right inwards on the inner margin ; this series is followed by a broad 

 irregular white area and the marginal series is like that in the pri- 

 maries except that the inner brown line is fine and the brown inter- 

 nervular spots larger ; there are two black anal spots beautifully iri- 

 descent with metallic pale blue, and the upper of the two spots has a 

 broad red crescent on its inner edge. 



?. Blue of a purer or truer blue than the male and covering more 

 than three-quarters of the primaries and four-fifths of the secondaries ; 

 the wings are of the same delicate texture as in the male, the pattern 

 below being precisely that of the male. 



I am indebted to M. Oberthur for the loan of this beautiful 

 little species. Holland's figures on plates 30 and 31 in his 

 Butterfly Book give a fairly correct representation of the 

 species found on the mainland, but it is considerably different 

 from the Cuban insect and is certainly distinct from it ; it is, 

 I have little doubt, catilina Fab. 



H. catilina Fab. 



This species was described by Fabricius in his Ent. Syst, 

 Vol. Ill, p. 304 (1793). The description is probably taken 

 from a female, the underside being described as "pallidiores 

 fasciis plurimis albis, angulus ani ocellis duobus dimidio 

 cseruleis atrisque." "Habitat in Americae meridionalis Insulis 

 Dr. Pflug." In the British Museum (South Kensington) there 

 are specimens from Haiti and St. Domingo which agree ac- 

 curately with the descriptions of Fabricius and they also agree 

 equally precisely with Holland's figure (1. c.), Plate 30, f. 45. 



The differences between this and ammon are easily recog- 

 nizable in the primaries on the underside. The transverse 

 row is not a continuous band but is an irregular row of 

 separate spots touching each other; in the secondaries the 

 basal series of dark spots consists of four, there being an 

 additional one just below the cell; in ammon there are only 

 three spots, viz. : below the costal vein, in the cell and on the 

 inner margin ; in catilina the color is gray up to the transverse 

 band in both wings, throwing up the white postmedian area 

 strongly in contrast. Ammon has the underside much whiter 

 all over. Again, the upperside has none of the delicate tone of 

 ammou, but is, as Holland describes it, lilac blue; it is quite
