A i^triking, oddly ornamented gpecief, very distinct from all other de- 

 scTil)ed species. The type was taken at liiiht on an evening in .Inne, when 

 Dr. \Vm Dietz and the writer spent the night on the island in pursuit of 

 Microlepkhjpfini. 



LIPOPTYCHA. 



Fore wings dusted with yellow scales ; in males with costal 



fold htna, sp. nov. 



Fore wings not thus dusted; in males without costal fold . haiiann, sp. nov. 



Lipoptycha kana sp. nov. 



Labial palpi, head and thorax dark fusc^ous. Fore wings in male with a 

 short and narrow costal fold with an expansible hairtuft, not reaching one- 

 fifth of wing length ; termen with slight sinuation below apex ; color uni- 

 formly dark shining fuscous, evenly and sparsely irrorated with golden 

 yellow scales ; at the lower end of terminal edge are three black dots. 

 Costa without any ornamentation. Cilia whitish fuscous, with darker base 

 and tips. Hind wings dark fuscous ; cilia lighter with dark base. Abdo- 

 men dark fuscous with yellowish anal brush ; legs silvery fuscous; under- 

 side of wings with faint greenish iridescence. 



Ahir ex[Hinse : 17-20 mm.

Tv/«'. — Male. U. S. Nat. Mus., No. 10,187. 



This is the species recorded as Hemimene plarnbana in Proc. U. S. Nat. 

 Mus., vol. xxvii, p. 929, 1904, but has nothing to do with that species ; it 

 closely approaches bngnionaiia Duponchel, in general hal)itus and color, 

 but is much larger, rather darker, and with sparser yellow irroration, be- 

 sides possessing the costal fold in the males. 



Lipoptycha banana sp. nov. 



Labial palpi, head and thorax dark greenish and bronzy fuscous. Fore- 

 wings with no costal fold in the male, termen nearly straight; uniforndy 

 dark, shining fuscous, with light brown and blackish scales evenly inter- 

 mixed, but without any golden irroration ; no costal or terminal markings. 

 Cilia whitish fuscous, with darker base and tip. Abdomen dark purplish- 

 fuscous, and brush ocherous : legs unicolored dark fuscous. 



Alar expanse: 20-24 mm.

This is by far the largest of all described species of this group ; it is 

 similar in form and coloration to the foregoing species and to the European 

 hiKjii'ioiKiiin Duponchel, difleiing from the former in the absence of yellow 

 irroration on the fore wing and in the absence of the costal fold in the 

 males; from the European species it differs, aside from its size, by the 

 total absence of any defined wing-ornamentation.
