AUTOMERIS. lOO 



This genus and its allies are very numerous in America, 

 though very few are met with north of the Tropics. The 

 wings are generally short and broad, rarely hooked, or con- 

 siderably dentated or subcaudate, and there is usually a large 

 round opaque eye-spot on the hind-wings only. The round 

 black spot which usually occupies the centre is sometimes 

 irregularly marked with white, or with some shade of grey. 



The larva is set with tufts of urticating prickles, and the 

 cocoon is 'formed between leaves.

The lo Moth is a common North American species. The 

 male expands two inches and a half, the female being some- 

 what larger. 



The antenUcX are yellow, as are also the head and thorax, 

 which are hairy. The fore-wings are yellow in the male, with 

 several waved, brown streaks ; they are reddish-brown in the 

 female, with three waved yellow lines, and several yellow streaks 

 placed close together near the centre. The hind-wings are 

 yellow, with a large black ocellus with an elongated white 

 centre. Beyond this ocellus is a semi-circular black band, and 

 beyond this, and parallel with it, is a ferruginous band which 

 is continued to the inner margin, which is also ferruginous.
