 brevissimus ; secundus globosus ; tertius et sequentes lineares. Ala- 

 rum venae tantum pubescentes ; areolse externse quinque, secunda 

 petiolata, quinta incompleta ; costales tres ; brachiales duas, alas me-

Body nearly bare. Antennas slender, pubescent ; first joint very 

 short ; second globose ; the rest linear ; discal areolet incomplete ; 

 veins only pubescent ; mediastinal vein nearly one-third of the length 

 of the wing, forked and angular at its tip, and thus connected with 

 the costa and the subcostal vein ; subcostal about three-fourths of the 

 length of the wing ; radial emerging from the subcostal opposite the 

 tip of the mediastinal, forked a little beyond two-thirds of the length 

 of the wing ; cubital emerging from the angle of the transverse veiniet 

 which bounds the praebrachial areolet, and ending at the tip of the 

 wing ; subapical ending on the hind border, forked at a little beyond 

 half the length of the wing ; externo-medial proceeding from the trans- 

 verse veiniet which bounds the pobrachial areolet ; anal complete ; axil- 

 lary and subaxillary imperfect. Areolets twelve, the humeral, the 

 subcostal, the mediastinal, two radial, the cubital, the prsebrachial, 

 which is rather less than half the length of the wing, the pobrachial, 

 which is much shorter than the prsebrachial, the subapical, two externo- 

 medial, and the axillary, from which the subaxillary is hardly distinct. 

 Posterior margin not excavated nor indented towards the base. 

 Larva unknown, probably aquatic.
