termen, 8 and 9 stalked, 10 nearly approximated, 11 from middle. Hind- 

 wings 1, elongate-ovate, cilia 3 / 4 ; 2 — 7 nearly parallel, 7 to apex. 

 Perhaps near Toiana. 



Syncathartis argestis n. sp. 



9 16 mm. Head, thorax, and abdomen probably white (appearing pale 

 ochreous by discolouration). Palpi white. Forewings rather elongate-oblong,

 white : cilia white. Hindwings and cilia white. 



Java, Pekalongan (van Deventer); one specimen. 



Thyrsotarsa n. g. 



Head with appressed scales; ocelli posterior; tongue rudimentary. 

 Antennae ! / 2 , in çf fasciculate-ciliated, basal joint moderate, with pecten. 

 Labial palpi rather short, porrected, with appressed scales, terminal joint 

 shorter than second, pointed. Maxillary palpi obsolete. Post, tibiae above 

 with rough fine hairs becoming very long towards apex, tarsi above with 

 very long fine roughly projecting hairs. Forewings with lb furcate, 2 

 from towards angle, 3 and 5 approximated at base, 4 absent, 7 and 8 

 stalked, 7 to termen, 9 absent, 11 from beyond middle. Hindwings 3 / 4 , 

 narrowly elongate-ovate, cilia 1 '/ 3 ; 3 and 5 somewhat approximated 

 towards base, 4 absent, 6 and 7 closely approximated at base. 



Perhaps allied to Tarphyscelis and Podiasa. 



Thyrsotarsa platybyrsa n. sp. 



cf 11 mm. Head and thorax whitish. Palpi whitish, second joint 

 with apical half brownish. Abdomen whitish- ochreous, anal tuft white. 

 Forewings elongate, costa gently arched, apex obtuse, termen rounded,

 sum, where it extends from middle to beyond tornus, anteriorly irrorated 

 and posteriorly wholly suffused with ochreous-brown, towards dorsum 

 sprinkled with dark fuscous, with a spot of dark fuscous irroration in 

 disc towards tornus, and an irregular spot occupying tornus and lower 

 part of termen ; an apical spot of brownish and dark fuscous irroration : 

 cilia white, towards base and tips tinged with grey and somewhat sprink- 

 led with dark fuscous. Hindwings pale grey, anteriorly suffused with 

 whitish; cilia white.
