GENUS EREBUS, 



Erebus^ Latreille, Consid. Generales, p. 365 (1810) ; Guenee, 

 Spec. Gen. Lepid. Noct. iii. p. 166 (1852); Walker, List 

 Lepid. Ins. Brit. Mus. xiv. p. 1289 (1858.) 

 This is another genus confined to tropical America and the 

 West Indies, and including only one or two large and bulky 

 species. The antennce are long and rather thick, and the 

 body very stout, but the abdomen is much shorter than the 

 hind-wings. The wings are dark brown, with black lines and 

 markings, and are very broad, with the hind-margins dentated. 

 The fore-wings are triangular, rather pointed at the tip, with 

 the hind-margin oblique ; the reniform stigma is represented by 

 an ocellated spot, and towards the anal angle of the hind-wings 

 is a peculiar mark, curved and rounded above, and trifid below. 

 The few species known of this genus are very similar, and have 

 been regarded by many authors as simply varieties of one 

 species.

This fine South American Moth varies much in size, some 



specimens expanding only three inches and a half, while others 



measure more than six inches. It is closely allied to Erebus 



odora (Linn.), and is perhaps not sufficiently distinct. The
