D. Abdominal segment 3 with the longitudinal green stripe on each side 
of the dorsum not confluent with the transverse basal green line; 
labrum usually margined with brown (younger) or black (older), 
especially at the sides. Males with the hamule strongly curved 
throughout its length, its apex blunt*, the metallic blue of the 
superior and anterior surfaces of the frons extending also on to 
the lateral surfaces thereof, no posterior process to the genital lobe. 
Females with the lobes of the vulvar lamina shorter than the width 
of the interval separating them, this interval much wider at the 
apices of the lobes than deep; abdomen subequal in length to 
the hind wing. Abdomen, $ 36-40, 9 36-38 ; hind wing, 3 32-35, 
? 36-388 mm. 
DD. Abdominal segment 8 with the longitudinal, green stripe on each side 
CC. 
of the dorsum confluent with the transverse basal green line; labrum 
pale, unmarked. Males with the hamule not so strongly curved, 
nearly straight in the middle, bent near the apex, which is acute t, 
the metallic-blue of the superior and anterior surfaces of the frons 
not extending on to the lateral surfaces thereof. Females with the 
lobes of the vulvar lamina longer than the width of the interval 
separating them, this interval narrower (at the apices of the lobes) 
than deep; abdomen longer than the hind wing (¢ of postlobata 
unknown). 
E. Genital lobe of male with no posterior process. Abdomen, ¢ 36-39'5, 
? 388-40; hind wing, ¢ 31-34, 2 82:5-36 mm. . 
EE. Genital lobe of male with a posterior process. g. Abdomen, 
36-39°5, hind wing 80°5-34'°5 mm. 
° 
Hind wings with 8 (g), 3-42) rows of cells between A, and the 
wing-margin posterior to the membranule, 10°5-13 mm. wide at 
arculus, 10-12 mm. wide at nodus; genital lobe of the males with no 
posterior process. 
F. Abdomen of the male longer than the hind wing, hamule strongly 
curved throughout, but not tapering to the apex, which is, however, 
acute. Proportions of the lobes of the vulvar lamina similar to 
those above stated for vivaz. Abdomen, § 36-48, 2 37-45; hind 
wing, ¢ 34°5-39'5, 9 36°5-43 mm. 
FF. Abdomen of the male shorter than the hind wing. 
G. Hamule of the male not equally curved throughout, but almost 
straight in its middle, bent near the apex, which is less acute and
