Odites notosticta, n. sp. 
$ . 19 mm. Head, thorax yellow-whitish. Antennal ciliations 
fasciculated (4). Forewings suboblong, costa anteriorly moderately 
arched, apex rounded, termen rounded, vertical; 2-4 nearly approxi¬ 
mated at base ; yellow-wbitish ; a cloudy grey spot on dorsum at ^ ; 
discal stigmata small, suffused, light yellowish-grey : cilia ochreous- 
whitish. Hindwings and cilia whitish.

Odites holotorna, n. sp. 
9 . 26 mm. Head, thorax white. Palpi white, second joint 
externally grey except towards apex. Forewings rather broad, 
costa strongly arched, apex wholly rounded off, wing longest on 
vein 4, rounded beneath ; 3-5 nearly approximated at base ; white, 
in certain lights with faint grey tinge ; first discal stigma minute, 
dark grey, second obsolete: cilia white, towards base faintly 
ochreous-tinged. Hindwings and cilia ochreous-wbitish. 
Camurooxs, Bitje, Ja B., 2000 feet ( Bates ); 1 ex. This very 
interesting insect, whilst techically a true Odites , and certainly 
allied to the preceding species, is, in the curious and highly 
characterised shape of wing, and the exact disposition of veins, as 
well as other structural and superficial characters, a typical Stenonia 
such as c/rcivdis , except only that veins 7 and 8 of forewings are 
stalked, a character found in some undoubted members of the 
Stenomid subfamily, such as Energia ( Aplianoxena ) and Falculina. 
It appears to me that this is not fortuitous, and that it really docs 
mark the true point at which Odites, representing the original form 
of the Xyloryctid subfamily, branched off from the Stenomid. Its 
African origin is therefore appropriate, and dates back to the 
period (remote in the history of the Tineinct) when that continent 
was united with South America. 
HYALOPSEUSTIS, n. g. 
Head smooth; ocelli small, inferior; tongue developed. An¬ 
tennae 4, in 6 moderately and evenly ciliated, basal joint moderate, 
stout, without pecten. Labial palpi moderate, straight, sub¬ 
ascending, second joint rather thickened with smooth appressed 
scales, cylindrical, terminal joint very short, rather thick, obtuse. 
Maxillary palpi rudimentary. Anterior tibiae and tarsi short, 
stout; posterior tibiae with appressed scales. Forewings 15 fur¬ 
cate, 2-5 nearly approximated from angle, 6-9 rather approxi¬ 
mated at base, 7 to apex (indefinite), 11 from middle. Hindwings 
over 1, subovate, cilia ^; cell and dorsal area without hairs; 
3 and 4 connate, 5 much nearer 4 than 6, rather approximated 
at base, 6 and 7 stalked. 
A development of Stenoma , entirely normal in neuration, but 
remarkable for the quite peculiar palpi, and the absence of discal 
and subdorsal hairs, and for the abnormal presumably mimetic 
superficial appearance.
