 reflexed, their edges crenulate; median carina? well elevated, divergent 

 on basal half to surround the median polished spot; remaining carina? 

 indistinct. Scutellum broadly triangular, as long as pronotum, sides 

 elevated; disk with basal transverse granulate carina, beyond which

Vigo Co., Ind., March 28 ; a single male taken from beneath 

 bark of an oak log. Say's types were from this State. Of it 

 he says : "Resembles quadrilineatus but the polished thoracic 

 spots and the much more prominent and rounded humerus, not 

 to mention its coloring, readily distinguish it." As his types 

 were destroyed it was, on account of its scarcity, for a long 

 time unrecognized. Bergroth (1892, 332, 334) mentioned a 

 specimen from Pennsylvania, and pointed out the differences 

 between it and both duseei and robustus. Osborn (1903a, 22) 

 recorded three specimens taken by Dury at Cincinnati, Ohio. 

 It is known at present only from the states mentioned and from 



Maryland, Virginia and the Dis- 

 trict of Columbia.
