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. Kiefler states that this 

 genus differs from Prionellus by the simple character of the claws 

 and the short or rudimentary pulvilli. 



The nymph of A . m i k i 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 . 

 s t i r p i u m 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
