$ . Clypens porrect, the apex transverse, the antennal carina 

 hrofxd beneath, ruuning into a sharp edge at top ; vertex of the 

 head closely punctured ; the front, thorax, and abdomen more 

 sparsely punctured ; the enclosed triangular space at the base of 

 the median segment smooth and shining ; abdomen about as long 

 as head and thorax united. Black ; the base of the mandibles, the 

 clypeus and face to a little above the base of the antennae, the 

 antennal carina, the cheeks behind the eyes, the pronotum, 

 scutellum, postscutellum, a large oval spot on each side of the 

 median segment, the mesopleurae, and large lunate spots on both 

 sides of the apical margins of abdominal segments 1-5, bright 

 yellow ; the legs yellow, marked with ferruginous ; the apical 

 segment of the abdomen ferruginous; the ilagellum of the antennae

 not so deep or close as on the head above ; clypeus broad, flat,

 antenna hollow and smooth ; median segment with the enclosed 

 space at base small, triangular, smooth, medially furrowed ; the 

 apex of the enclosure and the furrow, which is continued down to
