 subspecific rank. It differs from cuyabce type as follows : 



Superior abdominal appendages thicker, heavier, especially as seen 

 in profile view ; pale colors blue throughout instead of green ; mid- 

 dorsal thoracic carina reddish ; dorsal black on abdominal segment 2 

 narrowing anteriorly on the first third of the segment, but not pointed. 

 Abdomen 24, hind wing 17 mm. 



Habitat : — Brazil, Bom Fim, State of Bahia, Fazenda de Amaratu,

 (Plate V, fig. 83.) 



cJ 1 . Differs from cuyabce type in having the superior appendages 

 longer, distal portion not thicker than the middle, but tapering slightly 

 to the rounded apex, dorsal black on abdominal segment 1 not con- 

 stricted posteriorly, black of 2 forming a lance-head spot narrowing 

 anteriorly, but not pointed, and reaching the anterior end of the seg- 

 ment by a band the width of which is .2 mm. 10 postnodals on the 

 front wings ; 8 or 9 on the hind. Abdomen 27, hind wing 17.5 mm. ; 

 maximum height of abd. seg. 10 1.0 ; height of seg. 9 at base .92 mm.

This male approaches A. gracile la7icea Selys, but differs, so far as I 

 can judge from the descriptions of de Selys and Ris 19 and the latter's 

 figure of the appendages, in having the inferior appendages more 

 strongly curved upward, the superiors not reaching so high up on the 

 hind surface of the tenth segment, more constricted in their distal 

 half, (profile view), the tenth segment less elevated proportionally, 

 and the black on the dorsum of the second abdominal segment more 

 extended than de Selys describes for gracile lancea, viz.: "une tache 

 dorsaje noire en form de fer de lance appuyee sur le bord posterieur, 

 011 elle est un peu retrecie et formant une pointe anterieure s'arretant 

 a la moitie du segment, ou prolongee presque jusqu'a la base sur une 

 ligne tres-fine."
