Xanthorhoe lucidata Walk. 



The insect identified by Hudson as A", lucidata is not the typical 

 lucidata of Walker. The true lucidata is smaller in size, lines less 

 straight, colours more varied, &c. Hudson's species agrees exactly with 

 veinapuncta Walk. The whitish dots on the veins are quite characteristic 

 of the species. 



Lythria euclidiata Guen. 



The large form without any red on the underside is L. euclidiata Gn. ; 

 the smaller, which answers to Hudson's description and figure, is 

 aatapurrha Butl. This latter should be known as Arcteothes catapyrrha 

 until it can be proved that the two strikingly different forms are con- 

 specific. 



Dichromodes petrina Meyr. 



Petrina sinks to an older name — sphaeriata Feld. — which was un- 

 known to (or unidentified by) Meyrick, through Felder having assigned 

 it not only to the wrong genus, but to the wrong subfamily, and given 

 rather a poor figure of it. 



E pirranthis alectoraria Walk. 



Sufficiently distinct from the true Epirranthis to form a new genus 

 under the name Xynonia (Prout) ; and included in alectoraria are 

 apparently two species — Xynonia alectoraria, the long-winged species 

 with the margins irregular; Xynonia ustaria (Prout), the stumpier- 

 winged with strong angle (almost a tooth) in middle of outer margin of 

 forewing and with strong dentate margin of hindwing. 



E pirranthis hemipteraria Gn. 



This should be Xyridacma hemipteraria : the singular form of the 

 hindwing renders it convenient to keep it separate from Xynonia. 



Drepanodes muriferata Walk. 



Drepanodes is a South American genus, and, as your New Zealand 

 muriferata is probably structurally distinct therefrom, it seems prema- 

 ture to merge them, so advise keeping to the generic name Gargaphania 

 Walk, expressly founded for muriferata. 



Leptorneris rubraria Dbld. 



This should be Acidalia rubraria. The genus has been known by 

 quite a number of synonyms (Leptorneris, Craspedia, Emmitis, &c), but 

 Acidalia is the oldest name for it. 



Selidosema . 



Selidosema Hubner is a European genus, and probably does not 

 occur in New Zealand. Meyrick (Trans. N.Z. Inst., vol. 17, p. 65) made 

 a genus Gelonia for S. panagrata and S. dejectaria. This had better 

 stand provisionally. 



It would be well to use Pseudocoremia Butl. for sua vis, lupinata, 

 rudisata (" rudiata " is an orthographical alteration of Hudson's), 

 melinata, ochrea, and allies — apparently a quite compact group. 



Sestra humeraria and Sestra flexata Walk. 



Hudson has unfortunately transposed these two. It is really Butler's 

 fault, at least in part, and shows the mischief of premature lumping.
