HuTTON. — 0)1 the Crane-flies of Neio Zealand. 25 



second joint small, the inner edge slightly dentate and ending 

 in a minute, dark, horny tooth. The lower pair smaller, claw- 

 shaped, with a free lobe on the inner side. Ovipositor long 

 and pointed. Length, $ 28 mm., 5 38 mm. ; wing, 3^ 30 mm., 

 5 31mm.; antennae, <? 3 mm., ? 3 mm. 



Hab. Wellington (Hudson). 



Although this species has a short rostrum, a sessile second 

 posterior cell, and a long terminal joint to the palpi, it is not 

 a true Pachyrhina, on account of the position of the posterior 

 ■cross-vein and the long praefurca, in both of which it re- 

 sembles Tipula. As, however, there appear to be several 

 other species intermediate between these two genera, it will 

 be advisable to retain ours in Pachyrhina until a revision is 

 made by some one who can examine a large collection from 

 all parts of the world. 



The antennae and male forceps appear to be peculiar, 

 unless in the latter the lower pair of appendages are the 

 " large foliaceous appendages " described as occurring in 

 Longurio. 



Genus Tipula, Lmneeus (1740). 



Eostrum longer than the head, with a distinct nasus. 

 Antennas simple, short in both sexes. Terminal joint of the 

 palpi long and flagelliform. Discal cell receiving the posterior 

 cross-vein at its outer posterior angle ; second posterior cell 

 petiolate ; second longitudinal vein not sinuated. Genitalia 

 protruding in both sexes ; forceps of the male moderately 

 thickened. 



The species novarcB and fulva form a section which has 

 perhaps as much claim to generic distinction as has Holorusia. 

 Also orion, dux, clara, and tenera form another group of 

 closely allied species.
