NO. 2128. NEW GENERA OF MUSCOID FLIES— TOWNSEND. 627 



front. Eyes thinly and faintly short-hairy. Frontal bristles reach- 

 ing about to end of second antennal joint. Abdomen of female 

 shghtly broader than the thorax, suboval. Apical cell narrowly 

 open a Httle before wingtip. Male unknown. 



PYRAUSTOMYIA, new genus. 



Genotype. — Panzeria genitalis Coquillett, Rev. Tach., 1897, p. 89. 



Differs from Phijllomya as follows: Male.—Ejes hairy. No 

 procUnate fronto-orbitals. Parafacials practically bare. Arista bare. 

 Head about as long at oral margin as at antennae, epistoma weU 

 produced. Palpi stout, well thickened apically. Front about 

 three-fifths eye-width on posterior half. Second antennal joint 

 elongate. Whole body much broader, thorax and abdomen equaUng 

 head-width. Posterior one of the two lateral scutellar macrochaetae 

 not much longer than the anterior one. First abdominal segment 

 not so elongate, without macrochaetae other than laterals. Second 

 segment without marginal row; but with median marginal, discal, 

 and subdiscal paii-s. Third segment with median discal and sub- 

 cUscal pairs, of which one is often weaker, and marginal row. Costal 

 spine present. i\.pical crossvein not bent in. 



The holotype of the above species was reared by Dr. C. V. Riley 

 from Pijrausta penitalis at St. Louis, Missomi, June 1, 1876. 



XANTHOPHYTO, new genus. 



Genotype.— Nemoraea laUs Coquillett, Journ. N. Y. Ent. Soc, vol. 3, 



1895, p. 104. 



Differs from Phyto as follows: 



Female.— FrowidX bristles doubled or trebled anteriorly, descendmg 

 to base of third antennal joint. Frontalia narrowing posteriorly. 

 Eyes haky. The single pan- of inner fronto-orbitals divaricate. 

 Antemiae inserted very high, above upper tliree-fourths of eye, the 

 frontal length only a httle greater than facial. Parafacials bare. 

 Palpi strong, thickened apically. Antennae stouter, the third joint 

 longer and subtmnoate apically. Macrochaetae of head stronger. 

 Face a Httle broader. Abdomen broader. Apical cell widely open a 

 Httle before wmgtip, fourth vein continued in strong stump, apical 

 and hind crossvems both nearly paraUel with hind margin of wmg. 

 Tegulae broader and larger. 



Family LARVAEVORIDAE. 

 LESKIOPSIS, neAAT genus. 



Genotype.— MyioJna thecata CoquiUett, Journ. N. Y. Ent. Soc, 

 vol. 3, 1895, p. 105; Rev. Tach., 1897, p. 67, refeiTed to Leslcia. 



Differs from Leslcia as foUows: Front of male much narrower and 

 sUghtly narrowmg anteriorly or equilateral. Head subhemispherical,
