21,4 Alexander: Little-known Tipulide (Diptera) 381 
than the ultimate section of R,; cell M, rather broadly sessile; 
m-—cu distinct. 
Abdomen with segments 1 and 2 orange, the extreme lateral 
apical angle of tergite 2 darkened; remainder of abdomen shiny 
black, only the tips of the ovipositor deep reddish. Valves of 
ovipositor comparatively long and slender. 
MINDANAO, Bukidnon Subprovince, Tangcolan (Baker). 
Pselliophora perdecora belongs to the incunctans group of the 
genus, an aggregation of large, showy species that contains 
some of the most beautiful crane flies known. Pselliophora 
incunctans (Walker) and P. ineunctans ochrifemur Enderlein of 
Celebes, P. praefica Bezzi and P. tripudians Bezzi of the Philip- 
pines, and possibly other species belong to this group. 
Pselliophora praefica Bezzi. 
Pselliophora praefica Brzzi, Philip. Journ. Sci. § D 12 (1917) 110. 
The undescribed female of this species may be described as 
follows: 
Length, 21 millimeters; wing, 19. 
Head black, the gene and occiput deep reddish brown. Other 
characters entirely as in male. Ovipositor with the valves 
black, only the extreme tips reddish. 
MINDANAO, Kolambugan (Baker). Allotype. Female. The 
allotype has been returned to Professor Baker. 
Bezzi’s type male was likewise from Mindanao. In the collec- 
tion of the State Natural History Museum in Vienna, Brunetti ' 
found a male and a female of this species from Palawan. These 
he considered to represent a variety of P. incunctans (Walker), 
but in my opinion there can be no doubt but that P. praefica 
is a distinct species. 
Pselliophora tripudians Bezzi. 
Pselliophora tripudians Bezzi, Philip. Journ. Sci. § D 12 (1917) 111. 
A female agrees very closely with Bezzi’s description except 
that the specimen is smaller (length, 17 millimeters; wing, 16). 
The foreleg, lacking in Bezzi’s type, is very different from the 
other legs and may be described as follows: Femora entirely 
light yellow, the tip not darkened; tibize yellow, the tip a little 
infuscated; tarsi entirely brownish black. 
LUZON, Laguna Province, Los Bafios (Baker). This specimen 
has been returned to Professor Baker.
