246 Mr. H. Eltringliam's Monograph of the 



difference being the absence of the spot on discocellulars 

 in h.-w. 



Such an example of the rcntura form as is described 

 above is really not quite typical, as Hewitson's type is in 

 fact more like an intermediate between tcrpsichore and 

 vcnUira, the red on the h.-w. underside being less developed 

 than in the more extreme forms. 



A. terpsiclwre orlirasccnn, subsp. 



(^. Expanse about 42 mm. Wings pale creamy white. F.-w. 

 with a slight dusky suffusion at base, a dusky powdering along 

 costa, about 1 mm. wide to jiist beyond end of cell, where it 

 becomes very narrow, finally joining an apical l)rownish black 

 patch about 4 mm. wide. At area T) this apical jjatch becomes 

 suddenly narrower and continues along the hind margin as a 

 border about 2 mm. Avide bearing marginal or subniarginal spots 

 of the ground-colour. At end of cell a Idackish, more or less 

 wedge-shaped mark like that in ferpsichore. 



H.-w. blackish at base with a slight indication of the small 

 discal and basal sjiots of the underside, those in 7, and on the 

 discocelluhirs being most distinct. A blackish hind-marginal 

 border about 2 mm. wide bearing large spots of the ground- 

 colour. 



Underside, f.-w. Like the upper but no apical and marginal 

 black. The ends of nerv^ules are however distinctly black. 

 Margin with a fine black line. 



H.-w. as on upperside but without black basal suffusion. 

 A little irregular black at base and a spot in 8 close to precostal. 

 Across the wing at the level of end of cell a double row of small 

 linear black spots formed by two in 7, one in cell and one on 

 discocellulars, two in Ic, lb, and la. In 7, cell, and Ic these 

 spots enclose reddish marks. Hind-marginal border of a com- 

 plicated pattern somewhat resembling that in terpsichore. The 

 ends of nervules are black, and from the extremity of each 

 arises a pair of internervular streaks. Each of these streaks 

 meets one from the next nervule at a point some distance from 

 margin, and the triangle so formed encloses near its apex a 

 reddish mark. This border is only about half as wide in 4 and 

 5 as elsewhere, so that in those areas the ground-colour extends 

 outwards in a characteristic manner, Bometimes there is a spot 

 at base of cell. 



Head and thorax black, abdomen black above with whitish 

 lateral spots and segmental lines.
