Cu. sulculus. KirbyC?) MSS.—Ne. sulculus. StepL Catal. 154. No. 1557. 



Black, sparingly clothed with cinereous pubescence above, with the suture 

 posteriorly and the body beneath densely clothed with whitish scales : thorax 

 somewhat convex, deeply channelled down the back, the lateral margin with 

 an obtuse tubercle, the base subtruncate: elytra obsoletely crenate-striate, 

 the interstices lineated with cinereous, the shoulders slightly prominent. 



The small size of this insect, combined with the whitish posterior portion of the 

 suture of the elytra, deeply channelled thorax, &c. sufficiently distinguish it 

 from its affinities. 



Found near London, in Suffolk, Norfolk, &c. : apparently not 

 very common. 



Sp. 15. phgeorhynchus. Nigricans, vellere argenteo-cinerascenti, elytris obso- 

 letiiis striatis, thorace bituberculato, rostro ferrugineo. (Long. corp. 1 Un.) 



Cu. phaearhynchus. Marsham. — Ne. phseorhynchus. Steph. Catal. 154. No.

Dusky or brown black, clothed throughout with a silvery down, above tinged 

 with cinereous, beneath pure white : thorax slightly convex, its sides each 

 with an obtuse tubercle, the base truncate: elytra faintly crenate-striated, 

 the interstices lineated with cinerascent-silvery hairs : antennae black, with 

 the club ashy : rostrum ferruginous. 



The ferruginous rostrum and silvery pile on the body, exclusively of other 

 characters, will at once point out its more prominent distinctions from the 

 other species of the genus.

 Mr. Millard in the nursery gardens near Fynone." — L. W. D'llhoyn,
