Thorax above shining, except in front. Scutellum rather large, 

 broader than long, yellow, a little fuscous in the middle, truncate at 

 the apex. Elytra very long-, Buhparallel, the basal third ochraceous ; 

 each elytron with three distind cost®, besides the three subscutellar 

 costse, which are distinct ; the interstices with two lines of trans- 

 verse punctures, the lines of punctures divided by a fine costa. 



Thorax relatively broader than in the following species (ancep$), 

 and the punctures of the elytra are much more regular and defined, 

 and the intermediate costa?, although fine, are distinct.

Antennae very long and compressed. Thorax small, longer than 

 broad, shining, except in front. Scutellum fuscous, concave, sub- 

 quadrate, scarcely emarginate at the apex (nearly straight), the 

 angles blunt. Elytra very long, dull black, with the basal fifth 

 yellow ; the three costae on each elytron are well marked, and there 

 is a short distinct costa near the scutellum; the usual transverse 

 rugulae of the interspaces are irregular and much broken, for the 

 most part only appearing like granules ; there are no intermediate 

 costae visible.
