cent, longer tlian in tlie tliorax, especiallj^ on the sides of the anterior seg- 

 ments, the dorsum in the middle nearly bare. Legs black with black and 

 lutescent pile, tibife reddish at base and extreme tips. Teguhe light yel- 

 low, halteres yellow. "Wings smoky brown, darker in front and at the 

 root. One specimen. California. Long. corp. 11 mm. 



An additional species from California has larger, more reddish subquad- 

 rate third joint of antenna^ arista siiort pilose, no pile that I can dis- 

 tinguish in the face, and the pile of the body shorter. 



Cheilosia lasiophthalmus, sp. nov. 



(^. — Frontal triangle moderatelj'- swollen, with an impressed longitudi- 

 nal line, and light yellowish pile. Antennae brownish red, thii'd joint 

 rather large, nearly square, arista bare, black. Face deep black, shining 

 with yellowish pubescence, slightly excavated below the antennae, con- 

 siderably produced below the eyes, a well-marked groove begins at the 

 base of the antennfe, runs obliquely outward to the eye, and then curves 

 downward near the eye into the cheek. Posterior orbits below broadly 

 dusted with yellow. Eyes thickly reddish-yellow pilose. Thorax metal- 

 lic green, shining, thickly covei'ed with light yellow pile, on the pleursB 

 ])ushy. Abdomen broad oval, shining black, with abundant pile like that 

 of the thorax. Teguhe light yellow. Legs black with yellow pile, femora 

 at the tips, base and tips of tibiae, and basal joints of intermediate tarsi, 

 yellow or luteous. Wings subhyaline, Avith an indistinct brownish spot 

 near the middle, basal part yellowish. Long. corp. 10-llmm. Four speci- 

 mens. Colorado. 



Female specimens that may belong to this species from California have 

 the pile much shorter and more grayish. They are too badly preserved, 

 however, for me to determine with any degree of assurance. 



Cheilosta rufipes, sp. nov. 



9. — Front and f\xce shining black, theforaier on the sides and the latter 

 except the tubercle lightly covered with minute gray pubescence. An- 

 tenna? blackish, third joint twice 'as long as wide, reddish on the under 

 side, arista bare. Thorax metallic green, lightly punctulate, pile very 

 short, whitish ; scutellum with an indistinct, transverse groove. Abdo- 

 men black, with a metallic reflection, smooth, shining, elongate oval, with 

 a small tuft of whitish pile on the side of the second segment, and very 

 short, elsewhere ; second segment with large oval spots in front, narrowl^^ 

 separated ; third segment with broad cross-bands in front, attenuated in 

 the middle ; the fourth segment with similar but less attenuated ; the fifth 

 segment partly or wholly, bluish green. Legs red, posterior femora an- 

 nulate near the middle, or almost Avholly brown or blackish, terminal 

 joints of tarsi infuscated. Wings hj^aline, stigma dilutcly j'ellow. Long, 

 corp. 8-9 mm. Washington Territorj^ California. Five specimens. 



The abdomen is not sufficiently fasciated to place it among the Melano»- 

 lornce ; in everything else it presents the characters of Cheilosia.
