ARCTIID.T:. 1 15 



This species comes from Brazil, and expands about i j/ inch. 



" Male. — Greenish-blue. Head and thorax with an aeneous 

 tinge. Palpi short, slender, decumbent j third joint minute, 

 lanceolate. Antennae moderately pectinated. Abdomen extend- 

 ing rather beyond the hind-wings; sexualia very small. Legs 

 smooth ; spurs short. Fore-wings rather narrow, rounded at 

 the tips, obliquely tinged with aeneous at the base and about 

 the tips. Hind-wings black, whitish along the cosla, hardly 

 more than half the length of the fore- wings ; a broad crimson 

 lanceolate streak extending from the disc to the exterior border, 

 which is also crimson." ( JValker.) 



FAMHA' XHI. ARCTHD.^. 



Egg.— Smooth, globular. 



Larva. — Clothed with long shaggy hair, or tufted; sixteen 

 legs ; generally feeding on low plants. 



Pupa. — Enclosed in a cocoon. 



Imago. — \Vith ocelli ; the antcnnce sometimes pectinated in 

 the male, liody stout, rather short, more or less hairy; collar 

 well developed. Wings generally brightly coloured and en- 

 tire. On the fore-win^^^s the lowest discoidal nervule is generally 

 stalked with the upper median nervule, making the median ner- 

 vule appear to be four-branched ; and on the hind-wings the 

 costal nervure, which in the Zy<^iefiiJL^ is often practically non- 

 existent, is thrown off from the sub-costal considerably before 

 the cell. The fore-wings are generally oval, and the hind-wing-^ 

 rounded. 'Die hind-wings are sometimes lobate, but nevtr 

 tailed, and have usually two sub-median nervures. In one 

 or two genera the wings of the female are more or less rudi- 

 mentary. Some species fly by day. 



The Tiger Moths may be divided into several Sub families, 

 which I will nf)w discuss more in detail.
