Dec, I9IS-] Townsend: New Muscoidea. 217 



fleshy, less than head-height, part below geniculation hardly as long 

 as antennae. Palpi well developed, hardly as long as third antennal 

 joint, faintly thickened at tip. Antennae inserted but little below 

 upper eye limits, reaching well short of vibrissse; second joint dis- 

 tinctly elongate, rather longer than the distance between vibrissje and 

 oral margin; third joint hardly twice as long as second, equilateral, 

 about same width as tip of second, evenly rounded at tip. Arista 

 porrect, strong, thickened, tapered to sharp point, basal joints very 

 short. Eyes practically bare, hardly twice as long as greatest width, 

 descending about even with tips of antennae. Front at vertex taking 

 up fully half of head-width, slightly widening anteriorly. Para- 

 frontals broad anteriorly, narrowing rapidly posteriorly, with a very 

 few scattered minute bristly hairs. Frontals descending about to tip 

 of second antennal joint, two placed below base of antenn.ne, three 

 decussate pairs above base. Verticals both well developed. Three 

 proclinate fronto-orbitals, of which the middle one is weak and the 

 other two strong; three strong reclinate ones in line with frontals, 

 and one or two very weak bristles in line with and immediately be- 

 hind the proclinate. Frontalia anteriorly as wide as antennal base, 

 widening posteriorly to about twice the anterior width but not occu- 

 pying quite one half the vertical width of front. Ocellars present, 

 strong, divaricate. Parafacials above broader than clypeus, dis- 

 tinctly narrowed below, broadening again slightly at cheek grooves, 

 their planes converging anteriorly at an angle of about 45 degrees; 

 two or three downwardly-directed macrochsetae near front edge, about 

 level with middle of third antennal joint. Cheeks a little less than 

 one half eye-height, rather longer than broad. Cheek-grooves very 

 faintly marked, hardly impressed but extensive, ascending broadly 

 behind lower half of eye. No geno-orbitals. Sternopleurals, 0:2:1; 

 postsuturals, 3 ; preacrostichals, 3, rather weak ; postacrostichals, 3, 

 but front one or two weak. Three strong lateral scutellars ; weak 

 closely-approximated apical pair slightly removed from edge ; about 

 four weak discals in irregular row. Wings about as long as abdomen, 

 nearly two and one half times as long as broad. Costal spine short 

 and stout, distinctly longer than costal bristles. Third vein bristled 

 about to small crossvein, its course very straight beyond same. Apical 

 cell rather narrowed, open, terminating nearly as far before wing-tip 

 as length of apical crossvein. Fourth vein represented by wrinkle
