LIMNOBIA. 283 



SECTION 1. 



a. Wings with a discal areolet. 



b. First externo-medial vein forked. Radial vein forked. 



c. Fork of the first externo-medial vein with a petiole between it and the dis- 

 cal areolets. 

 d. Two veinlets between the subanal vein and the third externo-medial. 



This division comprises two very dissimilar sections. 



Antennae of the male longer than the thorax. Wings not dilated ; 

 mediastinal vein ending far before two-thirds of the length of the wing, 

 joined to the subcostal by a veinlet very near its tip ; subcostal ending 

 at about four-fifths of the length ; radial and cubital springing from a 

 common petiole, which they rather exceed in length, and which pro- 

 ceeds from the subcostal at a little before half the length of the wing, 

 and forms ^ nearly right angle, rejecting a rudimentary vein at its base ; 

 radial forked beyond one-fourth of its length; cubital joined near its 

 base to the third externo-medial by a veinlet, whose angle emits the 

 first externo-medial, the latter is forked at two-thirds of its length, and 

 is connected with the third externo-medial by a veinlet, whose angle 

 emits the second externo-medial; third externo-medial connected with 

 the subaual by two veinlets, one before half the length of the wing, 

 the other much before the middle of the discal areolet ; subanal curved 

 abruptly to the hind border; axillary slightly undulating; discal areolet 

 hexagonal, more than twice longer than broad.

Hoaiy. Palpi and antennae black. Wings nearly limpid; their 

 borders adorned with grey spots which almost meet in the disc. Halteres 

 testaceous, with black knobs. Abdomen tawny, with a black band on 

 the hind border of each segment. Legs black; femora testaceous 

 towards the base. 



Rare. Inhabits moors. (E. S. I.)

 apice fuscis. Long. 2f-3 lin. 



Cinereous. Palpi and antennas black. Thorax hardly spotted. 

 Winys slightly cinereous, with three brown costal spots at equal distances 

 from each other ; transverse veinlets slightly clouded. Halteres pale. 

 Legs yellowish ; femora, tibiae, and tarsi with brown tips.
