THE GROUND BEETLES. 43. Fig. 29. (After Leng.) Natural size. 22 (S2a). Cychkus lecontei Dej., Spec. II, 1826, 15. Oval, rather robust; color of the preceding. Basal impressions of thorax broad, with numerous punctures. Elytra deeply striate with closely placed punctures, the intervals interrupted from the middle to apex, thus forming elongate tubercles. Length 12-14 mm. Throughout the State; frequent. April 20-November 5. In the north it occurs beneath sphagnum mosses and about the borders of lakes and tamarack marshes, while in the southern counties it is found in lowland woods. C. canadensis Chaud. has been taken by Dury near Cincinnati, and doubtless occurs sparingly in southern Indiana. (8G). Ctchel's Fab., Mant, I, 198. Oval, robust. Violaceous or cupreous. Antennse slen- der, three-fourths the length of body, first joint longer than third. Thorax with hind angles prolonged over the elytra, the latter with humeral margins much reflexed. IMrst joint of front tarsi of male spongy pubescent over one-half its lower surface. Length 18-19 mm. (Fig. 29.) Fulton County; rare; one specimen from near DeLong. July 30. Two were in the Stein collec- tion from Indiana, but without definite locality. Our form, accord- ing to Leng, is var. flamviem Hald., which "differs from the true elevatus by being broader and flatter.'' 24 (86a). Cycheus unicoloe Oliv., Ent, III, 1795, 47. Resembles elevatus but much larger and more robust. Elytra with a slight emargination or sinuation a little behind the middle, which is not present in elevatus. Length 26-28 mm. Monroe, Lawrence, Knox, Crawford and Harrison counties; one or two specimens from each. Occurs beneath stones in deep ra- vines. May 3-November 14. This is the form often called elevatus var. heros; the name unicolor, however,
