of priority compels us to adopt the oldest name. Our species have 
three postsutural and three sternopleural macrochietie; front tarsi of 
female as broad as the apex of the front tibix, in the male much 
narrower: 
Cheeks bearing black macrochietie in the centers, frontal vitta black 
or dark brown, male destitute of orbital bristles, his genitalia at 
most projecting one-fifth the length of the fourth abdominal seg- 
ment beyond the latter, hind crossvein bent nearly S-shape; 
length, 11 mm. White Mountains, New Hampshire; Beverly, 
Mass., and Austria. Two males and one female from Austria 
received from Brauer and Bergenstamm and by them named 
Micropalpus hemorrhoidalis Fall. and Micropalpus pudicus Rond., 
but both names are evidently wrong, since the male of hamor- 
rhoidalis is provided with orbital bristles, and pudicus has no 
black macrochietie on the center of the cheeks. (System. Besch.

Cheeks destitute of black macrochete near the centers, frontal vitta 
light yellow, male provided with two pairs of orbital bristles, his 
genitalia projecting nearly half the length of the fourth abdom-

Our single species is black, the antenne, palpi, and fourth abdominal 
segment except its extreme apex, yellow; three postsutural and three 
'Meigen did not recognize comta, and therefore unknowingly redescribed it under 
the name of fulgens; this was suspected by Zetterstedt (Dipt. Scand., Vol. ILI, p. 1097; 
1844) and given as certain by Rondani (Dipt. Ital. Prod., Vol. III, p. 70; 1859). The 
comtus of Schiner, Fauna Austriaca, Vol. I, p. 429, is not that species, but a color variety 
of hamorrhoidalis; the species he describes under fulgens is the true comtus. In the 
Annales Soc. Ent. France for 1844, page 31, Desvoidy acknowledges that his Linnw- 
mya heraclvi, analis, and wstivalis belong to one species, and in the same serial for 
1845, page 271, Macquart adds borealis to this list and refers them to fulgens. The 
name of Micropalpus piceus was proposed by Macquart to take the place of Marshamia 
analis Desvoidy. The writer is responsible for the synonymy of piceus, distincta and. 
nigripes.
