B TERACOLVS. 



the back from the paler green of the under parts. The pupa is compressed and has 

 the wing-cases produced into a keel like that of Terias. It is suspended in the same 

 manner by the tail, and a moderately long band. The colour is some shade of dingy 

 brown or dirty green. The butterfly lays a number of eggs on the same plant, so a 

 great number of small larva are generally to be got from one small branch."

Male. — Similar to T. calais, and intermediate between that species and T. aviatus. 

 Brighter than T. calais in tint, with the black spot above the sub-median nervure 

 very boldly indicated, but the small row of spots near the apex of the primaries nearly 

 obsolete, as in T. amaius. Expanse 1*6 incli. 



Female. — White or lemon-yellow, resembling the female of T. amafus, but easily 

 distinguished by the faintly indicated row of dusky spots on the secondaries, which are 

 separated from the black border of the hind margin by a broad intervening band of 

 white. Expanse 17 inch. 



Habitat. — Madagascar {fi/pes in Mus. P. Croiohy); South Madagascar [Last; 

 Mus.H. Grose Smilh); East and West Coasts (Mabille, I.e.); Mouroundava, South- 

 West Madagascar {Mus. liot/i.^child). 



South-East Africa. — Zambesi (3Ius. Brit.). Pungwe River [Mus. Cecil Barker). 

 Beira (Guy Marshall, P. Z. S. 1897, p. 9). Delagoa Bay (Guy Marshall, I.e.). 



A male and two i'emales of this species (one being of the yellow form) are in 

 Mr. Philip Crowley's collection, and I have seen five specimens representing both sexes 

 from Moui'oundava in the collection of the Hon. Walter Rothschild. Several examples, 

 comprising both the white and yellow forms of the female, are in Mr. H. Grose Smith's 

 collection, obtained by Mr. Last. Three specimens, two males and a white female, 

 are in Mr. Cecil Barker's collection from the Pungwe River, and I also refer to this 

 species an example in the British ^Museum, said to have been procured on the Zambesi,
