Runs to Masicera myoidcea in Coquillett's Rev. Tach. Differs 

 from Paraphorocera radicis T. (subgenus B) as follows: 

 Female. Front at vertex less than one-fourth of head-width, 

 face below about one-half same. Outer vertical vestigial, not 

 at all developed. Antennae slightly more slender, relative 

 length of joints same ; second aristal joint not elongate. Cheeks 

 a little narrower, parafacials narrower and more rapidly nar- 

 rowed below; eyes with faint hairs that are a little more 

 easily distinguished. Front not so produced in profile ; f ron- 

 talia averaging as wide as one parafrontal. Practically the 

 identical chaetotaxy of thorax, scutellum, and abdomen ; second 

 segment without discals, the discals of third segment rather 

 weak, anal segment with a scattering of short erect micro- 

 chaetse. Abdomen deep, tip rather rounded. Apical cell ends 

 a little nearer wing-tip, and the cubitus is well approximated 

 to margin. Two to three bristles on base of third vein.

 tribution of pollen, agrees perfectly except only that the 

 tegulae are more nearly white.
