 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 bro-ivn. 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. Diseoidals 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, amlier yellow or orange with 

 dusky tip.

Length of body 3.2 mm., width of abdomen 1.7 mm. Body— Large, oval, 

 tapering gradually towards both ends, covered with hair, pruinose, well seg- 

 mented. Prevailing color — From reddish brown to gray, covered with a fine 

 white powder which forms white or gray bands 1)etween the segments and a 

 light longitudinal row on the middle of the dorsum. Head — Rather large, 

 much wider than long, with front ocellus protruding forward, wide between 

 the antenna', amber brown. Eyes — Large, dark red. Antennae — (Figure 

 250, 8 and 9). Half as long as the body, not on frontal tubercles, hairy, each 

 hair on quite a large tubercle or swelling, T and IT amber yellow, III and IV 

 transparently white or yellow with dusky tips, V transparently yellow with 

 apical one-third dark, VI dark with extreme base light. Lengths of articles: 

 I, 0.1 mm.; TT, 0.08 mm.; Ill, 0.5 mm.; IV, 0.34 mm.; V. 0.35 mm.; VI, 0.5 

 mm., (spur 0.20 mm.) ; total 1.87 uun. T is widei' and longer than II. Ill 

 as long or slightly longer than VI, IV and V approximately co-equal though 

 V is often slightly the longer, VI as long or nearly as long as III. spur longer 

 than the base, but not nearly twice as long. TTsual number of sensoria on V 

 and VT. Eosfniin — Reaches to the third abdominal segment, transparently 

 white with black tip. Prothorax — Light, reddish brown with few darker 

 markin.iis and a litihter ba.sal band, with blunt lateral tubercle (Figure 2.50, 6) 

 just below the middle. Mc.so- and Metathorax — Each with irregular trans-
