THE CANADIAN ENTOMOLOGIST. 21 



tibiae are not ornamented as in the male, and the wings are much lighter, 

 the brown forming a border to some of the veins. Length, 12-16 mm. 

 Los Angeles and San Bernardino Counties, California, and British Colum- 

 bia. Two males and three females, in May. The British Columbia 

 specimen was received from Mr. W. A. Danby. 



This species is closely related to A. senilis Bigot, but in the latter 

 species the wings are wholly hyaline, and the appressed white hairs on the 

 front tarsi of the male are confined to the first joint. I have specimens 

 of the latter species from Colorado and Florida (Morrison). In both 

 species, the colour of the bristles on the head, body and legs is too vari- 

 able to be of any value in separating the species. 



Anisopogon rubidus, n. sp. P . — Obscure brown, the following parts 

 black : — The third antennal joint, basal half of style, proboscis, palpi, 

 scutellum except its base, first segment of abdomen, basal half of second, 

 lateral margins of the others, seventh segment and genitalia largely, apex 

 of venter and upper side of each femur, that on the first and second seg- 

 ments of abdomen with a strong bluish tinge, brown of abdomen more 

 reddish than on the other parts ; thorax irregularly marked with grayish 

 black. Head gray pollinose, the pile yellowish-white ; face evenly con- 

 vex, the pile extending nearly to base of antennae ; first joint of antennae 

 slightly longer than the second; third joint slightly longer than the" first 

 two taken together, tapering gradually to the apex, the style two-thirds as 

 long as the third joint. Thorax gray and golden pollinose, the pile short, 

 sparse, mixed black and white ; pleura gray pollinose, its pile and that of 

 the coxae white, the fan-like pile in front of halteres also white. Pile of 

 abdomen sparse, microscopic, light-coloured, that on lateral margins and 

 on venter longer, whitish. Pile of legs sparse, whitish, that on tarsi and 

 tips of tibiae largely black. Wings smoky gray, all posterior cells and 

 the anal cell open. 



$ same as the P. , except that the middle femora have each a cluster 

 of black pile at its apex in front and two similar fringe-like clusters, one 

 on the upper, the other on the lower surface at its last third, and above 

 the middle of each middle tibia are two long dense fringes of black pile 

 on its inner and outer sides, connected with each other in front ; front 

 metatarsi destitute of appressed white pile. Length, 14 to 17 mm. Los 

 Angeles County, Cal. Four females and one male. 



Anisopogon patruelis, n. sp. £ P. . — Same as the above description of 

 rubidus, with these exceptions :-- -Head, antennae, thorax, scutellum and
