brown; fore tarsi scarcely one and a half times as long as their 

 tibiae. Wings as in the male. 



Described from one pair which I took at San Francisco, Cali- 

 fornia, May 12, 1915. Type in the author's collection. 



Paraclius minutus sp. nov. 



Male: Length 2.5 mm.; of wing 2 mm. Face rather narrow, 

 covered with white pollen, the snture near apical third, lower por- 

 tion flat. Palpi blackish with a little wliite pollen and black hairs. 

 Front almost opaque with brown pollen. First two antennal joints 

 yellow; third mostly brown, small, rounded at tip. Arista long 

 with long pubescence, but scarcely plumose. Inferior orbital cilia 

 whitish. 



Thorax greenish, dorsum more brown with coppery reflections, 

 which form a median vitta extending to the hind margin of the 

 scutellum. The ante-alar black spots distinct but nearly divided 

 by the green of the dorsum; Avhen viewed from behind there are 

 four silvery-white spots visible, a large one at the lower edge of 

 the front end of the black spot, and a very small one above the 

 root of the wing; pleaurse and coxae covered with white pollen. 

 Abdomen green; the spots of white pollen on its sides not very 

 conspicuous, Hypopygiuni rather small, entirely sessel, black; its 

 lamellae quite small, black, they appear to be nearly bare on their 

 edges. 



Coxae yellow, middle ones blackened on basal half, hind ones a 

 little blackened at base; anterior pair with black hairs on their 

 front surface. Femora and tibiae yellow. All tarsi black from 

 the tip of the first joint. Calypters and halteres yellow, the former 

 with black cilia. 



Wings tinged with brownish gray; first section of costa not 

 thickened, last section of fourth vein rather abruptly bent beyond 

 its middle, beyond which it curves forward so the tip is near the 

 tip of the third vein ; last section of fifth vein a little longer than 

 the cross-vein. 



Female: About like the male in the width of the face, color 

 and venation, except that the last section of the fifth vein is a 

 little longer. 



Described from two males and three females which I took in
