mens, and Mr. Koebele having reared it from larva? feeding between the 
leaves of ^hiercus agrifolia. 
This genus was described bj Zeller in 1875 (Verh. z. b. Ges., Wien., vol. 
xxv, p. 324), and referred to the Choreutince as a close ally of Simcethis, but 
only two species were described, those with which I have compared it. 
His generic characterization is imperfect from lack of material, but I will 
give a more full characterization at some future time. 
Named after our well-knoAvn micro-lepidopterist, Prof. C. H. Fernald. 
WALSINGHAMIA, Gen. nov.Head distinct, somewhat protuberant be- 
tween the eyes, but not tuberculate or mucronate ; ocelli distinct, large; 
palpi slender, reaching to about the middle of front; terminal joint scarcely 
more than half as long as second, slender, with a pointed tip; no maxil- 
lary palpi ; tongue moderate ; antennae for about half their length thickly 
clothed with scales above; beyond this the joints are well marked, and 
mobility seems practically confined to this part of the antenna; a broad 
white ring just above the thickened part, otherwise black, basally marked 
with ferruginous scales above. Thorax smooth and well rounded at shoul- 
ders ; legs stout, rather short, densely clothed with scales, the tarsi most 
distinctly so, the segmentation so obscured that they seem four-jointed ; 
tarsal claws very minute and simple; median tibia two-spurred, posterior 
with both median and terminal spurs of good length, the former rather 
more, the latter less, than one-third the length of the tibia. Wings rather 
large ; primaries with costa distinctly arched toward apex, which is some- 
what acute; posterior border oblique to the obtusely rounded anal angle; 
i2-veined; dorsal vein furcate basally; costal vein (12) strong, from base 
to costa beyond the middle; n from subcostal about one-third from base 
to costa ; subcostal from base to end of cell, and continued thence unbroken 
to costa rather within half its entire length it forms a slight angle, giving 
rise to a faint vein running to the cross-vein and forming a large accessory 
cell; cross-vein distinct between veins 9 and 10 (which are widely sepa- 
rated); 9 to costa near apex, forming a series of faint curves between 
veins 4 and 9; 5 to 8, inclusive, decidedly weaker than the other veins; 8 
from cross-vein to apex, equidistant between 7 and 9, which are not farther 
apart at base than 5 and 6: 7 continuing from the faint vein closing the 
accessory cell to the hind margin below apex ; 5 from cross-vein, nearly 
midway between 4 and 6 nearer the former to the hind margin ; 3 and 
4 from the end of the median, and rather close together ; 2 from the median, 
about f from base, to outer margin ; i (dorsal vein) from base to anal 
angle. Secondaries with veins 5 to 7, as well as the subcostal, much 
weaker than the others ; costal vein free from base to costa near apex ; 
three dorsal veins, the intermediate (i b] distinctly furcate basally ; median 
giving off 2 close to the end of the cell and continuing beyond, giving off 
3 and 4 on a stalk, half way to the hind margin ; 5 from the cross-vein 
about midway between 4 and 6; 6 from the cross-vein nearer to 7 than 5; 
7 continuing the subcostal from the end of cell to the apex; a faint longi- 
tudinal vein divides the cell and terminates on the cross-vein between 5
