Beetles. 402 FAMILY XIII. SCAPHIDIID^aO. 6b. Elytra black without spots. 042!i. var. piceum. iia. Elytra without coai-se discal punctures, each usually with two marginal spots of pale yellow.

Black, strongly shining; elytra with spots as mentioned in key. Thorax with a bisinuate row of coarse punctures near the base. Elytra with a row of similar punctures on inner half of base and two to four short rows before the middle and nearer the suture than the sides. Length 3.8^.5 mm. Frequent throughout the State.

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
