wards the terminal joint ; head black, with white spots ; pro- 

 thorax rufous ; thorax rufous ; abdomen black, Avhitish b(^- 

 neath : wings diaphanous, bordered with clear rufous ; m.-i- 

 vures and end of the cell of the anterior wings rufous ; space 

 between the median and submedian nervures of the anterior 

 wings and margin near the anal angle of the posterior wings 

 blackish : beneath as above, but margins paler ; costa of 

 posterior wings and spots at the apices of both wings pale 

 greyish : neuration of hind wings as in Ith. artena^ Hew, ; 

 lower discocellular bent to a right angle at the emission of 

 the recurrent nervule ; middle discocellular gradually curved 

 outwardly to meet the subcostal ; no upper discocellular, nor 

 upper radial. 



Hob. Oaxaca, Mexico. 



10. Ithomia simplex. 



^ . Exp. 2'15 in. Antennae black ; palpi white, black an- 

 teriorly ; head black, with white spots ; prothorax and thorax 

 greyish black ; abdomen black, whitish beneath : wings dia- 

 phanous ; nervures, a narrow line at the extremity of the cell 

 of the anterior wings, and a narrow margin round both wings 

 black ; subcostal to the end of the cell rufous ; a white oblong 

 spot close to the costa just beyond the end of the cell : beneath 

 as above, but with the markings rufous instead of black : 

 neuration of hind wing the same as in Ith. artena, Hew. ; 

 lower discocellular bent to a right angle close to the origin of 

 the lower radial ; middle discocellular gradually curved to 

 meet the subcostal ; upper discocellular entirely wanting, as 

 also the upper radial. 



$ . Like the <^ , but the margins rather more broadly black; 

 neuration of the hind wing like that of Ith. artena, Hew. ; 

 upper discocellular nervure absent ; upper radial leaves the 

 middle discocellular at its junction with the subcostal. 



Hab. Costa liica ((7ar?/^^o?). 



Ohs. Very nearly allied to Ith. a7-tena, differing chiefly in 

 the narrower borders to the wings and the smaller size of the 

 white spot on the anterior wings. 



11. Ithomia parva. 



(^ . Exp. 1*80 in. Antennae black; anterior wings diaphanous, 

 the end of the cell, the nervures, and the borders of the whole 

 of the wing-margins black ; next to the black spot at the end 

 of the cell is a white streak extending almost from the costa, 

 over the radials, nearly to the third median branch : posterior 

 wings diaphanous, the nervures and border of the outer margin 

 black ; beneath the markings are rufous instead of black, and
