dark brown, reddish in front and below. Primaries below with

 a large marginal lilacine crescent at the apical sinus ; a broad 

 discal band as above, but scarlet changing to saffron-yellow ; 

 a bifid spot of the same colour below the cell ; discoidal cell 

 mustard-yellow, enclosing two black-edged white dots; interno- 

 median area greyish brown, becoming blackish at the borders 

 of the discal band ; a large black spot with cuneiform white 

 centre at the end of the cell : secondaries ferruginous, irregu- 

 larly banded and striated with deeper colour; a squaraose 

 transverse yellow streak enclosing a reniform spot across the 

 end of the cell ; three black spots near the base ; tips of the

Yokohama [Jonas). 



One of the most beautiful moths yet discovered ; the female 

 is rather smaller and paler below, the body and secondaries 

 being yellowish.

PSYCHOGOES, n. gen. 



Allied to Secusio {8. annulata), the primaries considerably 

 broader, with the discoidal cell shorter, the subcostals united 

 at the base^ so as to form two prajdiscoidal cellules, from the 

 second of which the true brandies are emitted, the first 

 branch simple, the second trifurcate, a third branch (the con- 

 tinuation of the main subcostal nervure) emitted from the 

 supero-exterior angle of the cell; the radial emitting a recurrent 

 false vein backwards through the cell to the base ; neuration 

 of secondaries almost as in Secusio ; body rather more slender ; 

 palpi extremely short, barely extending beyond the front of 

 the head ; antennae slender, with very short pectinations. 



Type F. aterrima. 



24. PsychofjGes aterrima^ n. sp. 



Shining black, the primaries with an oblique narrow snow- 

 white band, abruptly and transversely cut off on the median 

 interspaces ; secondaries with the fringe snow-white ; prima- 

 ries below with the basal area greyish, the white band extended 

 downwards towards the external angle ; secondaries greyish 

 towards the base, the abdominal margin grey; an angukted 

 central grey line, dotted with white below the middle ; fringe 

 white ; body below grey, the legs and abdomen banded with 

 white. Expanse 1 inch 7 lines.
