 Sapromyza jplumata^ Yan der Wulp, Tijdsclir,, v., 



Entom. (2), 159. — Atlantic States. 

 Sajpromyza ocellaris, Townsend, Can. Entom., 1893, 



303 j F. Lynch, A., An. Soc. Cient. Arg., xxxiv., 



283, 1893.— New Mexico. 



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

 ocelli ; ocelli with two well-developed ©cellar bristles. Antennae 

 yellow, the third joint black at the tip, 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 ; mesonotum 

 reddish-yellow, the pleurae 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. Yincent. S, 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 as 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 sufier in its coloration 

 in drying, and fresh specimens are needed to determine 

 the markings with clearness.
