^ings moderate, costa rather strongly arched, a,p€x rounded, 

 termen hardly oblique, rounded beneath ; pale grey, some- 

 times suffused with pale pinkish ; costal edge light rosy ; nume- 

 rous dark grey dots, sometimes mostly obsolete, arranged in 

 irregular transverse series; a larger transverse dark fuscous 

 dot in disc beyond middle; cilia grey-whitish, more or less 

 pinkish-tinged. Hindwings light grey or whitish-gi'ey ; cilia 

 grey-whitish. 



Geraldton, York, and Perth, West Australa, in November ; 

 eleven specimens. 



Allied to the preceding, but distinguished by the hindwings 

 not being yellowish, and the absence of the darker prsetornal 

 cloud. 



CERYCOSTOLA, n. g. 



Head with loosely appressed scales; tongue developed. An- 

 tennas (1), basal joint moderate, without pecten. Labial palpi 

 very long, recurved, second joint with appressed scales, much 

 exceeding base of antennae, terminal joint considerably shorter 

 than second, acute, rather thickened with scales, with a median 

 tooth of projecting scales posteriorly. Posterior tibiae loosely 

 haired. Forewings : 2 from near angle, 7 and 8 stalked, 7 to 

 apex, 11 from before middle of cell. Hindwings (1), ovate, 

 cilia one-sixth ; 3 and 4 connate, 7 bent downwards in middle. 



I am now of opinion that my reference of the following 

 species to Gonionota, Zell., was not justified; Zeller's definition 

 of his genus is extremely imperfect (the neuration not being 

 described at all) ; the only tangible distinctive character given, 

 the median posterior scale-tuft on terminal joint of labial palpi, 

 since it occurs also in the allied Binsitta and Semiocosma, may 

 belong to more than one other genus. Hence I give it a new 

 generic name ; the structural characters as above were not 

 published with the species, but I described them at the time 

 from the original types. 



The genus is clearly allied to Peritorneuta. 



Cerycostola pyrobola, Meyr. 

 {Gonionota pyrohola, Meyr.. Proc. Linn. Soc, New South 

 Wales, 1886, 1041.) 



I have seen no specimens excejpt the original types. 



BINSITTA, Walk. 



Head with appressed hairs; tongue short. Antennae (J), 

 in male simple, basal joint elongate, without pecten. Labial 

 palpi very long, recurved, second joint much thickened beneath
