EUPHANESSA » nov. gen. 



The head is much elevated behind the antennse, the epicranium 

 divided on its surface into two bosses. Clypeus much elevated, surface 

 convex. The front narrows rather rapidly anteriorly. Antennae simple 

 scaled above and on the sides, setose beneath. Palpi porrect, passing 

 nearly one-half their length beyond the front. Primaries two-thirds 

 as broad as long; costa rounded towards the apex. Outer margin 

 oblique, almost as long as the inner margin. Internal angle rounded. 

 Costal nervure bent down towards the subcostal, parallel at its termina- 

 tion with the three s. costal nervules. A scalene triangular area below 

 the s. costal; one of the two shorter sides of which consists of the com- 

 mon base of the 4th and 5th s. costal ; the other, by the anastomosis 

 of the 4th s. costal with its main nervure. The 1st median becomes 

 independent, arising from the middle of the discoidal area. 



Secondaries nearly as large as the primaries, very broad. Outer 

 margin full rounded; internal angle about midway in the wing, the 

 internal edge being short. Scales minute, thin, wings semi-transparent 

 in spots. 



This genus differs from Nudaria with which it has been confounded 

 by Walker and subsequent writers, in the smooth finely scaled narrower 

 front, while the antennae are not tufted at the base as in the European 

 genus. Besides, the palpi are much longer, and project far beyond 

 the front ; the triangular fore-wings are much broader and they have 

 straighter costae than in Nudaria. In the last named genus also, the 

 inner edge is warlij twice as long as the outer, while in Euphanessa it 

 is considerably shorter than the outer edge. The secondaries in our 

 genus reach much farther beyond the tip of the abdomen. There are 

 moreover constant differences in the neuration of the two genera.
