Headobloiijj or horizontal, with a profound frontal sulcus, the angles 

 of whicli are acute; occiput broad, rcninded; ocelli S. 



Antennse, in 9 , 12-jointed, clavate-subnioniliforni, the pedicel very 

 small, rounded; the scape short, stout; in S, 14 jointed, filiform; the 

 scape usually angulated a little beyond the middle; the pedicel rounded 

 but larger than th(^ tirst flagellar joint. 



Maxillary palpi o jointed, 



iMaiidibles prolonged, rostriform, dentate. 



Thorax : Prothorax visible from above; mesonotum with two furrows, 

 slightly converging posteriorly; scutellum rather large, somewhat tiat 

 or subconvex, with a grooved line along the sides and bifoveated at 

 base; metathorax emarginated at apex, the lateral angles acute. 



Frcmt wings folded, often emarginate or with a slit at apex, pubes- 

 cent, the snbmarginal vein not developed or terminating before attaining 

 tl'e costa; the basal cell incomplete; the basal vein obsolete or at least 

 water-lined. 



Hind wings veinless. 



Abdomen i)cti<dated ; in 9 ovate, in S oblong-oval, composed of ap- 

 parently but 2 or 3 segments, the second occupying most of the surface 

 and generally inclosing the apical segments, with a sulcus at base; 

 petiole longer than thick, grooved. 



Legs rather short, the femora stont, the tibijv clavate, their spurs 

 weak; basal joint of hind tarsi about one-third h)nger than the second; 

 claws small, simple. 



In the oblong horned head, the rostrate mandibles, and the shape of 

 the scape, this genus is quite distinct from all others in the group. 



The genus Coptera Say, is without doubt identical, and was recog- 

 nized as synonymous by Mr. A. H. Haliday as early as IS.")! ; besides 

 I have identified his tyi^e, Coptera polita, which proves to be nothing 

 but a small Galesus with emarginated and folded wings.
