REVISION OF ELEODTINI BLAISDELL. 67 



The post-coxal part of the first segment is equal in lengtii to tlie 

 process, equal in length to the second segment in the male, and the 

 third segment in the female. 



In the male the third segment is a third of its length longer than 

 the fourth; in the female the second is twice as long as the fourth. 



The legs are usually quite strongly sculptured. The profemora 

 and the metafemora are as in caihonaria. The mesofemora are usu- 

 ally, gradually and feebly widened from l)ase to apex. 



The protibia' are subcylindrical in transverse section. All the 

 tibiae are Avithout tarsal grooves and the articular cavities are closed. 



The tarsi are moderate in length, comparatively a little stouter 

 than in ohsoleta. 



A protarsus in the male is about a sixth of its length longer than in 

 the female, and subequal in stoutness in the two sexes. 



The relative proportions of the tarsi to each other, and the con- 

 stituent joints of each one to each other is practically the same as in 

 ohsoleta. - 



ELEODES KNAUSII, new species. 



Oblong-ovate to ovate, more or less shining, estriate and moder- 

 ately convex. 



Head twice as wide as long, feebly convex, frontal suture feebly 

 marked, frons A^ery slightly impressed laterally, somewhat coarsely, 

 irregularly and more or less densely punctate, esj^ecially on the epis- 

 toma. Anteniim moderate in length, outer four joints feebly com- 

 pressed, distal three slightly dilated, third about as long as the next 

 two taken together, fourth scarcely longer than the fifth, the latter, 

 sixth and seventh subequal in size and about as wide as long, eighth 

 shorter and apparently a little wider than long, ninth subtriangular 

 and slightly transverse, tenth transversely oval, eleventh ovate. 



Pronotum subquadrate, widest just in advance of the middle when 

 viewed vertically from above, at the middle when viewed obliquely 

 from the side, and about a third wider than long: disc evenly and 

 moderately convex, rather arcuately declivous at the sides and apical 

 angles, quite finely, irregularly and somcAvhat sparsely punctate, 

 punctures slightly denser at the sides; apex more or less feebly 

 emarginate in circular arc. finely and more or less obsoletely beaded ; 

 sides moderately arcuate in anterior three-fourths, thence obliquely 

 convergent to base as viewed vertically from aboA'e. or more strongly 

 arcuate anteriorly, thence convergent and more or less sinuate to 

 base when viewed obliquely from the side, finely beaded ; hnse feebly 

 arcuate, sometimes feebly sinuate at the middle, finely and moi-e or 

 less obsoletely beaded, one-fifth to one-third Avider than the apex; 

 apical angles distinct, not at all prominent anteriorly, sometimes very 

 feebly and narroAvly rounded; basal angles obtuse.
