sparsely spotted with brown ; a conspicuous brown area at 

 the stigma, continued caudad along the cord as a seam ; 

 a brown seam at m ; conspicuous brown spots at the wing- 

 margin at the ends of veins R^^z^ J^i+h-, Mu^^, M.^, Cmj, Cu2, 

 and the anal veins ; small brown spots at arculus, origin of 

 Rs and SC2; veins pale yellow, brown in the infuscated areas. 

 Venation : somewhat as in the genus l^eucholabis ; Sc long, 

 Sci ending a little beyond mid-leugth of Rs, Sc^ at the tip of 

 Si ; Rs long, gently arcuated ; r about its length beyond 

 the fork o£ Rs ; R^ beyond it about one-half of r ; deflection 

 of i?4_f.5 feebly angulated at mid-length ; 7?2+3 and R^^^ 

 diverging at wing-margin, so cell R^ is trumpet-shaped ; cell 

 1st M2 very long, longer than Rs or any of the veins beyond 

 it; jji less than one-half the outer deflection of M^; r-m on 

 il^i+o about its own length beyond the fork of M; basal 

 deflection of Cui just beyond the fork of M. 



Abdomen dark brown, the subterminal tergites con- 

 spicuously yellow. Ovipositor with the valves yellow, 

 flattened, upcurved to the acute tips.

 ivood) . 



Type in the collection of the British Museum (Natural 

 History). 



Limnobia (?) teucholabina is a species of very doubtful 

 generic position. The type-specimen is a female in indif- 

 ferent condition. Mr. Edwards had arranged the fly in the 

 genus Teucholabis, which it resembles in a rather striking 

 manner, but there seem to be but fourteen antenna! segments. 

 Until more material is available, it seems best to place this 

 very interesting fly as an aberrant Limnobia, with the indi- 

 cation that it will probably be found to represent a new 

 generic or subgeneric group when more specimens come to 

 hand. 



Libnotes subaqualis, sp. n. 



General coloration yellow, pronotum and mesonotal pia^- 

 scutum with a median darker stripe ; tips of femora pale ; 

 wings greyish yellow, the costal and stigmal regions more 

 strongly yellowish ; Rs short, straight, in alignment with 

 the remaining elements of the cord ; abdominal tergites 

 bicolorous. 



Male.— Length 8 mm. ; wing 9 mm.
