examined under a high power 8 segments may be distinguished (fig. 5). 

 Manv sensory pits may be seen on these segments, especially toward the 

 out side. 



Face silvery tomentose except for a nude and black medio-longitudinal 

 stripe ; upon the tomentum, in certain lights, are a few black spots. Mouth- 

 parts tawny, completely withdrawn except for the apices of the palpi. 

 A few hairs around the oral aperture and longer posteriorly. 



Thorax on the dorsum shiny and dark reddish-purple, dusted with a 

 tawny tomentum ; humeri tawny ; pleurae shiny pitch-black with a faint 

 purplish reflection and short silvery down at times indistinct. Scutellum 

 and the 4 spines tawny. Halteres light yellow. 



Legs tawny, posterior femora thickened ; tarsi darker at the apex, 

 especially those of the anterior and middle legs, almost the whole of the 

 former velvet-brown. Length of tarsal joints as in preceding species. 



Wings (fig. 6) with costa straight along the costal cell'; anterior cross- 

 vein and 3rd longitudinal not having a common origin from the 2nd vein 

 but nearly so, the 1st submarginal cell being thus proximally acute. 

 Anterior cross-vein curved a little and slightly anteriorly oblique but not 

 short. The remainder of venation practically identical with that of apicalis. 

 A dark-brown band across the wing covering the marginal and discal cells 

 and becoming lighter toward the posterior margin ; both sides of this band 

 are irregular, and the apex of the marginal cell may be clear. Proximal 

 of the band the wing is faintly tinged with yellow, darker in the costal cell, 

 and the veins yellow ; between the band and apex the wing is faintly brown, 

 with brown veins. 



Abdomen beyond the middle broader than the thorax, of a shiny- 

 cupreous colour, with a distinct purplish tint, dusted with tawny, and bearing 

 yellow hairs at the sides. 



Genital organs represented by a pair of tawny and styliform appendages. 



?. Length, 8 m.m. ; wing, 7-5 mm. 



Hutton gives the length, apparently of both sexes, as 8-11 mm., and 

 wing 7-8 mm. I have not seen the male, and there are no specimens of 

 the species in Hutton's collection. 



Habitat.— Auckland (Hutton) and Southland, January (Philpott). 



E. seolforalis n. sp. 



A fly of moderate size. Wings unclouded and more or less pellucid. 

 Thorax of a brilliant green, and abdomen - — except for the first deeply 

 purple segment — covered by a dense silvery pubescence. The abdomen is 

 characteristic. 



Head broader than the thorax at the humeri ; eyes bare, dichoptic, 

 more so in ?, occupying most of head in profile, orbits angulated above 

 the antennae (more marked in o), facets of uniform size, no transverse 

 depression in either sex but in the $ a narrow bronzy belt ; in both sexe's 

 lower two-thirds of eye darker than the upper third. Front hairy, narrow, 

 of about equal width throughout, shiny black with a faint bluish tinge and 

 a patch of silvery tomentum just above the antennae, which are situated a 

 little below the middle line of head and not quite as long as the width ; 

 1st to 3rd joints dark brown with a thick pubescence ; 1st and 2nd joints 

 short, bristly, and of about equal length ; 3rd elongate, club-shaped, and 

 composed of 8 segments terminating in apical delicate hairs. 



Face hairy, silvery -tomentose with darker longitudinal reflections. 

 Proboscis hairy and tawny ; palpi darker with delicate hairs, the pen- 

 ultimate joint elongate and narrow, tawny, and about as long or a little
