42o THE NORTH AMERICAN EMPID.E—COQUILLETT. vol.xviii. 



RHAMPHOMYIA SETOSA, new species. 



Male.—Hend black, gray polliuose, eyes coutiguous, upper facets 

 miicli larger tliaa the lower ones; aiitenuai black, tliird joint rather 

 broad at base, style one-third as long as the third joint; proboscis 

 slightly longer than height of head, pali)i black. Thorax black, sub- 

 shining, its pile long and rather abundant, black; pleura black, gray 

 pollinose, its pile black; scutellum black, gray polliuose, bearing eight 

 bristles. Abdomen black, subshiuing lightly grayish-black pollinose; 

 its pile long and rather abundant, black; hypopygium rather large, 

 ui)i)er lamella' short, as broad as long, each bearing at its upper angle 

 a backwardly directed hook; middle lamelljTe much longer than the 

 upi)er, long black pilose on lower side, and just before the tip bearing 

 a rather long, downwardly directed process; filament very thick at 

 base, then suddenly attenuated and arcuate, the attenuated portion 

 rather robust. Legs black, simple, rather stout, furnished with many 

 long black pile; front and middle metatarsi nearly equally slender, the 

 hind ones slightly thicker than the others. Knob of halteres black. 

 Wings hyaline, tinged with brown in the basal and anal cells; stigma 

 grayish biown, veins dark brown, entire, costa near the base bearing- 

 two long black bristles. 



Closely related to R.nifirican.s, Loew, but in that species the filament 

 of the hypopj^gium is fiexuous toward the apex and not suddenly thick- 

 ened at the base, the wings are whitish and without the brown tinge in 

 the basal and anal cells, the base of the costa bears a single long- 

 bristle, and the abdomen is Avhitish pollinose. 



It is also closely related to 7^. elanif/era, Loew, which I have not seen, 

 but in that species the upi)er lamellic of the hypopygium are described 

 as being slender, instead of very broad, and the filament is said to be 

 very slender, instead of rather robust, and suddenly thickened at the 

 base. 



Type. — No. 3211, U.S.ISr.M.; length, :>.} mm. Four males in the 

 Museum collection. 



Locality. — New Hampshire. 



RAMPHOMYIA INSECTA, new species. 



Male. — Black, including the palpi and halteres, the abdomen and legs 

 tinged with brown ; eyes contiguous, upper facets noticeably larger than 

 the h)wer ones; third antennal joint rather broad, the style one-third 

 as long as this joint; proboscis subequal in length to height of head. 

 Thorax and pleura opaque grayish-brown i)ollinose, the pile of the 

 former rather abundant and long, black on both thorax and pleura. 

 Scutellum bearing four bristles, besides a few short pile. Abdomen 

 depressed, subshiuing, its jnle rather abundant, that on the dorsum very 

 short, mixed yellowish and black; hypopygium rather large, somewhat
