Head without frontal tubercles, the front transverse. Antennae very 

 slender, at least nearly as long as the body. E'ore wings with the stig- 

 matic vein arising from the middle of the stigma. Cubital vein twice 

 forked, the first time at a moderate distance from its origin, which is 

 at or a trifle outside the middle of the space between the first oblique 

 and stigmatic veins, the second time opposite or scarcely beyond the 

 base of the stigmatic vein. Second oblique vein arising nearer the first 

 oblique than the cubital vein biit at varying relative distances, always 

 close to the first oblique vein, the first discoidal cell between them 

 being four or five times broader on the hind margin than at base. 

 Legs slender, varying in length but shorter than the fore wings. 

 Abdomen ovate. 



Some specimens seem to show a short stout cauda, which others 

 appear to lack, and occasionally short cornicles may be detected which 

 are apparently of uniform diameter. 



Three species of the genus have been described, all found at Floris- 

 sant, Colorado, but one of them first published from British Columbia. 

 It is re-desci"ibed with some changes below.

The remains which are preserved are a pair of overlapping fore wings 

 with torn edges, but with all the im2:)ortant parts of the neuration, and 

 some of the veins of the hind wings. The body is completely crushed 

 and all other members are absent. The parts which can be studied 

 are thus very similar to those found in Gerancon )y<^trorum from the 

 same bed. Owing to the absence of the margin, the shape of the wing
