with a broad black vitta in the middle^ and another still broader 

 on each side above the sockets of the haunches. Elytra elon- 

 gated, depressed, with the sides nearly parallel, obliquely trun- 

 cated at the apex, with the external angle of the truncature pro- 

 duced and acute ; surface thickly punctured, sooty black, with 

 an indistinct pale streak in the middle of the base on each side. 

 Body beneath black, with the exception of the pro- and meso- 

 sterna, which are yellow. Legs black, coxae and base of thighs 

 yellow ; thighs slenderly clavate ; tarsi slender, the basal joint 

 elongated. 



One example, taken at Para. 



4. Lepturges complanatus, n, sp. 



L. oblongus, depressus, carneo-griseus, fusco maculatus : thoracis 

 spinis lateralibus angulos posticos constituentibus : elytris apice 

 singulatim rotundatis. Long. 3^ lin. <S . 



Head black. - Antennae reddish, with the extreme tips of all 

 the joints dusky. Thorax blackish, clothed with ashy change- 

 able pile, the lateral spines coincident with the posterior angles. 

 Elytra oblong, broadly rounded at the tips, plane above and 

 thickly punctured, with a slight indication of two longitudinal 

 raised lines on each, pinkish grey in colour, with five dark brown 

 spots or patches, — namely, one, minute, under the humeral angle; 

 one, linear-oblique, in the middle of the base; a third, subtri- 

 angular, on the side near the base ; a fourth extending as a broad 

 irregular fascia nearly to the suture ; and a fifth, wedge-shaped, 

 near the apex. Body beneath and legs dusky. Front and 

 middle thighs thickly clavate; hind thighs more slender. Tarsi 

 moderately elongated.

5. Lepturges amabilis, n, sp. 



L. oblongus, depressus, griseus : thoracis spinis lateralibus prope

Head sooty black. Antennae greatly elongated, pitchy black.

 space only intervening between them and the hind margin. 

 Elytra oblong, very slightly narrowing towards the apex, which 

 latter is obliquely and briefly truncated ; the surface is slightly 

 depressed and closely punctured ; the colour is clear grey, with 

 (on each) four black spots, — namely, one, oval-oblique, in the 

 middle of the base ; a second, elongate-bilobed, on the side near
