48 LLOYD'S NATURAL HISTORY.

This species is common in Mexico and Central America, 

 and may be known by having no green lines beyond the 

 broadest band of the fore-wings, which is only slightly bifid. 

 On the hind-wings the tail is black, slightly bordered with 

 white, and there are no conspicuous green markings within 

 the interrupted sub-marginal series. 



This species is remarkable for its migratory habits. It is 

 described as migrating in vast flocks, flying at a great height 

 by day, from north to south, or from east to west. The exact 

 seasons, direction, starting-points, and goals of these migra- 

 tions have not yet been fully worked out. The Moths also 

 fly by night, and Mr. Champion describes them as attracted 

 by light, and as settling with outspread wings on white walls 

 in the city of Mexico, about two or three o'clock in the 

 morning.

This species, which is confined to the island of Jamaica, is 

 one of the smallest of the genus, the largest specimens not 

 exceeding three inches in expanse. Both the fore- and hind- 

 wings are rather long and narrow, and the green bands are 

 more or less strongly suffused with reddish-copper, especially 

 on the under surface. The central band of the fore-wings is 

 rather narrow, and there are one or two green lines between 

 it and the tip. On the hind-wings, the green bands are con- 

 fluent.
