 front and occiput smooth, median depression distinct, interocular 

 space about half width of head. Pronotum twice as wide as long, 

 convex, with y^vy narrow explanate margin, narrowed straightly 

 anteriorly; distinctly but sparsely punctate. Scutellum rounded, 

 shining, black. Elytra elongate-oval, moderately convex with very 

 narrow margin and with rounded umbone prominences producing 

 deep basal sulcus, finely and faintly punctate, sometimes appearing 

 nearly smooth except about base and along suture; entirely dark 

 colored with purplish or greenish luster or piceous. Body beneath

Type locality. — Carolina. 



Distrihution. — Carolina, Georgia, Florida, Louisiana, Mississippi,

This species is not easily distinguishable in all cases from lugens. 

 In general it is more convex and with longer elytra, and the ventral 

 surface has more yellow l)rown on abdomen. There are more distinct 

 prominences and a deeper median depression on front of head, and 

 on the front of the head are two indistinct reddish brown spots. 

 The usual distribution appears to be southern, but in the Museum 

 of Comparative Zoology are two specimens labeled Illinois, and 

 W. S. Blatchley gives Lake County, Ind., as a locality.
