Remarks . This species belongs to the group in the genus 
Hemiargus that includes catilina Fabr., and its races, and 
dominica Moschl., though it is quite different from either. It 
bears a certain resemblance to dominica in the reduction in 
color of the basal spots, but there the similarity ceases. H. 
dominica , like ammon, is very light, with scattered brown 
markings, while bahamensis is dark, with the markings scarcely 
apparent. It is, perhaps, closest in appearance to thomasi, the 
Bahaman race of catilina. However, it can be distinguished 
readily by the pure white (though thin) lines, one on each 
wing, below, and in the reduced color of the basal spots, which 
are in thomasi jet black, as in the other catilina races. The 
reduction of the orange lunule below also seems characteristic 
of bahamensis.

upperside: 
Male. Fore wing dark brown with a reddish discal tinge. 
Base of wing blue. Hind wing dark brown, with a basal blue 
area as in the fore wing, but more extensive. The veins in this 
blue area are obscurely pencilled with dark brown. A row 
of inconspicuous dark spots adorns the outer margin. Fringe 
of fore wing brown, faintly whitish towards apex; that of hind 
wing white. 
UNDERSIDE : 
Male. Fore wing with the base, outer margin and apex dark 
gray; disk ruddy brown. A submarginal row of white dashes 
parallels the outer margin. In the disk is an interrupted, badly 
dislocated, double white line, and a double dash at the end of 
the cell. Hind wing dark gray brown. Obscure white dashes 
and white scaling are scattered over the entire surface with the
