CATOCALA.

these wings blurred, those on the centre of the wing forming almost an 8 through the 
combination of two reversed angulated bands ; tlie 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 ; the 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, WaJl-er, Cat. Lep. IL:t. xiii. p. 1210. n. 61 (1857). 
Very near to C. elocata, but tlie primaries more uniformly granite-grey : the secondaries 
with the apex pure white, and with the black central band angulated 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. 
North India {Mrs. Mauger). 
Catocala unicuba. (Plate CX. fig. 11.) 
Catocala unicuba, Wtdher, Cat. Lcp. lid. xiii. p. 1210. n. 01 (18.57). 
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 diff'erent 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. 
Catocala sponsalis. (Plate CXI. fig. 1.) 
Catocala sponsalis, Walker, Cat. Lep. Het. xiii. p. 1213. n. 67 (1857). 
Primaries above of various shades of stone-colour, grey, and olivaceous, crossed by the 
two usual black lines and other markings arranged as in C. zalmunna * : secondaries of a
