Baptolinus Pilicornis , Payk. Till lately this species has been known in our literature as B. macrocephalus , Nord. It has a very wide distribution across the northern part of the continent, from Alaska to New Hampshire, and through the Alleghanies as for south as southern Pennsylvania, and probably much further. In Europe it ascends to 68°, and is spread over all Siberia to the Amur. It does not seem to be abundant anywhere. It is very variable in colour, and to some extent in the fineness or coarseness of the general punctuation. I took two examples here recently under the bark of a mosscovered decaying oak, and several a few days afterward on the mountains, in the same situation. All these are black and shining, with the mouth parts, antennæ and legs pale, corresponding to the description of Paykull's type. Four examples from Vermont have the mouth parts and the antennæ rufous, and the elyta, rufous, grading imperceptibly to rufo-piceous at the apex and sides.
