Typ. in coll. mea. 



Large species; head black, finely punctured, clothed with fine black 

 hairs which are fewer on the vertex; labrum emarginate, the margin 

 provided with a thick fringe of coarse testaceous hairs, its basal third 

 smooth, the apical two-thirds very closely, finely and regularly punc- 

 tured; eyes slightly reniform; antennoe black, with a tuft of coarse 

 black hairs on the anterior surface of the basal joint and a few scattered 

 black hairs on the next three joints; maxillary palpi large with apical 

 joint inflated and squarely truncate, both maxillary and labial palpi 

 with long black hairs on them ; thorax with punctuation and pubescence 

 like that of head, posterior margin elevated, two feeble impressions, 

 one just in front of the posterior margin, and the other just in front of 

 the posterior third of the thorax, both in the median fine; scutellum 

 small, triangular with the posterior angle truncate; elytra black, with 

 a large juxta-scutellar straw-colored spot, not quite reaching the 

 sutural margin, on each elytron; nearly opposite to this, but rather 

 more in front, a smaller spot on the humeral margin; two wide, wavy 

 bands of the same color dividing the elytra into three nearly equal 

 parts, but placed nearer together than from the basal or apical borders 

 of the elytra; legs black, densely clothed with short black hairs and 

 some longer ones, the front legs very closely covered on their internal 

 surface with short pale hairs and in the males provided with very long
