NORTH AMERICAN DIPTERA.

Described from two specimens ; a % from Prof. J. M. Aldrich, 
Brookings, South Dakota, and a 9 from Prof O. Lugger, Minn. (?) 
have })referred to locate this species in the genus Apliria, although 
in some features it closely approaches OUvierla, but differs from it 
also in others very essentially. The jiroboscis is long, but bardly 
bristle-like and not horizontally protruded. It is straight and per- 
pendicularly extended, of about the same size and length as in 
Ocyptera, but, unlike that genus, possesses well-formed palpi. The 
eyes are extremely thinly pubescent and the apical cell closed in the 
margin, both of which characters lead to Aphria in Schiner’s table, 
but are denied it in his generic characterization. From Olivi.eria it 
differs in the receding (not almost perpendicular) face, in the longer 
and more slender proboscis, and in the absence of discal macrochpetic 
on the abdominal segments. 
Nemonea 7nasnrius Wlk., N. clasides Wlk., and N. trixoicles Wlk. 
Mr. van der \Yulp has called attention to the fact (Biol. C.-A. Dipt, 
ii, 47) that none of these three species belong in the genus Nemnnv.a, 
since the eyes in all of them are bare. 
Kxorisfa. ciliata n. sp. . — Head ratber small, not as wide as thorax, 
abdomen wider. Eyes reddish brown, thickly pubescent; front at vertex and 
middle hardly more than one-seventh the width of head, widening a little before, 
face much wider; frontal bristles in a single row, descending nearly to base of 
third antennal joint, front thickly fine had ry outside the rows of bristles; the 
pair of bristles at vertical angle very short, the inner one longer; no bristles in 
frontal row for nearly one-half way from vertical border of occiput to base of 
antennae, only fine black hair; rest of space occupied by frontal row, the bristles 
directed inward, decussate, except below antennae; occipital area finely black 
hairy, with two pairs of short bristles, the forward pair a little longer; no or- 
bital bristles; vertex blackish, sides of front cinereous; frontal vitta blackish, 
velvety, moderately narrow, split behind on each side of ocelli; sides of face 
narrow, silvery-cinereous, rather thickly black hairy; facial depession silvery- 
cinereous, rather wide below, facial ridges bare, except a very few bristles just 
above vibrissm, the latter decussate and inserted well above the oral margin ; 
cheeks replaced under eyes by the cinereous, black hairy occipital area, also hairy 
in front, with bristles on lower and front borders; antennse much shorter than 
face, blackish, third joint more brownish; first joint very short, second slightly 
elongate, bristly ; third once and a half as long as second, but slightly widened ; 
arista long, brown, slightly thickened about half its length, microscopically 
short pubescent, distinctly 3-jointed, second joint not elongate; proboscis ap- 
parently but half as long as hight of head, blackish, labella much developed ; 
palpi flavous, dark at base, somewhat club-shaped, black bristly; occiput cine- 
reous, densely gray hairy, with fringe of black bristles on orbital margins. 
Thorax, widened, bluish black, slightly cinereous, hairy, bristly, with four cpiite
