new Tipulid* from the Malay Peninsula. 359 



antennae reddish-brown ; flagellum black, the joints oval, 

 with long hairs. Thorax almost uniformly shining blue- 

 blacky tinged with brown on the sides of the mesonotum. 

 Pronotum well developed, but not to the same extent as in 

 typical Teucholabis. Abdomen uniformly dark purplish, 

 somewhat shining. Hypopygium, fig. 4. Legs dark, clothed 

 with dark purple scales, a narrow ring of yellow on the 

 apical third of each femur ; the femora are not clubbed, but 

 gently and slightly enlarged towards their tips. Wings 

 whitish hyaline, with three complete dark brown fasciae, the 

 first well before, the second immediately beyond the middle, 

 the third occupying rather more than the apical fourth of 

 the wing ; the first fascia is nearly or quite connected with 

 the second by a median projection in cell M; the second .has 

 its distal margin irregularly concave, and between it and the 

 third is a squarish dark brown spot over the apex of cell 

 1st Mj. Venation : Rg present, short, ending exactly in the 

 tip of Rj ; Rs arising before one-third of the wing-length, 

 not at all curved at its base ; marginal cross-vein situated 

 on R2 a little beyond its base ; cell 1st Mg about twice as 

 long as broad, scarcely narrowed at the base, the three veins 

 at its apex equidistant ; R-M cross-vein joining Mj^g a little 

 beyond its base ; Cu^ meeting M3 near base of cell 1st Mg. 

 Halteres black, tip of knob white. 



Length of body 6 mm. ; wing 6 mm.

The genus Gymnastes was founded by Brunetti in 1911 for 

 G. violaceus, Brun. (= Teucholabis cyanea, Edw.), the author 

 differentiating it from Teucholabis chiefly on the absence of 

 a distinct neck and the clubbed femora. Neither of these 

 characters being of much value, Alexander proposed to sink 

 Gymnastes in Teucholabis, a course which the writer was 

 till now inclined to favour. G. cyaneus, however, shares 

 with the present new species the very peculiar character (for 

 a Tipulid) of having the legs covered with scales; and this, 

 together with some other minor characters, such as the 

 reduced neck and the colour of the halteres, will perhaps 

 serve to keep Gymnastes distinct. The apparent gulf 

 between G. cyaneus and G. pictipennis with regard to 

 neuration is bridged by Gnophomyia ornatipennis, de Meij,, 

 which is almost identical with G. cyaneus in colouring and 

 yet has R2 present, and in much the same condition as in 

 G. pictipennis. A specimen of an undescribed Japanese 

 species or variety closely resembling G. ornatipennis is in 

 the British Museum collection, and shows the same scales 

 on the legs as in G. cyaneus and G. pictipennis. I have,
