23G Mr. H. Eltringham's Monograph of the 



An apical and hind-marginal black border about 3 mm. wide. 

 At and beyond end of cell there extends from costa a more or 

 less wedge-shaped black mark, its narrower and lower portion 

 being connected with the hind-marginal black, thus enclosing a 

 snbapical patch which may be of the ground-colour or paler. 

 There is sometimes a rather large black spot in 2 close to 

 median and a smaller one below it, and rather further from 

 margin in lb. 



H.-w. may show traces of the spots of underside. Base 

 slightly blackened, hind margin with a black border 2 to 3 mm. 

 wide, the inner edge of which may be nearly parallel to hind 

 margin or it may be somewhat angulated at 3, thus giving 

 the central pale patch a slightly quadrate appearance. 



Underside f.-w. like the upper but paler and with the black 

 of base and cell reduced to a spot in cell. The subapical patch 

 paler than the groutid-coloiir. The apex and hind margin 

 have a .series of triangular reddish-yellow spots. 



H.-w. pale ochreous with a black or very dark brown hind- 

 marginal border bearing triangular reddish marginal spots, the 

 apex of each being produced into a deep black ray, which does 

 not however extend beyond the black border. Numerous email 

 black .spots usually as follows : — One in 8 against precostal, two^ 

 in 7, sometimes one in 6, a streak on discocellulars, and a dot at 

 base of 4 (there is apparently never a spot in 3), one at base of 2,. 

 two in cell, and two in Ic, lb, and la. Some irregular 

 black at base of nervui-es and sometimes a few basal red marks. 



Head black with a pale mark behind each eye, and two reddish 

 tufts on the collar. Thorax black. Abdomen black above with 

 orange lateral and whitish dorsal spots. Claws unequal. 



9 resembles (J, but ground-colour slightly duller, or in some 

 cases much paler. 



A. acerata ncerata. PI. YI, f. 13 (larva). 



Differs from acerata vinidia in having a slightly paler ground- 

 colour, and in the fact that the black wedge-shaped mark in 

 f.-w. is not connected at its lower end with the hind-marginal 

 black, so that the subapical patch is continuovis with the ground- 

 colour. 



f. tenella. 



This is an extreme eastern form of the species. It is 

 characterised by having a much paler ground-colour. The 

 black margins are slightly narrower than in the western forms, 

 and marginal spots are usually visible on the upperside. 

 Scarcely any spots are visible on the h.-w. upperside.
