REVISION OF ELEODIINI BLAISDELL. 477 



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

 brous, concave on the profemora, less so on the meso- and meta- 

 feniora ; the margins are acute and smooth, gradually converging to 

 the femoral base, where they meet. 



The protibioe are scarcely at all compressed nor carinate exter- 

 nally, simply flattened or feebly concave in apical half, forming a 

 slight tarsal groove, which is moderately asperate. 



The meso- and metatibiaj are very feebly flattened externally in 

 apical half. 



The tibiae appear to be quite variable as to length. In some ex- 

 amples the protibia^ are scarcely more than one-half the length of the 

 metatibia': while in others they are at least three-fifths as long. This 

 seems to be an individual variation observed more or less throughout 

 the tribe Eleodiini. 



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

 mesotarsus. The four basal joints are small, the second, third, and 

 fourth subequal in size and length and about as wide as long; the 

 first is about one-half longer than wide; the fifth about equal to 

 the three preceding joints taken together. 



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

 metatarsus. Joints two, three, and four are subequal in length and 

 slightly longer than wide ; the first is distinctly more than one and 

 a half times longer than wide; the fifth about equal in length to the 

 preceding three combined. 



The metatarsi are about half as long as a metatibia. The first joint 

 is about equal to the fourth; the second and third are subequal. the 

 second apparently just a little longer than the third, and both taken 

 together about equal to the fourth. 



Genus ELEODIMORPH A, new. 



Body rather robust and blapyliform. 



Head not deeply inserted, epistoma distinctly emarginate, sides of 

 the front straight and converging anteriorly and not in the least 

 dilated, frontal suture scarcely evident ; eyes narrow, transverse, and 

 subreniform; antenna^ 11-jointed, outer three joints feebly com- 

 })ressed. Mentum moderate, trilobed, lateral lobes rather small and 

 inflexed, middle lobe trapezoidal, narrowing at base as usual and 

 attached to a short gular peduncle, surface concave. 



Maxillary palpi moderate in length, last joint triangular and mod- 

 erately broad ; third subtriangularly obconical, a little longer than 

 wide and about two-thirds as long as the second, the latter elongate 

 and obconical. 



Lahial palpi small, last joint more pyriform than triangular, con- 

 stricted at base on internal and lateral surfaces.
