impression,and then suddenly effaced; metathorax rugose, reticulate. 
Stigma either linear, elongate, attenuated, emitting the radial nervure 
before one-third of its length, or else forming an elongate triangle, 
and emitting the radial nervure just before the middle ; radial ner- 
vure describing a regular curve, without sinuation ; radial areolet 
narrow, elongate, remote from the tip of the wing; recurrent nervure 
more or lessrejected, when it is much thrown back, the first cubital 
areolet becomes a hexagon ; 2nd discoidal areolet complete. Ab- 
domen subsessile; Ist segment striolate, the rest smooth, minutely 
ciliate along the hind border. Terebra very short. 
Haliday was acquainted with three species, to which I 
am now enabled to add a fourth, distinguished by its 
neuration, ‘They are closely allied to the preceding and 
the following genus, and are found in similar situations, 
such as the banks of rivers and ponds, or among the 
rejectamenta of the sea-beach. ‘Their earlier states are 
not known.
