746 FAMILY XXXY1T. ELATEEID/E. 



equal, together a little shorter than fourth. Thorax subqnadrate, convex, 

 rather sparsely punctate at middle, very coarsely and closely on sides and 

 with a faint median impressed line near base; hind angles strongly and 

 acutely carinate. Klytral strife with creuate punctures; intervals flat, finely 

 and sparsely punctulate. Length 17.5-18 mm. 



Orange and Crawford counties; rare. Jrme 1-Jnne 26. This 

 species may prove to be the female of corticinus. The single type 

 at Cambridge is a female, as are also both of my specimens. 



1408 (4320). MELANOTUS CASTANIPES Fayk., Faun. Suec. Insect.. Ill, 1800. '2-',. 



Elongate, the sides parallel. Very dark reddish-brown, sparsely pubes- 

 cent. Second and third joints of antenna? subequal. together slightly shorter 

 than fourth. Thorax a little longer than wide, distinctly narrower at apex 

 than base, sides feebly but distinctly rounded from base of hind angles to 

 apex; disk coarsely and densely punctured, the median impressed line dis- 

 tinct on basal third; bind angles elongate, acute, divergent, strongly and 

 obliquely carinate. Elytra with sides straight and parallel from base nearly 

 to apex; strife feebly impressed with elongate punctures. Length 18-121 mm. 



Laporte County; rare. May 20. Taken from beneath the baric 

 of pine, and probably occurs only in the northern counties. 



1409 (4312). MELANOTUS IGNOBILIS Melsh., Proc. Phil. Acad. Nat. Sci., II. 



1844, 152. 



Elongate, slender. Piceous or very dark reddish-brown, sparsely pu- 

 bescent. Antenna? elongate, joints broader and more strongly serrate than 

 usual, the third one-fourth longer than second. Thorax subquadrate, slightly 

 longer than wide, a little narrowed in front, sides straight; carime of hind 

 angles continued onto elytra 1 liumeri. Elytra feebly but distinctly narrowed 

 from base to apex, marked with rows of large, round, deep punctures; in- 

 tervals minutely and sparsely punctate. Length 10.5 mm. 



Fountain County; rare. June 16. Described from Pennsyl- 

 vania. The long parallel canine of hind angles, carinate humeri 

 of elytra and broad antennal joints make this an easily distinguished 

 species.

 prostrate grayish hairs. Antenn.-e of male reaching middle of elytra, of 

 female one-fourth shorter; joints 2 and 3 subglobular, the third one-fourth 

 longer than second, together much shorter than fourth. Clypeus concave, 

 coarsely and densely punctate, its front margin feebly angulate at middle. 

 Thorax one-fourth longer than wide, sides straight and diverging from apex 

 to base; disk very sparsely and rather finely punctate at middle, more 

 coarsely and closely on sides. Elytra with rows of coarse, close-set punc- 

 tures; intervals smooth or nearly so. Abdomen coarsely and rather densely 

 punctate. Length 9.5-10 mm.
