the mesepisternum, narrowly bordered along its outer edge with brown 

 which fades into the pale but ill-defined antehumeral stripe ; side of thorax 

 as in the male, but the metinfraepisternum is entirely black except the 

 lower nearly equilaterally triangular part. Metastemum as in the male 

 but the lateral dark areas are larger and are black. 



Mesostigmal lamina as in the male. 



Coxae and legs similar to those of the male. 



Venation similar to that of the male, the stigma slightly duller, less 

 reddish, brown. 



Abdomen seen from above : 1-5 similar to those of the male, but darker, 

 the pale basal rings are as distinct as in the male but the anteapical pale 

 area on each segment is less distinct, especially on the posterior segments, 

 though the apical black, as distinguished from the color basal to it, is dis- 

 tinct in all; 6 and 7 brown, pale ringed at base, and very slightly darker 

 at apex; 8 and 10 black; 9 distinctly patterned, slightly more than the 

 basal half pale (blue?) with a black median longitudinal bar from the 

 base passing into the black which occupies the apical part of the segment ; 

 this black bar is about .4 wide at the base and about .7 wide where it passes 

 into the apical black. Seen from the side 1-5 are similar to those of the 

 male ; 6 brown, pale basally and thence along the ventral margin for a 

 short distance, and with ill defined traces of pale on the ventral margin 

 at the region of the anteapical pale area ; 7 brown, darker at the postero- 

 ventral angle; 8 and 10 black, the ventral margin of 8 pale, widest at the 

 base and tapering apically, not quite reaching the apex; 9 pale (blue?) 

 with a triangular black area in the antero-ventral angle and with apical 

 black, narrowing from the dorsum to the extreme postero-ventral angle, the 

 black at base and the black at apex with their opposing lines parallel, that 

 is, the pale area cuts diagonally across the segment. Sternum of 1 pale; 

 2-5 dark to black, pale at base and anteapically ; 6 similar to the preced- 

 ing segments but apparently lacking the anteapical interruption; 7 black, 

 pale at base and extreme apex; 8 blue with a small median longitudinal 

 dark area which reaches neither base nor apex, and is widest at mid-length. 

 Appendages black, shaped like those of magdalenae. Valvular styles at 

 their point of attachment slightly distal to the level of the apex of 10. 



VeTiatkmal characters based on two males and one female 



Postnodals front wing, 12 (25% males), 13 (50% males), or 14 (25% 

 males, 100% females) ; hind wing, 11 (50% males), 12 (25% males), or 

 13 (25% males, 100% females). 



M3 in front wing arising between the first and second postnodals (100% 

 males, 100% females) ; in the hind wing at the first postnodal (25% males, 

 100% females), or between the first and second postnodals (75% males). 



Rs in front wing arising at the seventh postnodal (50% males), at the 

 eighth postnodal (25% males, 100% females), or at the ninth postnodal 

 (25% males) ; in the hind wing at the seventh postnodal (100% males, 

 100% females).
