only slightly marked, hut a hioad straight deep brown central line is conspicuous just 

 beyond the discal dot ; tlie apical black jiatch is strongly marked ; and beyond the 

 exterior line of both wings below the median is a round black blotch. This aberra- 

 tion is a development of that described by me as nubilosa from Fergusson Island.

The other form is as inconspicuous as tetrasp'da is striking. Both wings are dull 

 fawn-colour, speckled with dark fuscous dots, with no markings except the black 

 cell-spots, and in the forewings some brown interrujited spots indicating the exterior 

 line towards the costa. The short dark lines on the inner margin of hindwings above 

 the anal angle are present, but very inconspicuous. 



The two examples were taken in September and October 18U3. 



Ischalis Wlk. XXVI. p. 1750. 



S. Forewings : with costa shouldered at base, then straiglit, with a faint 

 in.sinuation, to apex ; apex shortly produced ; hindmargin toothed at veins 4 and (i, 

 indented between, oblique below the lower tooth to anal angle, but with a slighter 

 tooth at vein 3. 



HindiviiKjs : with hindmargin rounded. 



In the ¥ the hindmargin of hindwings is quite as strongly dentate as in fore- 

 wings. 



Palpi porrect, i-ather long ; forehead tufted ; antennae lamellate, thickened 

 towards base, subserrate ; alidomen of J \ery long ; inner half of hindwings of S 

 beneath clothed thickly with long furry hair. 



Xeuration : forewings, cell two-thirds of wing ; the median and subcostal vein.s 

 both bent inwards at extremity ; first median, at three-fourths, second before end, 

 third from end of cell ; radials normal ; last three subcostals stalked, second 

 anastomosing with the stem of third and fourth towards apex, forming a very long 

 areole ; all three then separating together ; first subcostal free. 



I have given this diagnosis of Ischalis here because Walker, who described the 

 type-species twice, first as Selenia tjaUnria and afterwards as Ischalis thernto- 

 chronvitn, had only ? ?, while 3Ir. Meyrick, who described the genus afresh under 

 the name of Stratocleis, did not describe or notice apparently the peculiarity of the 

 underside of the S hindwing. It is almcst certain, judging from the description, that 

 Guen^e's Epioiie incana is the same species, although he gives Tasmania, perhaps 

 by an oversight, as habitat. 



HOO. Omiza columbaris sp. nov. 



Foreiolmjs : pale lilac-grey, with very fine dark transverse striae; tlie lines 

 purple ; first from costa at two-fifths to inner margin at one-fourth, slightly curved ; 

 second from costa at four-fifths, acutelv angled below ajiex, then faintly curved 

 to inner margin before middle, the interval between the two lines there being 

 narrow ; this space is filled in with deep green ; discocellular edged with purple ; 

 a flattened pale grey costal spot liefore apex; fringe rufous. 



Hindiv-infjs : with costal area [lale ; the basal one-third rufous olive, edged by a 

 straight purpli.sh line ; fringe and hindmargin rufous.
