 MONOCTENIAD^. 



MONOCTENIA NIPHOSEMA, n. Sp. 



9 , 50 mm. Head and palpi dull reddish-carmine, palpi 

 beneath fuscous tinged, antennaj ochreous, pectinations 1. 

 Thorax dull ochreous-carmine, becoming strongly suffused 

 with carmine on anterior half. Abdomen grey, mixed with 

 dull purple laterally and beneath. Legs ochreous, anterior 

 coxae dull carmine. Forewings elongate moderate, costa 

 slightly arched on basal third, slightly sinuate beyond middle, 

 termen rather strongly bowed, oblique, slightly sinuate 

 beneath apex, apex somewhat produced; dull ochreous-car- 

 mine, median third strongly suffused with carmine; costal 

 edge narrowly carmine throughout; a well-defined snow-white 

 spot in cell at J from base, faintly edged with fuscous; a 

 large dull fuscous spot in posterior extremity of cell; dusted 

 with whitish ochreous scales; a transverse fuscous line, 

 slightly curved outwards, from about | of costa to | of dor- 

 sum ; a row of fuscous dots, considerably beyond but parallel 

 to line; cilia carmine tinged with fuscous. Hindwings with 

 termen moderately rounded ; greyish-ochreous, broadly tinged 

 with fuscous-purple along termen; cilia dull purplish. 



Perth, Western Australia. One specimen; in November. 



DiCHEOMODES (?) TRIGLYPTA, U. Sp. 



( ? 9 ) 28 mm. Head, palpi, and thorax fuscous. ( An- 

 tennse broken.) Abdomen ochreous. Legs fuscous. Fore- 

 wings elongate, triangular, costa nearly straight, termen 

 oblique; brownish-ochreous ; a thick erect black line from 

 dorsum at J towards costa but hardly reaching it; an irregu- 

 larly waved moderately thick black line from costa at about 

 I to dorsum at about §, with a sinuation outwards in middle, 

 edged posteriorly by its own width of clear white and anter- 

 iorly by its own width of light ferruginous ; space between 

 this and erect line suffused with dull ferruginous; a well- 

 defined clear white line from costa at | to anal angle, with 

 a strong sinuation inwards just above middle, where it be- 

 comes thicker, strongly sinuate above and below this, edged 

 anteriorly by a thick dark fuscous shade throughout; a row 

 of fine white dots along termen; cilia ochreous-fuscous. 

 Hindwings with termen rounded ; pale ochreous-whitish ; faint 

 fuscous discal dot ; two parallel pale fuscous waved lines, from 

 costa at § and | respectively, reaching dorsum at § and | 

 respectively; cilia pale ochreous. 



Doubtfully referable to Dichromodes, the head being in 

 bad condition; it is a pretty and distinct insect. 



Dundas, Western Australia. One specimen; in Novem- 

 ber.
