 dark; article I one-fourth at long as II. Wings — Normal, hyaline, with 

 venation constant and normal. Primary — Length 4 mm., width 1.4 mm. 

 Costal well developed to the stigma. Subcostal wide, rich brown. Stigma 

 rather long and narrow, with opposite sides nearly parallel, four times as 

 long as broad, pointed at tip, rich brown. Stigmal vein short and well curved, 

 arising beyond the middle of the stigma, the tip slightly farther from the 

 tip of the stigma than is the base. Discoidals well developed and normal : 

 first and second with bases quite distant, first straight, second bent out- 

 wardly, with convex surface towards the tip of the wing, third obsolete for 

 a short distance at the base, first fork near the middle, and second fork near 

 the tip of the wing. All veins rich brown with a slight dusky area at their 

 tips. Secondary — Length 2.4 mm., width 0.7 mm., venation constant, sub- 

 costal undulate, distinctly twice bent, first downward bend slight and at the 

 base of the first discoidal which is not far from the base of the wing (one- 

 fifth the length of the vein), the second downward bend is much greater than 

 the first and at the base of the second discoidal, which is nearly the middle of 

 the subcostal, first discoidal obsolete at the base, straight, reaching to tip of 

 wing, second discoidal bending slightly outwardly. Veins brown with dusky 

 spots at their apices. Style — Short, rounded, amber yellow or orange with 

 dusky tip.
