circular (Figure 17fi 1'), VI one large circular, liosliiim — Reaching third coxa", 

 light with base and extreme tip dark. Thorax — Dark olive green, 

 nearly black. Abdomen — Olive or browni.sh-green, not a.s dark as head 

 and thorax, segmentation on dorsum plainly marked by dejjressions. 

 (\)niicles — (Figure 17()C). Cylindrical, slightly widest at base, with trumpet- 

 mouth, basal one-tJiird dark, remainder very light, length 1 mm., 

 average width 0.21 mm. Legs — Long and slender, transparently-light 

 in color, with coxa?, ti|)s of femora, tips of tibia-, and all of tarsi dark, nor- 

 mally haired. Wings — Clouded along the veins. Primary — (Figure 176 A and G). 

 Length 2.S mm., width 0.8 mm., venation very variable as shown in drawings of 

 "G," costal and subcostal normal and distinct, with apical one-half clouded along 

 borders ; stigma nearly as broad as long with transparent area in center ; stigmal 

 vein, variable, clouded, when entire, is well curved throughout entire length, 

 deeply curved so as to nearly touch first branch of third discoidal. This vein is 

 sometimes only indicated by mere fragments and the clouded band, but the band 

 is sometimes broken, as shown in drawings ; first discoidal curving slightly 

 inwardly, almost at right angles to the subcostal, short with very 

 wide clouded borders ; second discoidal vein curving inwardly, extending 

 towards wing-tip; third discoidal with distinct first branch and rudi- 

 mentary or indicated second branch ; first branch arising nearly in center 

 of the vein, second branch indicated near the very tip. Secondary — Length 1.25 

 mm., width O.-i mm., veins lightly clouded, subcostal strongly bent at the junction 

 with the second discoidal, first discoidal straight, short, arising just inside of the 

 basal half of the subcostal, clouded borders, widest at base and tapers to point at 

 end of the vein; second discoidal arising two-thirds the distance from the base to 

 the tip of the subcostal, short, basal half clouded. Discoidals extend only three- 

 quarters distance from subcostal vein to lower margin of wing. Style — Ensiform, 

 sickle-shaped, color of abdomen, one-half as long as cornicles.

Prevailing coloi — Very dark olive green to black throughout, dorsum with six 

 longitudinal rows of small tubercles, a tubercle on every segment in each row,

 tubercles of the four lateral rows have but one white capitate hair each, several 

 such hairs on head and frontal tubercles. Head — Nearly square. Antennae — On 

 prominent, approximate frontal tubercles, longer than body, nearly filiform, color
