THE CLICK BEETLES. 



753 



tennae reaching basal third of elytra in male, third joint one-halt' longer 

 than second, the two together slightly shorter than fourth. Thorax a little 

 longer than wide, sides nearly straight, disk rather sparsely and finely punc- 

 tate. Elytra very little or not at all narrowed from base to apex, striae 

 feebly impressed, rather finely punctate ; intervals finely, sparsely and some- 

 what roughly punctate. Length 10.7-12 mm. 



Lake County; rare. June 7- July 11. The slender, parallel 

 form, strongly concave clypeus and straight sides of thorax easily 

 distinguish this species. 



1424 (4327). Melanotus verberans Lee, Trans. Amer. Phil. Soc, X, 1853, 



478. 



Elongate, subdepressed. Dark reddish or fuscous-brown, sparsely clothed 

 with grayish pubescence; antennae and legs smoky reddish-brown. Third 

 joint of antennae twice the length of second, one-third shorter than fourth. 

 Thorax about as wide as long; sides nearly straight on basal two-thirds, 

 thence distinctly rounded to apex; finely and sparsely punctured on disk, 

 more densely and coarsely on sides; hind angles sometimes with a faint 

 inner carina. Elytra feebly attenuate from base to apex, punctures of striae 

 slightly impressed; intervals subconvex, finely and very sparsely punctu- 

 late. Length 10-11.5 mm. 



Orang'e and Knox counties; scarce. June 1-June 6. Resem- 

 bles communis, but the punctures of thorax much finer on disk and 

 without trace of median impressed line. 



1425 (4314). Melanotus angustatus Erichs., Germ. Zeitschr., Ill, 113. 

 Elongate, slender. Pale reddish-brow, sparsely pubescent with pale 



yellowish hairs. Clypeus feebly convex, coarsely and closely punctate, its 

 front obtusely rounded. Third joint of antennae double the length of sec- 

 ond, one-third shorter than fourth. Thorax a little wider than long, sides 

 straight from hind angles to middle, thence strongly rounded to apex ; disk 

 rather sparsely and finely punctate, more closely on sides, the carina? of 

 hind angles close to" and parallel with margins. Elytra finely striate-punc- 

 tate; intervals very minutely punctate. Length 9 mm. 



Steuben and Fulton counties ; rare. May 6-June 16. A mem- 

 ber of the Alleghanian fauna.

390. 



Elongate, rather robust. Reddish-brown, sparsely clothed with short 

 pubescence. Third joint of antennae twice as long as second, but little 

 shorter than fourth. Thorax convex, distinctly longer than wide, sides 

 rounded in front of middle ; punctures tine and very dense on basal half, 

 gradually becoming sparse and coarse near front margin ; disk feebly chan- 

 neled behind the middle. Elytra 1 striae with rather distant moderately im- 

 pressed punctures. Length 13-14 mm. 



Vermillion, Lawrence, Clark and Spencer counties ; scarce. May
