154 Records of the Indian Miiseum. [Vol. VIII, 



a little darkening of the surface about the " pits," that is, in the 

 spots where the subcontiguous side stripes usually appear. 

 Viewed from behind, the thorax is a little darker and more brown 

 in colour. Scutellum, metanotum and sides of thorax more or less 

 concolorous ; palpi blackish; antennae brownish yellow. 



Abdomen.- — Dark brown above, with indistinct blackish mar- 

 gins to segments and a blackish side stripe ; belly dirty brownish 

 yellow. 



Legs. — Wholly brown or dark brownish yellow except coxae 

 and basal part of femora which are pale yellowish, the colour in 

 the latter darkening to brown by about the middle. 



Wings. — Quite clear; 5 posterior cells; petiole of 2nd posterior 

 cell shorter than the cell ; 4th posterior cell as long as the discal 

 cell; posterior cross-vein distinctly before the discal cell. Halteres 

 pale 3-ellow. 



Described from three 5 9 from Yembung (i 100 ft.), i3-i-i2; 

 in jungle, near plantain trees. 



In the two examples other than the tj^pe, the head and 

 thorax are much darker, but this is apparently due to their being 

 somewhat stained. 



Limnophila quartarius, mihi, sp. nov.

Head. — Occiput cinereous grey, or nearly ash grey; antennae

 forks at one fourth of its remaining length, the branches strictly 

 parallel, just suthciently turned upwards at their tips to make 

 them bisinuate; the 3rd vein springs from the 2nd (at the lowest 

 point of the downward curve of the praefurca), without any curve 

 or angle, and the anterior cross-vein is situated at the same spot. 

 The 1st posterior cell with strictly parallel sides; discal cell dis- 

 tinctly shorter than 2nd and 3rd posterior cells : posterior cross- 

 vein just after base of discal cell, but slightly variable in position.
