SUB-FAMILY III. LEMONIIN^E. 



■Egg. — Deeply reticulated and filamentosed. 



Larva. — More or less cylindrical, fasciculate. 



Pupa. — Attached by the tail, and sometimes also by a girth 

 round the middle of the body. 



Imago. — Wings generally short and rounded; occasionally the 

 fore-wings are rather long or pointed, and the hind wings are 

 sometimes dentated, or, if long, are frequently tailed. Wings 

 very various in colour (rarely vitreous), and with no characteristic 

 patterns except within generic limits. Fore-wings with the sub- 

 costal nervure four-branched, except in a few genera, most of 

 which used to be classed with the Nemeobiince. {Eurybia, Meso- 

 semia, &c.), and in Isapsis, in which it is three-branched. 

 (This character, however, is not constant, for Mesosefnia has 

 the sub-costal nervure four-branched in some species.) Disco- 

 cellular nervules generally more or less imperfectly developed. 

 Hind-wings with the basal nervure well developed. 



Range. — This extensive group is entirely confined to Tropical 

 America, with the exception of a very few species which are met 

 with in the United States, or which extend beyon-d the Tropical 

 portions of South America. 



Note. — The species of this Sub-family have been divided in'.o sub- 

 ordinate groups by Schatz and Rober, according to the number and posi- 

 tion of the branches of the sub-costal nervure and other characters of minor 

 importance. But with the exception of Stalachtis, which seems t© be suffi- 

 ciently distinct to be reinstated as a Sub-family, into which it was originally 

 formed by Bates, we are not inclined to regard these distinctions as of special 

 importance. Even the number of sub-costal branches is not always constant 

 in the larger genera. 



The Lemoniince are very numerous and dissimilar, and we 

 cannot attempt to do more than discuss a limited number of 

 the most important and characteristic genera. Some of the
