Milleh. — The Diptera Fan/in of New Zealand. 177 



The <$ genitalia consist above of a pair of short tawny claw-like hairy- 

 styles arising from a plate as in the ?, and beneath this plate is a pair of 

 stout claws being opposed to each other and each arising from a protube- 

 rance upon which they apparently articulate. 



S. Length, 7-12-5 mm. ; wing, 6-10 mm. 



$. Length. 14 mm. ; wing, 12 mm. 



Habitat.- — Throughout New Zealand, but more abundant in Auckland 

 than elsewhere. It is by no means often found as far south as Otago, and 

 is not as common in the South Island as in the North Island, except at 

 Nelson, where the climate is exceptionally warm. The principal localities 

 are Auckland. Napier. Wellington, and Nelson; and it is seen in the 

 months of December. January, and February. 



This species is common to Australia and New Zealand.

A medium-sized fly with clouded wings and a tawny abdomen dark at 

 the apex. 



Head a little broader than the thorax at the humeri ; eyes bare, 

 dichoptic, more so in the $ ; a faint emargination above the antennae, 

 very distinct in the $. In profile the eyes occupy the whole side of the 

 head. Front shiny black with a tinge of blue and a patch of silvery 

 tomentum just above the antennae, which are situated a little below the 

 middle fine of head ; about three-quarters the width of the head in <J and 

 fully one and a quarter times the head-width in $, being characteristically 

 elongated. As a rule the antennae project in front of the head, but in one 

 2 they are erect. First and 2nd joints bristly with a shorter pubescence, 

 the 3rd with a dense vestiture of short and stiff pubescence obscuring the 

 segmentation ; this joint is linear and almost of equal width throughout. 

 The 2nd joint and proximal portion of 3rd are tawny, the remainder dark 

 brown. The apex of the 3rd joint is of unique form : the penultimate 

 segment is truncated, from one corner of which some short and stiff hairs 

 project ; the opposite corner and the adjoining half of the anterior edge 

 of this segment are occupied by the base of the ultimate segment, which 

 is short and oval, terminating in some stiff hairs. Face with a silvery 

 pubescence, darker in certain lights, and with a dark medio-longitudinal 

 stripe. Mouth-parts tawny and withdrawn, the palpi apparently 2-jointed. 

 Occiput shiny black with a silvery tomentum. 



Dorsum dark violet-black, faintly purple in certain lights, and dusted 

 with a golden tomentum ; humeri tawny ; in some cases the dorsum is 

 more or less dark tawny, with a dark violet-black spot posterior to the 

 humeri and extending as a narrow stripe to the transverse suture. Pleurae 

 shiny violet - black, except the sternopleurae which are pitch - black. 

 Scutellum either tawny or dark tawny, tomentose, and with 4 tawny 

 spines. Halteres pale tawny. 



Legs tawny, the anterior tarsi fuscous except the proximal portion of 

 the protarsi which is tawny ; posterior femora thickened. The anterior 

 and middle protarsi are equal to the sum of the remaining tarsal joints,
