LEPIDOPTERA OF THE FAMILY ZYG^NID/T:. 349 



18. S. FRANCISCA, n. sp. 



$ . Allied to S. cerbera, larger ; hyaline spots very small, nearly as in 

 S. creusa, but the secondaries with a large oval spot near the base 

 between the cell and abdominal margin : expanse of wings 39 

 millims. 

 Sierra Leone {Foxcroft). Type, B.M. 



We have Wo examples of this species in the collection; it is 

 probably the vrestern representative of S. cerbera, although (ex- 

 cepting in the banding of the abdomen) it more nearly resembles 

 ^. creusa. 



As an instance of the strong sexual instincts of this family, it 

 may be mentioned that the type of this species was taken in 

 copula with a male of Tascia instructa, Walker, which led the col- 

 lector to suppose them to be sexes of one species ; it is not, how- 

 ever, at all an uncommon occurrence in this family to find two 

 males coupled together. 



19. S. FANTASIA, n. sp. 



Closely allied to S. cerbera, but the three diseal hyaline spots of prima- 

 ries united by the introduction of a fourth spot between them, so that 

 together they form a quadrifid hyaline band ; the central spots also 

 more divergent, the lower one being lengthened at each end and ex- 

 tending transversely beyond the submedian nervure; basal spot longer : 

 expanse of wings 36 millims. 

 Cape of Good Hope {Drege). Type, B.M. 



Perhaps a curious aberration of ^. cerhera, tending towards the 

 ;S^. pactolina group. 



20. S. MONTANA, n. sp. 



Closely allied to S. latreillii, but with all the hyaline spots, excepting 

 the two nearest to apex of primaries, much enlarged, giving it much 

 the appearance of S. thelebus : expanse of wings 40 millims. 

 India (Elliott). Type, B.M. 



Difters from S, thelebus and S.fenestrata in having the subapi- 

 cal spots of S. creusa and 8. latreillii : it is in Mr. Moore's collec- 

 tion from Bombay. 



21. S. MANDARINIA, n. Sp. 



- Head black, frons with an orange spot ; thorax black, with a large spot 

 on prothorax and a smaller semicircular spot on metathorax orange ; 

 abdomen orange, segments narrowly edged with black : primaries 

 black, with six testaceous hyaline spots arranged as in S. thelebus ; 

 secondaries black, with a large, rounded, orange-edged, testaceous, 

 hvaline patch cut by the median nervure, its first branch, and the
