usually dai-k- fuscous posteriorly; tuft ochreous or wbitish-ochreous sometimes 

 fuscous towards apex. Legs ochreous; anterior pair and all tarsi sometimes 

 fuscous. Forewings triangular, eosta straight, apex rounded, termen bowed, 

 moderately oblique; ochreous or wbitish-ochreous, sometimes almost wholly suf- 

 fused with fuscous; four transverse dark-fuseous lines, rarely obsolete and in- 

 dicated in dark-ochreous only; first from one-sixth costa to one-fourth dorsum, 

 second from two-fifths costa to near mid-dorsum, third from four-fifths costa to 

 three-fourths dorsum, slightly bisinuate, fourth subterminal and usually con- 

 nected with termen on veins, leaving a terminal series of ochreous or whitish 

 spots; base and median area often fuscous; two, circular, orange, subcostal spots 

 before and after middle; cilia ochreous sometimes mixed with fuscous. Hind- 

 wings with termen rounded; ochreous, more or less suffused with dark-fuscous, 

 sometimes wholly so except at base; cilia as forewing's. 



$. 56-68 mm. Forewings pale-ochreous or white; lines nsually narrower 

 and not suffused; discal spots usually absent. Hindwing's wholly ochreous, or 

 with suffused median and terminal bands, or wholly dark-fuscous. 



Very variable in both sexes.

Palpi obsolete. Posterior tibiae without middle spurs. Forewings with 5 

 usually from well above middle of cell, but sometimes from middle, 6 from 

 upper angle of cell or from areole, 7, 8, 9, 10 stalked, or 7 and 10 from end 

 of areole, areole rather small and narrow, 11 from near end of cell or from 

 two-thirds. Hindwings with 3 and 4 separate or approximated at base, 5 from 

 slightly above middle of cell, 6 and 7 stalked, 12 anastomosing or connected 

 with cell at one-fourth or one-third. 



'I'here is considerable variability in the neuratiou. In one <S the areole is 

 open on both forewings from absence of the inter-radial an-astomosis. The genus 

 contains only one species.

c?. 40-60 mm. 9. 52-70 mm. Head fuscous or oehreous-brown, rarely in 

 c? whitish. Antennae pale-fuscous or pale-ochreous. Thorax fuscous-brown or 

 ochreous-brown, tips of hairs often whitish, rarely wholly whitish in c?. Abdo- 

 men brownish-orange; bases of segments usually fuscous; tuft whitish or oehreous- 

 whitish. Legs fuscous or brownish-ochreous. Forewings elongate-triangular, 

 eosta straight, apex rounded, termen slightly bowed, slightly oblique; fuscous- 

 brown or ochreous-brown; a small, white, median, transverse discal mark, rarely 

 obsolete; a fuscous line from three-fourths eosta to dorsum between three-fifths 

 and four-fifths, at first outwardly rounded, then sinuate, usually faint, some- 

 times very distinct, in ? often obsolete; sometimes in c? there are broad longi- 

 tudinal white lines variably developed, first along eosta, second from discal mark 

 to termen, third along fold curving downwards to tornus; in some examples the 

 white markings are extensively suffused, and in these there may be incomplete
