BUTTERFLIES. 151 



and often of red spots near the borders of all the wings. This 

 genus, and all the following genera of the Erydnidce, are American. 

 The genus Mesosemia, Hiibn., is one of the easiest recognised 

 genera of this family, as well as one of the largest. The species 

 are brown or blue, and are generally striated with darker brown 

 and white or blue on the hind wings. The fore wings are some- 

 times marked with a white transverse bar ; but in almost every 

 species, a large round black eye, with two white pupils, and 

 surrounded by a pale ring, is situated near the middle of the fore 

 wings. 



SUB-FAMILY III. Euselasiince. 



Palpi of moderate length ; subcostal nervure, with from two 

 to four branches ; lower radial nervure emitted straight from the 

 subcostal, or connected with it by an oblique perfect discocellular 

 nervule. 



The typical genus Euselasia, Hiibn., includes a number of small 

 species, not much exceeding an inch in length, with short, rather 

 broad wings, and bright colours. They are blue, brown, orange, 

 tawny, or reddish, in various combinations, and the under surface 

 is generally more or less striated. Some species have a superficial 

 resemblance to other butterflies belonging to widely different 

 genera, such as Euptychia, and Theda, from which their structure 

 will at once distinguish them. 



SUB -FAMILY IV. Lemoniince. 



Palpi of moderate length ; subcostal nervure with three 

 branches ; lower radial nervure of both wings connected with the 

 subcostal at a right angle by a more or less rudimentary disco- 

 cellular nervule. 



Two-thirds of the family Lemoniidce belong to this sub-family, 

 which is divided into upwards of fifty genera, most of which are 

 of small extent. A few of the more interesting may here be 

 mentioned. 



The species of Lymnas, Blanch., are black or brown, with 

 rather large red spots near the base, on both sides of the wings, 

 and often with a yellow bar across the fore wings, and a yellow 

 border to the hind wings. 



Several very beautiful tailed species belong to the genus 

 Diorhina, Mor., and its allies. D. Hutes, Linn., is black, with
