ARCTIIDAE AND CTENUCHIDAE FORMERLY IN AUTOMOLIS 23 



Probably most easily confused with the few specimens of dolens in which the 

 outer marginal connection between the distal yellow fascia and the tornal indentation 

 has been lost. However, the yellow tornal marking is apparently never digitate 

 in dolens, but is distinctly so in most specimens of zonana. In ab. incompleta 

 Seitz (1922 : 373) the yellow tornal marking is unusually narrow. The shape of 

 the uncus and the presence of a short tooth at the apex of the valve serve to 

 distinguish zonana from both flavicinda and dolens.

<$. Palps dark brown. Head iridescent brown and greenish blue. Patagia brown along 

 anterior margin, otherwise yellow. Tegulae yellow anterior to costa of forewing; rest of 

 tegulae and remainder of dorsal surface of thorax greyish brown with weak greenish blue 

 iridescence. Sternal and pleural regions of thorax brown with greenish blue iridescence; legs 

 similarly coloured but with weaker iridescence. Upper surface of forewing greyish brown 

 (brownish grey - 4D2 - in fresh material); palest posteriorly, distal to basal yellow, transverse 

 fascia; apical (distal) transverse fascia present in most specimens examined, but absent in 

 type of schistaceus, its paralectotype and 14 other specimens from Venezuela; this apical 

 fascia broadest in type of ardesiaca and the remaining specimens from Costa Rica - in these 

 specimens the width of this fascia is greater than the distance between apex of wing and distal 

 margin of the apical fascia; the basal fascia also is wider in the Costa Rican specimens. Upper 

 surface of hindwing dark brown distally, yellow proximally. Under surface of wings as for 

 upper surface except that brown areas are uniformly dark brown and that basal area of wing 

 (proximal to yellow basal fascia) is dark brown anteriorly but yellow posteriorly. Dorsal 

 surface of abdominal segment 1 yellow; 2-4 dark brown and iridescent greenish blue, 5-7 

 similar but grey medially (the grey area broadest on 7) ; 8 dark brown and iridescent greenish 

 blue laterally, grey medially with pair of white spots on anterior margin. Ventral surface of 

 segment 2 dark brown and iridescent bluish green with yellow medial patch at posterior margin; 

 3-8 similar in ground-colour, 3-6 with broad yellow medial area, 7 with small yellow medial 

 patch, 8 unmarked. 



$. As for male, but brown, distal band of hindwing much broader than yellow, proximal 

 band.
