In both sexes the wings are clear, the veins brown, and 

 the posterior cross-vein is slightly sinuated. The eyes are 

 slightly hairy ; the arista is shortly pubescent. The third 

 joint of the antennas is about one a half times the length of 

 the second ; the facial ridges are bare. 



Trichophthicus ordinatus, sp. nov. 



Frontal band black, margined with white, which extends 

 over the face ; antennas piceous. Thorax grey, with three 

 long broad black bands ; scutellum grey, the sides and a spot 

 at the base black. Abdomen grey ; the first segment black ; 

 the second, third, and fourth with a large triangular black 

 spot on each side which nearly meet in the middle on the 

 fourth segment ; fifth segment with a central black band, 

 which extends to the apex. Legs black. Squamae slightly 

 brownish. Wings pellucid, the veins blackish ; the chief 

 cross-vein slightly margined with brown ; the posterior cross- 

 vein slightlv sinuated. Length, 8-9 mm. ; wing, 7-8 mm. 



Hab. Wellington (G. V. Hudson). 



The third joint of the antennae is four or five times the 

 length of the second. The eyes are rather nearer in the male,, 

 and more hairy, than in the female. The facial ridges are 

 strongly ciliated for the greater part of their length.

 larger than the antisquarnae. Sixth longitudinal vein not 

 reaching the margin of the wing.

Frontal band brown, margined with white, which colour 

 extends over the face. Thorax pale-grey, with five longi-

The facial ridges, as well as the eyes, are bare ; the second 

 joint of the antennae is rather long ; the third about one and 

 a half times the length of the second ; arista minutely pubes- 

 cent. The first posterior cell gradually widens to the margin:
