EEVISION OF ELEODITNT BLAISDELD. 95 



The intercoxal process of the abdomen is subquadrate (male) or 

 slightly transverse (female) and about one-fourth of its width wider 

 than the metasternal salient. 



The metasternum laterally between the coxse is as long as the width 

 of a mesotibia at the extreme apex. 



The post-coxal part of the first abdominal segment is equal in 

 length to the process, and the latter to that of the third segment. 



In the sexes the second segment is twice as long as the fourth. 



The profemora are more or less distinctly clavate; the grooves are 

 moderately broad and the margins subcariniform, more or less asperu- 

 late, becoming contiguous and evanescent at basal third. 



The mesofemora are scarcely or very feebly clavate, grooves quite 

 plane, margins feeble and asperulate, evanescent at middle before 

 becoming contiguous. 



The metafemora are not at all widened externally and the superior 

 and inferior surface lines are quite parallel; grooves as on the meso- 

 femora. 



The tibiae may be more or less feebly arcuate, tarsal grooves absent, 

 articular cavities closed. 



The pro- and mesotibise are somewhat inwardly produced at apex. 

 The protibiae are sometimes quite distinctly carinate externally in 

 basal half, noticeably so in the largest female before me. 



Tarsi variable in stoutness. The protarsi are about one-half (male) 

 or one-fourth (female) of their length shorter than a mesotarsus. 

 Joints two, three, and four subequal in size, and together a little 

 longer than the fifth; the first slightly shorter than the third and 

 fourth taken together. 



The mesotarsi are about a ninth (male) or a fifth (female) of their 

 length shorter than a metatarsus. Joints two, three, and four feeblj'- 

 decreasing in length in the order named; the fifth subequal to the 

 combined lengths of the second and third, the first to the third and 

 fourth. 



A metatarsus is about a half (male) or a third (female) of its 

 length shorter than its metatibia. Joints two and three are subequal, 

 and together about equal to the fourth, which is subequal to the first.
