 fulvescent ; tlie hind-body with suberect yellow ])ubescence. 



Head large, cpiite as broad as thorax, distinctly bisulcate fioni tlie front 

 to beyond the middle ; irregularly, finely, but quite perceptibly pimctate, 

 longitudinally rugose at the sides ; it bears a few fine inconspiciious flaves-

 from the base to near the apex, the inner pair bent outwardly in front, with 

 aliout 8 basal and a jiair of frontal punctures. Elytra slightly broader than 

 long, curvedly narrowed towards the base ; tliey are impunctate, liut have 

 well-marked sutural stria(\ Hind-body V(>iy elongate, fineiy ])uiictiiied, 

 basal segment largest. 



Legs slender and elongate. Tarsi pentamerous, basal 2 joints of the

 and slender. 



Antennae 11 -articulate, inserted below the .sides a short distance in 

 front of the eyes, 2nd oblong, fully as long as the exposed portion of the
