EEVISIOlSr OF ELEODIINI BLAISDELL. 125 



elytra are more or less coarsely and niuricately punctate at the sides 

 and not pubescent. 



In typical extricata the pronotum is very finely punctulate; in a 

 large series, however, the punctures will be observed to become 

 denser and coarser, until in the punctate form there is an approach 

 to (jranulata and letcheri in that respect. 



Arcmata is smooth and finely sculptured throughout and the an- 

 terior femora of the males are not dentate. 



In doubtful instances the female genital characters should be 

 studied. 



The mentum is rather large in the female and subparabolic in 

 outline; smaller and triangulo-parabolic in the male; surface convex 

 at middle and more or less excavated laterally, subscabrously punc- 

 tate and not noticeably setigerous. 



The prosternum is not strongly protuberant ventrally with the 

 coxa^, arcuate antero-posteriorly between the coxa^ and more or less 

 strongly mucronate behind. 



The mesosternum is more or less strongly concave and arcuate to a 

 varying degree. 



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

 of the mesotibia at apical third. 



The abdominal process is quadrate and equal in width to the 

 metasternal salient ; in the most pronounced example of cognata 

 before me the process is just a little wider than long and also just the 

 least wider than the metasternal salient. 



The abdominal process, post-coxal part of the same segment, and 

 the third segment are subequal in length; the second is twice the 

 length of the fourth. 



The legs are variable in length and stoutness, and what would be 

 expected in a very variable species. 



The profemora are more or less clavate, and the tibiae are without 

 tarsal grooves. 



The tarsi are variable in length and stoutness, longest in the 

 elongate form and distinctly stoutest in the punctate form. But 

 slightly longer and stouter in the inale.
