626 Mr. F. W. Edwards on new 



darkened in the middle. Pleura with obscure brown 

 niottlin^^, a rather conspicuous dark spot on the sternopleura. 

 Abdomen, dark brown dorsally, each of tergites 2-^ with a 

 rather narrow oblique white mark on each side, commenc\ing 

 from the basal corner and extending a little over half the 

 length of the segment ; tergites 1 and 7 with a somewhat 

 similar but more ochreous mark. Hypopygium dark brown, 

 constructed as in the other New Zealand species. Legs 

 yellowish, the tips of the femora, tibiae, and tarsal segments 

 dark brown, most conspicuous on the femora. Hair rather 

 long and conspicuous, about twice as long as the diameter 

 of the segments. Wings with the ground-colour whitish, 

 except in cells G and Sc^ where it is more ochreous, the 

 greater part of the surface covered by the dark brown 

 markings ; veins yellowish, darker in most of the dark areas, 

 all except Sc^ An, and the cross-veins clothed with rather 

 conspicuous macrotrichia. Markings much as in T. forci- 

 patus^ O.-S., but the borders of all the large spots are 

 darkened, and in many places traces of the white ground- 

 colour show between the spots and the dark borders. 



Venation : the two accessory cross-veins separated by less 

 than the length of one of them, both placed well beyond the 

 fork of i^2+3« Cross-vein m angulated, each half about as 

 long as the basal section of M^. Cell it/g not much wider at 

 the margin than cell M^, Halteres pale basally, knob dark 

 brown. 



Length of body 15 mm.; wing 17x5 ram.; front leg 

 33 mm. 



North Island : in dense forest, ravine below reservoir, 

 Wainui-o-mata, Wellington, 15. xii. 1920 {G. V, Hudson). 



Type ^ (unique) in Mr. Hudson's collection. 



Amphineurus sub^laber, sp. n. 



Closely related to A, horni^ Edw., differing as follows : — 

 Wings rather broader and with a slight yellowish tinge ; 

 macrotrichia on membrane very few and scattered, quite 

 absent from the greater part of the wing. Hypopygium : 

 ninth tergite with the apical lobes short, divergent, not 

 blackened. Side-pieces with two pairs of terminal processes 

 (apart from the appendages), which are equal in length and 

 about twice as long as the side-piece itself ; the outer process 

 hairy, of the usual form, the inner one (produced from the 

 ventro-apical angle) bare, blade-like, somewhat expanded 

 before the tip, which is acuminate. One pair of appendages 

 short, bent inwards at the middle, the outer half blackened ; 

 the other pair long, basal half swollen^ black, the outer third
