Crenis natalenms, Boisduval, Voy. de Deleg. ii. p. 592 (1847).

The single example is rather darker than the specimens in the 

 Museum series, but differs in no other respect. 



55. Crems crawshati, sp. n. (Plate LX. fig. 5.) 



Greyish blue, the whole centre suffused with rosy lavender ; the 

 base and costa of primaries, and the body above, slightly greenish ; 

 wngs with slightly sinuated black outer margins and delicate white 

 fringes : veins black externally ; disk of wings crossed by three 

 series of black spots beyond the middle, the innermost series 

 angulated and very oblique on the primaries, almost obliterated on 

 the secondaries, the first two spots of the series cuneiform, the 

 others rounded ; second series double towards costa, the first three 

 spots being preceded by elongate blackish streaks ; a minute white 

 dash between the first pair, which would otherwise be lost in the 

 black veins, of which they form a mere thickening ; the spot on 

 interno-median area divided ; submarginal series formed of more 

 or less lunate spots ; costa of secondaries and hairs on abdominal 

 area somewhat brownish. Underside most like that of 0. rosa, but 

 deeper in colour, the primaries with two complete series of black 

 spots towards outer margin, the first of the inner series and the 

 first two of the outer series enclosed by a pale silvery blue apical 

 costal streak, the three following pairs united by longitudinal 

 streaks of the same colour, the fourth pair by a few blue scales ; 

 all the spots of the outer series united to pale blue marginal spots ; 

 extreme margin blackish, with white fringe : secondaries having 

 the general aspect of those of G. rosa, but entirely different in 

 details ; costa broadly pale blue, with a black interrupted longi- 

 tudinal line above the costal vein ; a black spot below it at centre 

 of costa and a cuneiform orange spot enclosing the precostal 

 veiulet ; a broad almost triangular blue patch nearly covering the 

 cell, within which are black irregular characters similar to those of 

 Argynnis or EutJialia ; a blue streak runs down the abdominal 

 border, and a second, enclosing the submedian vein, unites with it 

 to form a large anal patch, which encloses a slender black sub- 

 marginal line and the last two spots of the discal series ; from the 

 submedian streak a curved series of triangular blue spots, termi- 

 nating externally in blackish angular markings, runs across to the 

 cell, wdth the large patch on which the triangular spots are fused ; 

 two series of black spots parallel to the outer margin enclosed in 

 clavate longitudinal pale blue streaks, the outer series submarginal. 

 Body below bluish white. Expanse of wings 65 millim.
