Head with the front slightly reflexed ; eyes divided, with^ the 
small upper lobes placed well forwards on the inner side of the 
antennal tubercles, the lower lobes somewhat rounded. Antennae 
10-jointed, sparsely setose, a little longer than the body in the 
male, shorter in the female ; 1st joint, the longest, slightly curved, 
and gradually thickened towards the apex ; 2nd almost half as 
long as the 3rd, which is barely shorter than the 4th, the following 
joints gradually decreasing in length. Prothorax constricted and 
depressed at the base, arched and slightly widened anteriorly, with 
the front margin of the pronotum farther advanced than the front 
of the prosternum. Elytra sparsely setose, somewhat depressed 
behind the base, slightly widened towards the middle of their 
length, and conjointly rounded behind ; each bearing a very feeble 
and almost obsolete centro-basal tubercle. Legs moderately long, 
with the distal half of each of the femora thickened into a stout 
oval club. Middle tibiae sinuately emarginate on their outer distal 
border. Claws of tarsi divergent. 
This genus, which includes two of the smallest species 
of Longicorns known, is allied to Cyrtinus, Leconte, and 
Myrmolamia, Bates ; in both of which genera the an- 
tennae are 11 -jointed, and each elytron bears a distinct 
centro-basal tubercle.
