the whole, its cephalic margin a continuation of the petiole, straight but curv- 

 ing around the apex, the caudal margin a long, sloping convexity ; the blade 

 is paddle-shaped, not quite one-half distad is deeply fumated (smoky brown) ; 

 the fumated area with its proximal margin oblique, running from the costal 

 edge disto-caudad. The discal ciliation of the blade consists of a single longi- 

 tudinal line of moderately long cilia running through about the middle of the 

 blade, but cephalad of the middle, terminating some distance before the sharp 

 base of the blade ; the cilia become somewhat more crowded and longer distad 

 and the line runs to the apex ; in the distal two-thirds of the fumated area, 

 cephalad of the distal third of the long, nearly central line, there are two 

 short lines of discal cilia running to the apical margin, the cephalic one 

 shorter (about 3 to 6 cilia), the caudal one slightly longer (about 5 to 7 cilia) ; 

 both lines may be somewhat confused in which case a third short line is indi- 

 cated ; around the blade margins is a row of fine discal cilia ; also of marginal 

 cilia which are fine but distinct, projecting out between the long primary 

 marginal ciliation ; these secondary marginal cilia are subequal in length to 

 the true discal cilia ; disk of blade free from cilia caudad of the nearly central 

 row. Marginal cilia very long, slender, graceful, equal at both margins, some- 

 what shorter around the apex, about 2]^ times longer than the greatest width 

 of the blade, about as long as the scape and pedicel combined. 



Posterior wings aborted, without a blade, merely a comparatively long, 

 acuminate bristle-like appendage, by far not reaching half-way to the base 

 of the blade of the fore wing, distinctly shorter than the scape, about a third 

 of the length of the petiole of the fore wing (excluding blade). 



Bulb of scape short ; scape very long, curved somewhat, slenderer in the 

 middle, slightly shorter than the second funicle joint, about four times the 

 length of the pedicel and twice or more the length of the club, distinctly 

 thickened at each end; pedicel obconic, usual, distinctly longer than wide, 

 slightly shorter than the proximal funicle joint ; the latter slender, about five 

 times longer than wide, longer than any of the funicle joints except the 

 second, shorter than the club by about one-half; second funicle joint abruptly 

 very long and slender, subequal in length to the combined lengths of the other 

 five funicle joints, very slightly thickened distad, rod-like, the proximal funicle 

 joint rod-like; third and fourth funicle joints abruptly very short, cylin- 

 drical ovate, not as long as pedicel, svibequal to each other ; funicle five a 

 fourth longer, six a fourth longer than five and distinctly thicker, somewhat 

 shorter than the pedicel. Club slightly larger, slender ovate, longer than 

 funicle joints four, five and six combined.' Pubescence soft, short, moderate, 

 not conspicuous.
