8. Sapromyza vulgaris. 



Chlorops vulgaris, Fitch, Reports, vol. i., 300, pi. i., 



fig. 4. 

 Sapriiviyza plumafa, Van der Wulp, Tijdsclu'., v., 



Eutom. (2), 159. — Atlantic States. 



Sapromyza oceUans, Townsend, Can. Entom., 1893, 



303; F. Lynch, A., An. Soc. Cient. Arg., xsxiv., 



283, 1893.— New Mexico. 



(^ , $ . Front reddish-yellow, broad, a minute spot at the 



ocelli ; ocelli with two well-developed ocellar bristles. Antennse 



yellow, the third joint black at the lip, and along the under side, 



more than twice as long as wide ; arista plumose on the upper side. 



Face and cheeks light-yellow. Thorax shining ; me^notum 



reddish-yellow, the pleurce more yellowish. Scutellum large, with 



four bristles on its margin. Abdomen yellow, brownish-yellow or 



brown ; in some specimens reddish-yellow with a narrow, but 



distinct, brown band on the posterior part of each segment. Legs 



smoky hyaline ; penultimate section of the fourth vein not more 



than one-half the length of the ultimate section. Palpi black at 



tip. Length 4-5 mm. 



Numerous specimens. St. Vincent. 8. cincta, Loew, 

 from Cuba and Porto Rico (Roeder), must be very 

 closely allied, probably identical with this species. 



9. Sapromyza venusta, n. sp. 



(^ , $ . Front rather narrow, nearly twice as long as wide, 

 opaque brownish-yellow, with three pairs of recurved bristles. 

 First two joints of the antennae yellow ; third joint black, oval, 

 about twice as long ae wide ; arista black, short pubescent. Face 

 and cheeks light-yellow ; palpi for the most part black. Thorax 

 shining yellow, with three broad, brown or brownish stripes, the 

 middle one obsoletely geminate. Abdomen brown, at the base 

 yellow. Legs yellow. Wings smoky hyaline ; penultimate section 

 of the fourth vein but little more than one-third of the length of 

 the ultimate section. Length 4 mm. 



Six specimens. In some of the specimens, the abdo- 

 men has a median series of black spots, with the sides 

 of the segments blackish. Like most specimens in this 

 genus the abdomen has seemed to suffer in its coloration 

 in drying, and fresh specimens are needed to determine 

 the markings with clearness.
