NOTES ON ODOXATA OBSERVED IN GREAT BRITAIN. 283 



streaks, especially laterally ; anal tuft short, fuscous. Fore and mid 

 legs broken. Hind leg reddish brown ; tibia white on basal third, 

 slightly dilated at two-thirds and apex with scale-tufts, which each 

 emit a pair of moderate whitish black-tipped spurs, of which the 

 inner are the longer, tibia transversely banded wuth white at one-half 

 and three-fourths ; tarsi dark reddish-brown, joints banded basally 

 with white, bands broadest on first and fourth joints. Fore wing 

 cleft to a little beyond one-half, segments narrow ; first segment with 

 subfalcate apex and no posterior angle ; second segment very slightly 

 dilated posteriorly, tornus almost obsolete, termen oblique. Colour 

 light reddish-brown ; a longitudinal greyish discal shade from base of 

 wing to one-fourth, and prolonged less conspicuously into first seg- 

 ment, a minute black subbasal costal dot, a small black discal dot at 

 one-fourth, dorsal area suffused with blackish fuscous from base to 

 one-fourth ; first segment with indications (especially evident on 

 costa) of darker inwardly oblique transverse bars before and beyond 

 one-half, the ai'eas following these spaces lighter, and a few scattered 

 blackish scales ; second segment slightly suffused with blackish. 

 Cilia on costa dark fuscous mixed with whitish, before and beyond 

 three-fourths narrowly dark brown, followed by narrow patches of 

 ochreous- whitish, black at and before apex; on hinder margin of 

 first segment dark fuscous, blackish subterminally ; on fore margin of 

 second segment dark fuscous, with a few scattered black scales, 

 blackish preterminally ; on dorsum dark fuscous, cut with narrow 

 streaks of ochreous-fuscous ; on termen with a moderate black scale- 

 tooth beneath anterior angle. Hind wing cleft from about one-third 

 and from near base ; segments linear ; dark fuscous. Cilia dark 

 fuscous ; on dorsum with a large broad black scale-tooth at two- 

 thirds, a small black apical scale-tooth, remainder of dorsum thickly 

 strewn with scattered large black scales. 



One specimen labelled " Mashonaland : H. B. Debbie : 

 1903/174." The register gives these specimens as from Mashona- 

 land and Beira. 



The very narrow segments of the wings, combined with the 

 long palpi, seem to separate this from Oxyptilus. It may 

 possibly be a Tetraschalis, but wants the apical scale-teeth on 

 segments of hind wing usually characteristic of species of that 

 genus. As I am unable to examine the neuration, I will not 

 erect a new genus for this species, although such will probably 

 be required.
