Ciunpijloinyza ordinaria, u. sp. (Plate V., tig. 5.) Male and 



female.' Antennae, 0012 ; wings, 0-063 x 0-029 ; body, 



0-052 X 0-007. 



AntenniB light-brown, 2 + 10 joints ; first joint of scapus 

 large, globose, second much smaller ; lowest joint of flagel- 

 lum lighter than the rest, oval, others subglobose, with pedi- 

 cels about half their length ; ornamented with numerous 

 verticils about twice as long as the diameter of the joints ; 

 terminal joint oval, much smaller than the rest. Thorax 

 dark-brown, with a few hairs. Scutellum semicircular, brown. 

 Halteres with a short pedicel bearing an elongated pyriform 

 club, light-brown in colour, and pubescent. Abdomen dark- 

 brown, ornamented with numerous brown hairs. Legs more 

 elongated than usual ; femora and tibiye robust ; very light 

 brown or pale-yellow, thinly clothed with rather long light- 

 coloured hairs. Wings mther smoky, clothed with rather a 

 thick covering of light-brown hairs. Slight rudnnent of 

 auxiliary vein; first longitudinal less than half the lengtli 

 of the wing, part beyond point of origin of transverse vein 

 about twice the length of the transverse vein ; second longi- 

 tudinal slightly curved, ending at the apex of the wing. Third 

 longitudinal indistinct, disappearing a little distance from the 

 margin ; fourth longitudinal mdistinct, anterior branch nearly 

 straight, reaching the margin, posterior branch nearly at right 

 angles to it, and disappearing close to the margin. 



Two specimens, one male and one female. Lincoln, Feb- 

 ruary. 



Genus Lestremia, Macquart. 



Antennte moniliform, verticillate, in the male 2 + 14, in the 

 female 2 + 9 to 2 + 10 jointed ; the joints in the male 

 almost ovate, pedicelled ; in the female more cylindrical, 

 with short pedicel?. Wings large, moderately broad, 

 with prominent posterior angle. First longitudinal vein 

 very short : secoiid longitudinal short, running rather 

 close to costa, joining the border much before the apex of 

 the wmg ; third longitudinal vein with a very long fork ; 

 cross-vein small beyond the middle of the first longitudinal 

 vein . 



Skuse records no species from Australia, but says the 

 genus is represented by a few /American and European species. 

 There seems to be some doubt as to whether ocelli are pre- 

 sent in the European species. As shown in Plate VI., fig. 4, 

 three ocelli are always present in the New Zealand species. 



Lestremia nooce-zealandice, n. sp. (Plate VI., fig. 1.) Female. 

 Antennae, 0-033 (largest), 0-014 (smallest) ; wing, 0-126 x 

 0-050 (largest), 0071 x 0-028 (smallest) ; body, 0-122 x 

 0-022 (largest), 0-060 x 0-014 (smallest).
