than the Brazilian ones, and generally much paler in colour, though one of my six 

 Venezuela ones is the darkest 1 have ever seen ; the expanse of the two largest 

 is 7 inches = 178-5 millim. 



MEGANOTON. 

 Here 1 have four species new to science to describe. 



Meganoton cocytioides sp. nov. 



This is the largest of the genus, and curiously like a Cocj/lius in its markings. 



Forewings clay brown, powdered with grey scales, giving the wings a marbled 

 appearance. 



There is a very large white stigma with a black ring rouiid it in the cell, and 

 joined to the costa by a very broad and short ohlique black band. On the outer 

 edge of the cell is a black spot. From the costa, a fourth from the ape.\, 

 springs a broad, heavy black band, which boldly curves round into the wing and 

 with its other extremity joins the apex. Between this band and the cell the 

 forewings are crossed transversely by four indistinct bands of brownish, half- 

 moon shaped spots ; from the apex to the angle of the inner margin there extends 

 a submargiual row of black spots. On the disc of the wings the two central 

 longitudinal lines, so characteristic of the genus, are increased to an enormous 

 size and are extremely broad. 



HiruJwimjH blackish brown, base deep grey, abdominal margin very broad 

 and pale grey. There is an indistinct pale band across the disc of wings, starting 

 from the anal angle. 



Head and protkorax brownish. 



Thorax in the centre brownish red, sides velvety black, with a white band 

 at the base of the wings and a dark grey band separating the red centre from 

 the black. 



Abdomen greyish brown on the dorsal surface with a narrow black line down . 

 the centre. On each side is a broad and heavy black longitudinal band, and below 

 this, on each side of the first four abdominal segments, are round cream-coloured 

 patches set in a black ring, exactly as in Coo/tiiis cluentius of Cramer. 



Underside uniform brown, with whitish yellow fringes, a dash of white near 

 the base of the hindwings, and basal two-thirds of inner margin of forewings buff. 



Body snow white. 



Expanse: male, n-5 inches = 14U-25 millim.; female, 7 inches = i7S'5 

 millim. 



Uab. Fort Mackay, Queensland. 



Meganoton distinctum sp. nov. 

 (PI. VII., fig. 19.) 



Foretvings silvery grey with faint and slightly darker cloudings. From the 

 apex obliquely to the outer edge of the cell there e.\tends a slightly zigzag black 

 line. Within the cell is an indistinct round dark grey stigma. 



Hindwings dark blackish brown, fading into silvery grey on the [lortion nearest 

 the anal angle. The fringes on fore- and hindwings are evenly and alternatel)- 

 streaked black and white. 



Head, thorax, and abdomen silvery grej'. 



Expanse, 4-.5 inches = 114'To millim.
