REVISION OF ELEODIINI BLAISDELL. 313 



16. Sides of pronotum more strongly arcuate in front of middle, behind narrow- 

 ing rather suddenly and more or less subangulate, or more evenly rounded 

 and less gradually naiTowing behind. 



Elytra coarsely rugoso-punctate cordata. 



Elytra sculptured with distinct tubercles, which vary in size, rounded 

 or submuricate. 



Tubercles distinct, rounded, not noticeably setigerous; legs 



black pimelioides. 



Tubercles more evidently setigerous; legs brown var. brunnipes. 



Sculpturing finer, distinctly pubescent throughout, somewhat like 

 hirsuta, hairs shorter than in that species; legs reddish or 

 brownish caseyi. 



The reader will no doubt appreciate the difficulty of formulating a 

 table that will make it possible to place all specimens, especially in a 

 genus so protean as Eleodes. I desire to impress on the student the 

 importance of first determining the subgenus to Avhich the specimen 

 under consideration actually belongs, then try to determine wdiether 

 it is typical specifically or exhibiting considerable variation. The 

 most important diagnostic tests are those considering the general 

 form, form of thorax with its sculpturing, form and sculpturing of 

 the elytra. Color plays very little part in Eleodes^ although surface 

 luster is often helpful. 



ELEODES TIBIALIS, new species. 



Elongate, oblong-ovate, nearly three times longer than wide, very 

 smooth and shining, strongly depressed. 



Head about twice as wide as long, feebly convex, more or less obso- 

 letely impressed laterally, frontal suture obsoletely indicated, very 

 finely, sparsely, and ii-regularly punctate, punctures just noticeably 



[denser laterally and on the epistoma. Antennm moderate in length 

 and stoutness, outer three joints very feebly compressed, feebly and 

 very gradually dilated, third joint about equal to the next two taken 



[together, fourth slightly longer than the fifth, the latter, sixth, and 



.seventh subequal in length, eighth more or less triangular, ninth and 



|tenth orbicular, eleventh short ovate. 



Pronotvm quadrate, widest at or just a little in front of the middle, 

 about a third wdder than long; disc evenly, very moderately convex, 

 frequently somewhat depressed, more or less declivous at the apical 

 angles, very minutely punctulate, obsolete!}^ so at times, punctules 

 sparse; apex truncate to moderately emarginate, very finely and more 

 or less obsoletely margined; sides quite evenly and not strongly 

 arcuate, slightly less so and at times somewhat straight in the pos- 

 terior third, marginal bead entire and fine; hase truncate, sometimes 

 feebly sinuate at middle, margin fine, a little wider than the apex; 

 apical angles more or less prominent anteriorly, obtusely and nar- 

 rowly rounded ; basal angles obtuse and not in the least rounded.
