four being- most coiiiiuoii ; \'l h.-is usually tin- onliii.iry s<-iisoria in the process, 

 which iiiav consist of three. Koxt rum — Reaches to third coxa-, li}?ht yellow 

 with dusky base and extreme ti|) dark. I'rolborri.i — Smooth, wider than the head, 

 hut very short, black or very dark green, without tubercles. Mc.so- and Metii- 

 tliorax — Muscle lobes well developed, dark brown to bl.ick, m iitral surface green 

 between coxa'. .Uidomcn — Well rounded and distinctly segmented, didl preen in 

 living specimens, but turning orange or yellow shortly after mounting, with four 

 rows of large, nearly circular, wax area.s which differ little, in color, from the 

 body and which are difficult to see in fresh specimens; for tliis reason they are uol 

 indicated in the drawing. The four glands or wax areas occupy nearly an entire 

 abdominal segment, and each is tilled with fine pores. In the living forms the 

 abdomen is covered with a thick coating of long flocculenee, while there is little 

 or none on the head and thorax of the winged forms. There are to be noticed 

 dark spots along the lateral sides of the abdomen in cleared specimens only, 

 these being located .it the union of the segments. Anal i)l,ite, well rounded, dark. 

 Cornicles — Wanting. Legs — Normal, dark, rich brown, with very few hairs. In 

 fresh specimens the coxa? are dark, femora, tibia?, and tarsi greenish brown. 

 Article I of the t.irsus (Figure 2'2.'i G) is very short and triangular, the second 

 article long with the upper end extending to the tibia, nearly seven times as long 

 as I. Wings — Dusky hyaline throughout, normal in size. Primari/ — Length .'i 

 nun., width I nnn. \^enation norm.al for this genus. Costal vein widest at base 

 and narrowing to the stigma, dark brown. Subcostal much wider than the costal, 

 dark brown. Stigma short, bluntly pointed at the end, nearly three times as long 

 as bro.id, dark brown, with the lower margin darkest, with the entire shadin"- 

 somewhat mottled, lower margin with a row of short curved hairs. Stigmal vein 

 arising from the stigma slightly beyond the middle, curved throughout the basal 

 one-third, may or may not be slightlj' undulate, rather long, wider at base. First 

 and second discoidals with bases close together, and arising near the middle of the 

 subcostal, slightly curved with the convex surface towards the tip of the wing, 

 diverging from bases to ti))s, which are far apart (the tip of the second discoidal 

 is midway between the tips of the first and third discoidals. Second discoidal 

 with much deeper bend than has the first. Third discoidal obsolete for a consid- 

 erable part of the base, the basal tip being nearly even with the middle jioint of 

 the second discoidal and midway between it and the lower margin of the stigma, 

 straight, slightly curved downward, or undulate, ti]) reaching the wing margin 

 slightly nearer the tiji of the stigmal vein than midway between the tips of the 

 stigmal vein and the second discoidal. All veins yellowish to amber. Secondari/ — 

 Length 2 mm., width 0.6 mm. Subcostal vein strongly bent downward at the 

 bases of the discoidals, one-third the distance from its base to tij). Discoidals with 

 bases close together. First discoidal short, slightly undulate. Second discoidal 

 nuich longer than the first, nearly in a line with a continuation of the subcostal 

 before it bends, well curved, with convex surface upwards. All veins yellowish. 

 Style — (Figure 223, 1). Tubercle-shaped, with base nearly twice as wide as 

 the length, green or dusky brown, does not project beyond the last abdominal seg- 

 ment or the anal plate.
