c??. Antenna much slenderer and obviously longer in both sexes than in 

 specimens of atropos of the same size ; the middle segments in the ? barely three 

 times as high as long (PI. LX. f. 21, lateral view). Anterior tibia longer than 

 in atropo.<, first segment (PI. LXIV. f 2) slenderer, and, like the other segments, 

 with less spines thau in either atropos or Idckesis ; the lateral apical spines 

 obviously prolonged ; the unmber of spines individually variable as in the other 

 species ; middle tibia as long as the first tarsal segment ; hindtibia equal in length 

 to tarsal segments 1 to 3. 



cJ. The ventral process of the harpe (PI. XXXV. f. 3) almost vertical on the 

 plane of the clas2)er, its broader side nearly horizontal ; the second process triangular 

 as in atrojios, its broader side dorso-ventral (vertical) ; both processes simple or 

 indistinctly notched. Tenth segment represented by PI. XXVI. f. 20. 21. 



?. Aperture of vagina without process, but there is a mesial carina runuiiig 

 jiroximad from the rim of the opening. 



Larva: according to Swinhoe, I'roc. Zool. Soc. Loud. p. 20(1. n. 25 (1885), 

 variable in colour like that of A. lachesis ; those feeding on potato bright canary 

 yellow with violet stripes, those feeding on jasmine. Datura, Colea, and Eri/tlirina 

 green with purfilc strii)es bordered with yellow. Swinhoe does not give a distinctive 

 character between the larvae of lachesis and st;/x. Moore, I.e., figures the larva 

 oisti/.c as green with yellow stripes. Swinhoe may have confounded the larvae of 

 the two species. Further researches are necessary. — Food : Sesamum, J/citura, 

 Solanum, Cocci iiid, Colea, etc.. 



llah. Indd-Malayan Subregion as far north as Japan, eastward to I'eram and 

 Kisser, westward occasionally occurring in Asia Minor ; one specimen received 

 fVoni Bartierton, Transvaal (most likely imported to S.E. Africa on board a ship).
