 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. 



iS 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 oblique 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 ochraceous discocellular spot. Expanse of wings 

 1 inch 7 lines, $ I inch 5 lines. 



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



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

 surface.
