with a strong longitudinal carina, the depressed lateral 

 spaces smooth and shining. Nervulus praefurcal ; second

The sharp bend near the apex of the antennae in this genus 

 seems to be a sexual character, not found in the males. 

 The genus does not seem to be separated from Xylonomus by 

 any other good character.

$ . Antennae sharply elbowed at the base of the twentieth 

 joint, the nineteenth joint with two slender spines at the 

 apex, third joint almost as long as the fourth. Clypeus 

 very short, face and clypeus closely punctured ; front 

 shining, smooth in the middle, without a tubercle, the sides 

 of the front and the vertex finely punctured. Posterior 

 ocelli as far from the eyes as from each other, and twice as 

 far from the posterior margin of the head. Angles of the 

 prouotum produced into minute tubercles ; mesonotum as 

 long as the scutellum, postscutellum, and median segment 

 combined, very finely and closely punctured on the lateral 

 lobes and on the front of the median lobe, the posterior 

 half in the middle broadly, very coarsely, and irregularly 

 reticulate. Scutellum very finely punctured, the basal 

 transverse groove broad and divided .by a low carina. 

 Median segment without a basal area, the areola not 

 separated from the petiolar area, punctured, spiracles 

 elliptical, the spiracular area reticulate. Abdomen rather 

 slender, the three basal segments rugulose, the apical 

 segments closely and minutely punctured ; first tergite 

 about twice as long as the second, with two converging
