 with yellowish especially on veins and margins. Underparts 

 stramineous. Hypopygium: Upper posterior angle rounded, hind 

 margin nearly straight, lower angle slightl}^ produced, black-tipped, 

 the lower margin a little sinuate anterior to the tooth. Outer claspers 

 gradually narrowed from base for three-fourths of their length, 

 then abruptly, the apex compressed, black-margined, the tip rounded 

 as seen from side. Inner claspers slender, rather straight for basal 

 three-fourths, then outcurved and aciculate. Aedeagus three-parted 

 from base, the lateral processes somewhat longer than the central 

 one, acuminate apically, the central shaft slightl)'^ bifid and two- 

 pointed (fig. 67).

Male. — Body whitish to pale yellowish above and below, tegmina 

 nearly hyaline, apical cells sometimes slightly fumose. Hypopy- 

 gium : Upper posterior angle of 9th segment rounded off, lower 

 developed as a short, blunt, downwardly projecting tooth (fig. 70). 

 Outer claspers gradually narrowed on basal two-thirds, more decid- 

 edly on apical third, apex somewhat spatulate and heavily pig- 

 mented; a line of short bristles on upper edge of outer clasper, and 

 longer hairs along posterior margin of 9th segment, above tooth, in 

 region of articulation of outer clasper, and on anal tube. Inner 

 clasper slender, curved outwardly, most so near apex, which is 

 aciculate. Aedeagus three-parted almost from base, the lateral proc- 

 esses extending nearly as far posteriorly as the central one, each 

 lateral process shaped somewhat like the letter L, the shorter arm 

 projecting laterally as seen from above and abruptly angulate 

 apically; tip of central process bifid, the divisions tapering rapidly, 

 curving outward and backward, and sharp-pointed (figs. 68—69).
