THE CANADIAN ENTOMOLOGIST. 9 



34. Arciophila Harveyi, sp. nov. (Figs. 4, 4a.) 



Male. — Face yellow, with fine yellow pile; a shining black stripe 

 descends from the base of the antennas over the tubercle, which is quite 

 small, to join with the black shining oral margin and cheeks. Front 

 black, thickly whitish poUinose, and with short black pile. Antenna? 

 reddish, third joint quadrangular, the corners rounded ; arista basal, 

 plumose. The antennc^ are inserted on black ground. Vertex black, 

 shining, wiih black pile. Thorax and scutellum black, shining, covered 

 with a thick coat of pile, which is yellowish on the pleura and anterior 

 two-thirds of the thoracic dorsum, but jet black on the posterior third and 

 the scutellum ; a fringe of light pile projects from underneath the 

 scutellum behind. Abdomen black, shining, tip of the fourth segment 

 margined with red ; pile of the second segment black, that of the third 

 mixed black and yellowish, that of the remaining segments yellowish. 

 Legs black, knees reddish-brown, tips of tibiae and basal joints of tarsi 

 lighter ; pile of legs abundant, mostly black. Halteres piceous. Wings 

 hyaline, with an ill-defined, dilute brownish cloud about the base of the 

 submarginal cell j stigma yellow ; third vein entirely straight. 



Female. — Similar to the male in all essential respects. The pile of 

 the front and vertex is yellow, intermixed with a few black hairs on the 

 vertex. On the thorax the yellow pile extends back almost to the 

 scutellum. The legs are slightly lighter in colour. 



Length, 13 to 15 mm. 



Described from one male taken on Mt. Cheam, Aug. ir, 1903, and 



one female from Hope, July 12, .1906. Both specimens were taken by 



Mr. R. Valentine Harvey, after whom I take pleasure in naming the 

 species. 



The genus iVrctophila has heretofore been known in America by only 

 one species, A. flagrafis, O. S., and in Europe by two species, A. 

 bombiforinis^ Fallen, and A. ?fiussita?is, Fabricius. From all of these A. 

 Harveyi differs in having the third vein entirely straight. Otherwise it 

 conform.s closely to the generic description. A. Harveyi can be 

 distinguished at once iiomJlagra?is by the black pile of the thorax and by 

 the black facial stripe. 



35. Eristalis Meigenii, Weidemann. 



One female from Vernon, Sept, 9, 1904, and a male from the same 

 locality, Aug. 15, 1906, both taken by R. V. Harvey.
