SYNTOMIS. By Dr. A. Skitz. 89 



recognisable by the white spots on the forewing being generally much smaller; the large spot on the hind- 

 wing is also reduced in size, and its margins are irregular. The tip of the antenna generally white, but 

 sometimes black, this being the case in ah. taurica Hamps., where the spots are also still more reduced. Hyria. taitrica. 



S. bactriana Ersch. (9 c). Very similar to the two preceding species, especially mestralii, but easily badrUnai. 

 recognised by the large, somewhat rounded, slightly yellowish spot on the hindwing which is situated 

 exactly before the anal angle and far distant from the apex of the wing. The wings of the $ are fully 

 developed. Prom Turkestan. 



S. maracandina Ersch. (9 c). Resembles bactriana, the wings of the $ being also fully developed, '""''"cau- 

 but the wings have a strong metallic sheen with a slight violet tinge, all white spots smaller, that below 

 the cell often comma-shaped, the spot on the hindwing small, round, and close to the base. Specimens 

 with especially small spots are designated ab. cocandina Ersch. Turkestan. eocandina. 



S. caspia Standf. (9 d). Very similar tu tiie preceding species, and probably only a form of it. Fore- caspia. 

 wing almost exactly as in maracandina, only the white spot below the cell is generally larger than the 

 others, and pear-shaped. The spot on the hindwing is also large, being square with rounded corners; 

 it is situated so close to the anal margin that the latter is reduced to a black line. Southern Russia 

 and Armenia and the neighbouring Turkestan. 



S. sintenisi Stgr. (9 d). Much smaller than the preceding species, all spots bright yellow on a back- sintenisi. 

 ground with a strong blue gloss. The hindwing may bear smaller or larger transparent yellowish spots. 

 Central and Eastern Asia, as far as North China. 



S. fortune! Orza (9 d). All spots of the forewing large, oval in basi-distal direction. The hindwing fortunei. 

 entirely yellowish hyaline, only the apex and distal margin blue-black, the marginal band being produced 

 into a tooth directed basad. Japan. The 3'(? very common in August; the $$, which are sluggish and 

 much smaller, rarer. — In specimens from Hokkaido the two s}iots situated below the cell of the forewing 

 sometimes merge together to form a long streak. In ab. erebina Butlr., on the other hand, the spots are erebina. 

 reduced. 



S. cingulata Weber (= anetta Builr.) (9 d). Smaller, rather duller black-brown, without distinct eingulata. 

 metallic gloss, the spots on the forewing very elongated, only the one near the base very small. On the 

 hindwing the hyaline spot occupies the whole anal half. Central and Eastern China, extending in South 

 China onto indo-Australian territory. 



S. cyssea Stall (= collaris F., schoenherri Bdv., caprea Prittw.) (9 e). Similar to the preceding, cyssea. 

 darker, with a stronger metallic gloss, frons and a thin collar (not visible on the plate) as well as the 

 first and fifth abdominal segments bright yellow. Spots on the forewing much smaller than in the preced- 

 ing, the two spots on the hindwing far apart, the anal one being generally larger. Kashmir, but also 

 distributed over the whole of Anterior India, as far as Ceylon, occurring there in large-spotted forms, 

 e. g. cysseoides Btlr. On high-roads, especially on the winding roads leading up the mountains, singly, 

 but not rare. 



S. persica Koll. (9 f). Abdomen with several orange-yellow bands, thorax black. Forewing with persica. 

 large, longitudinal hyaline spots, hindwing quite glassy, with narrow black margin. Persia. 



S. dichotoma Leecli (9 e). One of the largest and finest Syntomis of this region. Abdomen with dichotoma. 

 4 bright yellow rings; the first behind the thorax broad, the second and third narrow, and the fourth 

 on the fifth segment broad. The Iwaline spots on the forewing are often confluent, but in typical speci- 

 mens the two glassy spots below the cell of the forewing are separated b}^ a black bar, which goes from 

 the middle of the cell to the middle of the inner margin. In ab. concurrens Leecli this bar is absent, concunens. 

 so that the forewing presents an almost uniformly hyaline surface. In Western China and Tibet. 



S. formosae Butlr. (= emma Butlr.) (9 e). Size and wing-markings almost as in fortunei, only the fonnosae. 

 ground-colour darker; but at once recognisable by the yellow-spotted thorax, and by all the segments of 

 the abdomen bearing yellow rings. In Central China (Fu-chow), also in Southern China, Formosa and 

 parts of India. Seems to be rai'e on Palearctic territory. 



S. perixanthia Hamps. (9f). Very similar to dichotoma, but the thorax strongly spotted with light P*".'; • 

 yellow, and the abdomen having 7 pale yellow rings instead of 4 orange-yellow ones, these rings being 

 partially shghtly interrupted by a dark dorsal line. In Western China, also in Formosa. — The form 

 persimilis Leech is distinguished from true perixanthia by the black instead of yellow tegulae. From Ni-tu. persimilis. 



S. masoni Moore (= davidi Pouj.). This species stands in the same relation to perixanthia as masoni. 

 concurrens to dichotoma; the marking of the body consisting of conspicuous yellow rings and spots is almost 

 the same. But the wings present an almost uniformly hyaline surface, owing to the absence of the black 

 bars. Western China, Tibet; also in Further India.
