outwards nearly to the depressed apex itself, thence back at a very 

 acute angle to a point opposite its origin, whence it is curved down- 

 wards and outwards towards the middle of the apical margin, with 

 which it runs parallel until again curved above the anal angle, whence 

 it can be traced to the triangular semi-transparent patch (up to which 

 its course has already been described) ; the black line is margined 

 on both sides with whitish-ochreous lines above the middle of the 

 apical margin, and a short line of the same colour extends along the 

 upper half of the margin to the apex, there is also a short streak 

 above the anal angle ; cilia whitish, with much dark fuscous mottling, 

 especially at the apex, at the middle, and at the anal angle, but 

 with a dark line running throughout them near the base. The 

 markings to a great extent show through on the underside. 



Hind wings semi-transparent, pale rosy seneous ; the apex and 

 outer half of the dorsal margin banded with blackish, as is also the 

 costal margin ; with three blackish spots, one below the middle of 

 the costal band, one below the middle of the wing, and one at the 

 abdominal angle (these are inconspicuous in specimens in less good 

 condition) ; a slender whitish line runs parallel with the dorsal 

 margin throughout the wing-length : cilia pale cinereous, with a dark 

 line running through their middle. The markings to a great extent 

 show through on the underside. 



Abdomen whitish ochreous, mottled above with reddish brown 

 mixed with dark fuscous ; some slight lateral tufts along the segments 

 are also of this mixed colour. 



Legs pale whitish ochreous, unspotted.

I have also two specimens of this species from the Zeller Collection 

 collected either by Baron von Nolcken or Petersen ; but I have not 

 been able to trace whether they were taken in the West Indies, 

 Panama, or Colombia.

This species has apparently a wide distribution, and is very nearly 

 allied to Trichoptilus (Aciptilus) calif ornicus, Wlsm., from Northern 

 California ; it has, however, darker hind wings and less white upon 

 the surface and cilia of the tore wings. Specimens from Mexico and
