This species is closely related to Tijntla soror, Wiedemanu, but the 

 general coloration is much more yellowish, and the details of the wing- 

 pattern and the male hypopygium are slightly different. 



TIPULA JOCOSA, Alexander. 



The male sex of this handsome crane-fly has not been described, and 

 the single specimen in the present collection is made the allotype. 



Male. Length 17'5 mm. ; wing 18 mm. ; fore leg, femur 1T6 mm., 

 tibia 14'8 mm. ; middle leg, femur 12 mm., tibia 13 mm. 



Similar to the type female except as follows : 



Antennae with both scapal segments yellow, the first flagellar 

 segment yellowish-brown ; remainder of the antennae dark brownish- 

 black ; antennae moderately elongated, if bent backward extending 

 about to the wing-root. 



Mesonotal postuotum blackish, heavily grey pruinose except behind. 

 A narrow dark brown line extending from the postuotum obliquely 

 forwards across the pleura, traversing the mesepimeron and the 

 mesosternum, ending behind the fore coxa. Pleura pale, whitish or 

 yellowish pollinose. Legs with the outer faces of the fore and hind 

 coxae a little darkened basally. Venation as in the type female, the 

 fusion of C^l l and M^-\- 4 much longer than r-m but shorter than m. 



Abdomen much darker coloured than in the female, the basal tergites 

 yellowish ; tergites 2 to 6 broadly dark brown apically with a broad 

 silvery basal ring ; tergites 7 and 8 paler, yellowish-brown ; sternites 

 pale, the ninth sternite blackish. Male hypopygium (Plate IV, fig. 28) 

 enlarged, the sclerites of the ninth segment fused into a continuous 

 ring that is interrupted only on the mid-ventral line. Eegion of the 

 ninth tergite (Plate IV, fig. 27) large, ample, the posterior margin 

 concave, the lateral angles slightly produced into thin, heavily 

 chitinised shiny lobes, the median area produced ventrad and slightly 

 caudad into a pendulous pale fleshy lobe that is densely clothed with 

 a fine pubescence. Eegiou of the ninth pleurite ample, with a 

 flattened obtuse tooth veutrad of the lateral angles of the tergite. 

 Pleural appendages dark coloured, the outer appendage a small, 

 elongate-cylindrical, sparsely hairy lobe; inner appendage small, heavily 

 chitinised, the apex produced into a cylindrical beak that is directed
