ochreous. Legs greyish ochreous ; all the femora with two 

 complete brown rings, on the front pair at i? and |, on the 

 middle pair at | and |, and on the hind pair at ^ and | of 

 the distance from base to apex of femora ; knees narrowly 

 brown ; tibiae with the apex dark brown, middle tibiae with 

 a distinct brown spot in the middle of the upper side (this is 

 only faintly visible on the other legs) ; tarsi light greyish 

 ochreous^ tips of first four joints light brown^ whole of last 

 joint blackish. fFm^f/s subhyaline, ochreous-tinged ; distinct 

 blackish spots on the small cross-vein, the two outer angles 

 of the discal cell, the junction of the great cross-vein with 

 the fifth longitudinal, and before the apex of the seventh ; 

 terminations of all the veins slightly clouded with fuscous. 

 Great cross- vein just before middle of discal cell. Seventh 

 vein with its tip bent downwards at right angles to the main 

 portion, a stump arising from the angle, which is nearly as 

 long as the terminal portion of the vein. Halteres uniformly 

 ochreous. Abdomen dark greyish ochreous, all the segments 

 with narrow brown apical bands. There is a continuous 

 median longitudinal brown band, which looks as though it 

 were due to the presence of food in the gut. Genitalia with

 but it will be useful to retain this latter name as a subgenus, 

 including those species with four posterior cells, Trentepohlia 

 in this restricted sense having only three. The two sections 

 are closely allied, and no doubt are best included under one 

 genus. I have compared balsam preparations of the 

 genitalia of these two Ceylon species, and tliev are very
