 less thickly covered with whitish down on the under

 is a small white spot. The elytra are marked with 

 a few deep grooves, which are pretty densely clothed

 rubbed off, and in the bottom of each groove there 

 appear two rows of small impressed points, and a 

 longitudinal ridge between them. Each elytron has 

 five spots of white down, but some of these are often 

 obliterated (as in the example figured). The un- 

 der side of the body and legs are of a more shining 

 black than the other parts, and the thighs are some-
