Tipula a3rmara, sp. n. 



Orange; costal margin of the wnngs dark; cross-veins not seamed 

 wilh browTi; radial cells light browTi. 



Length, cf ■ 15 mm.; wing, 17 mm.; antenna?, about 7.6 mm. 



Length, 9 ■ 13. S mm.; wing, 14.6 mm. 



Hind leg, cf ; fem. 10.4; tibia, 13.3; tarsus about 2.").") mm. 

 Hind leg, 9 ; fem., S; tibia, 9.6 mm. 



c^ Head: Anterior prolongation of front short, light brown; palpi, 

 segment one, shorter than two, brown; 3d about equal to 2d, dark brown 

 at base; pale, yellowish, at tip; 4th, very long, lash-like, twice as long as 

 the rest of tlie pal]xis together, yellow. Antenna?, segments 1 to 3 

 orange-yellow; remainder brown, with a fine white pul^escence; three 

 or four bristles at the base of each segment and a single one near the 

 middle. Front and vertex browni.sh-orange ; occiput l^rown; the vertex 

 very thickly beset wath numerous long hairs; this including the whole 

 region bounding the eyes, both above and beneath. 



Thorax: Collare orange. Pronotmn orange-yellow. Mesonotum, 

 prasscutum and scutum orange without distinct markings; scutellum 

 and jxjstnotum yellow. Pleurae and stemites clear yellowish-orange. 

 Halteres yellow, knob darker. Legs: coxae, trochanters and extreme

 the coxae thickly beset with long yellow hairs. Wings (see Fig. b) with 

 a pale browmish-grey tinge; cells C, Sc, most of 2d Ri light browai; the 

 distal half of cell 1st Ri dark brown, forming the stigma; no brown 

 seams on the cross-veins or deflections. Radial cells, indistinctly suf- 

 fused with very light brown distally; cross-vein r-m slightly margined 

 with brown. 



Abdomen: Tergum, 1st segment, yellow; 2d brown; 3d, 4th, dark 

 brown; 5th, 6th, lighter brown; 7th, 8th, black; the 1st to 5th tergites 

 are very deep, so that viewed from the side, they conceal the stemites; 

 the 6th stemite shows caudally, the 7th is one-third as high as the 7th 

 tergite, the <Sth stemite subequal to the Sth tergite. Sternum, seg- 

 ments one to five, invisible, 6, orange, 7 — 9, black. Hypopygitxm 

 (Fig. m). 7th stemite almost straight along the caudal margin; 7th 

 tergite, broad, its caudal margin almost straight, very feebly concave. 

 Sth stemite (from beneath), broad, the caudal margin wath an obtuse 

 median notch, the adjacent lobes broadly rovmdcd and clothed with a 

 dense brush of long yellow hairs; (from the side) (8s) with the dorsal 

 margin gently sloping; the tip trmicated. 8th tergite, (8t) reduced to a 

 mere strip, its caudal margin rather strongly concave so that the median 

 portion is scarcely visible. 9th stemite (9s) appearing as the half of an 

 oval, the outer face sub-shiny, convex, a .small group of long hairs on 

 its dorsal angle; the dorsal margin strongly bent cntad, the i^roximal 

 margin straight, almost in a line with the notch on the 8th sternitc, the 

 two together making a very deep V-shaped niche; the proximal-ventral 

 side is strongly protluced into a rectangular ann, projecting entad, its 

 tip strongly truncated, almost touching its fellow of the opposite side. 

 Looking into the end of the genital chamber (see Fig. mi) there appears
