Three examples, all females, taken at light in different 

 localities, viz., Rio Mamellos, a tributary of Rio Madeira ; 

 Juruena, on Rio Purus ; and Rio Jurua : the respective 

 dates being Jmie 1st, Sept. 24th, and Nov. 7th, 1874. 



Akin to H. hemonalis, Wlk., Cat. Lep. Het. B. M., 

 xvi., p. 228, from Brazil, but smaller; the wings 

 narrower and paler, and wanting the white apical 

 lunule, which is so conspicuous a feature in that species ; 

 the palpi also differ. In H. hemonalis they are blackish, 

 the 3rd joint fringed with black to the apex; in H. 

 munda they are greyish fuscous, the 8rd joint slender, 

 ivhite, with a laterally flattened brush of dark brown 

 scales in the middle projecting above and below. 



6. Hypena fuscipennis, n. s. 

 Fore wing dark fuscous, dusted with lilac-grey scales, especially 

 in the spaces beyond each of the three transverse lines. First 

 line oblique, 2nd sinuous, forming two rounded projections exter- 

 nally, and approaching the 1st on the inner margin ; the inter- 

 mediate space darkest, edged with fulvous lines ; beyond the 2nd 

 line is a greyish curved fascia, then a dark brown one ; sub- 

 marginal line pale, wavy, most distinct towards the anal angle ; 

 fringes dark fuscous, with a strong black basal line of dashes, 

 which scarcely form lunules. Hind wing dark fuscous, as are the 

 head, thorax, abdomen, and legs. Under side dark fuscous, with- 

 out markings. Expanse of wings, 30 mm.
