of Heterocera from Japan. 169 
much paler, the primaries showing the spots of the upper 
surface, the transverse lines indistinct, secondaries without 
markings. Expanse 1 inch 7 lines. 
Yokohama (Jonas). 
A well-marked species, far more pleasing than the European 
one. 
BRACHYXANTHIA, n. gen. 
Allied to Xanthia and Xestia, but differing in the short 
costal margin of the primaries, the consequently much more 
convex outer margin of the same wings, the shorter and 
rounder secondaries, and the longer and more porrect palpi. 
Type B. peculiaris. 
103. Brachyxanthia peculiaris, n. sp. 
Primaries bright stramineous, crossed by brown lines as in 
XAestia ochreago; an additional dark brown oblique line from 
apex to inner margin, from which a second line is given 
off from below the reniform spot and runs to the basal 
third of the costal margin (the two lines together forming a 
large Y on the right-hand wing); the disk immediately be- 
yond the oblique line purplish brown in the male ; secondaries 
sericeous brown, the costal area, fringe, and outer margin in 
the female creamy whitish; body coloured like the wings: 
wings below pale creamy yellow, with a brown discal line 
which in the male primaries is expanded into a broad band or 
patch; veins of outer margin, marginal lunules, and a costal 
dash in primaries brown. Expanse 1 inch 2-3 lines. 
Hakodaté (Whitely), Yokohama (Jonas). 
104. Mesogona contracta, n. sp. 
Allied to M. acetoselle, but with narrower wings ; primaries 
darker, the outer stripe angulated towards the costa; no black 
discal dots, but a third pale irregular line limiting the greyish 
external border ; secondaries greyer than in MV. acetoselle, with 
black marginal spots; body altogether greyer, the abdomen 
grey, bordered and tufted with reddish: wings below sordid 
whitish, tinted with pink ; a black discocellular lunate spot, a 
blackish discal stripe, and marginal black dots on each wing ; 
primaries with the medio-discoidal area greyish; body greyish 
brown. Expanse 1 inch 11 lines to 2 inches. 
Yokohama (Jonas). 
It is just possible that this may be Motschulsky’s “Agrotis 
cinnamomea ;” but the description is not good enough for 
identification.
