ON NEW AND INSUFFICIENTLY KNOAVN INDO-AUSTRALIAN 



GEOMETRIDAE. 



By LOUIS B. PEOUT, F.E.S. 



SuBFAM. OENOCHROMINAE. 

 1. Celerena angustisignata spec. nov. 



?, 60-62 mm. Head yellow. Terminal joint of palpus rather short, black. 

 Thorax and abdomen concoloroiis with wings, front of thorax more orange. 



Forezving deep chrome or cadmium yellow ; proximal third of costal margin 

 slate-grey, black at extreme base and very narrowly along costal edge ; a 

 narrow slate-grey, distally black-edged band arising at the end of this grey 

 shading, running at first in the direction of tomus or hinder end of termen, but 

 curving very slightly in the end of the cell, interrupted at the fold 6 or 7 mm. 

 from termen, reappearing merely as some feeble grey shading at and behind 

 SM' ; distal border slate-grey, najrrowly edged proximally (except at extreme 

 posterior end) with black ; 8 or 9 mm. wide at costa, narrowing rapidly to R' 

 (where it is about 3 mm. wjde), then more gradually (scarcely 1 mm. at tomus). 



Hindwing with the slate-grej' border quite narrow throughout, its black 



proximal edging thick anteriorly', tapering posteriorly. 



Underside with the markings mainly black ; apex of forewing and fringes 

 greyer ; proximal band of forewing broadened and rather diffuse. 



Sudest Island, January — February 1916 (type) and March 1916, Mount 

 Riu, 2,000 feet (paratype) ; both in coll. Tring Museum, collected by Eichhom 

 brothers. 



Perhaps a local form of prodroma Meyr. or probola Prout (Nov. Zool. 

 xxiii. 5). In any case it will require a name. 



SuBFAM. HEMITHEINAE. 

 2. Hypodoxa emiliaria subleprosa subsp. nov. 



(J, 42-44 mm. ; $, 44-48 mm. Markings of name-typical emiliaria Gucn., 

 except that the antemedian line makes a rather stronger outward projection 

 in the cell ; coloration of upperside in both sexes closely hke that of leprosa 

 leprosa Warr., the distal area in the ? participating in some measure in the 

 heavy dark markings of fulgurea Prout (which I now regard as another sub- 

 species of emiliaria). 



Underside nearly as in e. emiliaria, the ? (but not the S) with a black 

 discal dot or small dot developed on the hindwing. 



Mount Rossel, Rossel .Island, November — December 1915 (VV. F. Eich- 

 hom), 2 (J (J, 4 $?, in coll. Tring Museum. 



3. Dysphania endoleuca spec. nov. 

 ?, 84-93 mm. Face cadmium yellow at sides, blackish down the middle. 

 Palpus blackish, first and second joints cadmium yellow beneath. Thorax in front
