told by the position of the basal deflection of Cuj, which is 

 here situated at midlength of cell 1st M2 instead of before 

 the fork of M as in Limnophilella. The petiole of cell Mj 

 is very short to almost lacking so that cell Mj is excedingly 

 deep. 



Limnophila (Anstrolimnophila) eutaeniata Bigot. 



1891 Mission Scientifique du Cap Horn, 1882 — 1883, vol. 6, Zoologie, part 2. 



pp. 9, 10, pl. 2, fig. 3. 



Male. — Length 15 mm.; wing 16 mm.; antenna, about 

 7,8 — 8 mm.; halteres about 2,7 mm.; före leg, femur, 9,8 mm.; 

 tibia, 12,2 mm.; me tatarsus about 12 mm. 



The bands on the wing include one at the wing-base, 

 one at the level of the origin of Bs, one at the level of the 

 cord and one at the level of the outer end of cell 1st M2, 

 the two last confluent in cells E3, B5, and 1st M2 leaving a 

 clear area in the middle of the last named cell; the wing- 

 apex in cells R2 to 2nd M2 is darkened. Bigot shows the 

 species as having a complete cross-vein at the origin of the 

 sector, connecting it with M\ this is not so in the present 

 specimen where the sector is merely spurred. The male 

 hypopygium has the ninth tergite heavily chitinized and 

 shiny, interrupted only on the mid-dorsal line. 



One male, Rio Azopardo, near Admiralty Sound, Tierra 

 del Fuego, March 1896 (Ohlin).
