mediaii band transverse, biconcave ; cilia fuscous. Hindwings 

 scai'cely broader than forewings ; hindmargin sinuous ; grey, 

 towards base ochreous-tinged ; cilia pale ochreous, with a suf- 

 fused greyish median line. 



Allied to X. Icttiorella, Wlk., but readily distinguished by 

 the wholly dark cilia of forewings. 



Townsville, Queensland, in October; a series bred by Mr. 

 F. P. Dodd. 



Tyipe in Coll. Walsingham. 



Brachybelistis, n. g. 



Head with appressed scales. Palpi slender, recurved, short, 

 jiot reaching base of antennae; terminal joint minute, pointed. 

 Maxillary palpi minute. Tongue obsolete. Antennae in male 

 simple, moderately ciliated. Thorax not crested. Forewings 

 with vein 2 from three-fourths to five-sixths, 7 and 8 stalked, 7 

 -to termen. Hindwings with 3 and 4 stalked, 6 and 7 connate 

 •or stalked. 



Differs from Xylorycta, Meyr., in the very short palpi, 

 with minute terminal joint. It is certainly a good 

 genus, the known species being closely related and having a 

 peculiar facies. 



Brachybelistis neomorpha, Turn. 



{Xylorycta neomorpha, Turn., Annals Queensland Mus., iv.. 

 13, 1897.) 



The hindwings differ in the two sexes. In the male they 

 are dark fuscous, with ochreous-whitish cilia, in the female both 

 hindwings and cilia are grey. The anterior and middle tibiae 

 and tarsi and posterior tarsi are crimson in the male, pale 

 ■orimson in the female. 



Gryptophaga hlachhurnii, Low. Tr. Roy. Soc., S.A., 1892, p. 

 15, appears to be a closely allied species. 



Brachybelistis pentachroa. Low. 



{Xylorycta pentachroa. Low. Trans. Rov. Soc, S.A., 1901, 

 p. 83.) 



Male, 21 mm. Head and antennae blackish; antenna! cilia- 

 tions moderate (IJ). Pal,pi ochreous. Thorax blackish, 

 patagia ochreous. Abdomen blackish, dorsum of third seg- 

 ment ochreous. Legs ochreous, femcea dark fuscous. Fore- 

 wings elongate, costa very slightly arched, apex round-pointed, 

 termen nearly straight, oblique ; ochreous-yellow ; a blackish 

 discal dot before middle, confluent with a large blackish blotch, 

 which occupies whole posterior half of wing except costal and
