circular sensoria scattered over the surface; IV (Fig. 191, 1, 2, 3, 4) with from 

 one to three large circular sensoria, which may be scattered at the base or near 

 the apex of tlie article, but thej' are usually on the basal half ; V with from two 

 to three large circular sensoria (Fig. ipi, 5, 6) and in some instances one small 

 one as shown in drawing. There is usually but one sensorium. The small group in 

 the nail-like process of article VI is shown in Fig. 191, 7. Rostrum — Reaching to 

 second coxse, with dark base and tip. Prothorax — More than twice as wide as 

 long; dark, with very small lateral tubercles. Meso- and MetatJtorax — Wide, black, 

 with prominent muscle lobes. Abdomen — Well rounded, dull green or brownish- 

 green, bearing a transverse row of quite long white flocculence on each segment 

 (not shown in the cut), which may nearly cover the entire body. Anal plate 

 (Fig. 191, H) dark, hairy, three small marginal tubercles on eacli side. Cornicles 

 — (Fig. 191, F). Short, somewhat ej'lindrical, witii wide mouth, base little wider 

 than apex, narrowest just before the mouth, imbricated, black, longer than the 

 style, length O.I6 mm. Legs — Moderatelj- long and hairy, black or dark brown 

 throughout. Wings — Large, hyaline. Primary — Length 3.3 mm., width 1.2a mm. 

 Costal vein stout, dark brown ; subcostal wide, brown ; stigma long and narrow, 

 widest at the base of the stigmal vein, from whence it narrows to a point at the 

 wing margin, the opposite sides are nearly parallel, length 0.95 mm., width 0.1 (J 

 mm., amber brown ; stigmal vein arising three-fifths tlie distance from the base 

 of the stigma, strongly curved throughout first lialf and slightly curved tliroughout 

 the apical half, rather long, brown or amber ; first and second discoidals straight ; 

 third discoidal twice branched, first branch arising one-third the distance from the 

 base to the tip, short, parallel with the apical one-third of the stigmal vein, brown 

 arising very near to the tip of the first branch (three-fourths the distance from the 

 base to the tip), short, parallel with the apical one-third of the stigmal vein, brown 

 or amber. Secondary — Length 1.8 mm., width 0.65 mm.; subcostal vein curved 

 downwardly just beyond the base of the second discoidal and then curves down- 

 wardly to original level to tip of the wing; first discoidal arising just beyond 

 one-fourth the distance from the base to the tip of the subcostal, slightly curved 

 outwardly, does not touch the subcostal vein or the wing margin ; second discoidal 

 arising from the middle of tiie subcostal and nearlj' straight, does not touch sub- 

 costal vein, but extends to wing margin; all veins brown. Style — (Fig. H and I). 

 Bluntly ensiform, or conical, beset with stiff hairs, rough, dark, curving upward, 

 length 0.12 mm. 



APTEKOUS VIVIPAROUS FEMALE (Figure 191 B) 



Length of body not including style 2.2 mm., width of abdomen 1.3 mm. 



A larger and more robust form than the winged female. 



Prevailing color — Very dark green or brown, covered with transverse rows 

 of ratlier long white fiocculence on the bodj', giving it a grayish appearance. Body 

 gradually widening from head to the middle of the abdomen and tlien rounds off 

 to the style, robust. Head — With slight frontal tubercles, much wider than long, 

 dull green or brown. Eyes — Red. Antennae (Fig , E) — On very slight
