black, faintly tinged with violaceous; this colour 

 is very obvious on the lateral edge, and posterior 

 margins ; lateral, a little excurved near the pos- 

 terior angles : elytra deeply striated ; the disk is 

 less distinctly violaceous than the margin, and in 

 a particular light, their colour exhibits a slight 

 greenish tinge; beneath violaceous, and more 

 particularly so on each side: epipleura bright 

 violaceous. 



OBSERVATIONS. 



It seems probable, that this species is not an 

 inhabitant of the northern part of the United 

 States, or if found at all in this region, it is cer- 

 tainly very rare. It is, w^ithout doubt, chiefly 

 limited in its range to the southern and south- 

 vs^estern states, but it is not known to be abundant 

 any where. In my specimen, the second and 

 third interstitial lines of each elytrum, are con- 

 nected near the base by a transverse line, but this 

 is very possibly not a permanent character. It 

 is now figured for the first time.
