REVISION OF ELEODIINI BLAISDELL. 26S 



about equal in length to the j^ost-coxal part of the first ; the fourth is 

 half as long as the third. 



The abdominal salient and that of the metasternum are subequal 

 in width. 



The metasternum laterally between the coxae is about equal in 

 length to the width of a mesofemur at base. 



The tibial grooves of the femora are strongly developed and de- 

 fined; the margins are more or less cariniform; the floors are gla- 

 brous and more or less concave. The profemoral grooves nearly 

 attain the femoral base, while those of the meso- and metafemora 

 become more or less obsolete at the basal fourth or third, respectively. 



The anterior margin of eacli groove is more or less laminate, and 

 dentately so at about the outer fourth. The femora are distinctly 

 sinuate external to the teeth, and the anterior surface is longitudinally 

 and inwardly impressed from the bases of the teeth. It must also be 

 noted that the metatibia?, while arcuate in basal half, may also be 

 straight and slighth^ widened in the apical half (see wickhami). 



The tibia? are distinctly arcuate in basal half. The articular 

 cavities are more or less open and the tarsal grooves more or less well 

 developed, although rather narrow and usually defined by asperate 

 margins. The floors are quite smooth. 



The protibise are distinctly carinate externall}^, and tlie meso- and 

 metatibia? are scarcely at all carinate externally. 



The tarsi are usually quite stout and moderate in length. 



The protarsi are about a sixth of their length shorter than a meso- 

 tarsus. Joints two, three, and four are short, subequal, and distinctly 

 wider than long, and together distinctly shorter than the fifth; the 

 first is slightly longer than the second. 



Each mesotarsus is about a seventh of its length shorter than a 

 metatarsus. Joints two, three, and four are subequal and evidently 

 just a little wider than long, and together about equal to the fifth; 

 the first is about as long as wide. 



The metatarsi are distinctly less than half as long as a metatibia. 

 Joints two and three are subequal and longer than wide, and together 

 decidedly shorter than the fourth ; the first is about one-half longer 

 than wide.

 and rather sparsely punctate, puncuires moderate in size and denser
