18 Psyche [March-June 
Differing from the two preceding species in the following: 
aedeagus (similarly proportioned and shaped) distinctly larger; 
uncus lobe slightly longer; comb in actual breadth intermediate 
between dominica and ammon but appearing as broad as in 
ammon owing to the greater development of first and second 
teeth, the latter being intermediate in size between dominica 
an d ammon , and the former about twice longer than in dominica 
and about one and one-half times longer than in ammon ; the 
rest of the comb more finely serrated, with a greater number of 
teeth (21) than in the two preceding or in the next species. 
Measurements (in mm.): aedeagus 0.83, suprazonal portion 
0.28, subzonal 0.55 with breadth (in lateral view) 0.15; penis 
0.7. Furca 0.42. Sagum 0.43. Vertical/Horizontal extension: 
forearm 0.2/0.04, humerulus 0.05/0.16, shoulder 0.13/0.06, 
uncus lobe 0.27/0.06. Valve 0.71 with breadth 0.42; comb 
0.15; first and second teeth: length (measured as in dominica 
and ammon) 0.039 and 0.02.

Differing from the three other species in the following: ven- 
tral outline of suprazonal sheath in lateral view curiously con- 
cave above the zone and then angled, this being due to a higher 
(at two-thirds from the zone) and still more distally facing 
1 This is an aberrative male of ssp. thomasi showing a pretty contrast between 
the blurred and darkened disc of the underside of both wings and the strongly 
developed white cretules, while a very luminous scintilla rims and almost engulfs 
the Cui praeterminal mark. I doubt very much that this can be a subspecifically 
constant combination of characters on Crooked Isl.
