NOTES. 



Eriphia Meigen, Syst. Beschr. v, 206, pi. 44, figs. 16-19 (1826). 

 Walker (List iv, 961-966) has referred ten species here, all from 

 Hudson's Bay Territory. He is the only author who has re- 

 ferred any North American species to this genus. I conse- 

 quently do not include it in the synopsis, as probahly not any 

 of Walker's species belonged here. Nevertheless it may be well 

 to point out its characters. It would run into Chortophila in 

 the synoptic table, providing the tegulte are small and equal 

 as I infer from Meigen's description. Meigen says only " tegulpe 

 suiall." From ChoriojjhUa it would differ only by the fact that 

 the latter genus has the anal vein reaching to the posterior mar- 

 gin of the wing. Meigen's figure of Eriphia shows the anal 

 vein not reaching the margin. The arista is very finely pubes- 

 cent, almost bare. The eyes are bare, and contiguous in the % . 

 Legs black. 



Dialyta Meig., Syst. Beschr. v, 208, pi. 44, figs. 20-2.5 (1826). 

 Walker (List, iv, 966) has referred one s[)ecies here with a 

 query. It is also from Hudson's Bay Territory. The genus is 

 not included. Meigen says the tegulse are "of moderate size." 

 The eyes are remote in both sexes, and the arista is very finely 

 pubescent, almost bare. The palpi are hardly thickened at 

 apex. Small cross-vein is opposite the end of the first longitu-
