22 (82a). Cychrus 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 



23 (86). Cychrus elevatus Fab., Mant, I, 198. 

 Oval, robust. Violaceous or cupreous. Antennae 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. 

 First 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. flammeus Hald., which "differs from the true 

 elevatus by being broader and flatter." 



24 (86a). Cychrus unicolor 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. It eras: the name unicolor, however, has priority. It is un- 

 doubtedly distinct from elevatus.

Cychrus andrewsii germari Chaud., Bull. 

 Mosc, II, 1861, 495. 

 Oval, rather slender. Violaceous above, black be- 

 neath. Thorax longer than wide, subcordate, hind 

 angles obtuse; disk almost smooth, punctate along 

 the sides, margins narrow, slightly reflexed. First 

 joint of front tarsi of male as in elevatus. Length 

 19-22 mm. (Fig. 30.) 



A species of southern range, found in small 

 numbers near Charlestown Landing, Clark Coun- 

 ty; also one specimen from Brown County. 

 May 21-October 1. This is the form often called
