NEW GENEEA AND SPECIES OF GEOMETRIDAE. 



By \V. warren, M.A., F.E.S. 



THE types of the species here recorded as new are all contained in the Rothschild 

 Museum at Tring. To these descriptions arc added diagnoses of new genera, 

 and a few rectifications of generic and specific names, witii critical notes where 

 necessary.

Oenochromidae Meyr. 

 Nearcha iirsaria Ouen. 



Guende's descri])tion of unnrin is taken from a J ; the examples in the British 

 Museum, four in number, are all <?(?, agreeing exactly with his description of the ? . 

 In these, however, all the nervures of the forewings are thickly traced with hair-like 

 scales, and the neuration itself of the lower nerves is subject to an anomalous distor- 

 tion, so striking that, did it obtain in the j , I think Uuenee would hardly have failed 

 to observe it. The submedian nerve, the submedian fold, and the fir.st median ner\ule 

 are all three abruptly bent downwards beyond the middle of tlie wing towards the 

 anal angle. This distortion is more especially noticeable in the case of the first 

 median ner\-ule, which runs at a strong angle so as almost to join the fold. The fore- 

 wings are, as Guen6e states, much more strongly falcate than in huffalarin. 



I imagine, as Mr. I\Ieyrick makes no mention of these anomalies in his descrii)- 

 tion of bujfalitriii, which he makes identical with ursaria, that he has never seen the 

 underside of Walker's four S S  Three of these Walker himself referred to bi(ffal(triii 

 and one to iwsdvia, and then added, " These species seem to be identical." 



Antasia nom. nov. 

 Darantasia (Wlk,, x.wi., p. ITili, nom. praeoc). 

 Tliis name of Walker's cannot stand, as he had already used it {.foiirn. Linn. Soc, 

 iii., p. ISO) for a totally different in.sect. 



Lyrcea (Wlk., xx., \>. 259, 1860). 



Meyrick erects a ianiily for the insects of this genus, Lyrceidae ; but, as the 

 Oenochromidae, the majority of which are endemic to Australia, Tasmania, and New 

 Zealand are, as far as neuration goes, a somewliat loosely defined family, it seems to 

 me preferable, at all events at present, to include the present genus /y^rcea in it. 

 The species inter se are very variable. Jleyrick refers both cwhroiaria Feld., varians 

 Butler, and iistaria Wlk. to alectoraria Wlk. as one species, to which he adds as a 

 second Jlemerojthila hemiptcrtiria Gueii. (which I have not seen), which he had ])re- 

 viously separated under a new generic name Xyridacma. I consider achraiuriii 

 Feld. decidedly distinct from the ^^'alkerian species. It is very variable, hut nchroinria 

 has a distinct angulation in the outer margin of the forewing, while alecloriirin Wlk. 

 is always larger, invariable, with scarcely any markings, and the costal edge red, 

 esix-'cially at the base. Usturia Wlk., the type of which isiu the British Museum, and
