band somewhat attenuate posteriorly ; in the cell the preapical band 

 subtriangular, sometimes not extended to the median vein ; the 

 terminal series of spots of the ground-colour linear as in hermocrates, 

 posteriorly these become lunular in shape. Hind wing : the 

 discal black band obsolescent, only faintly defined near costa 

 and at posterior end ; terminal black band and terminal lunules of 

 the ground-colour as in nomius but narrow ; grey subcaudal patch 

 as in nomius. Underside : similar to the underside in nomius with 

 the following exceptions the black markings of the upperside 

 entirely replaced by a bronze-brown : the discal series of red 

 spots are edged with black, and the outer edgings to the sub- 

 terminal series of white lunules are prominently and broadly 

 black.

<3 $ . Venation similar to that of the Glycerion group. Fore 

 wing : costa widely arched, apex produced, obtuse ; termen 

 straight or at the most slightly concave and sinuous ; tornus 

 rounded ; dorsum very short, not nearly one-half the length of 

 the costa, thus the wing forms a high and narrow triangle if the 

 dorsum is taken as the base. Hind wing : costa long, slightly 

 arched ; termen slightly scalloped, generally, but not in all the 

 forms, tailed at apex of vein 4 ; tail when present narrow, short, 

 scarcely spatulate, usually with a very slight upward curve ; dorsum 

 straight ; abdominal fold in the <S rather broad, with a well-marked 

 elongate tuft of scent-hairs. Antennae about half length of fore 

 wing, club well-marked.
