This fine new Priouid might, at first glance, be taken for a Pyrodes, 

 in consequence of its metallic colour and general form ; it belongs, 

 howBTer, in reality to a different section of the family. But it has no 

 close relationship to the metallic Fsalidognathi of the same section, 

 having more real affinity with Ctenoscelis, in spite of its very different 

 facies. In the sculpture of the thorax of the (?, as well as in the 

 form of the mandibles, and to a great extent also of the antennae, it 

 closely approaches G. ater ; from which it differs in the form of 

 the thorax, especially in the long lateral spine ; in the quite different 

 shape of the same organ in the $ , and in the only partially and 

 minutely denticulated tibiae. As Mecosartliron in the sub-family 

 CtenoscelincB presents some approximation to it in the length of the 

 thoracic spine, our new genus may 2)erliaps be admitted into the same 

 group.

A pair of this handsome and remarkable Longicorn were brought 

 home by their captor, Herr Wallis, who took them at Frontino, on the 

 Cauca side of the Central Cordillera in New Granada. The general 

 colour is dark coppery-brown or black, the elytra (especially in the $ ) 

 being most metallic. Owing to the dense and fine sculpture, the surface, 

 though without pubescence, is scarcely shining. The thorax in the <y 

 is considerably wider tban the elytra, and its width is moi'ethan double 

 its length. Anteriorly, it is not deeply emarginate to receive the head, 

 and the anterior angles are broadly truncated ; from the exterior end 

 of the truncature it rather rapidly widens (with crenulated edges) to 

 the very acute lateral spine placed much behind the middle, whence it 

 rather suddenly narrows to the basal angle. The surface is very 

 minutely punctulate and opaque, except for the scabrous shining lines, 

 of which there axe two running along the disc from the fore to the 

 hind margin (each dilated in tbe middle), and one on each side extending 

 from the lateral spine to the disc, and thence abruptly bent towards 

 the base. The thorax in the 5 is equally short, but miich narrower;
