and third posterior cells and in the anal cell, these spots being 

 more or less bordered with brown ; a dark-brown mark on 

 the cross-veins. Auxiliary vein indistinct. Third longitudinal 

 considerably curved near the tip. meeting the costa a little 

 before the apex of the wing. Marginal cross-vein joining 

 the first longitudinal below its tip. Both branches of the 

 fifth longitudinal strong, the posterior meeting the margin 

 of the wing at right angles. Length, 3 mm. ; wing, 4-J mm. 



Female. — Abdomen greenish-brown. Wings without irides- 

 cent spots. Brown spots on the cross-veins, at the tips of the 

 longitudinals, and near the apices of the first posterior and

Tanypus malus, sp. nov. 



Male. — Head brown ; the antennae tawny, with pale-brown 

 plumes. Thorax tawny, with two brown median stripes, and 

 a spot on each side, the median bands nearly broken by a 

 tawny curved streak. Scutellum dark-tawny. Metanotum 

 dark-brown. First five segments of the abdomen white, with 

 brown marks on the anterior portion ; the rest brown. Legs 

 almost white, with dark articulations and dark median bands 

 on the tibiae and metatarsi. Fore metatarsus about two-thirds 

 the length of the tibia. Halteres white. Wings hairy, 

 white, with many small dark spots. Third longitudinal not 

 much curved, joining the costa considerably before the apex of 

 the wing. Marginal cross-vein very short, joining the costa. 

 Fourth longitudinal rather weak. Posterior branch of the 

 fifth longitudinal meeting the margin of the wing at right 

 angles. Length, 4 mm. ; wing, 3 mm.

Family TIPULIDvE (brevipalpi). 

 Genus Bhypholophus, Kolenati, 1863. 



"Two submarginal cells; four posterior cells; discal cell 

 present or absent. Wings pubescent on the whole surface. 

 The second longitudinal vein originates at a more or less acute 

 angle before the middle of the anterior margin ; the subcostal 

 cross-vein is at a considerable distance (two or three lengths 

 of the great cross-vein) anterior to the tip of the auxiliary 

 vein. Antennae 16-jointed. Tibiae without spurs at the tip ; 

 ungues smooth on the under-side; empodia distinct" (Osten- 

 Sacken). 



This genus differs from Molophilus and Erioptera in having 

 hairs all over the surface of the wing, instead of on the veins- 

 only.
