SYSTEMATIC PORTION 
GENUS OLENE Hbn. (Type, mendosa Hbn.) 
Olene Hubner, Zutr. Exot. Schmett. II, 19. (1823) ; Moore, Lep. Ceylon, II, 95 
(1883) ; Hampson, Moths Brit. Ind. I, 452 (1802); Neumoegen & 
Dyar, Jour. N. Y. Ent. Soc. II, 30 (1804). 
Parorgyia Packard, Proc. Ent. Soc. Phil. III, 332 (1864). 
We have been unable to secure any specimens of the type species 
of Olene, which occurs in Java, for examination; if mendosa should 
prove generically distinct from our N. Am. species, then these latter 
will fall under Packard’s genus Parorgyia. Packard specified no type 
when erecting this genus; as first species he lists “achatina Hbn.” but 
the species he really had before him, as we have verified by photographs 
of the specimens in the Harris Coll. mentioned by him under this 
heading, was atomaria Wk. (obliquata G. & R.). The second species 
mentioned, “Jeuwcophaea A. & S.” was evidently unknown to him; we 
believe therefore the safest course would be to consider basiflava Pack., 
the 3rd species listed, genotype. All three species are in any case con- 
generic, so that no confusion is liable to ensue. 
We offer the following generic definition, based on N. Am, 
material. 
Antennae bipectinate, very lengthily in ¢, shortly in 9 ; eyes naked, round; 
palpi porrect, extending beyond front, heavily clothed with hair beneath, almost 
concealing 3rd joint, which is short; front smooth; thorax clothed rather roughly 
with hair and hair-like scales, metathorax with prominent divided tuft of metal- 
lic scales; abdomen with button-like tufts of metallic scales on 2nd and 3rd seg-
