pale testaceous ; elytra with a narrow, slightly recurved, elevated, 

 median fascia pale yellowish, apical half of elytra blue black. Head 

 including the feebly prominent eyes not wider than the thorax at apex, 

 moderately clothed with whitish pubescence, rather finely very densely 

 punctate. Thorax longer than broad, much narrower at base than at 

 apex, apical margin arcuate, sides broadly rounded to behind the mid- 

 dle, thence gradually convergent to base, less densely but a little more 

 coarsely punctured than the head, clothed with short, recumbent, gray- 

 ish pubescence, and in apical half with long erect black pilosity which

is dense each side of middle, forming a large indefinitely limited 

 rounded spot. Elytra broader at base than the thorax at widest part, 

 sides parallel in basal half, behind this arcuately broadened then nar- 

 rowed to the conjointly rounded apices, humeri moderately prominent, 

 each elytron strongly tuberculate at base midway between scutellum 

 and humerus, the tubercles clothed with erect black pilosity, basal 

 half of elytra rufous, clothed with sparse black pilosity, finely densely 

 punctate, apical half blue black, densely clothed with short grey pu- 

 bescence with some longer erect black hairs intermixed, as densely but 

 more coarsely punctate than basal half, a narrow, slightly elevated 

 somewhat recurved, pale yellow median fascia attains the flanks but not 

 the suture. Body beneath and abdomen sparsely, finely punctate, clothed 

 with sparse whitish pubescence. Legs moderately clothed with whitish 

 hairs. Length 5 mm.
