the origin of Rs and the wing-apex more suffused with brown, 

 the basal half of the costal cell pale ; veins beyond the cord 

 in the radial and medial fields with series of small pale 

 brown dots, somewhat after the fashion of Conosia irrorata ; 

 larger, dark brown spots along the costal margin at Sc 2 , Sc x , 

 B : , R 2 , and R 3 . Venation : Sc 2 retreated some distance 

 from the tip of Sci, Sc 2 being at about one-third the distance 

 between the origin of Rs and the tip of Sci ; r on R 2 at 

 about its own length beyond the fork of R 2+s ; R? + z about 

 equal to the basal deflection of Cu x ; cell 1st M 2 closed ; 

 m transverse ; inner end of cell 1st M 2 narrowed ; basal 

 deflection of Cu x before the fork of M, the distance about 

 equal to r-m ; 2nd Anal vein sinuous, as in the subgenus 

 Erioptera. 



Abdomen broken. 



Hub. British East Africa. 



Holotype, sex?, Kericho, altitude 5500 feet, November 1, 

 1912 (R. B. Woosnam). B.M. no. 1914. 2. 



Type in the collection of the British Museum (Natural 

 History). 



The unique type above described is in poor condition, one 

 wing and the abdomen being lost. The well-marked 

 characters diagnosed above will render the species easily 

 recognizable. The type is pinned on the same pin with a 

 paratype of Limnophila diffusa. 



Erioptera ignava, sp. n. 



Head dark grey; mesonotal pnescutum yellow with three 

 reddish-brown stripes; scutellum dark brown; postnotum 

 with a median brown line ; pleura with a broad dark brown 

 dorsal stripe and a slightly narrower yellow ventral stripe, 

 wings long and narrow, greyish yellow ; cell 1st M 2 closed, 

 vein 2nd A straight. 



Male. — Length 5*8 mm. ; wing 5*7 mm. 



Female. — Length 6 mm. ; wing 6"2 mm. 



Rostrum varying from light to dark brown. Antennae 

 dark brown, the scapal segments slightly paler brown. 

 Head dark grey, the vertex surrounding the eyes pale 

 brownish yellow, in some cases forming a U-shaped mark 

 behind the antennas with the arms of the U directed back- 

 ward ; posterior region of the vertex with numerous, stiff', 

 subproclinate bristles; eyes small, broadly separated both 

 above and below. 



Pronotum moderately prominent, light yellow, the scu- 

 tellum with a shiny median area ; procoxse large, practically 

 contiguous. Mesonotal prsescutum yellow with three reddish- 

 brown stripes, the lateral margins of the sclerite brighter;
