ended as in P. scalator. Legs with the coxre and trochanters 

 bright orange, the femora orange with the tips rather 

 narrowly black; tibise and tarsi almost black. Front and 

 middle femora with short black pubescence, hence appearing 

 dark ; hind femora with almost entirely orange pubescence, 

 which on the inner side of basal half is very long and dense 

 (as in males of the very differently coloured P. divisa, Brun., 

 and P. speciosa, Edw.). Hind tibia; with a rather narrow 

 yellowish ring near the base. Wings resembling those of 

 P. scalator (see PI. X. figs. 13 & 14) in their black and 

 yellow pattern, but all the apical cells of the wing are con- 

 spicuously yellow basally in their centres. Rs conspicuously 

 spurred near base ; cell Mi rather broadly sessile ; cells Cui 

 and Cu2 of equal breadth at the margin ; m-cu distinct. 

 Halteres orange ; knob with a black spot at the base above. 



Length of body 17 mm. ; wing 15x5 mm. 



Formosa : Taito, 25. ii.-27. iii. 1919 {S. Inamura, 

 J. Sonan, M. Yoshino), 1^. Related to P. scalator, Alex., 

 differing chiefly in the hypopygium and hind femora. 



DOLICHOPEZINI. 



Dolichopeza sp., of. orientalis, Brun. 

 Fauna Brit. Ind., Nematocera, p. 354 (1913). 



Formosa : Ringaurin, Nan to, 18. xii. 1916 {T. Shiraki), 

 IcJ. Very similar to D. orientalis, Brun., but probably 

 distinct, the white on the legs being less extensive. The 

 specimen, however, is too damaged for purposes of 

 description.

Tipula flavicosta, sp. n. (PI. X. fig. 15.) 



Head ash-grey, with a narrow black median line ; sides of 

 rostrum and palpi black. Nasus short, simple. Antennae as 

 long as the thorax, with the first three joints pale ochreous, 

 the rest black. First flagellar joint nearly twice as long as 

 the second, slightly longer even than the first scapal, nearly 

 cylindrical ; remaining flagellar joints (except the small 

 terminal one) all about equal in length, very slightly 

 enlarged at the base ; verticils shorter than the joints. 

 Thorax almost bare, ash-grey; prrescutum with three slightly 

 darker stripes, the middle one divided by a dark line ; 

 scutellum and postnotum dark grey. Abdomen somewhat 

 shining, dark brownish, the last few segments almost black,
