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.) Throughout the State.

Scaphidium quadeiguttatum ohliteeatum Lee, Proc. Phil. Acad. Nat. Sci., I860, 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 distinguish this form from qiiadrignttntvm. In my collection are several specimens taken in Vigo County, which have the elytra whoUy devoid of discal 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 oMife
