(Typo G. foniiitiie Panz.) 



Head oblong" or lioiizontnl, with a profound frontal sulcns, tlieanole.s 

 of which are acute; occiput broad, rounded; ocelli 3. 



Antenna?, in 9 , 12-jointed, clavate-subniouiliform, 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 the first flagellar joint. 



Maxillary palpi 5-jointed. 



Mandibles prolonged, rostiiform, dentate. 



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

 slightly converging posteriorly; scutellum rather large, somewhat fiat 

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

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



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

 cent, the submarginal vein not developed or terminating before attaining 

 the costa; the basal cell incomplete; the basal vein obsolete or at least 

 water-lined. 



Hind wings veiuless. 



Abdomen pctiolated ; iu 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 stout, the tibia^ clavate, their spurs 

 weak; basal joint of hind tarsi about one-third hmger than the second; 

 claws small, simple. 



In the oblong horned head, tlie<ostrate 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 1857; besides 

 I have identified his type, Coptera polita, which i)roves to be nothing 

 but a small Galesus with emarginated and folded wings.
