CATOCALA. 39 



these wings blurred, those on the centre of the wing forming almost an >S through the 

 combination of two reversed augnlated bands; the ground-colour pinky white densely 

 irrorated with black, and the bands sprinkled with ochreous scales, which give them a dull 

 greenish appearance, the bands themselves being of a bluish-grey colour, excepting the zigzag 

 one near the base, which is whitish with blackish borders ; (he basal area itself bluish grey : 

 the secondaries have no orange spots at apex, and the black band is almost rectangular 

 (L-shaped on the left-hand wing) : otherwise this species resembles C. elocata. Expanse of 

 wings 91 millim.

Catocala concubia. (Plate CX. fig. 10.) 

 Catocala concubia, Walker, Cat. Lcp. Het. xiii. p. 1210. n. Gl (1857). 



Very near to C. elocata, but the primaries more uniformly granite-grey : the secondaries 

 with the apex pure white, and with the black central baud augnlated externally and abbre- 

 viated at the first median branch; the whole of the fringe of these wings is also of a purer 

 white colour. Expanse of wings 90 millim.

Catocala luiicuba. (Plate CX. fig. 11.) 

 Catocala unicuba, Walker, Cat. Lip. II,t. xiii. p. 1210. u. 01 (ls.57). 



Perhaps only a variety of C. nupta ; the primaries are, however, rather more smoky in 

 tint, the markings a little less defined, and the pale patches better defined than in the 

 European species; the fringes appear also to be rather shorter. On the under surface the 

 white band across the disk is decidedly narrower, and the apex is grey instead of white : 

 otherwise there is no difference. Expanse of wings 78 millim. 



North India (Mrs. Manger). 



Walker says that " this species very much resembles C. nupta, but may be distinguished 

 by the different form of the exterior line of the fore wings, and by the much more excavated 

 band on the underside of the hind wings." Neither of these characters, however, proves to be 

 of the slightest importance when more than one specimen of C. nupta is examined.

Primaries above of various shades of stone-colour, grey, and olivaceous, crossed by the 

 two usual black lines aud other markings arranged as in C. zaltnunna * : secondaries of a
