298 ON QUEENSLAND AND OTHER AUSTRALIAN LEPIDOPTERA, 



crenate line ; costa and inner margin darker suffused-grey : cilia 

 grey. Hind wings as fore wings, with basal half of inner margin 

 yellow : a wavy crenulate line from ^ costa to J inner margin, a 

 crenate sub-marginal finely defined black line, a suffused not 

 distinct line at \, and another suffused indistinct line before the 

 sub-marginal line — wing with dark suffusions toward base ; cilia 

 grey. Undersurface : forewings orange at base attenuated toward 

 apex beneath costa ; costa grey with black dots, a deep band of 

 black filling outer third of wing, with apex grey and cilia grey ; 

 and three or four small grey dots near inner margin ; a triangle of 

 white, subtended by costa, and upper half of black band, occupies 

 upper half of wing beneath costa and contains a deep black spot 

 near its base — between this and inner margin a triangle of smoky- 

 grey ; inner margin lighter grey. Hind wing orange in basal half, 

 outer half deep black bordered on either side with light-grey. 



Brisbane ; two specimens on trees. 



Allied to H. muscosaria ; but the sharp defined markings and 

 the orange of the body and hindwings readily distinguish it. 



Hypochroma diffundens, sp.nov. 



(J. 30 mm. Head, thorax, and abdomen smoky-grey. Antennas 

 black. Legs irrorated black and white. Forewings with costa 

 sinuous, apex acute, hindmargin crenulate ; grey with white scales 

 predominating near the centre, brown scales near the base, and 

 smoke-colour scales on hind border ; costa smoke-coloured, with 

 numerous minute grey and black dots: an indistinct grey trans- 

 verse line near base : a rich black line from J costa to \ inner 

 margin, curved outwards anteriorly and inwards posteriorly : 

 immediately beyond this is a smoke-colour line, then an elongated 

 linear discal spot, and again a tine rich black line from |- costa to 

 just before anal angle of inner margin, twice curved outwards and 

 dentate in centre : this line is bounded on outer edge by a fine 

 white line : a second dentate white line just beyond \ costa to half 

 way across wing, where it is submerged in a series of smoky-grey 

 spots, which extend from costa just beyond to anal angle of inner
