294 Mr. H. Eltringliam's Monogro'ph of flic 



remainder of wing almost devoid of scales, except the median 

 nervure and the basal portions of its branches which have a 

 narrow but very dense lateral clothing of large oclireous scales. 



H.-w. Those areas which on the upperside are black, are 

 here dusky lemon oclireous. The hind-marginal border 

 regularly striated by black nervule ends and rays, the latter 

 reaching the margin. Black spots somewhat variable, but 

 usually as follows; — One at base in 9, one in 8 against precostal, 

 two rather close together in 7, two in cell, the second over the 

 origin of nervule 2. A basal, a subbasal, and a median in Ic. 

 A basal streak and two median spots in lb, and two in la. 



Head black with a j'ellowisb white dot between the eyes, and 

 two on collar. Thorax black with pale dorsal and lateral marks. 

 Abdomen black above with pale lemon ochreous lateral dots. 

 Claws equal (but see f. reversa, p. 296). 



$. Expanse 62-66 mm. F.-w. much more rounded, and 

 dark areas usually tending to a browner shade. The trans- 

 parent patches are more clearly defined, those parts which in 

 the (J are thinly scaled, are here of the same depth as the 

 general ground-colour. The yellow patch in h.-w. is often of a 

 duller ochreous. In other respects the $ resembles the ^ . 



A. servona urientis, subsp. PI. Ill, f. 5(9). 



Ground-colour a much richer black. The f.-w. transparent 

 spots rather smaller, more clearly defined, and more obviously 

 scaled with white. Those in lb and 3 almost or quite absent. 

 In the h.-w. the yellow area is broader owing to the greatly 

 decreased extent of the basal black. On the underside the f.-w. 

 is correspondingly blacker, though the cell, transparent patches, 

 and bases of areas 6-lb are still almost devoid of scales. The 

 5 also has the ground-colour blacker, though scarcely so black 

 as in the (^ . 



The black spots of the h.-w. underside seem to be more 

 variable in this race than in most of the more western examples, 

 and Dr. Strand has proposed form names for the principal 

 variations of this feature.* These forms are as follows — 



f. depuncteUa. 



No black spots in cell, one to two in area 7. 



* I am not sure that the naming of forms on the variation of the 

 black spots is not carrying nomenclature to excess. There are 

 species of Acraca in which the number of black spots is so variable 

 that almost as many names might be made as there are spots on the 

 insects. In the present species the spots are not even constant in 

 both wings of the same specimen.
