Head coarsely and irregularly strigose between the eyes, im- 

 pressed in the middle with a deep fovea ; antennae strongly pec- 

 tinated, pale flavo-fulvous, basal joint short, thickened, second 

 very short, transverse, third slightly longer than the second, 

 moniliform ; anterior edge of epistome concave. Thorax nearly 

 three times as broad as long, sides rounded at the base, with the 

 hinder angles obsolete, thence obliquely rounded and converg- 

 ing to the apex ; basal margin slightly sinuate on either side, the 

 medial lobe scarcely produced, very obtuse ; upper surface mode- 

 rately convex, shining, impunctate. Scutellum trigonate, its apex 

 obtuse. Elytra not broader at their base than the thorax, sides 

 broadly dilated, apex obtusely rounded ; above convex, smooth 

 and shining, impunctate ; each elytron marked with four large 

 black patches, which cover nearly half the surface ; the first, trans- 

 versely ovate, is placed immediately below the basal margin, the 

 second, transverse, is attached to the middle of the suture, the 

 third, parallel with the second, rotundate, is placed just within the 

 lateral margin, and the fourth, subrotimdate, is situated a short 

 distance from the apex of the elytron. Body beneath clothed 

 with fine sericeous pubescence. A patch on either side of each 

 of the three basal, together with the disc of the fourth and fifth 

 segments of the abdomen, black ; apical segment impressed with 

 fovea ; unguiculi nigro-piceous.
