cJ. Head elongated behind the eyes and gradually narrowed 

 backwards, but becoming parallel- sided, thus forming a sort of 

 neck near the occiput ; eyes transverse, smaller and less prominent 

 than in Cyrtonops ; mandibles with a truncate but rather short 

 edge at the apex, each with an inner tooth between the middle 

 and base ; maxillary palpi normal, longer than the labial ; sub- 

 mentum short but distinct. Antennae inserted very close to the 

 base of the mandibles, extended to the middle of the elytra, 

 sparsely pubescent ; first joint not more than half as long as the 

 head, slightly curved, gradually thickened towards the apex; 

 third joint nodose at the apex, shorter than the fourth ; fourth 

 to eleventh subcanaliculate beneath. Prothorax subcylindrical, 

 longer than broad, slightly rounded at the sides. Mesonotum 

 with stridulatory area divided by a median impressed line. 

 Elytra strongly punctured in longitudinal rows. Femora strongly 

 thickened, the hind pair much longer and thicker than the others; 

 tibiae sharply angulate at the apex on the outer side, the middle 

 pair with a sinus, thickly beset with setae on the outer margin 

 below the middle, the hind pair deeply notched on the inner 

 side close to the apex. Prosternum moderately broad between 

 the coxae, dilated behind to meet the epimera, the acetabula, which 

 are rounded on the outer side, are thus completely closed behind. 

 Mesothoracic epimera shut off from the acetabula by a lateral 

 prolongation of the metasternum. Episterna of inetathorax very 

 narrow, acuminate behind. 



This remarkable genus, of which only a single species is known, 

 constituted one of Lacordaire's tribes of " Aberrant Cerambycides." 

 But, like Cyrtonops, it falls naturally enough into the Disteniince 

 and in some respects agrees even better than Cyrtonops with the 

 general characters of that subfamily.

Of a glossy chestnut-brown colour, somewhat darker above
