Tipula maya, sp. n. 
Large; thorax brownish-yellow, striped; wings brown; cross-vein r 
before the fork of Ro43. 
Q Length, 28 mm.; wing, 27.6 mm. 
Fore leg, femur, 14 mm.; tibia, 16.8 mm. 
Middle leg, femur, 15.9 mm.; tibia, 15.4 mm. 
Hind leg, femur, 16.2 mm.; tibia, 18.7 mm.; tarsus, seg. 1, 18 
mm.; seg. 2, 4 mm.; seg. 3—5d, 3.5 mm. 
Head: Anterior prolongation of the front, and the palpi, dark 
brownish-black. Antenne, basal segments brown, flagellum broken. 
Front, vertex and occiput dark brown, occiput paler. 
Thorax: Pronotum dull yellow, the scutum and caudal margin of 
the scutellum brown. Mesonotum, preescutum dull brownish-yellow, 
brighter, yellow, along the lateral margin of the sclerite; extreme 
cephalic margin of the sclerite dark brown, continued backward as a 
narrow median stripe broadening out in the middle but soon becoming 
faint and almost obsolete; the lateral stripe begins at the front angle, 
continues caudad; at about one-third the length of the sclerite it forks, 
the inner branch continuing directly caudad in a line with the main 
stem and running to the transverse suture; it is palest medially, the 
edges brown. The outer branch bends toward the edge of the sclerite 
and continues back to the side of the scutum; scutum brown, dark brown 
on the sides and on the caudal margin; scutellum dark brown medially, 
the sides light brown, a narrow yellow stripe on the cephalic margin; post- 
notum dark brown with a pale narrow, median vitta. Pleure very pale 
brown except the dorsal edge which is yellow; a dark brown band 
extends from the cervical sclerites across the dorsal portions of the 
pleurz, under the root of the wing, fusing with the dark brown of the 
postnotum. Halteres dark brown. Legs: coxe and trochanters light 
yellow; femora light yellowish brown, tip broadly and abruptly dark 
brown; tibia light brown, the tip indistinctly darker; tarsi light brown, 
the tips o the individual segments dark brown. Wings: Uniformly 
suffused with brown; cells C and Sc more yellowish-brown; stigma 
brown; cell 2nd Ry, Re and tip of Rs darker brown; a brown seam on 
“most of the veins and a brown cloud in cell M at about four-fifths the 
length of Cu. Venation. (see Fig. a); Rs long, gently arcuated, twice 
as long as Rey; before 7; about as long as the basal deflection of Cu; 
Ro,3 straight, Re about two-thirds as long as R43. The radial cross-vein 
connects R; with Re,3 before its fork, this distance on Re,3 between r 
and the fork about equal to the cross-vein r-m. Basal deflection of 
R45 a trifle longer than r-m; cross-vein m about twice as long as r-m; 
cell Ist Mz about pentagonal, its inner face (segment one, Mj.) about 
as long as the cephalic face (segment two, M142); cross-vein m-cu oblit- 
erated by fusion. Petiole of cell M; about as long as this cell. Cuz about 
as long as the deflection of Cun. 
Abdomen: Tergum, segment 1, yellowish on basal half, dark 
brown on caudal half and on the sides; segment 2 deep reddish-brown 
with an indistinct dark brown median stripe and lateral margins; in the
