[Differs from ohsoletns by having on each elytron three raised 

 lines, on which are rows of black points ; by having only two fascipe, 

 the anterior of which is one-third behind the base and extends on 

 the sides to base ; and by the much finer, closer punctuation.] " Ham.'

[This large species has the aiitennre near three and one-half times 

 longer than the body, S , and about twice as long, 9 ; in addition 

 to the three undulated fascia) of the elytra there is an antebasal

[This s})ecies is wider and mure de})ressed than the preceding and 

 with a different facies ; the antennte. S and 9 , are of the same 

 length as in the preceding, but in that the distal end of the fifth 

 joint is nodose-like from some short l)ristles, while in this the distal 

 end of the third and fourth joints are nodose from enlargement; the 

 surface color is lutcous-white, the pubescence grayi.sh white and ex- 

 ceedingly dense and short; there are on the elytra each .side four 

 penicillate elevated lines the inner two of which ai-e united before 

 a])ex, where they are ornamented with an arrowhead-shaped velvety
