Common. The space between tha white triangular 
spot and the oblique fascia of the elytra is not wider than 
the white belt ; it is sometimes of a darker hue than the 
rest of the elytra, and looks then like a distinct dark 
fascia.

6r. Clymeni valde affinis, differt colore ferrugineo 
obscuriori et spatio inter fascias elytrorum multo latiori ; 
ferrugineum, tibiis tarsisque obscurioribus, sparsim hirsu- 
tum, politum ; elytris apud medium fasciis duabus obli-

The two white marks of the elytra constitute two 
fascia, the first not being triangular. The distance be- 
tween the two is twice the width of the posterior fascia.
