HADENELLA Grote (1888). 
This genus is based on a Hadenoid of slight build, having triangulate, 
broad wings, the infra-clypeal plate prominent, a curious projecting 
frontal horn terminating in a navel-shaped expansion. The thorax is 
tufted behind, the antenne simple, the eyes naked ; a small basal tuft on 
the abdomen. The little moth is gray, shaded over apices and the middle 
of the wing with ochreous, thus resembling in miniature Agrotis Pluralis. 
It is of the same slight form, but brighter colored than the dusty gray Ha- 
dena cylindrica.

This genus is composed of small Hadenoid forms which have clear yel- 
low secondaries with black borders, and resemble Anarta myrtilld in ap- 
pearance. The eyes are naked, the head not as prominent as in typical 
Hadenoid species. The antenne are simple, the vestiture hairy, the 
thorax tufted. It is a color genus apparently as the tibise are unarmed, 
and beyond the peculiar color, and somewhat compressed form I do not 
find distinctional characters, although I cannot help believing that such ex- 
ist. The species are near, but I now believe are all distinct. All but 
Aurea have yellow, this has orange secondaries. The fore wings of 
Crocea are shaded with ochrey and paler than the others. It is probable 
that the Q oviduct is exserted, which would give a slight character,

TOTA Grote (1882). 
Type: T. Armata Grote. 
Size small, form compact, fore wings somewhat tortriciform, shaped 
like the Furopean Senta, with hadeniform ornamentation, gray, with faint 
markings finely outlined. Tibise slender, unarmed, fore tibise with a short 
claw. Olypeus with an exceedingly. prominent wedge-shaped protuber- 
ance, surmounting the greatly exserted infra-clypeal plate. Hind wings 
rather full, rounded, the fringe prominent. 'Two species, one larger with 
pale fuscous or smoky secondaries, the second smaller with glistening 
white hind wings, resemble each other closely in appearance. On exami- 
nation, the central point of the clypeal wedge has a shallow depression on 
top in the second smaller form (minorata), in which the head and collar 
are distinctly ochrey. The larger form (armata) has a variety having a 
submedian and discal black streak; this recalls the var, Bipuncta of the 
European species of Senta, although it is the stigmata which are filled 
with black. The untufted body, the clypeal armature resemble Nonagria; 
the small species have the look of internal feeders.
