apex black, unusually long and slender for the genus ; tibiae 

 and tarsi black; third tibia longer than the tarsus and claws. 

 The Chapada female, discussed below, has the legs incomplete 

 but apparently similar. 



Wings hyaline to more rarely smoky tinged especially about 

 the nervules, no trace of any distinct colored area. Costa dark. 

 The venational characters of 25 male wings and 6 female wings 

 were tabulated with the following result: triangle front wing 

 free, 16% male, 0% female ; crossed 84% male, 100% female ; 

 subtriangle front wing crossed, 100% male, 100% female ; tri- 

 angle hind wing crossed, 100% male, 100% female: subtrian- 

 gle hind wing free, 32% male, 0% female; crossed, 68% male, 

 100% female : anal field front wing one cell wide, 100% male, 

 100% female : three postanal cells in the proximal row, 100% 

 male, 100% female : two postanal cells in the distal row, 68% 

 male, 33 1/3% female; three in the distal row, 32% male, 

 66 2/3% female. 



Male. — Abdominal segment 2 with a narrow longitudinal 

 dorsal pale greenish stripe the length of the segment, separated 

 from the extensive pale lateral areas ; 3 similarly patterned, the 

 dorsal stripe becoming very narrow apically but reaching near- 

 ly or quite to the apex, and the lateral pale area confined to the 

 basal third of the segment; on 4 the apical extension of the 

 dorsal stripe and the lateral area is still more reduced, the 

 areas joining more or less basally to form a ring, and the 

 thread-like extension of the dorsal stripe extending about four- 

 fifths the length of the segment or less; on 5 and 6 the dorsal 

 pale stripe is not evident, but the basal lateral areas are nearly 

 or quite united in the mid-dorsal line to form a narrow trans- 

 verse basal ring on each segment; 7-10 and appendages as de- 

 scribed by de Selys, the basal ring on 7 apparently greenish, 

 the lateral stripe on 8 yellowish and really better described
