posterior border of the wing. First longitudinal less than 

 one-half the length of the wing; second longitudinal arcuated 

 at the tip, ends slightly beyond the apex ; anterior branch of 

 third longitudinal very indistinct ; transverse vein situated 

 less than half-way along the first longitudinal. 



I have two specimens, taken at Lincoln during November. 



Diplosis scoparia,i\.s^. Female. Antennae, 0-036 ; wings, 

 0-088 X 0-038 ; body, 0-059 x 0-012. xVntennse dark-brown ; 

 joints about twice the length of their pedicels, cylindrical 

 in shape, but slightly constricted in the middle ; verticils 

 short and scattered ; terminal joint of the antennse bears a 

 pointed projection at its end. Palpi pink. Thorax dark- 

 brown, with two narrow pink stripes, widely separated at the 

 anterior end, but converging considerably towards the scu- 

 tellum ; a few hairs on the lateral margins and on the pink 

 stripes. Scutellum pink, with a row of hairs on its semicircu- 

 lar posterior margin. Halteres with long slender red pedi- 

 cels, bearing a pyriform club clothed rather thickly with black 

 hairs. Abdomen bright-pink, the posterior margins of the seg- 

 ments, as usual, bearing a few long hairs. Legs dark-brown ; 

 femora and tibiae about equal in length ; joints of the tarsus 

 as in D. fragilis. Wings smoky, rather thickly covered with 

 a brown pubescence. First longitudinal rather less than half 

 the length of the wing ; second longitudinal at first straight, 

 but afterwards strongly arcuated, ending considerably beyond 

 the apex ; fork of third longitudinal slightly beyond the end 

 of first longitudinal ; cross-vein situated less than half-way 

 along first longitudinal. 



I have two female specimens of this insect, which were 

 taken at Lincoln in November. 



Diplosis wanganuicnsis, n. sp. (Plate VII., fig. 2.) Female. 

 Antenna, 0049 ; wings, 0-096 x 0035 ; body, 0071 x 0-014. 

 Antennae dark-brown ; joints of the scapus dull-yellow, nearly 

 orbicular ; basal joints of the flagellum more than double the 

 length of those near the apex ; basal joints much more, and 

 apical joints slightly more, than double the length of their 

 pedicels ; terminal joint with a small projection ; verticils 

 small and scattered. Palpi the same colour as the joints of the 

 scapus, as long as the antenna? up to the first joint of the 

 scapus. Thorax ferruginous, with two converging light lines ; 

 perfectly glabrous. Scutellum ferruginous, without hairs. Hal- 

 teres with long slender white pedicels, the clubs being darker 

 owing to the presence of black hairs. Abdomen pink, with 

 long slender ovipositor ; very few hairs on the segments. 

 Legs light -brown, long and slender, very slightly hairy. 

 Wings pellucid, glabrous, or slightly hairy. Costa and second 

 longitudinal light-red ; first longitudinal a little more than
