on hind margin of second, a continuous row on hind margin 

 of third, and two rows on fourth. 



Also two females and one male, Eio Euidoso, 4 miles west 

 of Dowling's Mill, 6600 feet, July 10, on flowers of Rhus 

 (/lohra, L. (Wooton). One of the females is considerably 

 stouter than usual, and the male has the abdomen somewhat 

 different in appearance ; but it is due, I think, to the silvery 

 pollen being rubbed and obscured. 



21. Echinomyia Victoria^ sp. n. 

 Echinomyia, sp. n. ?, Towns, no. 60, Trans. Am. Ent. Soc. xxii. p. 72. 



I propose the name E. Victoria for this species, as it does 

 not seem to be named. 



Nine females, Rio Tuiarosa, below Blazer's Mill, about 

 6000 feet, Oct. 20, on flowers of Bigelovia graveolens, var. 

 qlahrata ; and a smaller female, Rio Ruidoso, above Dow- 

 ling's Mill, about 6500 feet, Oct. 15, on flowers of Senecio 

 ■Douglasii, DC. 



Front tarsi wide in both sexes ; palpi not slender filiform, 

 but thickened and much shorter ; sides of face without the 

 pair of bristles near orbits ; second antennal joint reddish 

 yellow ; proboscis shorter and stouter. Otherwise this 

 species agrees with E. iterans, except that thorax is less 

 brassy, and the abdomen has median line of black spots 

 usually well pronounced, sometimes widened beliind on last 

 two segments. The species is on the average more robust. 

 It diff'ers chiefly from E. dakotensis, Towns., by the prevailing 

 reddish-yellow colour of abdomen, dakotensis having much 

 more black on abdominal segments. 



Also one male, Rio Ruidoso, 8500 feet, July 6 {Wooton). 



22. Echinomyia neglecta, sp. n. 

 Echinomyia, sp. aff. Thoymoni, Will., and iterans, "Walk., of Towns. 



This species I have known for some time, and as it seems 

 to be also without a name, I propose to call it E. neghcta. 



Three females, Rio Tuiarosa, below Blazer's Mill, about 

 6000 feet, Oct. 20, on flowers of Bigelovia graveolens, var. 

 glahrata. Three females, Rio Ruidoso, above Dowling's 

 Mill, about 6500 feet, Oct. 15, on flowers of Senecio 

 Douglasii, DC. 



This species diff'ers from Thomsoni by the antennae being 

 wholly deep black instead of second joint reddish yellow ; in 

 abdomen (except imperfect median stripe) being brighter red,
