THYEGORINA.— LACHANA, 29 



under surface the primaries are wliite, the costa aud discoidal cell sliglitly tinted with roso- 

 red; the spots of the postmedian series arc distinct, aud those nearest the costa much 

 enlarged: the secondaries are whiter than above, with similar markiugs : body below white; 

 a tuft at the base of the primaries; the autcrioi- cox;c and ii[)pcr surface of femora rose-red ; 

 tibiie and tarsi greyish brown, but the posterior tibiie varied with white; venter with two 

 lateral series of black spots. Expanse of wings 39 millim. 

 Kaugra valley. 



/S. sagittifera of Moore does not appear to be distinct from ii. caslynctu, Kollar, aud 

 therefore is not described here.

Allied to T. rhodophila ; the wings more elongated ; the secondaries of the male with a 

 grey spot at the end of the cell, those of the female sometimes with three widely separated 

 submai'ginal spots, the first indistinct, subcostal, the second subajjical, the tliird close to the 

 outer third of the first median branch ; thorax of male above ochreous, of female white ; 

 abdomen of the female with a broad central carmine belt, with dorsal and lateral black spots ; 

 the basal and anal segments snow-white ; abdomen of male wholly carmine : wings and body 

 below white ; costa of primaries cream-coloured, not orange as in T. rhodophila. Expanse of 

 wings, ^ 36 millim., ? 43-50 millim.

The Eujjrepia imperialls of Kollar (collected by Mr. Hocking) has hitherto been placed 

 in the genus Areas : in neuration it is very similar, excepting that the lower half of the disco- 

 cellular veinlet is comparatively slightly longer, and the lower radial of primaries and radial 

 of secondaries ai'c emitted from the same point with, instead of close to, the third median 

 branches ; the antennse, however, are decidedly longer and more closely pectinated, and the 

 palpi much longer and coarser in KoUar's species, which may be separated under the name of 

 Melaiiareas. 



LACHANA, Moore. 



Form and neuration of Phaos; pattern very similar liut obscure; body similar to that or 

 P. hnttonii, with a number of long and rather straight pale hairs from the tegulrc and abdomen ; 

 antennse much more broadly pectinated. Type L. htdalwnsis. 



In his ' Revision of A^istralian Lepidoptera,' part 1, Mr. Meyriek has separated two species, 

 one of which is P. huttonii, under the generic name of Metacrias ; an examination of the
