and tarsi brown, the apical segments of the latter darker. 

 Wings subhyaline, the veins suffused with pale brown, 

 darkest at the stigma where it occurs as a semicircular mark ; 

 a dark cloud beyond Rs in cells Sc and ist i?i ; veins dark 

 brown, C and Sc more yellowish. Venation : Sc ending just 

 before the fork of the short, slightly convex sector, Sc^ at 

 the tip of Sc-i^ ; Rs about twice the deflection of R^^r, ; R-^ with 

 a long spur beyond r and the tip of R-^ ; r-m a little shorter 

 than the basal deflection of i?4+5 ; veins i?2+3 and i?4+g de- 

 flected strongly caudad at about two thirds their length and 

 running generally parallel to one another ; basal deflection of 

 C% near midlength of the rectangular cell ist M^- In the 

 female the only distinct marking on the wing is the con- 

 spicuous, rounded, brown stigma; the spur at the end of R,^ 

 is shorter and m is more arcuated. 



Abdominal tergites obscure brownish, the basal sternites 

 bright yellow. In the female the tergites are dark brown, 

 possibly discolored. Ovipositor with the valves rather short, 

 the tergal valves slightly upcurved. 

 Habitat. — Samoa. 



Holotype, J*, Apia, June, July, 1913 (R. W. Doane) ; Allotopo- 

 type, ?. 



It now seems very probable that the fly described as Teucholabis 

 fijiensis Alexander (Ann. Ent. Soc. America, Vol. 7, p. 240; 

 1914) is not a true Teucholabis and is possibly more nearly re- 

 lated to Libnotes. 



Rhipidia tusitala sp. n. 



General coloration pale yellow ; head grey ; antennal seg- 

 ments produced into flattened disks whose margins are pro- 

 vided with stout spinous bristles ; wings pale yellow, veins 

 C and R incrassated ; Sc short, cell i?i very large and oval due 

 to the strong bending of vein Ro+s toward i^^+g near its base. 



Male. — Length about 5.6 mm. ; wing, 7.5 mm. 



Rostrum and palpi dark brown. Antennae pale brownish 

 yellow, 14-segmented, the basal segment elongate-cylindrical ; 

 ultimate segment formed by the evident fusion of two smaller 

 segments ; intermediate flagellar segments with the inner face 

 strongly produced into a serration ; around the periphery of 

 these disk-like segments are a series of about six stout, 

 spinous bristles of which three are grouped near the tip of 

 the serration; surface of the flagellar segments microscopic- 

 ally alutaceous. Head light gray. 



Mesonotum light yellow, the postnotum more whitish. 

 Pleura pale whitish yellow. Haiteres pale. Legs pale yel-
