In the collection of the Paris Museum, a somewhat broken 
male specimen was found which is surely the male of this species. 
It is herewith described as allotypical. 
Male.—Similar to the female, differing as follows: Basal seg- 
ments of antennz yellow, passing into brown toward the tips; 
flabellations of antennze dark brown. Mesonotum entirely 
orange, including also the coxe and trochanters of all the legs; 
the forelegs are broken but the other legs are entirely as in 
the female. Abdomen black, the hypopygium conspicuously 
and abruptly reddish orange, only the caudal margin of the ninth 
tergite and the pleural appendages dark. 
LUZON, Manila, No. 246-1861. Allotype, male, in the collec- 
tion of the Paris Museum. 
Pselliophora tripudians is evidently allied to, but distinct 
from, P. incunctans (Walker) of Celebes. The thoracic pat- 
tern is paralleled in the two sexes of the two species. 
Pselliophora pumila sp. nov. 
General coloration black, the mesonotal prescutum yellow 
with three grayish brown stripes; all tibiz ringed basally with 
white; wings grayish brown; cells C and Se dark brown; a 
brown clouding along the cord; abdomen black, the caudal 
margin of tergites 2 to 4 narrowly yellow. 
- Male—tLength, 10 millimeters; wing, 11. 
Frontal prolongation of head dark brown; palpi concolorous. 
Antenne dark brown throughout; flabellations of antennz con- 
spicuously clothed with white hairs. Head dark brown. 
Pronotal scutum dark brown; scutellum dark brown me- 
dially, the lateral portions yellow. Mesonotal prescutum yellow 
with three conspicuous brown stripes that are dusted with gray; 
median stripe very broad; lateral stripes small, confluent with 
the median stripe near suture; pseudosutural fovese small, 
brown; scutum and postnotum black; scutellum black with con- 
spicuous, elongate, yellow bristles and delicate transverse rows 
of microscopic yellow hairs. Pleura dark brown, the extreme 
dorsopleural region faintly yellowish. Halteres dark brownish 
black, the base of the stem indistinctly yellow. Legs with the 
coxe and trochanters black, femora black, about the basal half 
of the posterior femora more testaceous; tibie black with a 
conspicuous white ring just beyond the base, this broadest and 
most distinct on the posterior tibie; tarsi black. Wings clouded 
with grayish brown; costal region dark brown, including cells 
C and Sc; paler brown clouds along the cord and along vein Cu; 
veins dark brown. Venation: Sc, ending about opposite two-
