Sternum glabrous, ovoid, pointed caudad; setz diverse, few, distributed 
over the sclerites; conjunctiva smooth, hyaline. 
Segment IX. Suranal plate glabrous, scoop-shaped; sete approx- 
imate, less than the width of the club apart, long, exceeding by twice 
the length of the plate, few setulae; subanal plate spinulose, spade- 
shaped; marginals long, setulae sparsely distributed; cerci sparsely 
spinulose, conical to subcylindrical, petiolate, setee consist of three long 
apicals and numerous bristlelike setule distributed on the petiole and 
club; sense organs, tubercular, situated laterad. 
Chortophila fugax Meigen, and substriata Stein.* 
Segments longer than the intersegments, breadth exceeds length. 
Intersegments spinulose. 
Segment VI. Tergum glabrous, completely chitinized, encasing the 
whole region, ventral margins protruding; marginals few, diverse, 
unevenly distributed, continuing along the ventral margin; accessory 
pieces absent; spiracles the width of the sternum apart, oblique, pos- 
terior spiracle considerably dorsad of the anterior one, in the region of 
the caudal margin of segment. Sternum spinulose, spatulate, extending 
the length of the segment; marginals in two separate groups along the 
lateral margins; conjunctiva spinulose. 
Segment VII. Tergum glabrous, completely chitinized as in seg- 
ment VI; discal area vestigial; marginals diverse, distributed irreg- 
ularly around the caudal margin; accessory pieces absent. Sternum 
spinulose, spatulate, thinly chitinized cephalad, marginals wide apart, 
grouped laterad; conjunctiva spinulose, striated. 
Segment VIIL. Tergum, caudal half spinulose, cephalic half glabrous, 
completely chitinized across the tergal region; marginals equal, irreg- 
ularly distributed. Sternum spinulose, elongate; sete sparsely dis- 
tributed over the surface; conjunctiva spinulose. 
Segment IX. Suranal plate spinulose, scoop-shaped, setz very long, 
21% times the length of plate; setulae few; subanal plate, broad, spade- 
shaped, spinulose; marginals short, setulae equal, numerous; cerci 
spinulose, setulae short; sense organs, two contiguous, one separate. 
Chortophila grisella Rondani.* 
Segments and intersegments of equal length, sclerites glabrous 
except the subanal plate which is spinulose. Intersegments smooth, 
without vestiture, in common with the segmental membranes orna- 
mented with chitinous granulations. 
Segment VI. Tergum somewhat similar in structure to antiqua, the 
lateral plates expand along the caudal and cephalic margins almost 
fusing across the mid-dorsal line; discal area semi-opaque, coarsely 
granulated; marginals short, equal, regular, terminating on either side 
in a strong sete; spiracles the breadth of the sternum apart, oblique, 
the anterior spiracles dorsad of the posterior, the latter twice the size of 
the former and situated at the bases of the strong marginal sete; acces- 
sory pieces absent. Sternum reduced to a small cordate sclerite adjacent
