144. Locastra elegans, n. 8. 
Fuliginous-brown ; wings with bronzy reflections ; 
primaries with a broad central area slightly tinted with 
greenish in certain lights, bounded at basal fourth by a 
slightly oblique black line, enclosing two black discoidal 
spots, and bounded outwardly by an arched and elbowed 
black discal line at external third; a marginal series 
of black spots ; fringe pale, with whitish basal line and 
dusky spots ; secondaries pale, excepting along the apical 
border, the discoidal area opaline white ; fringe whitish, 
traversed by a dusky stripe; anal tuft whity brown ; 
under surface almost exactly as in L. amica ; expanse of 
wings, 1 inch 4 lines. 
Yokohama (Jonas).

145. Saraca costinotata, n. s. 
Pale olivaceous-brown; basal area of primaries, a 
broad band just beyond the middle, and an external 
border with undulated inner edge, slaty grey; a tri- © 
angular snow-white costal spot at apical third followed 
by a minute white dot ; fringe short, grey, with a whitish 
basal line; secondaries with the basal three-fifths and 
the external border slaty grey ; under surface pale bronzy 
brown, with greyish opaline tints in certain lights ; pri- 
maries with two white costal dots towards apex ; expanse 
of wings, 1 inch 1 line. 
Yokohama (fH. Pryer). 
Allied to S. trimantesalis (Hgnasia trimantesalis, W1k., 
which sbould be placed in Saraca). 
146. Saraca subviolacea, n. s. 
Greyish brown, with a faint violet gloss; wings with a 
slender pale-edged marginal black line; primaries with a 
slender abbreviated black line across the base of the 
costal border, a sinuous black stripe across the basal 
third, a rather broad elbowed black band, with sinuated
