ITHOMIA. 31 



This typical genus of the IthomiincB probably comprises 

 (with a few lately separated from it) about 200 species, and is 

 the most extensive of the sub-family. A great number are 

 more or less transparent, though some are opaque. The front 

 legs of the males are reduced to a mere knob, the tarsi of the 

 females are five-jointed, and the lower disco-cellular nervule of 

 the hind-wings forms an acute or right angle with the median 

 nervure, instead of an obtuse one. 



The type is 



ITHOMIA DOTO. 



A r ereis vitrca doio, Hiibner, Samml. Exot. Schmett., i., pi. 1 



(1S06). 

 Itliomia doio, Hiibn., I.e. text (1822 ?). 



A yellowish-hyaline species, with narrower wings than 

 I. flora (Cramer). It has narrow black borders, and black 

 nervures ; there is an orange-tawny stripe on the fore-wings 

 below the narrow costal border, and another above the inner- 

 marginal border ; and a sub-marginal orange-tawny band on 

 the hind-wings, narrowly edged on both sides with black. It 

 is a native of the Lower Amazons. 



Dr. Scudder rightly, as we think, regards this species as the 

 type of the genus, being the only one described by Hiibner 

 as an Ithomia in the fragmentary text to his " Sammlung." 

 Other authors, however, select the following species, the first of 

 four (of which /. doto is the third) included under Ithomia by 

 Hiibner in his " Verzeichniss."
