of midlength, but the vein itself continuing as a dark line through 

 this spot; cell Ml with 1 distal pale spot, located at about its length 

 from wing margin; cell M2 with a large pale area lying between 

 medial and mediocubital forks, a large rounded distal pale spot at- 

 taining wing margin; no pale area in base of mediocubital fork, a 

 large rounded pale spot dis tally in cell M4, broadly meeting wing 

 margin but not touching vein M3+4; a large transverse, double pale 

 spot distally in anal cell, the posterior portion sometimes very faint. 

 Macrotrichia moderately sparse on distal third of wing and con- 

 tinued proximally in cell M2 and nearly to base of anal cell; costa

extending to 0.68 (0.65-0.71, n=14) of distance to wing tip; radial 

 cells with distinct lumens, the second broader and about twice as 

 long as first. Halter pale. 



Abdomen: Dark brown. Spermathecae (fig. Zd) 2 plus a rudi- 

 mentary third and a long sclerotized ring; subequal, each measuring 

 0.065 x 0.046 mm, ovoid, tapering gradually to variable, short, 

 sclerotized necks. 



Male. — Similar to the female with the usual sexual differences; 

 wing length 2.07 mm; antennal plume sparse, last 3 antennal seg- 

 ments with lengths in proportion of 75-72-70. Genitalia (figs. 3/, g)
