Forelegs (fig. 181) without epiphysis; first tarsal segment long, 

 approximately 3x length of second. Middle and hindtibiae usually 

 with prominent apical spur, sometimes unarmed (A. seitzi) ; first tarsal 

 segment of these legs doubling second in length. Abdomen usually 

 surpassing hindmargin of secondaries by nearly half its length. 



Wings (fig. 165) largely free of scales, transparent. Primaries 

 elongate, tornus usually indistinct or absent; outer margin strongly 

 oblique, as long or longer than hindmargin; either 9- or 10-veined; 

 Ri and 2 very short, usually fused, sometimes dividing just before 

 margin ; R3 and 4 either fused or separate, R.5 connate at base ; discal 

 cell prominent, very near costal margin; base of medius undivided 

 within cell of both wings; M2 and 3 completely fused, occasionally 

 connate with Cui; base of lA usually atrophied, outer third curving 

 down to fuse with 2A; 2 A strongly angulate at juncture of lA; 2 A and 

 3A separate at extreme base, then fusing with short spur sometimes 

 given off toward hind margin. Secondaries slender in outline, termen 

 strongly rounded ; usually with 6, sometimes 5, veins {A. seitzi) ; all veins 

 arising separate from cell; Sc+Ri and Rs separate at base, fusing 

 midway along cell, usually continuing as one vein to margin ; M2 and 3 

 fused. 



Male genitalia. — Elongate. Apex of tegumen not extended, 

 usually bluntly triangular. Valves with pul villi slightly developed; 

 tip of sacculus with usually two minute spines. Vinculum relatively 

 slender, approximately 2x as long as wide. Saccus well developed, 

 rodlike. Aedeagus base sometimes slightly enlarged. Eighth sternite 

 with furcations long, slender; undivided base weak with only a narrow 

 bridge connecting two furcations. 



Female. — Unknown.
