophora argyrospila 
Wkr., a Zygaenid which it outwardly resembles. Abdomen very conspicuously ringed with orange-red, thorax 
similarly spotted. As is seen in the figure, the basal hyaline spots on the forewing are nearly touching, being 
only separated by a dark cross-bar in the submedian interspace. This patch varies greatly, from being heavy 
and broad, to a slight comma-shaped streak. When it. is entirely absent, as is rarely the case, it greatly 
alters the general appearance: = ab. sepulcrorum nom. nov. (= ab. 1. Hmps.). Southern China to Tonkin. — 
fenestrata Drury (9f) closely resembles polymita in colouring and abdominal markings, but both wings have 
the spots very elongate and, as is the case with most Philippine Syntomids, distinctly drawn ont in the direction 
from base to apex. Philippines. 
S. perixanthia Hmps. (Vol. 11, pi. 9 f) is largely Palaearctic and, for that reason, described in Vol. 2. 
Type from Formosa; it greatly resembles the preceding forms, but the abdominal rings are paler yellow and 
narrower: ab. persimilis Leech has the patagia black instead of orange. — sinensis B’othsch., lately described 
from Palaearctic Western China, differs from typical perixanthia in the larger size and yellow instead of orange 
abdominal markings. 
S. mnirheadi Fldr. (Vol. 2, pi. 9g) has the hyaline spots in the submedian interspace united like in 
polymita ab. sepulcrorum , but may be distinguished by having the first four abdominal rings interrupted by 
black on the back. — In ab. aucta Leech the hyaline spot fills the cell as far as its apex; above rib 5 no 
spot. From Hongkong northward into Palaearctic China; rather scarce, and difficult to distinguish among the 
great numbers of polymita with which it associates. 
S. divisa Wkr. (9d) replaces in the North of Farther India dichotoma Leech (Vol. 2, pi. 9e) from China 
which it closely resembles in size and appearance. Like this it has four broad, golden yellow abdominal rings, 
but the last abdominal third is black without any rings. From dichotoma easy to distinguish by the yellow- 
marked thorax and the white frons. The hyaline spots may greatly increase and even unite into large patches, 
as in dichotoma ab. concurrens (vol. 2, pi. 9e), = fa. disrupta Moore. As a rule Sikkim specimens have the 
smallest, those from Burma the largest hyaline spots. 
S. serrata Hmps. (lOi) has the abdomen just as prominently ringed with orange as in polymita , but 
several rings are in the middle interrupted, and the last segment is black-blue. The wings are all, except the 
termen at the ends of the veins hyaline, only the forewings have at the end of the cell a dark cross-bar. 
Khasia Hills, Assam. 
S. yunnanensis Rothsch. Black; pectus, frons and spots on tegnlae and shoulders orange; abdomen 
with steel-blue metallic lustre, ringed with orange. Wings translucent yellow, with broadly dark brown termen 
and veins. Forewing with black spot at apex of cell. 21 mm. Upper Yunnan. 
S. newara Moore ( 1 0i) like serrata, but the forewings nearly completely hyaline, slightly yellowish, 
only a small spot at the apex of the cell black, and the apex, inner margin and a marginal spot above the 
anal angle of the forewing blackish-grey. Sikkim, Bhotan. 
S. signata Wkr. (10i) has the 1., 5- and 6 th abdominal segments delicately ringed with yellow, the 
other rings broken up into lateral spots by the black markings of the back. Head and thorax brillant deep 
yellow. Forewings hyaline with black apex, a similar spot crossing the submedian interspace, and a dash 
from apex of cell to termen. Java. 
S. compta Wkr. (10k). Body quite brillant yellow, abdomen basally broadly ringed with bright orange, 
the last 3 segments black-blue. Khasia Hills in Assam. 
S. quadrifascia Hmps. (10 k). Abdomen with only 4 very broad rings. Wings transparent, borders 
dark. Two dashes of black, one from the end, the other from the middle of the cell toward the outer margin. 
From Bernardmyo (Burma), 6000 ft. above the sea. 
S. vitrea Wkr. (= austeni Moore; polyzonata Hmps) (10k) has the body largely brillant yellow, finely 
marked with black. Wings transparent, bordered and streaked with black as in quadrifascia , but much more 
delicately. Northwestern part of Farther India.
