the suture; rostrum stout, very little bent, and of very nearly uniform width through- 

 out ; the apex only rufescent ; sides of the thorax very little rounded ; elytra distinctly 

 striated; antennEe and legs testaceous ; the femora naore or less clouded with dusky, 

 rarely entirely dark. More elongate than the preceding species, and is readily dis- 

 tinguished by its rostrum being stouter (the greater part dark coloured), less bent and 

 having the apex not attenuated. The scales on the elytra are, moreover, of three 

 distinct forms, whereas in T. junceus there is scarcely a perceptible difference in any 

 of the scales. In the preceding species the anterior tibiae are unarmed in either sex: 

 in the following four species the anterior tibiae of the males have a tooth or spine on 

 the middle of the inner side. 



8. T. Schneideri (Herbst), Schonh. Oblong, rather broad and but moderately 

 convex ; pitchy black ; above prelty densely clothed with piliform, and for the most 

 part ash-coloured scales, with broader white scales along the middle of the thorax, 

 most abundant behind, and with broad snow-white scales on the suture of the elytra ; 

 antennae at the base, tibiae and tarsi ferruginous ; rostrum thickish, bent and cylin- 

 drical ; femora but little inciassated. The alternate interstices of the strife of the 

 elytra are often paler (sometimes whitish) than the others. The toolh on the anterior 

 tibiae of the male is but little prominent, smaller, shorter and less convex than in 

 T. polylineatus ; general hue darker, being of a plumbeous gray; the scales much 

 narrower, and furthermore distinguished by the unarmed femora and by the toothed 

 anterior tibias of the male. 



9. T. Meliloti (Kirby), Stephens, Germar, Schonh,, Walton. Oblong, pitchy black 

 (the apex of the elytra often rufescent), above clothed with yellowish elongated scales ; 

 rostrum arched, attenuated, and the part anterior to the antennae somewhat depressed ; 

 antennae, tibiae and tarsi, as well as the apex of the rostrum testaceous; thorax con- 

 stricted in front; the sides nearly parallel; elytra distinctly striated, and with the 

 humeral angles rather prominent; legs, comparatively, rather slender; the anterior 

 tibiae with an acute tooth on the inner side, in the male sex. About equal in size to 

 T. tomeutosus and Miccotrogus picirostris, but a little broader than the last-mentioned 

 insect. 



10. T. m(/nVos<m, Walton Catal. (T. Zz6iaZis, Schonh. i*). Oblong, black, rather 

 sparingly clothed with subpiliform ashy white scales ; the scape and first joint of the 

 funiculus of the antennae, the tarsi and apical portion of the tibiae rufo-testaceous ; 

 rostrum rather slender, linear and but little arched ; elytra distinctly striated. Male 

 with an acute tooth on the inner side of the anterior tibia. Of the very narrow 

 scales on the elytra of the insect there are usually but two rows on the interstices of 

 the striae, and viewed under an ordinary lens the elytra appear to have whitish striae ; 

 on the striae themselves is a single row of still more slender scales ; the posterior 

 margin of the thorax is edged with broader white scales, and similar scales are 

 scattered along the suture. In size, form and general appearance extremely like 

 Miccotrogus picirostris. Schonhen's description of T. tibialis agrees very closely 

 with this insect, but no mention is made of the dentate tibias of the male ; possibly he 

 only possessed the female. 



11. r. 6reutcorwis (n. sp.). Minute; oblong, black, rather sparingly clothed with 

 very narrow scales as in the preceding species ; the base of the antennae (including the 

 scape and two of the joints of the funiculus), the tibiae and tarsi rufo-testaceous ; the 

 third joint of the funiculus slightly transverse, the others gradually broader, though 

 scarcely longer, the last joints very strongly transverse. Anterior tibiae (in the male?)
