 the naked eye they appear smooth, beneath a lens very weak 

 undulating and rather unequal striae are visible. The lateral 

 punctures are the same as those in P. semiviolaceus. The anterior 

 thighs show the same projection below [in 5]-

 are irregularly dispersed in these striae ; on the posterior part of
