182 Busck Notes on Some Tortricid Genera 



Type. Male. U. S. Nat. Mas., No. 10,136. 



A striking, oddly ornamented species, very distinct from all other de 

 scribed species. The type was taken at light on an evening in June, when 

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

 Microlepidoptera. 



LIPOPTYCHA. 



Fore wings dusted with yellow scales ; in males w r ith costal 



fold kana, sp. nov. 



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



\/ Lipoptycha kana sp. nov. 



Labial palpi, head and thorax dark fuscous. Fore wings in male with a 

 short and narrow costal fold with an expansible hairtuft, not reach ing 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. 



Alar expanse: 17-20 mm. 



Habitat. Kaslo, British Columbia (Dyar). 



Type. Male. U. S. Nat. Mus., No. 10,187. 



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

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

 closely approaches bugnionana Duponchel, in general habitus and color, 

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

 sides possessing the costal fold in the males. 



y 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; uniformly 

 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. 



Habitat South Park, Colorado (Oslar). 



Type. Male. U. S. Nat. Mus., No. 10,138. 



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 

 bugnionana Duponchel, differing 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.
