Tipula maya, sp. n. 

 Large; thorax brownish-yellow, striped; wings brown; cross- vein r 

 before the fork of R2+3. 



9 Length, 28 min.; 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 — 5, 3.5 mm. 

 Head: Anterior prolongation of the front, and the palpi, dark 

 brownish-black. Antennae, basal segments brown, flagellum broken. 

 Front, vertex and occiput dark brown, occiput paler. 



Thorax: Pronotum dull yellow, the scutiun and caudal margin of 

 the scutellvun brown. A'lesonotum, pra;scutum dull brownish-yellow, 

 brighter, j-ellow, 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 imaer branch continuing directl}'- caudad in a line with the main 

 stem and rumiing 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 browm, dark brown 

 on the sides and on the caudal margin ; scutelliun dark brown medially, 

 the sides light brown, a narrow yellow stripe on the cephalic margin ; pos't- 

 notum dark brown with a pale narrow, median vitta. Pleurse 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 

 pleura;, under the root of the wing, fusing wth the dark browTi of the 

 postnotum. Hal teres dark browoi. Legs: coxce and trochanters light 

 yellow; femora light yellowish brown, tip broadly and abruptly dark 

 brown; tibia light bro\\m, the tip indistinctly darker; tarsi light browTi, 

 the tips o the individual segments dark Ijrown. Wings: Uniformly 

 suffused with bro^Ti; cells C and Sc more yellowish-brown; stigma 

 brown; cell 2nd Ri, Ro and tip of R3 darker brown; a brown seam on 

 most of the veins and a bro\vn cloud in cell M at about four-fifths the 

 length of Cui. Venation, (sec Fig. a); Rs long, gently arcuated, twice 

 as long as R2+3 before r; about as long as the basal deflection of Cui; 

 R2+3 straight, R2 about two-thirds as long as R2+3. The radial cross-vein 

 connects Ri with R2+3 before its fork, this distance on R24.3 between r 

 and the fork about equal to the cross-vein r-m. Basal deflection of 

 Rj+5 a trifle longer than r-in; cross-vein tn about twice as long as r-m; 

 cell 1st M2 about pentagonal, its inner face (segment one, Mi+s) about 

 as long as the cephalic face (segment two, M1+2) ; cross-vein m-cu oblit- 

 erated by fusion. Petiole of cell Mi about as long as this cell. Cu2 about 

 as long as the deflection of Cui. 



Abdomen: Tergum, seginent 1, yellowish on basal half, dark 

 bro\\Ti on caudal half and on the sides; segment 2 deep reddish-brown 

 with an indistinct dark brown median stripe and lateral margins; in the
