REVISION OF ELEODIINI BLAISDELL, 325 



The metasterniim laterally l^etween the coxa? is as long as the width 

 of a mesotibia at the apex. 



The intercoxal process of the abdomen is slightly transverse and 

 about a third of its width broader than the metasternal salient. 



The jDOst-coxal portion of the first abdominal segment is equal in 

 length to the process and also to that of the third; the second is 

 about twice as long as the fourth. 



The protarsi are about a fourth of their length shorter than a meso- 

 tarsus; the mesotarsi are about a fifth of their length shorter than a 

 metatarsus; the metatarsi are about three-eighths of their length 

 shorter than a metatibia. 



ELEODES TENEBROSA Horn. 



Elcodcs tcnrhrosa Horn, Trans. Amer. I'lill. Soc, XIV, 1S70, p. 316. 



Oblong-oval, about tw^o and a third times longer than wide; elytral 

 sculpturing consisting of very small shining tubercles arising from a 

 ver}^ opaque base. 



Head twice as wnde as long, feebly convex, moderately impressed 

 laterally and frequently along the frontal suture, which is usually 

 not evident, not coarsely and more or less densely punctate, punctures 

 distinctly crowded laterally and on epistoma. Ante'niKV moderate in 

 length, slightly robust, outer four joints very feebly compressed and 

 just noticeably wider, third joint equal to the next two taken together, 

 fourth just the least longer than the fifth, the latter, sixth, and 

 seventh subequal in length, eighth about as wide as long and subtri- 

 angular, ninth subtrapezoidal, tenth suborbiculo-trapezoidal, eleventh 

 frequently slightly smaller and short-ovate. 



Pronofinn transversely oval, widest at the middle, a third to a half 

 wider than long; disc moderately and quite evenly convex, rather 

 coarsely and densely punctate, granulate at the sides; apex slightly 

 emarginate, and more or less obsoletely margined; sides evenly and 

 strongly arcuate from apex to the basal twelfth, then rather quickly 

 sinuate and nearly straight and parallel to basal angles, more rarely 

 evenly arcuate from angle to angle, marginal bead moderate, feebly 

 reflexed and entire ; base subtruncate in circular arc and finely mar- 

 gined, slightly wider than the apex, and not quite equal to the length; 

 apical angles obtuse and more or less narrowdy rounded ; basal angles 

 slightly prominent and quite rectangular, sometimes subobtuse. 



Propleurm smooth and opaque, sparsely and quite evenly granulate, 

 acetabular convexities frequently rugulose. 



Elytra oblong oval, about a half longer than wide, scarcely at all 

 wider than the prothorax, widest at the middle; hase not emarginate; 

 humeri quite broadly rounded, angle sometimes obtusely indicated; 

 sides evenly and not strongly arcuate, frequently subparallel, apex ob-
