One specimen, collected at Steilaceom, by Mr. George Gibbs, te whom I dedicate it with much 

 pleasure. The second spot of the elytra is situated about one-third from the apex, and extends 

 from the margin nearly te the suture ; the posterior one is near the apex, it also extends nearly 

 te the suture, but is dilated along the margin.
