tudinal vein straight or slightly curved, going nearly to the 

 apex of the wing. Costal vein sometimes extending a little 

 beyond the tip of the third longitudinal. Posterior branch of 

 the fifth longitudinal straight or a little bent. Legs uni- 

 coloured, or only darker at the articulations. Fore meta- 

 tarsus considerably shorter than the tibia. Forceps of the 

 male slender" (Skuse). 



In the New Zealand species, here described, the thorax is 

 not striped. 



Orthocladius publicus, sp. nov. 



Male. — Uniform dull-brown, the legs rather paler. The 

 fore tibia not much longer than the metatarsus. Abdomen 

 and legs with distant hairs. Halteres brown. Wings pale- 

 brown, unspotted, the veins brown. The third longitudinal 

 vein nearly straight and joining the costa considerably before 

 the tip of the wing, the costa not produced beyond it. Fork 

 of the fifth longitudinal lies outside the cross-vein. The 

 fourth longitudinal ends at the apex of the w 7 ing. First longi- 

 tudinal ends nearer to the cross-vein than to the tip of the 

 third longitudinal. Length, If mm. ; wing, 2 mm. 



Female. — The long hairs on the legs are absent.

Orthocladius cingulatus, sp. nov. 



Male. — Dark, shining, brown; the sides of the thorax, 

 distal ends of the coxae, halteres, and anterior portions of the 

 second, as well as of the fourth and fifth abdominal segments, 

 pale-yellow. Legs pale-brown, with short close hairs. Abdo- 

 men with a few distant hairs. Fore tibia rather more than one 

 and a half times the length of the metatarsus. Wings hya- 

 line, the veins brown. The first longitudinal vein reaches the 

 costa abDut halfway between the cross- vein and the tip of 

 the third longitudinal. The third longitudinal reaches the 

 margin a little before the apex of the wing, and the costa is 

 produced slightly beyond it. The fourth longitudinal ends a 

 little below the apex of the wing. The fork of the fifth 

 longitudinal is nearly on a line with the cross-vein. Length, 

 3 mm. ; wing, 2^ mm. 



Hab. Christchurch (F. W. H.). 



Genus Camptocladius, V. d. Wulp, 1874. 



Antennae 14-jointed in the male, 7-jointed in the female. 

 Wings naked. Third longitudinal vein bent upwards, some- 

 times short and terminating considerably before the apex of 

 the wing, or running for some distance close along the 

 anterior margin ; consequently the first posterior cell is very
