under this name to distinguish all species hitherto 

 referred to Azelina {Gonodontis, Hiibn.), in which the 

 antenna of the males are simple : M. Guenee gives as 

 his character, " Anteunes variables" ; they do not, how- 

 ever, vary in the same species, or in very closely allied 

 species. 



26. Dectochilus aittucaria. 



? Gonodontis antucaria, Felder and Eogenhofer, Eeise 

 der Fregatte Novara, v., pi. cxxiv, fig. 20 (1875). 



Both sexes vary considerably in the tint of the pri- 

 maries, which, in Mr. Edmonds' examples, is much 

 darker than in Felder's figure : the size of male examples 

 varies from 46 to 43 millimetres in expanse ; the smaller 

 specimens have also more strongly defined markings, 

 including a well-defined, minutely dentate- sinuate, sub- 

 marginal whitish line bounding a series of black or grey 

 spots ; the secondaries are also whiter than in the larger 

 variety. 



In my "Eevision of the Lepidopterous Genus Azelina" 

 (Ann. & Mag. Nat. Hist., Ser. v., vol. viii., pp. 29—46, 

 Jan., 1881) I have mentioned G. autitcaria, of Felder, as 

 " probably a species of Eurymene, but certainly not an 

 Azelina,'' and this is precisely the impression conveyed 

 by Felder's figure, which represents an insect not unlike 

 Eurymene alcoolaria ; but I expect that the figure is 

 either undercoloured or taken from an unusually pale 

 example ; it ought to have been regarded as an Azelina 

 in Guenee's sense, which admits the widest modifications 

 in the antennal structure. Apart from the non- 

 pectination of its antennae, D. antucaria is not unlike 

 the Crocallis tiisciaria of Europe. 



MoNOCTENiA ? Guenee. 



M. Guenee places this genus in a separate family, 

 which he calls CEnochromida, and, judging by the 

 Australian species alone, it seems very distinct ; but the 

 two following species, which, excepting that their an- 

 tennae are not quite so broadly pectinated (though quite 

 as much so as in (Enochromia), agree well with the 

 Australian types, are evidently not sufficiently unlike 

 Azelina to be referred to another family ; at any rate 

 that is my present opinion ; but, should breeding show 

 great larval differences necessitating such a disruption
