 mandibles black and basally finely punctate, the apex with only one 

 rounded tooth. Antennae slender, densely and obsoletely black-pilose, 

 with the scape testaceous beneath ; a broad band beyond the centre 

 ;and extending to the apices, except their last joint, white. Meso-

 metanotum with its basal half 

 shagreened and apical trans-stri- 

 gose, its basal areae coalescent,

 straight ; the lateral carinae evenly 

 curved on the inner side of the 

 spiracles, with the areas on their 

 inner side crenulate ; metapleurse

 colorous with coxae except basally above and centrally beneath,
