590 COLEOPTERA 



middle carina abbreviated in front. Antenna smooth, slender, two- 

 thirds the length of the elytra ; first joint moderate, third larger than 

 fourth and fifth separately, the latter a little longer than the following, 

 joints six to ten gradually decrease. Prothorax at least as long as broad, 

 somewhat smooth on the middle, truncated at its base with a rather 

 broad and short median lobe. Scutellum curvilinearly triangular. Elytra 

 depressed on the disc, strongly but gradually narrowed behind, with a 

 lobe on each at their base embracing the lobe of the thorax. Femora 

 gradually dilated, the posterior a little shorter than the elytra ; first 

 joint of the tarsi of the latter pair scarcely as long as the second and 

 third conjointly. 



Body partially pubescent. 



1028. N. (Oallidium) lineatum, Fabr.; Coptomma linea- 

 tum, White. Body polished, head fuscous, thorax and elytra rufous 

 indistinctly spotted with fuscous ; legs and scape of antennae reddish ; 

 apex of femora, tarsus and antennae, nigro-fuscous. The head has an 

 impressed line not extending to the occiput ; the frontal portion of the 

 head, except a smooth space on the centre, is covered with pale-yellow 

 hairs ; the hind part is smooth on the centre, the rest being clothed 

 with pubescence similar to that in front and forming two broad lines, 

 nearly contiguous on the vertex. The thorax is sub-conical, its base 

 bisinuated ; there is a broad pubescent line near each side, from base 

 to apex, of the same colour as those on the head, the dorsal space quite 

 smooth and nude, the sides nearly so, but bearing a few punctures near 

 the base. Scutellum short, triangular, pubescent. The elytra are 

 moderately long, wider than the prothorax at the base, elongate-obconi- 

 cal, apices conjointly rounded ; their surface is impunctate ; each bears 

 four longitudinal furrows, the sutural extending from base to apex, the 

 second and third from the base to near the apex are joined at the extre- 

 mities, the fourth is marginal ; these furrows are filled with pale-yellow 

 hairs. The legs and antennae are pubescent. The under-side, from the 

 eyes to the ventral segment, is more or less clothed with whitish hairs, 

 except the central longitudinal line. 



Length, 8 lines. 



I have seen none larger ; White's measurement is 9^. 



1029. N. (Callidium) SUlcatum, Fabr.; Coptomma acuti- 

 penne. White. The head bears two shallow longitudinal furrows, which, 

 in perfect specimens, are filled with whitish hairs ; the dorsal line, as 

 well as one on each side (between the antennae) appear somewhat 

 elevated and smooth. The thorax is subconical, a little incurved late- 

 rally in front of the middle, and rather deeply, but not widely, excised 

 at each side close to the apex ; the base has a central lobe and a less 

 obvious one midway between it and the posterior angle, which is sub- 

 acute and directed backwards ; the surface is impunctate, with a broad 

 smooth dorsal line, the spaces external to it being clothed with whitish 

 hairs, and very indistinctly depressed as broad lines. Scutellum sub- 

 triangular. The elytra are moderately long, widest at the base, from 

 whence they taper gradually to the apices ; the humeral angles are dis-
