142 M BLANDER AND BRUES. [VOL. I. 



light yellow, narrowly margined with black, fringed with dark hairs, inner and 

 apical angle prolonged into several long filaments. Pleurae glaucous, in differ- 

 ent parts green, cupreous or piceous, according to angle of vision. Middle 

 and hind coxae piceous, glaucous. Fore coxae yellow, piceous and dusted 

 basally on posterior face ; front surface besides the strong apical bristles with 

 fine dark hairs which are supplanted by lighter ones on proximal portion. 

 Legs yellow except apex of hind tibiae, hind tarsi, and last two joints of 

 front tarsi. The middle and front tarsi increase in density of color from 

 tip of first joint. Hind femora not ciliated, with a subterminal bristle. 

 Hind tibiae not glabrous inwardly. Front tarsi slender, as are the tibiae, 

 nearly twice the length of the tibiae ; first joint longest, a little shorter than 

 two following ; second and third subequal, fourth shortest, fourth and fifth 

 together about equal to third ; fourth and fifth joints flattened. Empodia 

 distinct, yellowish. Wings long, hyaline ; costa with a small tubercle at 

 juncture of first vein ; third vein converging towards fourth ; bend in fourth 

 vein slight ; at tip of fifth vein a broad, shallow sinus ; anal portion moder- 

 ately prominent. Tegulae and hal'teres yellow, the former with long black 

 cilia. 



One male taken by Mr. Clermont Livingston at Corfield, 

 Vancouver Island, May 21, 1896. 



Though closely related to discifer, it appears quite distinct. 

 The more evident points of difference are these : 



Pernix: First antennal joint not red beneath ; arista inserted 

 near middle of third joint of antenna; numerous dark hairs on 

 anterior face of fore coxae ; tip of hind tibiae evidently black 

 for some distance ; fourth tarsal joint flattened, black ; wings 

 not evidently narrowed at base. 



Discifer: First antennal joint reddish on under side ; arista 

 beyond middle of third antennal joint ; front coxae with white 

 hairs (dark hairs on inner side of female, only) ; hind tibiae 

 dark at only extreme tip and less on outer side ; fifth tarsal 

 joint only black; wings rather narrowed towards base. 



The proportion of the tarsi to the tibiae is also different, as 

 is also the comparative length of the tarsal joints. 



Dolichopus pantomimus, sp. nov. 



Green ; face narrow, light brown ; antennae black with simple arista ; 

 cilia of inferior orbit pale ; cilia of tegulae black ; feet yellow, includ- 

 ing front coxae and excepting tip of hind tibiae and tarsi, not ornamented 

 in the male excepting femoral brush ; fourth vein not broken.
