 542, 



Oval, convex. Blackish-bronzed, often with a faint 

 greenish tinge ; femora piceous, tibiae and tarsi paler. 

 Thorax subquadrate, narrowed from slightly behind 

 middle to apex; surface smooth; inner basal impres- 

 sion often evident, not punctured, outer one obsolete. 

 Elytra as wide at base as thorax, striae shallow, not 

 punctured ; a single large puncture at junction of sec- 

 ond and sutural striae. Leugth 7-9 mm. (Fig. 65.) 



Fig. 65. X (Original.) 



Throughout the State ; common. Probably hi- 

 bernates. March 12-October 21. The females 



have the upper surface alutaceous. 



*157 (659). Amaea basillaeis Say, Trans. Amer. Phil. Soc. II. 1823, 35; 



Oblong-oval, convex. Blackish-bronzed or purplish-black, shining; legs 

 reddish-brown, the femora darker. Thorax subquadrate, nearly twice as 

 wide as long, narrowed from about the middle to apex; basal impressions 

 double, with numerous distinct punctures, the inner longer than the outer. 

 Elytral striae rather deep, punctured. Length 7-8.5 mm. 



Vigo County: rare. January 13. Taken from beneath mullein 

 leaves. 



158 (661). Amaea cupeeolata Putz., Mem. Liege, I. 1866. 180. 

 Oblong-oval, convex. Bronzed or purplish-black, shining, the females 



finely alutaceous; antennae and legs piceous. Thorax one-half wider thau 

 long, narrowed from about one-third in front of base and rounded to apex ; 

 basal impressions feeble or wanting ; hind angles obtusely rounded, the 

 puncture near them distant from side margin and much nearer the basal. 

 Elytra not wider than thorax, subparallel to behind the middle, the striae 

 not or very finely punctured. Length 6-7 mm. 



Throughout the State: our most common species. March 4- 

 •July 24. Resembles impuncticollis but readily distinguished by the 

 lack of ocellate puncture at base of scutellar stria. 



159 (664). Amaea fai.lax Lee. Ann. Lyc. Nat. Hist. IV, 1848, 362. 



Oval, moderately convex. Blackish-bronzed, shining in males, alu- 

 taceous in females ; under surface and femora black, tibiae and tarsi dark 

 reddish-brown. Thorax nearly twice as wide as long, narrowed from 

 slightly in front of base to apex, basal impressions indistinct, hind angles 

 rectangular. Elytra slightly wider than thorax, striae not punctured ; the 

 ocellate puncture at junction of scutellar and second stria smaller than in 

 impuncticollis. Length 7.5-9.5 mm. 



Lake, Laporte. Marion. Vigo and Posey counties ; scarce. March 

 26-May 28. Distinguished from impitncticollis only by carinate 

 basal joints of antennae and the more broadly rounded tip of pro- 

 sternum.
