ORTHEMIS. 23 
B,. [Labium with a broad (25 mm.) median black band; femora and 
tibize superiorly darker, almost black on tibiz ; tips of wings to distal 
end of pterostigma dark brown; brown stripes on sides of thorax 
subequal in width to the intervening yellow (which is deeper than 
in ferruyinea) , unbroken, those of metepisternum and second lateral 
suture united by a line only, a slight pale antehumeral stripe anterior 
and additional to that of ferruginea ; abdomen more slender, e.g. 
3°5 mm. wide at base of segment 8, apex of outer branch of genital 
hamule of ¢ less produced. Abdomen, ¢ 82-845, 2 31°5-338; 
hind wing, ¢ 40-44, 9 42-43 mm... . . . « Subspecies sulphurata*.] 
AA. Hind wings with three rows of cells between A, and the hind margin at 
level of hind angle of triangle. Labium with a median black or dark 
brown band. Colour-pattern of sides of thorax (except in attenuata ?) 
different from that of preceding species in that the brown stripes of 
the humeral suture and mesepimeron have united throughout their 
length. Femora and tibie superiorly dark brown. Pterostigma 
4°5-5°5 mm. 
C. Arculus at, or proximal to, the second antecubital on the hind wings ; 
pale stripes on sides of thorax narrow, that on the mesepimeron 
‘5 mm. in width. Abdomen bright red, segment 2 1:1-1°4 times 
as wide as base of segment 4, segment 4 1:5-2 times as long as 
wide; anterior lamina projecting not half as far as hamule ; hamule 
like that of ferruginea, but larger and heavier, apex of outer branch 
less produced. ¢: abdomen 295-31, hind wing 38-40 mm.

CC. Arculus distal to the second antecubital on the hind wings and, 
usually, also on the front wings. 
D. Dorsum of abdominal segments 4-7 chiefly reddish or luteous with 
at most only a narrow darker stripe each side ; pale stripe on the 
mesepimeron 1—-1:5 mm. wide. . 
E. Genital hamule ¢ similar to that of ferruginea, but its outer 
branch less produced, anterior lamina projecting almost as 
much as the hamule; abdominal segment 2 1°5-1:7 (3), 
15-2 (¢) times as wide as base of segment 4, segment 4 
325-4 times as long as wide. Abdomen, ¢ 34-88, 2? 34-37 ; 
hind wing, ¢ 37-41, 9 87-40 mm. . ...... . . 8. levist. 
EE. Genital hamule § more prominent than in any other species 
of the genus, more prominent than anterior lamina or genital 
* sulphurata, Hagen, Stett. ent. Zeit. xxix. p. 281 (1868), is introduced for sake of comparison (see 
Tab. IX. fig. 35). It is found in Ecuador, Peru, British Guiana, and perhaps Barbados, though I am 
doubtful of the identity of the single specimen from this locality. 
+ I am unable to separate the females which, on geographical grounds, appear to belong to levis and to 
cultriformis respectively.
