of vein M not toucliing the origin of Rs ; the band along 

 the cord that occurs in binotata is here much broken up^ 

 represented chiefly by a vague clouding cephalad of r-m and 

 a conspicuous dark brown spot at the fork of Cu. Venation: 

 cell \st M2 more elongate ; cell ilfi short-petiolate to sessile. 

 Second abdominal segment not yellow on the basal half. 



Hab. New Zealand (North Island). 



Holotype, S> Ohakune, altitude 2060 feet, July 19.21

Paratopotypes, S S S , with the type ; I S , May 17, 1922 ; 

 paratype, 1 S , Owhango, July 1, 1922 {T, R. Harris). 



Macromastix hnlterata, sp. n. 



General coloration dark brown ; antennse short ; halteres 

 very long ; wings strongly tinged with brown ; basal 

 deflection of Cui far before the fork of M ; abdominal 

 sternites bicolorous. 



Male. — Length 7 mm. ; wing 8*3-8'5 mm. 



Described from alcoholic material. 



Frontal prolongation of the head short, light brown ; 

 nasus lacking ; palpi short, pale brown. Antennae short, 

 pale brown, the basal flagellar segments narrowed basally, 

 a little produced apically on the ventral face^ the terminal 

 five segments elongate, cylindrical or nearly so, gradually 

 becoming more elongate to the end. Head dark brown, the 

 anterior part of the vertex paler. 



Mesonotal prsescutum dark brown with three yellowish- 

 brown stripes, the medial stripe further subdivided by a 

 capillary dark vitta ; remainder of mesonotum brown. 

 Pleura obscure brownish yellow, with no distinct markings. 

 Halteres very long and slender (2"5 mm.), brown. Legs 

 with the coxse concolorous with the pleura ; trochanters 

 a little darker ; remainder of the legs dark brown, the 

 extreme femoral bases paler. Wings with a strong dark 

 brown tinge, the stigma even darker brown ; obliterative 

 areas before the stigma and across the base of cell \st M^. 

 Wing-ba>:e subpetiolate, so the basal half of cell 2nd A is 

 very narrow. Venation : cell 2nd Ri small ; petiole of cell 

 Ml variable, from about equal to m to almost lacking ; basal 

 deflection of Cui before the fork of M, the fusion variable, 

 from about equal to m to almost at the fork of M ; fusion 

 of M3 and Cui about equal to the fusion of M and Cui. 



Abdominal tergites dark brown^ the sternites yellow, with 

 the bases of the segments narrowly infuscated.
