Teucholabis anthracina sp. n. 



General coloration shiny coal-black; wings subhyaline with a 

 broad brown crossband at the cord; wing-apex broadly darkened 

 but the apical cells with pale centers; no distinct basal band. 



Male. — Length 4.6 mm. ; wing 5.2 mm. 



Rostrum slender, nearly as long as the remainder of the head, 

 black; palpi black. Antennae black. Head black. Pronotum and 

 mesonotum shiny coal-black. Pleura black, sparsely gray pruinose. 

 Halteres black. Legs black, the extreme bases of the femora very 

 slightly paler. Wings subhyaline; a broad brown crossband at the 

 cord, wing-tip brown, this coloration continued basad along the 

 veins as broad seams that extend almost to the level of the outer 

 end of cell 1st Mi, the centers of the cells being pale, the band along 

 the cord begins at the large oval stigma, continuing caudad but 

 becoming narrow and indistinct at the fork of Cu; the centers of 

 the cells in the wing-tip that are pale include cells Rz, Rs,, 2nd Mi 

 and Ms; there is no distinct basal band as in T. rostrata Enderlein, 

 merely a faint cloud in the base of cell Cu; veins dark brown. Vena- 

 tion: Sc long, Sci extending to just beyond midlength of Rs, Sci 

 alone being a little shorter than r; Rs long, arcuated; r on Ri+z 

 about half its length beyond the fork of Rs; Ri beyond r a little 

 longer than r; cell 1st M2 long and narrow, widened distally; basal 

 deflection of Cui beyond the fork of M, the distance about equal to 

 r-m. Abdomen coal-black. IVIale hypopygium with the pleural 

 appendages complex, consisting of three appendages; the outermost
