New Genera and Species of North American Moths. 



By Henry Edwards. 



Family HETEROGYNIDiE, H.-Sch. 



Thia, new genus. 



Size small. Tliorax and abdomen rather stout, the latter extending for nearly 

 lialf its length behind the posterior wings. Head imbedded deeply between the eyes, 

 which are rather large. Palpi long, slightly bent downwards, the basal article longer 

 than the other two, the apical short, pointed. Antennre simple. Tibiiv and tarsi 

 long, hind tihite with two long spines, the tarsi also furnished with short spines and 

 the last joint sharply hooked. (The middle and anterior pair aie ijroUen in the ^pe- 

 cimen belore me.) Wings short, the anterior pair only slight'y longer than the 

 ])osterior. The margins of both are \ery distinctly rounded. Fringes long. The 

 wings are densely covered with scales, so that it is imposible to give tlie neuration 

 accurately. There is, however, apparently no coital vein to the inlerior wings, and 

 the internal vein seems to be very shoi t. 



I have no doubt whatever of the close relationsliip of this singuiar 

 form to the European genus Atychia, Latr. , wliich has until recently 

 wanted a permanent resting-place. It has been placed in the TortricidiB, 

 Tinculw, and I think by one author in the Li/Jiosudce, but it is now by 

 I ommon consent agreed to belong to H.-Schi.tffer's family Heterogynidde, 

 which comes in the system near to the ^geriad>.e and Thyridi.c. My 

 Peut/iefn'a parvida may also be placed into H.-Schaefier's family, so that the 

 present species will be the second of the group now Unown in N. Ameiica. 

 Thia is the Goddess of Light of the Cireek Mythology. 



Thia extranea, n. sp. 



Head, thorax, abdomen above and below, and upper surface of primaries greenish 

 black, with slight metallic lustre. Fringe slightly golden. Secondarie-: sub-diaphanous, 

 with the fringe golden Ijrown, with golden scales scattered over the surface. Tlic
