Caput antice breve^ porrectum, postice angustius. 

 Oculi magni, supra emarginati, Antennm setaceae, 

 corpore longiores, basi distantes ; scapo breviusculo, 

 articulo secundo brevi, tertio et quarto longissimis, 

 sequentibus paulo decrescentibus. Prothorax de- 

 pressus, transversus, basi lobatus. Elytra elongata, 

 subangusta, apicibus paulo acuminatis. Pedes de- 

 biles, antici breviores ; femora compressa ; tihice 

 rectas ; tarsi postici et intermedii articulo basali 

 elongato. Goxce antic^e et intermediae eductaj, con- 

 tiguae. Ahdonien molle, segmentis aequalibus. 

 The males appear to have narrower elytra, and nearly 

 cylindrical abdomens ; in the females the latter are more 

 triangular. There is a very distinct tubercle on each 

 side of the prothorax in N. tibialis, and it is also pre- 

 sent although much less distinctly in N. ignavvs. In 

 N. ovatiperinis the tubercle is replaced by a broad, but 

 very slight and scarcely more than perceptible promi- 

 nence. The antennary tubercles form an almost con- 

 tinuous projection across the front. 



* The palpi iu most of the geuera of Ceramhycidce. have the last joint 

 more or less triangular. 



f One of these {Comusia, Thorns.) is not in Mr. Wallace's collection, 

 its species {ohrioides) is a rather large insect, of a pale and livid testa- 

 ceous, vrith a clear brownish-black band near the middle of the elytra. 

 It is unknown to me, but M. Lacordaire says that it is as different as pos- 

 sible from an Ohrium. 



X Di". Leconte has subsequently published a genus which he has named 

 " Noserus."
