esting anomaly of the venation, though the specimen from Venezuela has 

 in all wings the usual venation. The apical end of the cell is usually 

 formed by the radius and the upper branch of the sector meeting shortly 

 before the tip of the wing, forming a curve from which a short vein 

 emanates. Now in the Brazil specimen the upper branch of the sector 

 runs straight to the tip of the wing ; the radius ends a little before and is 

 not connected with the sector by curving down, but by a straight trans- 

 versal, parallel to the other transversals. The cell is therefore not closed, 

 as usual, at the end by a curve. The radius is connected with the margin 

 by a costal originating at the same point with the last transversal in the 

 cell below. The same arrangement of the venation occurs only in O. 

 Westiuoodl. That it occurs in O. riificapilla as an aberration is rather 

 important, and it will help to a right understanding of the venation.

Winged male. Length of body 7 mill., exp. of wings 12 mill, (both 

 approximative). Body black, sub-opaque, covered sparingly with dark 

 hairs. Head very little longer than broad, about quadrangular, the sides 

 very little sloping to the rounded hind angles ; a large shallow depression 

 on the middle of the disk above, in the centre of which is a very faint 

 short elevated longitudinal line ; eyes black, large, but less prominent 

 than in O. ruficapilla, reniform ; antennae with only 19 joints present, 

 which are nevertheless longer than head and thorax together, yellowish 

 to 8th joint, the following successively darker, fuscous nearly blackish, 

 polished ; all with long fuscous hairs ; basal joint cylindrical, stout, a 

 little darker than the following, reddish yellow ; 2nd small, as long as 

 broad ; 3rd as long as the two basals together ; 4th half as long as 5th, 

 pyriform; 5th to loth successively longer, pyriform ; all following shorter, 

 a little thickened after the middle ; labrum short, half as long as broad, 

 rounded, yellowish at base and sides ; the middle and margin blackish ; 

 max. palpi dark fuscous, thick, ist to 4th joint short, about alike, 5th 

 longer, sub-acute ; labial palpi similar, last joint longer ; all palpi clothed 

 with paler hairs ; mandibles black on tip ; mentum large. Prothorax 

 short, half as broad as the head, enlarged to the wings, with a faint median 

 longitudinal impressed line and a deep anterior transverse sulcus, pro- 

 longated shortly along the oblique side-margin ; mesothorax rather longer 

 than broad ; metathorax nearly quadrangular. Legs shining black, clothed
