the middli' of the stigma, may or may not be sub-obsolete at tlic base, clouded 

 darker near the base, curved throughout the basal half, slightly undulate, apical 

 half nearly parallel with the upper branch of tlie second fork of tlie third dis- 

 coidal, dusky amber. First discoidal arising beyond the middle of the subcostal, 

 straight, often heavily clouded, more so than tlie other veins. Second discoid.il 

 with base nearer the first discoidal tlian the third discoid.il, ne.irly straight with 

 apical one-fourth curved inwardly, does not reach the wing margin, dusky amber 

 with faint clouded borders. Third discoidal only slightly variable, normally 

 twice-forked, with first fork .ibout one-third distance from the base and the 

 second fork half the distance from the first fork to the tip of the wing, the Ujiper 

 branch of the second fork longer than the lower, slightly clouded, dusky amber. 

 In only a few cases is this vtin once forked. Secondary — Length 1.8 nun., great- 

 est width O..") unn., d.irk clouded area .it the extreme tips, veins not clouded, vena- 

 tion normal with two discoidals. Subcostal vein strongly bent downward at the 

 base of the second discoidal, which is below the booklets; booklets just beyond tlii' 

 middle of the u])pcr wing margin. Discoidals with bases distant, one on either 

 side of the middle of the subcostal, both obsolete for a very sliort distance at 

 their bases, and both curve so tliat the convex surfaces are towards the wing tip, 

 the second vein curved most, equal in length, do not touch lower margin of the 

 wing. All veins dusky amber. Style — (Figure 2.S3, 2). Very short and broadly 

 conical, base three times as wide as the length, dark green, length 0.03 mm., 

 width 0.09 mm. 



APTEROUS VIVIPAROUS FEMALE (Figure 233 B) 

 I-cngth 2.75 mm., width of abdomen 1.6 mm. Body — Well rounded and 

 slightly plump, but not short, hairy, medium in size, dorsum with many lobes 

 and depressions. Prevailing Color — Very dark brown, reddish brown with black 

 markings or black with dull brown areas between the segments and along the 

 middle dorsum, shiny or dull. Head, rather small, wider than long, hair}', dark 

 reddish brown with dark margins or nearly black. Antennae — (Figure 233 E and 

 F"). About half as long as the body, bases distant, on the sides of the head, not 

 on frontal tubercles, hairy, articles I and II dark amber or reddish brown, III 

 with base yellow or amber and the remainder d.irk brown, IV, V and VI dark 

 amber brown with lighter areas at their articulations. Lengths of articles: I, 

 0.077 mm.; II, 0.035 mm.; Ill, 0.23() mm.; IV, O.M mm.; V, O.M mm.; VI, 0.18 

 nun. (base 0.105 mm., spur 0.075 mm.). I is longer or equal to II in length, but 

 wider. III is the longest article, being nearly twice as long as IV and V together, 

 IV and V are subequal and each shorter than VI, but longer than the base, 

 VI with ba.se longer than the s]>ur, though these are sometimes subequal. Sen- 

 soria on apical end of V and at the base of the s))ur on VI. Rostrum — Reaching 

 to the middle of the abdomen, yellow with dark base and tip. Prothorax — 

 Amber brown to dark brown with dark margins and amber middle, two depres- 

 sions, one on eacli side, near the middle, two fleshy lateral lobes near the base. 

 Mesothorax — Dark, nearly black, with middle amber or reddish brown area, 

 sides distinctly lobed with curved depression in middle of each. Mesothorax — 

 Short, nearly all dark, with amber or reddish middle, depression.s on each side,
