median notch and smaller lateral notches, separated by conspicuous 

 blackened teeth. Ninth pleurite complete, the outer angle produced 

 into a conspicuous, black, curved horn that is directed dorsad and 

 slightly proximad. Ninth sternite with only a slight median notch, 

 bearing a small lobe. Eighth sternite unarmed. 



Habitat: Formosa. Holotype, cf , Funkiko, April 21, 1917

Tipula formosicola sp. n. 



Generally similar to Tipula nova Walker; head brown, palei adjoining 

 the eyes; antennas indistinctly bicolorous; wings dark brown, more 

 grayish posteriorly, with a hyaline cross-band beyond the stigma, 

 extending to beyond cell 1st M2', cell R5 entirely clear; cell M hyaline 

 with a large brown area near midlength and another at the outer end; 

 abdomen rather long and slender; ovipositor with the valves slender, 

 smooth. 



Female — Length, 25 mm.; wing, 19 mm.; abdomen alone, 21 mm. 



Frontal prolongation of the head and palpi dark brown. Antennae 

 with the first scapal segment grayish pruinose; second segment pale; 

 flagellar segments yellowish, slightly darker basally, to produce a 

 bicolorous effect. Head dark brown, paler on the vertical tubercle 

 and adjoining the inner margin of the eyes. 



Mesonotal praescutum buffy, with three dull brown stripes that are 

 confluent, except behind near the suture; humeral region pale; a slightly 

 darker, capillary median line that extends to the anterior margin of the 

 praescutum; scutum buffy, each lobe with three brown spots; scutellum 

 and postnotum grayish, the median area extensive, brown. Pleura 

 grayish pruinose. Halteres comparatively long and slender, dark 

 brown, the base of the stem abruptly and conspicuously yellowish. 

 Legs with the coxae light brown, light gray pruinose; trochanters yellow- 

 ish, faintly gray pruinose; remainder of the legs broken. Wings dark 

 brown, variegated with subhyaline, the anal cells light gray; the dark 

 brown areas include the broad costal margin, extending caudad almost 

 to M and reaching the still darker brown stigma which completely 

 fills cell 2nd Ri and the outer half of 1st Ri; wing- tip in the outer half 

 of cells R2 and R3 dark brown; the subhyaline areas appear as a broad, 

 transverse band beyond the stigma, occupying the basal half of cells 

 R2 and Rs, all of R5, 1st M2 and the bases of Mi, 2nd M2 and M^; these 

 posterior cells are pale gray, only slightly darker than their subhyaline 

 bases, but the color deepens in the anal cells of the wing; cell M is 

 subhyaline with the apex and a cloud near midlength brownish; veins 

 dark brown, those beyond the cord narrowly seamed with dark brown. 

 Venation: Rs much longer than /?2+3; '' shorter than R2 beyond it; 

 petiole of cell Mi a little longer than m; m-cu distinct.
