216 MANDIBULATA. COLEOPTERA. 



Genus CCCLVIII. — Mycterus, Clairville. 



Antennae fiKform, inserted before the eyes on the rostrum, composed of rather 

 short, obconic, slightly serrated articulations, of which the terminal one is 

 acute and apparently articulated^ and the second shortest. Rostrum elongate, 

 slender: palpi with the terminal joint compressed, somewhat acute: body 

 ovate, covered with a silken down : thorax trapeziform, broadest behind : elytra 

 rigid: abdomen robust: /eg-* rather long, furnished with minute spurs: tarsi 

 with the penultimate joint bifid. 



One species only of this genus is known, which is found on 

 flowers, and may be readily known by its elongate rostrum, upon 

 which are inserted rather elongate filiform antennae, the articulations 

 of which are obconic. 



Sp. 1. griseus. Plate xxi. f. 4. — Niger, supra griseo-Jlavescens, infra griseo- 



argenteo nitiJus, rostro bistriato. (Long. corp. 3f — 4.3 lin.) 

 My. griseus. Clairville.— Steph. Catal. 194. No. 2001. 



Black, antennae and legs the same, clothed above with a griseous-yellow pile ; 

 and beneath with a shining griseous-silvery pubescence : rostrum with two 

 impressed longitudinal approximating striae. 



Extremely rare in Britain ; I possess a pair that were captured 

 near Kingsbridge by the late Mr. Crancli : others are in the collec- 

 tion at the British Museum, taken at the same time, in June, 1815. 



Genus CCCLIX. — Salpingus, Illiger. 



AnienncE rather short, clavate, the basal joint robust, globose, the two following 

 of nearly equal length, obconic, the succeeding two rather stouter, nodose, the 

 remainder forming an elongate five-jointed club, the three first joints of which 

 are transverse semi-globose, and the terminal one subovate acute. Palpi fili- 

 form, with the terminal joint rather thickened and obtuse : labrum quadrate : 

 head depressed, produced anteriorly into a rostrum, which is generally a little 

 elongate, and contracted in the middle: thorax subcordate, narrowed behind, 

 the lateral margins entire : elytra rigid : body oblong-ovate, glabrous, with the 

 head and thorax considerably narrower than the elytra. 



Exclusively of the general habit, Salpingus differs from the fol- 

 lowing genus by having the rostrum more elongate, somewhat 

 slender and contracted in the middle, with the antennae, which are
