individuals; frons with two brown markings near the margin of the 

 vertex and from four to six brownish arcs on the middle, length five 

 times as much as the width next the clypeus and two and a half times as 

 long as the latter, which is strong, well rounded at the tip, where it is a 

 little wider than at the base; clypeus about twice as long as its width; 

 lorffi not quite as wide as the clypeus, gense white, broad. Brown spots 

 on the face between the frontal sutures and the eyes, just beneath the 

 insertion of the antennas. Pronotum irregularly marked transversely 

 with wavy brown; almost twice as long as the vertex, flat on the middle 

 but slightly convex at the sides; lateral margins short; width of pro- 

 notum equal to twice its length; sternum jet black. Scutellum dirty 

 brown with two blackish markings at the basal angles, a rectangular 

 brown marking on the middle and extending to the apex; indistinct 

 brown spots on the middle and anterior half; length about equaling that 

 of the pronotum. Elytra whitish blue, with a distinct brown pattern; 

 claval area rather long, leaving a small apical area ; outer borders white 

 or with few brown marks. Genitalia male: Last ventral segment 

 brownish, a little longer than the penultimate; valve almost as long as 

 the ultimate segment, plates long, slender and sharp, much longer than 

 the pygofers and about three times as long as the last ventral segment; 

 tips very pointed. Female: Last ventral segment whitish, about four 

 times as long as the preceding ; posterior margin inwardly and angularly 

 rounded, then produced on the middle, the production being pronounced; 

 slightly convex on the top; pygofers brownish, strong, almost three 

 times as long as the last ventral segment and more than twice as long 

 as their width at base; rather widely separated; ovipositor long and 

 broad, longer than the pygofers, sharp at the tip.
