As these trees grow indigen- ously only in the southern third of the State, it is probable that the beetle will be found to be confined to that area. Both it and canali- culatus often have a small transverse hoary white spot formed of exuded matter near the margin and just behind the middle of the elytra. Casinn<<v is shorter and has the upper surface more dis- tinctly pubescent with short erect yellowish hairs than in either the preceding or the next species. 1864 (5932). Ckemastochilus haekisii Kirby, Zool. Jourii., Ill, 152. Elongate-oblong. Piceous, rather strongly shining. Mentum plate deeply concave, margins reflexed, more strongly at the sides and behind, its hind margin broadly and deeply notched. Thorax more than one-half wider than long, sides feebly curved; front angles short, obtuse, limited within by a deep impression and behind l)y a finely impressed line: hind angles some- what triangular, smooth, separated from the disk by a rather deep impres- sion ; disk very sparsely and irregularly punctured and with distinct patches of stiff hairs near the hind angles. Elytra very coarsely, deeply and densely punctured. Length 10-11 mm. Lake, Starke and Vigo counties; scarce. April ^l-October 6. Occurs usually in nests of large reddish ant.s in sandy localities. Readily known by its more shining surface, more coarsely and roughly sculptured elytra and larger tufts of hairs near hind angles of thorax. XXXIX. OsMODERMA Lep. 1825. (Gr., "odor-f skin.") Large, broad, dark brown species, having the thorax distinctly narrower than elytra; and rounded on the sides; last spiracle
