CURCULIONIDjE. GRONOPS. 89 



Genus CCCVII. — Gbonops, Schonherr. 



Antemice geiiiculated, 12-jointed, short, rather stout, the scape not touching the 

 eyes; funiculus 7-jointed, its basal joint somewhat elongated, obconicj the 

 five following very short, nodose, coarctate, gradually thickened; the seventh 

 very thick; club large, stout, ovate. Rostrum somewhat elongate, robust, 

 deflexed: eye* oblong, large, lateral : thorax subcylindric, deeply emarginate 

 anteriorly, somewhat bisinuated at the base, lobate behind the eyes : elytra 

 oblong, slightly convex, deflexed posteriorly, costated, the costs terminating 

 in a callus, the apex rounded, covering the pygidium, the shoulders an- 

 gulated: legs rather long, stout, approximating at the base ; Jemora clavate, 

 unarmed : tibice rather short, straight ; the apex with a minute hook ; tarsi 

 slender. 



This singular genus may at once be known from all the in- 

 digenous genera by its costated elytra and deeply emarginated 

 anterior edge of the thorax: it greatly resembles the genus Bogoiis; 

 but from that genus it differs by having the tibiae straight, with a 

 minute hook at the apex, and the rostrum differently constructed : 

 — the species frequent sandy places. 



Sp. 1. lunatus. Plate xx. f. 5. — Niger, dense cinereo-squamosus, thorace tri-
