186 Mr. R. M‘Lachlan on the 
tarsi somewhat fuscescent. Wings more elongate, and 
the apex more elliptical than in the preceding species; 
the posterior pair more dilated in the middle; whitish, 
with deep black markings as follows :—in the basal por- 
tion are three narrow longitudinal lines, viz., one on the 
costa ( broader than the others), and ending in a connected 
(or isolated) spot; one in the middle, oblique, and extend- 
ing to the inner margin at the base of the fascia; one on 
the inner margin (absent in the posterior wings, but there 
is a spot in its place); a narrow, oblique fascia beyond 
the middle, and a small apical space (enclosing a pale 
spot), also two small curved lines on the inner margin, 
between the fascia and the apex; veins black. In the ¢ 
there is the usual broad median production of the posterior 
margin of the 3rd segment; 7th and 8th segments very 
short, the 7th deeply excised on its apical margin above, 
the 8th broadly conical; cheliferous segment large, as long 
as the 7th and 8th united; claws short; appendages 
apparently very broad and nearly truncate. 
Eixpanse 35—36 mm. 
One pair ($%, which do not vary) from Yokohama 
(Pryer), in Wormald’s collection, and a ? from Hakodaté, 
in the British Museum. ‘This latter has the markings of 
the wings rather less emphasized. 
P. Wormald?, sp. nov. 
Black; the sides of the rostrum pale. Legs yellowish. 
Wings narrow and elongate, with elliptical apex, whitish, 
with blackish (not deep black) markings as follows :—the 
costal margin with a streak from base to apex, and a small 
connected spot before the first fascia; the inner margin 
also with a streak in which are three pale spots; beyond 
the middle of the wing are two very narrow fasciz, each 
starting from the costal streak, and each broadly furcate 
in its lower half; beyond the second fascia is a simple 
linear fascia, and the apical dark portion is also very 
narrow. 
Eixpanse 29 mm. 
One ¢ from Yokohama (Pryer), in Wormald’s collection.
