FAMILY XXXVII. — ELATEKIDJL. 



from Kosciusko County is 4 mm. larger than any others in the col- 

 lection, measuring 18 mm. in length. 



1444 (4385). Athous acanthus Say, Trans. Amer. Phil. Soc, VI, 1836, 



ITS ; ibid. II, 615. 



Differs from the preceding only ii) its smaller size and usually darker 

 color and in having the thorax more convex and more finely punctured. 

 Rarely the thorax is reddish-yellow, with a narrow discal black spot. Length 

 7.5-10 mm. 



Southern half of State, frequent; Kosciusko County, scarce. 

 May 20-June 24. 



1445 (4390). Athous cucullatus Say, Ann. Lyc. Nat. Hist., I, 1825, 264; 



ibid. I, 397 ; II. 613. 



Elongate, slender. Dull reddish or sooty-brown, sparsely pubescent 

 with short, suberect yellowish hairs. Clypeus obtusely rounded and with a 

 large triangular impression. Thorax one-third longer than wide, sides 

 straight, male ; broadly rounded on apical half, female ; disk convex, densely 

 and rather finely punctured ; hind angles obtusely rounded and with a dis- 

 tinct oblique carina. Elytral striae feebly impressed with somewhat distant 

 punctures; intervals subconvex, finely and sparsely punctulate, transversely 

 wrinkled. Length 10.5-11.5 mm. 



Lake, Kosciusko, Putnam and Posey counties ; scarce. May 12- 

 September 30. The species in hand is the one recognized by 

 LeConte as Say 's cucullatus. In the original description Say states 

 that the "second joint of antennae is not much shorter than third," 

 whereas it is not more than one-third the length of third. It is 

 possible that Say meant that the "third joint is not much shorter 

 than fourth." Otherwise LeConte was wrong in his determination, 

 as the comparative length of these antenna! joints seldom varies. 



1446 (4395). Athous scapularis Say, Trans. Amer. Phil. Soc, VI, 1836, 



178 ; ibid. II, 615. 



Elongate, slender, subdepressed. Black, 

 opaque, finely and sparsely pubescent; hind an- 

 gles of thorax and a rather broad humeral 

 lunule on each elytron reddish-yellow; legs pic- 

 eous. Antenme longer than head and thorax, 

 second joint one-third the length of third. Tho- 

 rax longer than wide, sides feebly curved, disk 

 densely and finely punctate ; hind angles short, 

 obtuse, with a distinct but fine carina. Elytral 

 intervals subconvex, densely and roughly trans- 

 versely wrinkled. Length 9.5-10.5 mm. (Fig. 

 288.) 



Kosciusko, Knox, Lawrence, Posey and 

 rig. 288. x 4*. (Original.) Crawford counties ; scarce. May 28-July 

 4. Beaten from vegetation, especially that of oak.
