REVISION" OF ELEODIINI BLAISDELL. 471 



posteriorly, indicating an approach to laminatum Casey. The 

 females have the elytral disc broadly oval and quite flat. The epi- 

 pleurse are not at all defined from the inflexed sides except at apex, 

 they are glabrous. In these specimens the sexes have the prothoracic 

 margin slightly broader and more decidedly reflexed than the average 

 number of specimens of the typical form {forma typica) ; in fact, 

 some specimens have the margins scarcely at all reflexed. 



These large specimens may be placed as an extreme form in the 

 cabinet, and labeled forma grandis. 



General observations. — Mentum more or less variable and moderate 

 in size. Middle lobe arcuate anteriorly, or subtruncate with the 

 sides straight and converging to apex; surface very feebly concave, 

 rather longitudinally prominent at middle and broadly, feebly con- 

 cave laterally and more or less punctate. 



The prosternum between the coxse is quite suddenly prominent 

 ventrallj^, antero-posteriorly arcuate, frequently more or less grooved. 

 Feebly widened behind the equator of the coxa\ 



The mesosternum is more or less obliquely and arcuately declivous, 

 more or less broadly and feebly concave. 



The abdominal salient subquadrate and scarcely as wide as the 

 third segment is long; post-coxal part of first about equal in length 

 to the second segment, the latter twice as long as the fourth ; third 

 about one-third of its length shorter than the second. 



The abdominal and metasternal processes are subequal in width. 



The metasternum laterally between the coxee is very short and 

 about equal to a mesotibia at base. 



The tibial grooves of the femora are entire, well defined and gla- 

 brous; their margins are subacute and smooth. The profemoral 

 grooves are more or less strongly concave; the margins converge to 

 become contiguous at the femoral base. 



The mesofemora have the grooves scarcely concave; the margins 

 converge to become feebly distant at femoral base. 



The grooves on the metafemora are not concave, quite flat, with 

 margins gradually converging and slightly distant at base. 



The protibite are slightly compressed and carinate externally, the 

 carina is entire, the tarsal groove is immediately behind it and is 

 frequently obsolete, the surface always asperate. 



The mesotibia? are more or less distinctly grooved externally in 

 apical two-thirds ; the surface of the groove is glabrous, with sparsely 

 placed asperate punctures. 



The metatibise are simply flattened externally and asperate. 



Tarsi moderate as usual. 



The protarsi are scarcely one-fourth of their length shorter than a 

 mesotarsus; joints two, three, and four subequal in size and very 

 slightly wider than long and together about equal to the fifth; the
