at the tip; tibiae brown soon ])assing into dark brown; tarsi dark l)rown; legs 
densely hairy. Wings rather narrow, grayish; distinct brown clouds along 
the cord and outer deflection of cell 1st M2; veins dark brown. Venation as in 
plate II, fig. 8. 
Abdominal segments dark l)rown, the lateral margins narrowly and abruptly 
pale; hypopygium reddish; alidomen provided with numerous long pale hairs. 
Habitat. — Ecuador, Peru. Holotype, cf, Alaousi, Ecuador, 
altitude 9450 feet, June 17, 1914 (Parish coll.). Paratype, 6^, 
Matucana, Peru, altitude 7788 feet, July 14, 1914. 
Similar to the North American T. anomala Osten Sacken'^ 
but the thorax is much clearer gray, the head gray instead of 
brownish, the wings graj^ instead of brown, the cell 1st Mz 
smaller and the veins issuing from it much longer. I would have 
identified this with the LwinophiJa trichopus Philippi,-^ but the 
latter is described as having five posterior cells to the wings.
