The common white spot on the elytra is so densely pubescent 

 that the underlying sculpture is entirely concealed. The spot 

 occupies in its front all the width between the seventh interstices 

 of the two elytra but narrows a little to its apex where it occu- 

 pies the width between the two fifth interstices. Its front margin 

 is a little behind the base of the elytra but in its middle runs for- 

 ward triangularly to the scutellum ; its sides are somewhat zig- 

 zagged, being cut into most conspicuously by a black spot a little 

 behind the middle j its apex (a little in front of the hind decliv- 

 ity) is arcuately and irregularly emarginate and its surface is 

 interrupted by a few very small black spots. The red pubescence 

 near the apex of the elytra is not entirely confined to the fourth 

 interstices but appears as spots on some of the other interstices, 

 and there is also a little white pubescence near the apex. The 

 third and fifth interstices of the elytra are a little more strongly 

 elevated near the base than in the middle of their length. It is 

 (as already noted) very probable that Tropideres musivus, Er., and 

 albuginosus, Er., are congeneric with this insect. Assuming them 

 to be so this insect differs from them specifically, — from musivus, 

 inter alia, by its considerably larger size, by its not having three 

 fascicles of pubescence on its prothorax and by the proportions of 

 its antennal joints, — from albuginosus, inter alia multa, by its 

 antennae not long enough to reach the base of the prothorax.
