Abdominal segments i and 2 chiefly greenish-yellow, with a brown 

 stripe on each side (above the greenish-yellow auricles on 2) ; 3-10 

 chiefly blackish-brown, with the following yellow or orange markings : 

 a mid-dorsal line or very narrow stripe on 3-6 and 8-9, but on 7 oc- 

 cupying the whole width of the segment for its anterior two-fifths, 

 narrowing posteriorly on the remaining three-fifths, this mid-dorsal 

 line or stripe almost as long as each segment ; a basal spot on each side 

 of 3-6 occupying a third of the segment or less, the sides inferiorly of 

 7-10, sternites of 8-10. Inferior lateral margins of 8 and 9 enlarged, 

 that of 8 being sinuate in profile view, slightly convex for the first 

 half, then still more slightly concave, becoming more strongly convex 

 and denticulated in the hindmost fourth ; that of 9 obtusely angulate 

 (about 150 °) at one-third length, remaining two-thirds very slightly 

 concave. 10 in dorsal view constricted in the middle, its posterior 

 margin wider than its anterior and very slightly and widely concave 

 medially. 



Superior appendages subequal in length to 10, blackish ; in dorsal 

 view nearly straight in the proximal three-fifths, strongly curved toward 

 each other in the remaining two-fifths, each decreasing gradually in 

 width to half its length ; apex somewhat obtuse, preceded on the inner 

 side by a distinct parallel finger-like tooth, which falls short of reaching 

 the level of the apex by more than its own length, no other tooth or 

 tubercle on the inner surface of the appendage ; in profile view each 

 superior appendage decreases in thickness from base to apex ; terminal 

 fourth curved downward ; apex moderately acute ; an obtusely pointed 

 superior tooth on the upper surface immediately after the base, and a 

 longer, flatter, rounded tubercle on the inferior surface, likewise im- 

 mediately after the base. 



Inferior appendage extremely short, not projecting caudad beyond 

 the level of the posterior dorsal margin of 10. 



Coxae and femora greenish or greenish-yellow ; tibiae and tarsi 

 brownish. 



Wings slightly clouded with pale brownish-yellow, especially in the 

 distal three-fifths ; stigma ochre ; veins, including the costa, brown or 

 black ; internal triangle of the hind wings free ; the other three triangles 

 two-celled. Front wings with 17-18 antenodals, 10-12 postnodals ; 

 and at most two rows of cells in Cu 2 area (= area be ween the inferior 

 sector of the triangle of Selys and the hind margin). Hind wings 

 with at most three rows of cells in the same area.
