the subtriangie, the triangle, and all tliat portion of the wing, at least, which lies below 

 M14.3; another almost hj'aline space in the hind-wing includes all the cells below A, 

 embracing the anal loop, as well as the triangle, subtriangie, and a few of the cells 

 immediately beyond them. Reticulation, including C, black. No creamy spots at the 

 wing-bases. Pterostigma 3 mm. long, dark reddish-brown, unbraced. Membranule 

 4:'5 mm. long, whitish. Venation generally more open than in the female of *S'. eusta- 

 lacta Burm., the type of the genus. Antenodals of the first series 12 in the fore-wings, 

 and 8 in the hind-wings. Postnodals 7-8 in the fore-wings, 9 in the hind-wings. 

 Arculus in the fore-wing very oblique, in the hind-wing more vertical ; in all the wings 

 straight, or nearly straight, arising at or very near the level of the second antenodal of 

 the first series. Only one cross-vein in the supertriangle in all the wings. Median space 

 with a single cross-vein only in all the wings. Four cubito-anal cross-veins in each of 

 the left wings, and five in each of the right wings. Triangles and subtriangles of the 

 fore-wings free. Triangles of the hind-wings with one curved cross-vein in each ; the 

 convex side of the cross-vein directed anteriorly. Discoidal area in the fore-wings 

 commencing with a double cell, followed by three single cells, then by a few double 

 cells, succeeded by several rows of cells. Discoidal area in the hind-wings with at first 

 a few single or double cells, rapidly giving place to several rows of cells. Four 

 bridge-veins in all the wings. Hind-wing triangle not retracted ; the distance from 

 the arculus to the inner angle of the triangle, measured along the cubitus, is somewhat 

 more than half the length of the triangle. Anal loop in the hind-wing consisting of a 

 single enclosure, and containing 8 cells in the right wing and 7 cells in the left. 



Legs: coxiB light reddish-brown; femora light reddish-brown, black at the apex; 

 tarsi and claws black. Abdomen very dark reddish-brown, almost black, with a pair of 

 conspicuous yellow spots on each of the segments 2, 3, and 4, lying on each side of the 

 mid-dorsal carina, near the middle of the segment; similar but smaller spots probably 

 present on 5, 6, and 7 ; body apparently constricted at 4, but, as it is crushed laterally, 

 its shape cannot be stated with certainty ; 8 and 9 progressively smaller, and cut oft' 

 obliquely at the apex; 10 very small, and, like 9, directed conspicuously upwards; 

 a tuft of very long hairs springs from the ventral surface of 9, and a similar tuft from 

 10 ; apex of abdomen hairy. Anal appendages black, subconical, pointed, barely 

 projecting beyond the apex of the abdomen. Ovipositor : lower pair of blades dark 

 reddish-brown, nearly straight, concave within, parallel, spatulate and incurved at the 

 tips, projecting considerably beyond the apex of the abdomen ; upper pair of blades 

 black, stout and curved in the basal half, then parallel with the lower pair, divergent, 

 concave within, not reaching to the level of the end of the abdomen.
