KEVISION OF ELEODIINI BLAISDELL, 445 



length of the second, the third about equal to the fourth, tlie latter 

 one-third of its length shorter than the second. 



The abdominal salient is one-fifth of its own width greater than 

 that of the metacoxal process. 



The tibial grooves of the femora are distinctly concave, with Avell 

 defined asperate or subserrulate margins. The margins of the ante- 

 rior and middle grooves converge gradually to the femoral bases; 

 those of the metafemora become evanescent at about the middle, 

 thence to base the femoral surfaces are simply more or less flattened. 



The grooves of the i^rofemoi'a have their anterior margins more or 

 less dentately laminate at about the outer fifth. 



The external surfaces of the protibia? are subcarinate; those of the 

 meso- and metatibia» are rounded and scabrously sculptured, not in 

 the least carinate. The protiliise are slightly compressed; the others 

 are subcylindrical in transverse section. The tarsal grooves are rudi- 

 mentary on all of the tibia^, but most marked on the protibise; all are 

 roughly sculptured. On the protibia? the more or less evident carina 

 passes to the external margin of the groove, while the internal margin 

 is quite distinctly serrulate. 



The anterior surfaces of the protibise are much less roughly sculp- 

 tured than the posterior surfaces. 



The articular cavities of the protibise are partly closed, those of the 

 mesotibia^ almost closed, and those of the metatibia^ entirely so. 



Tarsi apparently variable in stoutness and independent of sex. 



The protarsi about one-third of their length shorter than a meso- 

 tarsus. Joints 1 to 4, inclusive, are short and subequal in length ; the 

 first is ai^parently slightl}' longer and slightly produced beneath. 



The mesotarsi are about one- fourth of their length shorter than a 

 metatarsus. Joints 2 to 4, inclusive, are subequal in length and 

 slightly longer than wide ; the first is slightly longer and stouter. 



The metatarsi are about two-fifths of their length longer than a 

 protarsus and scarcely two-thirds as long as the metatibia. Joint 

 one is distinctly shorter than the next two taken together; the second 

 and third joints are subequal in length, and together about equal to 

 the fourth.

Elongate oval to ovate, more or less shining, elytra strongly de- 

 pressed. 



Head less than twice as wide as long, quite flat between the more or 

 less prominent sides of the frons, finely and sparsely punctate, punc- 

 tures denser laterally and on the epistoma. Aiitennre rather long, 

 reaching a little beyond the prothoracic base, moderate in stoutness,
