36. Teracolus zoe. 



Anthocharis zoe, Grandidier, Rev. Zool. p. 272 (1867). 



Callosune zoe, Kirby, Syn. Cat. p. 504. n. 51 (1871). 



Madagascar. 



This species seems to me to be closely allied to the preceding ; 

 Kirby, however, refers it to Callosune, whilst he places T. phisadia 

 in the genus Idmais. 



I am pleased to find a typical Idmais described as an Anthocharis 

 by a man who, inasmuch as he worked but little at the Lepidoptera, 

 was obliged, when he did so, to examine into their structure, because 

 it is a confirmation of my own conviction that Idmais does not differ 

 structurally from the group Callosune, hitherto regarded as a distinct 

 genus by many Lepidopterists. 



37. Teracolus protractus, n. sp. 



$ 2 • Wings above rosy salmon-colour, the base, costa of prima- 

 ries, abdominal area of secondaries, and five to seven decreasing spots 

 on the outer border of primaries ashen-grey ; a broad black-brown 

 outer border, paler, and occupying nearly half the wing in the 

 secondaries of the female : wings below sordid pale buff ; primaries 

 with the base of costa and cell sulphur-yellow ; outer border greyish, 

 owing to the semitransparency of the wing ; a black spot at end 

 of cell, and three below median branches, the lowest one bifid ; 

 secondaries with the external area greyish, as in the primaries. 

 Expanse of wings, S 1 inch 8 to 9 lines, $ 1 inch 7 to 9 lines.

38. Teracolus modestus, n. sp. 



c? . Very like T. amata, pale pinky salmon-colour, grey at base ; 

 the outer border broadly black-brown, upon primaries very feebly 

 sinuated internally between the median branches, barely enclosing a 

 spot of the ground-colour on interno-median interspace, and marked 

 by an oblicpie slightly inarched series of three subapical points of the 

 same colour, upon secondaries bordered internally by four minute 

 points of the ground-colour, limited by black dots and surrounded 

 with grey ; costal area black-brown, broader in the male than the 

 female, and on the primaries dusted in front with grey : wings of the 

 male below yellow as in T. amata, with similar markings, but the 

 spots at end of cells very minute and ill-defined : the female, which 

 is paler above than the male, is slightly tinted with grey below ; two 

 or three extremely ill-defined ochreous spots beyond the cell of pri- 

 maries and bounding the usual pale yellow spots of the disk ; fringe 

 feebly pink ; secondaries with a discal series of five ochreous spots, 

 and a pale-centred ocbraceous discocellular spot. Expanse of wings 

 1 inch 7 lines, 5 I inch 5 lines. 



Ceylon (Templeton). d $, type, B.M. 



A white variety of the female occurs, not differing on the under 

 surface.
