118. Hydrelia papuensis spec. nov. and ab. dorsinotata nov. 



Forewing : pale greyish ochreons, tinged with darker, and crossed by a 

 succession of slightl}- darker luiuilate-dentate lines, the teeth all pointing inwards 

 and forming slight brown points on veins, tlie liiniiles of the outermost series also 

 marked at their aiiices with a brown jmiat between the veins; a row of large brown 

 marginal spots ; the line marking the outer edge of central fascia is more strongly 

 exjiressed and followed closely by two grey lines, forming together a narrow band ; 

 between veins 3 and 4 the outer of ithese three lines and the two praesnbmarginal 

 lines are marked, sometimes strongly, with Ijrown-black sealing ; cell-spot small, 

 black ; fringe pale oclireons. 



Hindwing: similar, without the basal lines, and with no dark scaling between 

 3 and 4. 



Underside paler, tlie lines much fewer, but darker, and only the outer ones 

 distinct ; cell-spots black, also the marginal spots, those of forewing being much 

 swollen. 



Head, thorax, and abdomen dusky grey ; dorsal segments with dark middle 

 spots, second segment with a pair, one on each side. 



Expanse of wings : 26 mm.

The species is nearest to // atrostrignta Warr. from Qneensland. 



It shonld be noted that though 1 have jilaced this sjiecies in ]li/<hrU(t, as 

 having apparently a single areole, the areole is actually double, vein id running 

 into 11 close to its origin, so forming one very small triangular inner and a large 

 outer areole. I am inclined to think that this small inner areole, situated as it is 

 far bascwards, is often overlooked. 



In the aberration a large lilack-brown sinuous lilotch rises from middle nf inner 

 margin of forewing, where it is liroad, and is bent (lutw^ards at lower end of cell 

 between veins 2 and 4. 



no. Poecilasthena paucilinea spec. nov. 



Dill'ers from /'. thalassias Meyr. in two respects ; tlie hindwings ot //i<i/(issias 

 arc at most bluntly elbowed at vein 4 ; in paucilinea the hindmargin is distinctly 

 angled, vein 4 forming a sliort tooth ; secondlv, in thahiKsius the lines forming the 

 central fascia are four in number ; in the present species they are but three ; the 

 pale band on each side of the central fascia is traversed along its centre by a green 

 waved line in thalassias ; in paucilinea the bands themselves are broader, the 

 traversing line keeps close to the edge farthest from the fascia, which is therefore 

 limited by a broader space of pale ground-colour. In all otlicr jioints the species 

 appear to agree.
