Mesonotum clear yellow, .unmarked, scutellmn and median area of 

 scutum almost white. Pleura concolorous. Halteres pale, the knobs a 

 little darker. Legs with the coxae and trochanters pale, tinged with 

 green; remainder of legs pale, the terminal tarsal segments dark 

 brown. Wings nearly hyaline, iridescent, the veins strongly tinged 

 with green, especially the outer end of costa. Venation: Sc short, Sci 

 ending far before the origin of Rs, the distance being nearly, if not 

 quite, twice Rs; Sc^ apparently lacking; Rs short, subobsolete, entirely 

 without macrotrichiae, subequal to, or shorter than, the deflection of 

 i?4+5; cell 1st Mo closed; basal deflection of Cu\ before the fork of M. 



Abdomen pale brownish yellow, unmarked; in the female, the 

 basal segments are infuscated but this is apparently due to dried egg- 

 masses within the body; ovipositor reddish, the bases of the valves 

 tinged with green. 



Hab. New Zealand (South Island). Holotype, cf, Nelson, 

 November 8, 1920 {A. Philpott). Allotopotype, 9, October 23, 

 1920. Paratopotype, 9 , October 23, 1920. 



Type in the collection of the Cawthron Institute. 



In its general appearance, D. subviridis is strikingly like 

 D. conveniens (Walker), a very different fly. It belongs to the 

 monilicornis group, distinguished by the short subcosta, very 

 short sector and closed cell 1st Mo. 



Dicranomyia sperata, sp. n. 



General coloration obscure brownish yellow; head dark 

 brownish black; wings whitish subhyaline with conspicuous 

 pale brown washes, the most conspicuous at the wing-tip; 

 Sc long; r long and strongly arcuated; cell 1st M^ long and 

 narrow, the basal deflection of Cu\ at the middle of its length. 



Female. — Length 9 mm. ; wing 10.5 mm. Described from an 

 alcoholic specimen. 



Rostrum and palpi dark brown. Antennae dark brown, the second 

 scapal segment a little paler. Head dark brownish black. 



Mesonotum light brownish yellow, the praescutum with three 

 slightly darker brown stripes; scutal lobes also darker brown; scu- 

 tellum more yellowish. Pleura obscure yellow, the mesosternum faintly 

 darkened. Halteres obscure yellow, the knobs dark brown. Legs light 

 brown, the femoral bases a little lighter, the terminal tarsal segments 

 dark brown. Wings whitish subhyaline with conspicuous pale brown 

 washes; cells C and Sc light brown; a brown wash along vein Cu and 

 another near midlength oi 1st A ; anal angle of wing faintly darkened ; 

 cord and outer end of cell 1st M2 narrowly seamed with brown; stigma 

 elongate, brown; the most conspicuous brown wash occupies the wing- 

 tip beyond cell 1st M2 including about the outer half of cells £nd Ri and 

 R3; all except the base of R-o, all of Snd Mi; the cephaHc half of If 3;
