darker in some examples than in others, and occasionally 
crossed by a discal series of dusky spots ; fringe broader than 
in O. levis, whitish: under surtace paler than in O. levis, 
with well-marked discocellular spots and discal series blackish. 
Expanse 1 inch 6 lines. 
Yokohama (Jonas). 
In some respects this species resembles Tventocampa gracilis. 
100. Dasycampa fornax, n. sp. 
Nearly allied to D. rudbiginea, but slightly larger, altogether 
redder ; the lines and dots on primaries less sharply defined, 
egreyer; the secondaries paler greyish, with distinctly rosy 
borders ; abdomen whitish at base, otherwise rosy ; primaries 
below redder, without the black discocellular spots or greyish 
nebula in primaries, the other markings ill-defined ; secondaries 
redder, the discal line more irregular and less defined: body 
below altogether redder, especially in front. Expanse 1 inch 
6 lines. 
Yokohama (Jonas). 
D. fornax may possibly be the insect intended in Mot- 
schulsky’s vague description of ‘‘ Oporina ? castaneo-fasciata ;” 
but it is extremely doubtful. 
101. Hoporina sericea, n. sp. 
Coloration of /7. croceago, but the primaries more elongated 
(the form of Xanthia gilvago); the grey markings on the 
primaries less distinct than in H. croceago, excepting the three 
angulated transverse lines ; primaries below rather redder, the 
markings better-defined, secondaries with the markings less 
defined. Expanse 1 inch 8 lines. 
Yokohama (Jonas). 
But for the entirely different form of the primaries, this 
might have been considered a variety of 4. croceago ; it, how- 
ever, differs in its more sericeous wings, the secondaries having 
quite a pearly appearance by the side of the typical species. 
102. Eupsilia tripunctata, n. sp. 
Allied to 2. satellitia, but the primaries silvery grey, with 
slightly dusky central area and outer border; the transverse 
lines wider apart, the outer one less irregular; the limit of the 
external border indicated by a brown instead of a pale lunu- 
lated line; the three white spots considerably larger, and 
arranged in a triangular figure, the largest one D-shaped 
rather than lunate, the lower of the two others much larger 
than the upper one, and about one fourth the size of the D- 
shaped spot; secondaries and body also greyer: wings below
