14 MANDIBULATA. — COLEOPTERA. 



Apparently rare ; I possess one example which was taken in 

 Norfolk, and others captured in June, 1827, near Ripley, by my- 

 self: — they differ greatly from each other; and from Gyllenhal's 

 description it appears to be a variable insect. 



Genus CCLXXVIL— Rhinusa, Kirhy. 



Jwferawa? geniculated, lO-jointed^ short, somewhat stout: funiculus 5-jointed, 

 its two basal joints obconic; the remainder transverse; club 4-jointed, 

 ovate. Rostrum free, more or less curved, its apex generally attenuated : 

 thorax transverse : elytra somewhat depressed, subquadrate, not covering the 

 apex of the abdomen : legs short ; anterior tibice with a minute hook at the 

 apex. 



Rhinusa, which has the antennae 10-jointed, is distinguished 

 from the immediately allied genera, by having the rostrum more or 

 less attenuated at the apex, not inserted, during repose, in a groove 

 beneath the thorax, the elytra depressed, subquadrate, and not 

 covering the apex of the abdomen ; and the anterior tibiae are 

 furnished at the tip with a minute hook :— the species frequent 

 flowers. 



Sp. 1. Antirrhini. Nigra, dense griseo-jmbescens, rostro recto, apice attenuato, 



femoribus obsolete dentatis. (Long. corp. 1^ — 1§ lin.) 

 Cu. Antirrhini. PaykuL—Rh.. Antirrhini. Steph. Catal. 150. No. 1509. 



Ovate, black, densely clothed with short griseous-white pubescence, rostrum 

 straight, attenuated at the apex : head gibbous behind : thorax somewhat 

 rugosely granulated : elytra punctate- striate, the interstices rugulose, with a 

 series of rather long griseous pubescence : femora clavate, the posterior ob- 



soletely dentate. 



Found within the metropolitan district, and in Norfolk in June, 

 in the flowers of the Antirrhinum Linarise ; not very abundantly. 



Sp. 2. intaminata. Oblonga, tenuis, niger, pubescens, rostro recto, apice attemiato, 



femoribus muticis. (Long. corp. | — 1^ lin.) 

 Rh. intaminata. Kirby MSS.— Steph. Catal. 150. No. 1511. 



Oblong, slender, pubescent : rostrum straight, with the apex attenuated : thorax 

 finely granulated : elytra striated, the interstices finely rugose and striated 

 with cinereous down : femora slightly clavate, imarmed.
