tlic base of tlif scgiiu'iit and tlu' to)) aj^aitist tlic iiu-sotiiorax. .tlxlomcn — Scarcely 

 wider than tlie thorax, not distinctly segmented, hairy, light green witli median 

 dorsal black ))atclies and transverse dorsal dark hands across the last two 

 abdominal segments. Of the dorsal jjatches the first is very small and is on tli(; 

 first segment, tlie second is large and exten<ls to the lower margins of the cornicles. 

 Anal plate rounded and dusky green. Coniiclcs — (Figure 2.'!0 J). Slightly 

 longer than the width of the base, base widest, very slightly or not constricted 

 before the apex, mouth flaring but very little or none, with ))arallel broken lines 

 around surface, light green (concolorous with surrounding body area), length 

 0.08 mm., width of the base 0.()7.'5 mm., width of mouth O.OKi mm. Lci;x — Small, 

 slender, hairy, transjjarently white or light green throughout. JViiigs — Normal, 

 hyaline. Primari/ — Length 1.8 mm., width O.fiS mm., margin constricted at the 

 ti]) of the stigma, venation fairly constant, but variable as in nearly all members 

 of this tribe. Costal, wide and distinct, dusky brown. Subcostal little wider 

 than the costal, dusky brown. Stigma quite oval, tip blunt or rather sharp, short, 

 dusky brown, of a uniform color throughout, lower margin hairy, length O.i.') mm., 

 width 0.1 mm. Stigmal vein short, well curved throughout, but strongest in basal 

 half, tip clouded, arises nearer the tip than the middle of the stigma. First dis- 

 coidal arising beyond the middle of the subcostal, straight or curved inwardly. 

 Second discoidal sub-obsolete at the base, straight, not reaching the margin of 

 the wing, base midway between the bases of the first and second discoidals. Third 

 discoidal normally twice-forked, obsolete at the base, first fork one-third the dis- 

 tance from the base to the tip of the lower branch of that fork, second fork 

 one-half the distance from the first fork to the tip of the wing, or more often 

 nearer the tip of the wing. Tips clouded. This vein is often but once forked 

 as has been observed in so many of the small species taken here. All the veins are 

 dusky brown in color. Secondari/ — Length 1.2.5 mm., width O.t mm. Normally 

 with subcostal and two discoidals. Subcostal undulate with strongest downward 

 curve below booklets and beyond the base of the second discoidal. Discoidals very 

 light, bases not very far apart, the base of the second near the middle of the 

 subcostal, bases also obsolete, or nearly so. First vein slightly curved inwardly, 

 second straight. Style — (Figure 230 H). Short, tip nearly straight across with 

 large spine on each lateral corner, base much wider than apex, slightly dusky 

 or light green, length 0.05.') mm., width of base 0,075 mm. 



APTEROUS VIVIPAROUS FEMALE (Figure 230 B) 



Length l.l- mm., width of the abdomen 0.8 mm. Hodi/ — Wide and very flat, 

 covered with long tuberculate hairs. Prevailing color — Transjiarently light green 

 throughout. Head — Small, narrower than the thorax, rounded, hairy, without 

 antennal tubercles, pale light green. Ei/es — Compound eyes, bright red, with 

 tubercles. Antennae — (Figure 230 F, G). Nearly as long as the body, reaching 

 beyond the bases of the cornicles, very slender throughout, but a mere filament ; 

 apical third and remaining articles imbricated, colorless or transparently white 

 throughout, very few hairs. Lengths of the articles: I, 0.065 mm.; II, O.Ot mm.; 

 Ill, 0.25 mm.; IV, 0.1? mm.; V, 0.18 mm.; VI, 0.1.2 mm. (base 0.12 mm., filament
