ford sinks concinna, affinis and minuta as synonyms of this species 

 but with our present knowledge of the life history of these insects 

 we must keep them distinct. This species is distributed over nearly 

 the whole of the United States and Canada.

 S. pallida Osborn. 



Ohio Nat., v, 375, 1905. 



Here the elytra are marked with a brown vitta from near the 

 base to a fuscous mark at the apex of the clavus where it is 

 deflected to the stigma then back to the inner apical angle and again 

 along the apical margin. This species has the broad short vertex of 

 concinna and somewhat the same elytral markings. It has been 

 recorded from New York to Florida and should be found in 

 Connecticut. 



Liburniella Crawford. 



This genus has the narrow front of Stenocranus, the elytral 

 markings nearly of Stobaera, while the pronotal carinae are those 

 of Liburnia. 

 L. ornata (Stal). (Fig. 1.) 



Berl. Ent. Zeit, vi, 315, 1862. 



Easily distinguished by the narrow white dorsal vitta bordered 

 on either side by a black line, the black front with white carinae, 

 and the broad fuscous vitta on the elytra from the stigma to the 

 inner apical angle and back to the outer apical angle ; there is also 

 a brown cloud on the base of the corium. It is a very pretty 

 species and is found throughout the United States and Canada.

Liburnia Stal. 



This is a large and difficult genus that is badly in need of 

 revision.
