THE CLICK BEETLES. 711 



extending two-thirds from base to apex and a subobsolete fovea on each 

 side slightly in front of middle. Elytra distinctly striate; intervals flat, 

 densely but not rugosely punctate. Length 6 mm. 



Posey County ; rare. May 27. Occurs from Canada to Georgia. 



1343 ( ). Nematodes collabis Bonv., Monog. Eucn., 1875, 663. 



Elongate, subcylindrical, moderately robust. Piceous, feebly shining; 

 legs paler. Antennae slightly more than one-third the length of body; sec- 

 ond and fourth joints subequal, third slightly longer, double the length of 

 fifth ; sixth to eleventh equal, slightly longer than third. Thorax and ely- 

 tra nearly as in penelrans. the former with median line more deeply im- 

 pressed and visible nearly to apex, the fovea eacli side deep, distinct; sur- 

 face more coarsely punctate. Length 9 mm. 



Posey County; rare. May 1. This species was named for me 

 by Chas. Dury, who has taken nine of them near Cincinnati. It 

 was not included in Horn's Monograph of the Subfamily and was 

 described from Brazil, South America, by Bonvouloiri, who also 

 gave "La., N. A.," as a doubtful locality. Mr. Dury identified it 

 from a translation of the original description and his identification 

 was afterwards verified by comparison with the type. 



X. HYPOC(Ebus Bsch. 1836. (Gr., "beneath -h hollow.") 



Small oblong species having the antennas filiform ; elytra striate ; 

 first joint of hind tarsi as long as the next three, the fourth joint 

 not dilated or lobed beneath. One of the two known species was 

 described from Indiana and the other probably occurs. 



1344 (4056). HypoccELUs pbontosxjs Say, Trans. Amer. Phil. Soc., VI, 

 1836, 187; ibid. II, 625. 

 Oblong, slightly attenuate behind. Piceous black, antennse and legs 

 reddish-brown. Antennse less than half the length of body, second joint 

 shorter than fourth, third longer, fourth to tenth very gradually longer 

 and slightly broader, eleventh oval, acute at tip, very little longer than 

 tenth. Front of head with a distinct transverse ridge, clypeus concave. 

 Thorax a little wider than long, median line distinctly impressed its en- 

 tire length, surface very densely and rugosely punctate. Elytra distinctly 

 striate, intervals flat, punctured as the thorax. Length 4.5-5.5 mm. 



Say's types came from near New Harmony, Posey County. 

 Dury has taken it and also the other species, termiiialis Lee, near 

 Cincinnati. The lattei' is distinguished by having the terminal joint 

 of antennse longer than the preceding, the front with a fine longi- 

 tudinal carina, clypeus flat, median thoracic line less impressed. 

 Both species occur on dead hickory.
