Subgenus MELINA Desvoidy 



In this group are placed those species having the wings hyaUne 

 or, at most, marked or clouded along the veins or costa. They 

 have well developed propleural and two frontal bristles. 



Melina fusca new species 



This species may be recognized by the general ferruginous 

 color, instead of black as in the other associates, and by the 

 mesopleura being setulose along the posterior margin. The type 

 seems to agree with a specimen seen in the United States National 

 Aluseum under the name Sciomyza dorsata, but which does not 

 agree with Hendel's description of that species. 



9 . Brown to j-ellowish brown. Mesonotum, metanotum, bases of ab- 

 dominal segments, upper surfaces of femora, darker; an interrupted median 

 abdominal stripe also darker. Wings In-aline with cross-veins clouded. 

 Opaque, ochreous dusted; mesonotum with four stripes. Scutellum paler. 



Frons broad as long; the opaque graj' frontal stripes not more than one- 

 half of length of frons. Arista short plumose. Cheeks not one-half of eye- 

 height. Mesopleura setulose along posterior margin, otherwise bare; ptero- 

 pleura setulose and with two bristles; fore coxae with three bristles; small 

 cross-vein slightly beyond middle of discal cell. Length. — 5 mm. 



Type.— 9, University, North Dakota, June, 1896, (R. P. 

 Currie), [U. S. N. M.]. 



The specimen was found in the National Museum under the 

 name S. obtusa Fallen. It seems to be obtusa according to Loew 

 (1862), but not Hendel (1902). 



Melina vitalis new species 



In color and structure similar to nana Fallen, but the wings, 

 with the exception of the cross- veins are hyaline, without any 

 trace of infuscation or color excepting the yellow stigma. It 

 should not be confused with pubera or similis. 



d'. Black, grayish dusted. Frons, face, cheeks, lower occiput, fore coxae, 

 middle and hind legs, and halteres, pale. Fore legs excepting knees, entirely 

 black; middle and hind femora and tibiae, at most, with faint apical infus- 

 cation. Wings hyaline, stigma yellow^; cross-veins at most very narrowly 

 clouded. Mesonotum finely irrorated, at most, faintly vittate; scutellum 

 concolorous. Abdominal bands entire; apices of segments narrowly white. 



Frons broad as long, with two frontals; anterior portion sUghtly shining. 

 Ai-ista bare or micro-pubescent. Mesopleura entirely bare; pteropleura 

 setulose and with two bristles. Fore coxae \\-ith two bristles beneath. Small 

 cross-vein beyond middle of discal cell. Length. — 3 to 5 mm.
