to be due to an injury: it is very distinct in almost all 

 our specimens ; the minute circular impressions on the disc 

 before the middle, however, are much less constant: in 

 several of my specimens they are wanting, in others they 

 are four in number and irregularly arranged. As to the 

 legs Westwood says: »the posterior margin of the four 

 hind legs is clothed with luteous hairs", but this is not 

 correct: the posterior margin (under side) of the fore- and 

 middle legs (femora) is clothed with luteous hairs , which 

 are much more densely set (feltlike) in the male than in 

 the female. — The middle of the abdomen is flattened in 

 the male, convex in the female, the pygidium transverse 

 in the male, more triangular in the female, and the cal- 

 caria of the hind tibiae are more slender and acute in the 

 male, broader and more obtuse in the female.
