deeply bilobed, the lobes triangular, with blackened edges 
and short pubescence. Highthsternitesimple. Ninth sternite 
divided apically into five parts—a pair of pubescent upper 
lobes, then a pair of bare intermediate lobes each ending in 
an upwardly pointing spine, finally a bare, internally grooved, 
bluntly pointed ventral lobe. Claspers hidden. 
Length of body about 13 mm.; wing 17 x 5°5 mm.

This very distinct species needs comparison with no othier. 
Pselliophora stigmosa, sp. n. 
Head orange. Palpi orange, the tip of the last joint 
darkened. Antenne with orange shaft and black pectinations. 
Thorax entirely orange. Abdomen orange, becoming more 
brownish posteriorly. Hypopygium with the ninth tergite 
deeply bilobed, the lobes clothed basally with long orange 
pubescence, and drawn out into two long black points. 
Kighth sternite with a narrow and rather deep emargination, 
clothed with rather long orange-brown pubescence. Ninth 
sternite with a pair of elongate, pointed, hairy upper lobes, 
blackened towards their tips; ventral lobe emarginate 
apically, with a double groove. Claspers black, square- 
ended. Legs orange, tibize, tarsi, and tips of femora black ; 
hind tibiz with a narrow but distinct yellow ring at the base ; 
traces of similar rings on the other tibie. Pubescenee of 
hind femora moderate, uniform. Wings orange; tip black 
from the cord outwards, including almost the whole of cell 
Cu,; a blackish blotch surrounding Rs except at base and 
tip; M broadly margined with black except towards base ; 
eells Cuz, An, and Ax mostly blackish except towards base. 
On the hind margin of the wing at the extreme base is a 
small patch of densely crowded short, stiff, black sete, facing 
a similar patch on the alula, and preceded on the wing-margin 
by a tuft of longish yellow hair. Rs gently curved ; cell dd, 
just sessile ; cell Cu, narrower at apex than cell Cu, Hal- 
teres orange. 
Length of body about 12 mm.; wing 12 x 3°38 mm.

This species has much resemblance to P. ardens, Wied., 
but differs in many details. ‘lhe peculiar patch of bristles at 
the base of the wing is no doubt a sexual character. Jt occurs 
also in the male of P. incunctans, Walk., but not in the 
female.
