FAMILY XXXVII. ELATEEIDJE. 



1457 (4437). Corymbites divaricates Lee. Trans. Ainer. Phil. Soc. X. 



1S53, 446. 



Oblong, robust. Dull sooty-brown or piceous. sparsely and finely pubes- 

 cent. Third joint of antenna? slightly longer than fourth, much longer than 

 second. Thorax of male subquadrate. feebly convex, sides nearly straight, 

 disk coarsely and densely punctate, hind angles strongly diverging; that 

 of female wider than long, strongly convex, sides broadly rounded, a deep 

 impression each side along front margin. Elytra! stria? feebly impressed 

 with rather coarse punctures: intervals of male flat, densely and roughly 

 punctulate; of female subconvex. finely and sparselv punctulate. Length 

 9-12 mm. 



Crawford County: scarce. June 25-Jrme 28. Beaten from 

 foliage of oak. The so-called female is very different in appear- 

 ance from the male. In addition to the distinctions above given, 

 the body is much more robust, dark shining chestnut-brown in color 

 and much less pubescent. It was described as C. crassus Lec. and 

 may yet prove to be a distinct species. The mere fact that two 

 beetles widely different in appearance are sometimes found in com- 

 pany, or even rarely in coitu. does not furnish absolute proof of 

 their identity. 



1458 (446S). Corymbites ^ethiops Herbst., Kafer. X. 1S06. 70. 

 Elongate, broad, subdepressed. Black, shining, finely and very sparsely 



pubescent ; legs and .antenme piceous or dark reddish-brown. Third joint of 

 antenna? twice the length of second, slightly shorter and much narrower 

 than fourth. Thorax a little longer than broad, narrowed in front, sides 

 feebly rounded; disk finely and sparsely punctate on middle, more densely 

 on sides, with a faint median impressed line; hind angles slightly diverging, 

 distinctly cariuate. Elytra with sides parallel to apical third, thence strongly 

 converging to apex ; stria? finely and closely punctate ; intervals subconvex. 

 sparsely and rather coarsely and roughly punctulate. Length 15-23 mm. 



Throughout the State, frequent: more so in the southern coun- 

 ties. May 10-June 26. Occurs usually beneath stones and rubbish 

 on high, dry hills; also on Virginia creeper. Parthenocissus quinquc- 

 folia Michx. Our largest species of the genus. 



1459 (4482). Corymbites hieroglyph rcrs Say. Trans. Amer. Phil. Soc, 



VI. 1S3G. 172 : ibid. IT. 607. 

 Oblong, robust. Head and thorax piceous. bronzed, densely clothed 

 with very fine, silky grayish-yellow pubescence; elytra dull yellow, with an 

 oblique undulated blackish band from the humerus, connected by a narrow 

 sutural stripe with another similar but broader band behind the middle, 

 the latter with a sutural spur nearly to apex : antenna? and legs reddish- 

 brown. Thorax as in 7/ a mat us. the carina? of hind angles indistinct. Ely- 

 tra with punctures of the stria? smaller than in ha mat us. otherwise similar, 

 Length 11-12.5 mm.
