anterior portion of each segment silvery. Legs dark-brown. 

 Squamae white. Wings pellucid, brownish at the base, the 

 two cross-veins and the bend of the fourth longitudinal 

 bordered with brown ; veins brown. Fourth longitudinal bent 

 sharply forwards at a right angle, and then outwards almost 

 at a right angle ; an appendix at the first bend ; the first 

 posterior cell distinctly open ; posterior cross-vein at right 

 angles. Length, ? 9 mm. ; wing, ? 6 mm. 



Rob. Christchurch (F. W. H.). Male unknown. 



The third joint of the antennae is rather longer than the 

 second, straight on the sides, and rounded at the end. Second 

 joint of the arista one-third or one-fourth the length of the 

 third. Facial ridges with a row of weak hairs. Head, 

 thorax, abdomen, and legs with strong black bristles. The 

 second abdominal segment has two pairs of discal setae ; on 

 the third and fourth segments they are irregular. The setae 

 on the third longitudinal vein are strong, and extend up to or 

 beyond the chief cross-vein. 



Calcager turbidum, sp. nov. 



Head yellowish-white ; eyes reddish-brown, bare. An- 

 tennae reddish-brown, the first and second joints with silvery 

 tomentum. Proboscis and palpi dark-brown. Thorax, scu- 

 tellum, and abdomen brownish-black, with some white to- 

 mentum on the anterior part of each abdominal segment. 

 Legs brownish - black. Squamae white. Wings pellucid, 

 without spot; the veins dark-brown. The fourth longi- 

 tudinal is bent sharply at an angle, which is slightly obtuse, 

 from whence it is nearly straight ; an appendix at the 

 bend ; first posterior cell distinctly open ; posterior cross- 

 vein oblique, parallel to the bend of the fourth longi- 

 tudinal. Length, $ 6-7 mm., $ 7-8 mm. ; wing, $ 5 mm., 

 2 5^-mm. 



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



The third joint of the antennae is about as long as the 

 second, slightly concave in front and convex behind. Second 

 joint of the arista between one-half and one-third of the third. 

 Facial ridges with a row of weak hairs. In the male all the 

 abdominal segments after the first have a row of marginal 

 setae, but in the female there are only two on the middle of 

 the posterior margin of the second segment. The setae on the 

 third longitudinal vein are strong, and extend beyond the 

 chief cross-vein. 



Section B. 



First posterior cell closed, ending rather before the tip of 

 the wing. Facial ridges bare. Setae on third longitudinal 

 vein weak. No cubital appendix.
