palpi were tri- to quadriarticulate. The eccentric antennal segments 
are ornamented with hyaline lamellae in addition to crenulate 
whorls, while the third vein joins costa at the apex. The rudimen- 
tary pulvilli do not extend beyond the middle of the claws. The 
lobes of the ovipositor are triarticulate. Kieffer states that this 
genus differs from Prionellus by the simple character of the claws 
and the short or rudimentary pulvilli. 
The nymph of A. miki Kieff., as illustrated by the author, is 
extremely interesting. There are the usual pair of slender, cephalic 
appendages, the smooth dorsum of the thorax is ornamented 
with two lines of stout setae arising from small tubercles, while 
the dorsum of the abdominal segments appears to be regularly 
marked with transverse rows of short, stout, chitinous points, the 
posterior margin being ornamented with a sparse row of short, 
stout, chitinous setae and the posterior angles of segments 2 to 8 
bearing long, filiform appendages, each having a length about twice 
that of the segment. The terminal segment is produced as a pair 
of stout, subconic appendages, the lateral and internal angles of 
each bearing a short, stout spine. Type Apriona bidentata 
Kieff. No American species have been recognized.

The North American members of this group are most easily 
recognized by the subapical whorls of mushroomlike append- 
ages, termed stemmed disks, on the antennal segments. Kieffer 
states that members of this genus may be distinguished by the 
minute subapical tooth of the claws, a character which in our ex- 
perience appears to be so insignificant or evanescent as to prove of 
comparatively slight service. The type of this genus is M. 
stirpium Kieff. 
The members of this group present considerable variations in the 
number of antennal segments, especially in the female, they ranging 
from 11 in M. gilletti Felt to 22 in M. articulosa Felt. 
The known males have 14 or 16 stemmed antennal segments. The 
palpi may be either tri- or quadriarticulate. The wings present the 
typical venation of Campylomyza. The pulvilli may be as long 
as the claws or rudimentary. Near the posterior extremity of the 
abdomen the females have a pair of submedian, ventral, globular 
or trumpet-shaped glands. The ovipositor is short and indistinctly
