This is in all probability a variety of the male of lugubris, the 

 only difference being that the ridge which encloses the subcordi- 

 form space at the base of the metathorax is smooth and shining, 

 whereas it is usually obhquely striated; but every degree of 

 approach to smoothness is to be met with. No example of the 

 female has occurred with the smooth limbus, although many 

 hundreds have been examined.
