light yellow ; femora pale brown, the bases paler, the tips 

 dark brown ; tibiae and tarsi dark brown. Wings very 

 indistinctly pale grey, only the stigma indistinctly pale 

 brown, oval in outline ; veins dark brown. Venation : 

 agreeing most nearly with P. frugi in that the basal 

 deflection of Cu x is far before mid-length of cell 1st M 2 ; 

 Rs longer than R 3 ; R 2+3 longer and more arcuated than in 

 frugi ; r on R 2 immediately beyond the fork of i2 2+3 ; Ri 

 beyond r a little longer than this cross-vein alone ; cell 

 1st M 2 small, shorter than the petiole of cell M x ; cell Mi a 

 little shorter than its petiole ; basal deflection of Cu x at 

 about one-quarter the length of cell 1st M. 2 . 



Abdomen light brown.

Pseudolimnophila senex, sp. n. 



Male. — Length 9*5 mm. ; wing 10 mm. ; hind leg, femur 

 9*1 mm., tibia 9 mm. 



Related to P. frugi (Bn'groth) of South Africa, but very 

 much larger, differing moreover as follows : — 



Pleura more plumbeous ; legs entirely pale brownish 

 yellow, the tips of the femora not darkened ; wings with a 

 strong greyish suffusion. Venation : r considerably removed 

 from the tip of 7? 1? the latter being twice the length of r 

 alone ; vein R 2 running generally parallel to R : < for its entire 

 length so that cell 2nd R x is much wider at the wing-margin 

 than cell P 2 ', deflection of -Ri + .-, about equal to r-m ; petiole 

 of cell M x unusually short, less than one-half cell M x ; cell 

 1st M 2 longer than vein Cu { beyond it ; basal deflection of 

 Cu x at about one-fourth to one-fifth the length of cell 

 1st M 2 ; pleurites of the male hypopygium long and slender.
