This handsome species is readily told from related species 

 of the subgenus by its handsomely banded wings, in this re-

Tribe Limnophilini 

 Phyllolabis flavida sp. n. 



Coloration pale yellow; wings nearly hyaline, stigma lacking; vein 

 Sc long, R2+3 arcuated, about equal to cell R* alone ; inner end of 

 cell ist M:>, slightly proximad of r-m.

Rostrum and palpi pale yellow. Antennae elongate, in the male, if 

 bent backward, extending about to the base of the abdomen, the 

 flagellar segments cylindrical, with moderately long hairs ; antennae 

 pale yellowish, the terminal segments darker. Head brownish-yellow; 

 eyes large, black. 



Thorax pale brownish-yellow, without distinct stripes. Halteres 

 elongate, pale, the knobs brownish. Legs pale yellowish, the tarsi 

 dark brown. 



Wings rather broad, pale, subhyaline, stigma lacking; veins brown. 

 Venation: Sc long, ending just before the middle of /?_=>+.?, in the 

 other described species of the genus Sc is much shorter, ending just 

 beyond the fork of the sector ; R2-\-$ arcuated, shorter than, or sub- 

 equal to R2 alone; inner end of cell ist M* slightly proximad of r-m. 



Abdomen pale yellowish, the segments ringed caudally with darker. 

 Segments eight and nine, and the posterior half of seven, black; hypo- 

 pygium orange-brown. Male hypopygium with the caudal projection 

 of the eighth sternite long, slender, narrow at the base, gradually and 

 slightly expanded toward the apex, which is bilobed and pubescent; 

 just dorsad of this blade are two needle-like blades. Lateral pro- 

 longations of the pleurites elongate, curved, fringed at the tips and 

 along the sides with long stout hairs, the apical portion of this arm 

 expanded. Ventral inner pleural appendage sickle-shaped, with a 

 slender handle, the blade widely expanded, curved outwardly, the 

 acute lips directed inwardly; dorsal inner pleural appendages bifid, the 

 inner arm longest and decussate with its fellow of the opposite side.

Related to /'. cluriijcr C). S. in the lack of a stigmal spot 

 to the wings, but very distinct in its pale coloration, vena- 

 tional details, and, especially, the peculiar male genitalia.
