narrow stripe on the entire length of the second lateral thoracic 

 suture. Dorsum of abdominal segment 2 violet, bounded on each side 

 by a black stripe, which reaches from end to end of the segment and is 

 slightly widened at five-sixth's length and again narrowed to its hind 

 end ; the mid-dorsal violet at its widest is one and a half to two times 

 as wide as either lateral black stripe at the same level ; below this 

 black stripe each side of the segment is yellowish, or bluish, with an 

 oblique blackish stripe running forward from the hind margin as far as 

 the middle ; 3 is chiefly violet in dorsal view, with a narrow black 

 stripe on each side, beginning shortly behind the base and widening 

 on the hindmost fourth or fifth to meet its fellow of the opposite side 

 on the dorsum ; 4-7 black with some metallic reflection, each with a 

 narrow transverse basal pale ring, which on 4 is continuous with a 

 mid-dorsal longitudinal violet line or stripe reaching to two-thirds or 

 less of the segment's length ; 8 and 9 pale, violet or blue, with an 

 inferior black stripe on each side as long as the segments ; 10 black, its 

 hind edge narrowly pale, deeply emarginated mid-dorsally to half, or 

 nearly half, the segment's length, and produced backward over each 

 superior appendage as an acute process. Inferior lateral margins of 

 3-6 or 7 pale yellow, or blue, except in the hindmost sixth of each 

 segment. 



Stigma of the front wings surmounting less than one (78 per cent.), 

 one (11 per cent.) or more than one (11 per cent.) cell ; of the hind 

 wings surmounting less than one (72 per cent.) or one (28 percent.) 

 cell ; on all the wings the distal edge is more oblique than the proximal, 

 but more so on the hind pair. 



Antenodal cells on the front wings 3 (94.5 per cent.) or 2 (5.5 per 

 cent.); on the hind wings 3 (89 per cent.), 3 -f (5.5 per cent.), or 2 

 (5.5 percent.). 



M 2 (= nodal sector of de Selys) arising on the front wings nearest 

 the sixth (89 per cent.) or seventh (n per cent.) postnodal ; on the 

 hind wings nearest the fifth (89 per cent.), sixth (5.5 per cent.) or 

 midway between these two (5.5 percent.). (Percentages in these 

 three sentences based on the 9 cT from Chapada. )
