longitudinal median streak, from neao: base to apex, attenuated 

 posteriorly and nearly connected with cosita at base by a 

 naiTow fuscous shadei; streak edged below in middle by a 

 fine white line, which becomes dot^like at posterior extremity ; 

 a fine short black line along fold towards base ; a 

 small black spot below co'mmencement of white streak ; 

 a row of black elongate spots along termen ; cilia cinereousr- 

 grey, becoming blackish at base and on streak. Hindwinga 

 elongate-ovate ; termen rounded : light fuscous ; cilia greyish 

 fuscous, becoming greyish-ochreous at base. 



This species, which resembles xipliostma very closely, is 

 doubtfully referable to this genus. The palpi are unfortu- 

 nately broken, with the exception of the second joint, which 

 agrees in structure with the genus, but the well-developed 

 pecten of the antenuce is discordant, as in both the previous 

 species examined it is absent, although the material at my 

 command is scanty, so thati I caiinOit insist on the point. 

 Should it ultimately prove to be correctly located, then the 

 characters of the genus will have to be altered so as to 

 read : Antenn?e with moderate pecten, basal joint moderate, 

 ciliations (1). The present species differs chiefly from 

 xiplioiiema by the narrower forewings, elongate dots along 

 termen and fuscous hindwings. 



Broken Hill, New South Wales; one specimen in August. 



PSOROSTICHA, n. g. 



Head with appressed scales. Thorax strongly crested 

 posteriorly. Antennje dentate, shortly ciliated, with pecten. 

 Palpi moderate, recurved, second joint hardly exceeding base 

 of antennae, densely and roughly clothed with appressed scales, 

 terminal joint shorter than second, thickened with rough scales 

 at two-thirds, apex acute. Abdomen rather broad. Pos- 

 terior tibiifi clothed with long hairs. Forewings elongate, 

 moderate, termen obliquely bowed, s|urfaco with tufts of 

 scales ; 2 and 3 stalked, 7 and 8 stalked, 7 to just above apex. 

 Hindwings elongate-ovate. 3 and 4 from a point, 5 approxi- 

 mated to 4 at base, 6 and 7 parallel, cilia over one-third. 



Not very near any other Australian genus known to me. 

 Its nearest ally appears to be Trachype'pla, Meyr., but the gap 

 is rather considerable on account of the stalking of veins 2 

 and 3 of forewings and shoit antennal ciliations. In structure 

 it more nearly approaches the European genus Exaeretia, Stt., 

 differing principally by the termination of vein 7 on costa, and 

 raised scales on forewings. The species here described has the 

 facies of a Gelechia.
