136 Lloyd's natural history. 



Butterflies measure rather more than two inches in expanse, 

 and have rounded wings and slightly denticulated hind-wings. 

 The wings are smoky-brown, and the hind-wings have a bright 

 red marginal or sub-marginal band ; on the underside, which is 

 paler, the band is mixed with white, and there are some red 

 spots near the base. There are only a few species or varieties, 

 differing chiefly in the width of the red band. "The cater- 

 pillars much resemble those of Agerojiia, and the Butterflies 

 frequent waste ground on the borders of the forest, hovering 

 slowly over bushes." (Bafes.) 



Next to Didonis we may place Cystineura, Hiibner, a genus 

 with longer and narrower wings, but much smaller (expanding 

 about an inch and a half), and very differently coloured. The 

 species are black and white, or light brown and white, and 

 several are peculiar to the West Indies, while others inhabit 

 different parts of Southern and Central America. The prettiest 

 is C. dorcas (Fabricius), which is common in Jamaica, and is 

 of a pale orange-yellow. 



Vila, Ki.by, is another South American genus, closely 

 allied to the last. These Butterflies fly low, and hover over 

 the herbage in the forest with expanded wings. They are 

 about two inches in expanse, and are black, with very long 

 fore-wings, rounded at the tip, and are not unlike some of the 

 Ithomiince in shape, except that the wings, especially the hind 

 ones, are broader. They are black, with a white transverse 

 stripe near the base, and large white blotches on the fore- 

 wings ; on the under side there is a large white blotch on the 

 hind-wings also, and the dark portion of the wings is inter- 

 sected by tawny stripes. 



The genus Pyrrhogyra includes larger insects, measuring two 

 inches and upwards in expanse. The fore-wings are broad, 

 hardly longer than the hind-wings, with the hind-margin 

 slightly oblique. The '""ind-wings are long and broad, slightly
