DESCRIPTION OF OVIPOSITORS. 
An asterisk qualifying the name of a species signifies that the specimen 
keys out to that species in Stein’s key (1914) to the females of European 
Anthomyide. 
Genus Chortophila MAcQuart. 
Chortophila antiqua Meigen. 
Segments and intersegments of equal length, sclerites glabrous, 
except the subanal plate which is spinulose. Intersegments one, two, 
and three spinulose, fourth smooth. 
Segment VI. Tergum in structure and character similar to célicrura, 
usually more heavily chitinized, the discal area appearing yellowish; 
accessory pieces present; marginals diverse, in an irregular row; spir- 
acles approximate, barely the width of the sternum apart, in the same 
straight linet, posterior spiracles cephalad of the accessory pieces. 
Sternum somewhat pegshaped, the cephalic half narrowed to a blunt 
point which attains the cephalic margin; sete grouped apart around 
the caudal margin; conjunctiva smooth, with chitinous thickenings. 
Segment VII. The tergum similar to that of segment VI, the 
tergites less chitinized; accessory pieces present. Sternum lanceolate, 
tapering to a blunt point on the cephalic margin, flaring caudad; mar- 
ginals distributed in a broad semicircle along the caudal border; 
conjunctiva as in segment VI. 
Segment VIII. Tergum divided bilaterally, the tergites strongly 
chitinized along the caudal margin of the segment as in cilicrura; the 
sclerites proceed dorsocephalad as undulating plates, scarcely attaining 
the cephalic margin; marginals diverse, more numerous than in cili- 
crura, regulart. Sternum composed of two ovoid sclerites, but one-half 
the length of the segment; setze diverse, scattered caudad; conjunctiva 
smooth, studded with chitinous knobs. 
Segment IX. Suranal plate scoop-shaped; setz less than the width 
of the club apart; subanal plate spinulose, spade-shaped to triangular; 
setae long, fine, hairlike, bounding the apical third of the sclerite, setulz 
diverse; cerci glabrous, club compact, petiole short; setze composed of 
one long apical and three or four shorter, besides long spinelike setule. 
Chortophila brassicz Bouché. 
Segments and intersegments of equal length, sclerites glabrous 
except the subanal plate which is spinulose. Intersegments spinulose 
except for the fourth whose ventral surface is smooth. 
Segment VI. Tergum divided bilaterally, the tergites border the 
caudal and cephalic margins, in the former case the sclerites tend to 
fuse across the mid dorsal line, ventral and dorsal margins indeter- 
minate; discal area slightly chitinized blending imperceptibly with the 
+ As opposed to oblique. 
t Regular=In a single row.
