antero-ventral, each slightly below the corresponding antero-dorsal, 

 and one weak postero-dorsal bristle on middle; pulvulli white, long; 

 claws long. Wings grayish; costal thorn distinct, but not large; 

 penultimate section of fourth vein distinctly over one-half as long as 

 last section; outer cross vein slightly waved. Calyptrse black- 

 brown. Halteres yellow. 



Length, 4-5 mm' 



Type.— C&t. No. 15671, U.S.N.M. 



Type-locality. — Franconia, New Hampshire (Mrs. A. T. Slosson). 



Paratypes. — Ottawa, Canada; Montreal, Canada; St. John, New 

 Brunswick, June 25, 1901 (W. Mcintosh); White Mountains, New 

 HampsMre (Morrison). This species comes close to some of those 

 which have been placed in LimnopJiora, but the much more widely 

 separated eyes should readily separate it from any species in that 

 genus. 



ANTHOMYIA BIDENTATA, new species. 



Male. — Deep black, subopaque. Frontal triangle reddish-brown; 

 face black, white pollinose, cheeks brown, silvery pollinose. Mesono- 

 tum without stripes or spots, lateral margins slightly gray pollinose. 

 Abdomen deep black, with only two small grayish-white, dentate, 

 post-marginal marks on each segment. LegSv entirely black. Ca- 

 lyptrae wliite. Halteres yellow. Wings clear. 



Head rather large; frons in profile barely projecting; eyes very 

 large, almost twice as high as long, leaving a rather narrow cheek; 

 frontal triangle rather broad in front, almost triangular, the eyes 

 widely separated to near ocelli where, shortly in front of that part, 

 the frontal stripe becomes linear; orbital bristles numerous, but not 

 strong; antennae distinctly shorter than face; second joint with one 

 long and several short bristles; third joint about 2^ times as long as 

 second; arista rather short, barely 1^ times as long as third antennal 

 joint, swollen at base, slightly pubescent; vibrissa slightly differ- 

 entiated from the numerous, and moderately strong, marginal 

 bristles; palpi rather above normal size, slightly spatulate, bristles 

 numerous, but not strong, proboscis thick. Mesonotum with acros- 

 tichal bristles 2-rowed, three pairs anterior to the suture; the tuft of 

 hairs above fore coxae strong and dense. Abdomen short, not as long 

 as thorax, broad, subovate; whole surface covered with rather long, 

 setulose hairs. Fore tibia with a weak bristle on the postero-dorsal 

 surface near middle and one on dorsal surface near to apex; mid 

 femur with a row of hairs on postero-ventral surface, which are at 

 base longer than the diameter of the femur and end at about middle 

 much shorter than they are at base; mid tibia with one dorsal bristle 

 slightly above the apical third, and two on postero-dorsal surface, 

 one below the level of the dorsal one, and the other at about middle, 

 all three bristles weak; hind femur, antero-ventral side, with a
