EEVISION OF ELEODTINT BLAISDELL. 467 



The tibial grooves of tlie femora are well developed and defined; 

 surface of each plane to concave, glabrous and at times feebh^ rugu- 

 lose; margins well defined and more or less acute, gradually con- 

 vero-ino- to the femoral base in each instance, those of the profemora 

 are slightly arcuate. 



The protibise are slightly compressed and distinctl}^ carinate ex- 

 ternally, carina more or less entire, surface behind it rather narrowly 

 and longitudinall}' grooved, groove more or less asperate. 



Tarsal grooves of the mesotibise rather more or less evident ex- 

 ternally in apical two-thirds, grooves more or less narroAv, sub- 

 glabrous or subasperate. External surfaces of the metatibise are 

 more or less flattened, scarcely grooved and asperate. 



The tarsi are moderate in length and stoutness. 



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

 mesotarsus. The fii-st four joints are subequal in length, the first is 

 slightly longer than wide, the succeeding three feebly wider than 

 long. 



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

 metatarsus. First joint scarcely as long as the next two combined; 

 the second, third, and fourth subequal in length and distinctly 

 longer than wide; fifth a little shorter than the preceding three 

 taken together. 



The metatarsi about three-fifths as long as their tibia^. First 

 joint quite equal to the succeeding two taken together, the fourth 

 just a little longer than the second and third combined, the latter 

 two are equal to each other.

 prothorax rather broadly foliaceous, elytral margins less strongly 

 so, margins distinctly attaining the apex. 



Head small, less than twice as wide as long, nearly plane, broadly 

 and feebly impressed laterally, sides of the f rons rather prominent ; 

 surface very finely, sparsely, and quite indistinctly punctate, each 

 puncture bearing a small, short, and curved seta.

 four joints, which are feebly Avidened; third joint a little shorter 

 than the next two taken together; fourth slightly longer than the 

 fifth : the latter, sixth, and seventh subequal ; eighth slightly shorter
