Description in Seitz

T. cerisyi God. (9d). Closely resembling in colour and pattern the male of Sericinus, being like this spotted with black on a pale yellow ground, the hindwing bearing traces of red near the middle of the costal margin and at the anal angle. Hindwing with only one strongly prominent tooth. Balcan States, Greece and Asia Minor; not so common as polyxena, occurring from April till early June, being still earlier in the southern districts. — The female varies very much ; specimens which are very strongly spotted with black are sold by dealers as ab. obscurior (9d), in albidior (9e) the ground-colour is white, in ochracea (9e) bright yellow, and in pallidior (9d) fallow; in ab. flavomaculata Verity the carmine dots are replaced by dots of honey-colour; all these aberrations occur together with ordinary cerisyi. — caucasica Led.[now species Allancastria caucasica (9e) has in both sexes very large, broad, black costal spots on the forewing, the hindwing being sUghtly and almost evenly scalloped, the middle tooth hardly projecting; in Armenia. — deyrollei Oberth.[ now species Allancastria deyrollei] (9d) has the three teeth before the anal angle of the hindwing prolonged into short tails; in the coast districts of the Black Sea, in the whole of Asia Minor, southward to Syria; extremely common, in some places appealing in enormous numbers. — cretica Reb. (9e) [now species Allancastria cretica] occurs on Crete and some Greek islands; a sparsely marked form in which the three teeth of the hindwing mentioned above are indicated only by black curved lines, the edge of the wing not being distinctly excised. Not so common as the preceding. — Larva yellow, brown or reddish, the tubercles being red; from May till July, on Aristolochia. Pupa dust-colour or yellowish grey, variegated with thin black dashes , especially on the head. — The buttertlies are on the wing on the first warm days of the year at rocky places and the edges of woods. ^[1]
