REVISION OF ELEODIINI BLAISDELL. 463 



I am indebted to Mr. Warren Knaus for this interestin<j: addition to 

 our list. 



General observations. — The mentuin is rather small, feebl}^ trans- 

 verse, more or less arcuate anteriorly, although at times apparently 

 subtruncate, sometimes feebly impressed at apex so as to appear some- 

 Avhat emarginate; surface feebly convex, glabrous, and obsoletely 

 punctate at center, narrowly impressed peripherally within the mar- 

 gin, there opaque and distinctly punctate. 



Prosternum less suddenly protuberant ventrally than in pJaiuim, 

 otherwise the same. 



The mesosternum is quite vertical and arcuately declivous, more or 

 less concave as usual. 



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

 of a mesotibia at apex. 



The metasternal and abdominal salients are quite ecjual in width. 

 The abdominal process is a little longer than wide. The post-coxal 

 portion of the first abdominal segment is about equal to the third in 

 length ; the second is about twice as long as the fourth segment. 



The tibial grooves of the femora are well developed, more or less 

 concave, but not strongly so. The margins are subcariniform exter- 

 nally, becoming more or less evanescent internally. On the profemora 

 the grooves have the margins slightly arcuate and about attaining 

 the femoral base; those of the meso- and metafemora have the mar- 

 gins quite straight, scarcely attaining the base on the former and 

 evanescent at basal fifth on the latter. 



The protibia? are feebly compressed and distinctly carinate ex- 

 ternally; tarsal grooves more or less obsolete, articular cavities 

 closed. On the meso- and metatibia^ the grooves are more or less de- 

 veloped and narrow on apical two-thirds, slightly glabrous, margins 

 asperate, and the articular cavities are closed. 



The tarsi are the same as in planum. 



The protarsi are about two to three-fifths of their length shorter 

 than a mesotarsus, joints two to four subequal in length and scarcely 

 as long as wide: the first joint is a little longer than wide; the fifth 

 is just the least longer than the three preceding joints taken together. 



The mesotarsi are about two-fifths of their length shorter than a 

 metatarsus. Joints two to four, inclusive, are subequal in length and 

 slightly longer than wide; the first joint is about one-half longer than 

 wide ; the fifth is slightly shorter than the preceding three joints taken 

 together. 



The metatarsi are distinctly more than a half longer than their 

 respective tibia. Joints two and three are subequal in length and 

 distinctly more than one-half longer than wide, and together as long 

 as the fourth ; the first is scarcely as long as the next two taken 

 together.
