A color variety of quadrlfinttaium which is Avholly 



shining black above. It is found associated with that 



species and in winter is even more frequent, being found 



especially beneath the bark of old, fungus-covered beech 



logs. (Fig. 174.)

 Acad. Nat. Sci., 1860, 322. 

 The absence of coarse punctures on the disk of elytra and the small 

 size of the elytral spots are the only characters given by LeConte and Casey 

 to distinguisli this form from qnadrlgvitatum. 



In my collection are several specimens taken in Vigo County, 

 which have the elytra wholly devoid of diseal punctures and yet, 

 like piceum, are entirely black. I have not seen the spotted form 

 from the State, but the type of LeConte came from near Evansville, 

 Indiana. In all probability Horn was right in regarding both 

 piceum and oUiteratmn as varieties, * Casey to the contrary not- 

 withstanding.* *
