1155 (3507). HiSTEE mmacllatus Linn., Syst Nat, XI, 567. 



Obloug-ovate, (.-onvex. Elytra black, with tUe outer diagonal lialf 

 orange red. Thorax with one fine marginal stria, abbreviated at tip; disk 

 minutely punctulate and with a broad shallow impression on each side near 

 the front angles. Elytra with five entire strise, the sutural extending in 

 front of the middle ; the subhumeral absent. Front tibite with three teeth ; 

 lupsfislernum truncate. length 4.5 mm. 



Vigo f'Onnt\'; rare. April 13. 



1150 (3505). IIisTER SEDECiMSTRiATUs Say, .lourn. Phil. Acad. Nat. Sci., 

 V, 1825. 36; ibid. II, 263. 

 Rounded-oval, convex. Thorax with inner marginal stria entire, outer 

 wholly absent. Elytra with five entire dorsal striae, the fifth arching at 

 base and joining the sutural, and with two subhumerals, the outer entire, 

 the inner on apical half only. Front tibiae with three teeth, the apical one 

 finely bifid. Length 4^5 mm. 



Southern half of State; frequent. J lay 2-September 10. A 

 prettily and well marked species, common locally beneath carrion 

 and in excrement. 



*]1."7 (3507). IIisTEK AMERicANUs Tayk., Monograph Hist., 1811, 31. 



Rounded-oval, moderately convex. Thorax with inner stria entire, the 

 outer varying from a mere arc at front angle to nearly entire. Elytra with 

 five entire striiE, the fifth curved at base and often joining the sutural ; sub- 

 humeral absent. Upper surface smooth. Front tibiaa with three teeth, the 

 apical one prominent and finely bifid. Length 3-i mm. 



Throughout the State; one of the most common of the family. 

 Hibernates. January 6-October 9. Occurs usually beneath logs or 

 liark in Ioav moist woods. Horn .says that the fifth dorsal very 

 rarely joins the sutural but in one-third of the 2;T or more specimens 

 at hand the two are united, while in our specimen they unite on one 

 side and not on the other. 



1158 (3508). HiSTEK peeplexus Lee, New Spec. N. Amer. Col., I, 1863, 61. 

 Closely allied to amcricanus but larger, more oblong and distinctly but 

 sparsely and finely punctured. Elytral strise more strongly impressed and 

 punctured, the fifth joining the sutural. Length 4-5 mm. 



Lake, Laporte. Kosciusko, Marion, Putnam and Posey counties; 

 scarce. April 18— June 9. Occurs in same localities as amcri- 

 canus and, as Horn sugge-sts. it will probably prove only a better 

 developed geographical race of that species. In one specimen at 

 hand, with surface distinctly ptinetnred, the elytral stria? are not 

 punctured and the fifth does not join the sutural. In another the 

 outer thoracic stria is very fine and entire.
