SUBFAMILIES. 1 



(1) Characters of family [see above] Heviileucinse. 



(2) Body email, abdomen short; hind wings large, vein II of fore wing not present; two distal ocelli: antennae plumose, 



no distal pectinations Pseudapheliinx. 



MOLIPPA Walker. 



[Molippa Walker, Cat. Lep. Het. Brit. Mus., VI (1855), p. 1345.] 

 [The type is }[. sabina Walker.] 



Imago. — <? , 9. Head with the front moderately wide; eyes moderately large. Antennae 

 of male much as in Dirphia, but a little shorter; joints moderately long; the pectinations as in 

 Dirphia; two pairs of pectinations to each joint, those of the distal pair shorter and situated 

 close to the basal ones, as in Dirphia; 9 antennas nearly simple; the joints about as long as 

 thick, the pectinations being represented by a group of about three setse on each side. Palpi 

 well developed, rather stout and blunt at the tips, porrect, extending out beyond the front, 

 being larger and more distinctly visible than in Dirphia. 



Thorax moderately thick, as in Dirphia, hirsute above, with darker, thick set long hairs. 



Fore wings longer, narrower, and more pointed in <? and 9 than in any species of Dirphia 

 known to me; subfalcate, costal edge considerably curved and the outer edge more oblique 

 than in Dirphia. Hind wings rounded, rather more so than in Dirphia, outer edge full and con- 

 vex; they reach end of abdomen. 



Abdomen distinctly banded with black and yellow ochre. 



Markings much as in some species of Dirphia. There is no distinct discal mark, but a 

 large irregular dark scalloped loose ring, and on the hind wings a somewhat oblong dark smoky 

 discoloration. The extradiscal line scalloped; the basal one obscure; there are two smoky 

 black lines on the hind wings. 



This genus differs from Dirphia in having larger and somewhat longer palpi, shorter anten- 

 na?, while the fore wings are longer, narrower, and more pointed. In Dirphia there is either a 

 small white discal spot or none at all, while hi the present genus there is an irregular discal 

 ring. There are no vestiges of pectinations on the 9 antennas, their place being taken by a 

 group of cilia, a rather rare feature in this family. 



MOLIPPA SABINA Walker. 



Plate xlii, fig. C. 

 [Molippa sabina Walker, Cat. Lep. Het. Brit. Mus., VI (1855), p. 1345.] 



Imago. — Two <? , one 9 . Head, thorax, and wings ashy fulvous or tawny, with a generally 

 faded hue. Thorax with scattered long black subclavate hairs, which are more numerous in 

 9 than s. 



Fore wings with a broad diffuse longitudinal shade at base behind the costal region, extend- 

 ing out to the submarginal line. Traces of three basal lines on the costal edge. Discal spot 

 a large smoky brown irregular ring forming three scallops on the outer edge, the points or apices 

 of the scallops resting on the veins; a median line within the ring extends along the discal veins. 

 Extradiscal line double, dark, regularly scalloped, beginning on the outer one-fourth of the inner 

 edge and ending on the outer one-fifth of the costa, next to a subapical distinct dark brown 

 costal patch, which on the costa extends nearly to the apex. An obscure irregularly scalloped 

 submarginal line, beyond which the edge of the wing is dull, but uniformly tawny. Fringe 

 on both wings short, white at the ends of the veins, black between. Hind wings clearer and 

 paler on the inner two-thirds, discal spot narrow long, blackish. A distinct extradiscal smoky 

 black line, and beyond is another about twice as wide, scalloped on the outer edge; beyond 

 this line the outer edge is dusky tawny, while the veins are ochre yellow. Wings beneath 

 uniformly paler than above, and with the markings less distinct and the discal rings obsolete. 

 At the base of the fore wings is a black patch which extends to the eyes. 



Abdomen with distinct black and orange-ochreous rings of the same width, with a few 

 long scattered pale hairs arising from the orange bands or rings.
