Family GERAPOMPID.?^:, now family. 



The forms of this group are rather closely allied to the euca?nids; 

 yet the costal area of the front wing- appears more reduced and is sup- 

 planted l)v a great number of branches extending forward from the 

 radius. Here, also, the radius and media are crowded back by tlie 

 strongly developed cubitus. The anal area is marked off by a curved 

 fold, Prothorax elongated.

Scudder regarded this form, which is to be considered the type of 

 the g-enus, as a homothetid (neuropteroid Pahvodictyoptera).

Length of the front wing, 27 mm.; breadth, 11 mm. 



The form of the wing is almost elliptical, with strongly arcuate ante- 

 rior l)orderand broadly rounded outer margin. The subcosta extends 

 not far beyond the middle 

 of the wing and sends off 7 

 in part simple, in part com- 

 pound veins to the anterior 

 margin. The costal area 

 is more band shaped and 

 narrower than in Eacsenux. 

 The radius proceeds in an 

 almost straight course to 

 the anterior border and 

 sends off' about a dozen 



oblique twigs directed forward; the sector arises in about the middle 

 of the wing and forms a single fork. The media separates into 3
