HuTTON. — On the Crane-flies of Neru Zealand. 23 



Skuse's papers on the Australian TipulidcB, in the " Proceed- 

 ings of the Linnaeau Society of New South Wales " for 1889 

 and 1890, and by Baron Osten-Sacken's " Studies," which he 

 was good enough to send me. 



All the New Zealand species of Tipulidcs as yet described 

 are endemic, while all the genera except two — Tinemyia and 

 Tanyderus—Qxe found in Australia, and it is probable that 

 these two will be found there in due course. Tanyderus is 

 found in Chili and Amboina ; Macromastix in Australia and 

 Chili ; Gynoplistia is limited to x\ustralia. New Guinea, and 

 Celebes ; and Cerozodia to Western Australia. The other 

 twelve genera have a wide distribution. 



Family TIPULID^. 



Legs very long and slender. The head prolonged for- 

 wards into a rostrum, which is often provided with a sharp- 

 pointed nasus. Ocelli nearly always absent. Mesonotum 

 generally with a V-shaped transverse suture. The basal cells 

 of the wings elongated, almost always reaching beyond the 

 middle of the wing ; a discal cell in most of the genera. 

 Ovipositor generally with two pairs of horny pointed valves.

absent . . . . . . . . . . TiptdincB.

V-shaped suture, indistinct or absent. . .. .. PtychopterincB. 



Sub-family TIPULIN^. 



The tip of the auxiliary vein turns backwards and joins 

 the first longitudinal ; sometimes it is blended with the 

 first longitudinal, and therefore apparently absent. No sub- 

 costal cross-vein. The first longitudinal ends in the second, 

 and is connected near its tip to the costa by a cross-vein. 

 Last joint of the palpi long and flagelliform, generally longer 

 than the other three taken together.

" Anterior branch of the second longitudinal vein entirely 

 wanting, consequently there is no rhomboid cell. Prsefurca 

 extremely short, often almost vertical. Discal cell wanting ;
