 stripe running entirely around the elytra, except the base: the 

 thorax, the stripe and the sutural edge covered with thick fine 

 golden pubescence, hind tibiae and tarsi rufous, antennae slightly 

 incrassate after the fifth joint, reaching the middle of the elytra, 

 black with joints ten to eleven rufotestaceous. 



T3-pe. — Cochabamba, Bolivia. (Germ.) Length 6.5 mm. 



Clypeus witli a strong carina or ridge on cither side, joining in a point at 

 the base of the antennae and running into a short deej) longitudinal fovea, 

 the sides of which make two short prominent obliciue ridges or frontal tubercles 

 (parallel with the eye), vertex and neck smooth, finely punctulate, the eyes are
