The profemoi'a (male) are clavate, gradually tumid externally 

 and subcylindrical in section; less so in the female and frequently 

 somewhat compressed. The tibial grooves are more or less Avell 

 defined by subcariniform margins Avhich become contiguous and 

 evanescent at basal fourth; the floors of the grooves are usually con- 

 cave, glabrous or sometimes minutely subasperate. 



In both sexes the mesofemora are subtumid at middle, with the 

 grooves rather narrow and limited by subasperulate margins, which 

 are more or less evanescent before becoming contiguous at basal 

 third. 



The sexes have the metafemora usually just noticeably widening 

 from base to apex; grooves as on the mesofemora. 



The protibia.' are frequently subarcuate. feebly compressed. All 

 the tibio' are without tarsal grooves and more or less muricate; the 

 articular cavities are closed. 



The tarsi are moderate in length and stoutness. The protarsi are 

 about a half of their length shorter than a mesotarsus. Joints tAvo, 

 three, and four are subequal, and combined subequal to the fifth; the 

 first is longer than wide. 



, The mesotarsi are subequal to (male) or a seventh of their length 

 shorter than (female) a metatarsus. Joints one and five subequal in 

 length, either one is subecjHal to the combined lengths of the third 

 and fourth; joints two to four subequal in width and length, or just 

 feebh' diminishing in length in the order named. 



The metatarsi are about a third of their length shorter than a meta- 

 tibia. The third joint is slighth' shorter than the second, both com- 

 bined about equal in length to the fourth; first joint equal to the 

 combined lengths of joints two, three, and four of a mesotarsus.

Form as in carhonaii((^ smooth and more or less feebly shining, 

 sides of the pronotum apparently evenlj^ arcuate; elytral punctures 

 usually moderately small. 



Head twice as wide as long, more oi' less moderately convex, some- 

 wdiat coarsely, irreguhirlv, and sparsely punctate, i)unctures slightly 

 denser on the epistoma ; surface usually impressed laterally. An- 

 tcniup moderate in lengtli, reaching to the base of the ]U'othorax, sub- 

 equal in the sexes, outer three joints scarcely conn)ressed or dilated, 

 third joint about e(|ual to tlie next two taken together, tlie fourth 

 very slightly longer than the fifth, the latter, sixth, and seventh sub- 

 equal, eighth subtriangular, and slightly shorter than the seventh, 

 ninth and tenth suborbicular, eleventh subovate. 



Pronotum quadrate, widest at the middle. Avhere it is one-eighth 

 to one-sixth wider than long, sliglitly narrowed before and behind; 

 disc moderately convex, quite strongly and arcuatel}^ declivous along
