REVISION OF ELEODIINI BLAISDELL. 391 



The luesosternuiii is strongly prominent ventrally. arcuately and 

 vertically declivous, but feebly concave. 



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

 of a mesotibia at middle. 



The abdominal intercoxal process is quadrate (male) or transverse 

 (female) and a fourth (male) to a third (female) of its own width 

 broader than the metasternal salient. 



The abdominal process is equal in length to the second segment ; 

 the post-coxal part of the first is equal to the length of the third. 

 In the male the third is but slightly longer than the fourth; in the 

 female the third is about onedialf longer than the fourth. 



The profemora are moderately clavate; the mesofemora feebly 

 widened, with the superior and inferior surface lines slightly arcuate; 

 the metafemora are subequal in width throughout, with the superior 

 and inferior surface lines parallel. 



The tibial grooves reach nearly to the femoral base on all of the 

 femora, but more or less evanescent internally on the meso- and 

 metafemora; their margins are feebly developed and sul)asperate. 



The tibia? are without tarsal grooves; the articular cavities are 

 closed. The protibia^ are slightly carinate externally in basal half. 



The tarsi are comparatively moderate in length and stoutness.

Subgenus METABLAPYLIS, new. 



The mentum has the middle lobe very small and the lateral lobes 

 fully exposed (Plate (>, hg. IC)). These characters appear unique in 

 the genus Eleode^, although in some parts the middle lobe is reduced 

 in size, but never so completely and persistently. 



The anterior tarsi are similar in the sexes, simple beneath, the 

 grooves entire. 



The anterior femora are more or less sinuate beneath in apical fifth, 

 never dentate, although in iiM/rhid the rudiments are present. The 

 anterior tibiae are more or less constricted at base, and recalls similar 

 characters in BJiipi/Jls and phtnlpeiniis {Discogenid) ; this appears 

 to be an atavistic character, and bears an inverse relation to the 

 femoral teeth; it is at times feebly indicated in nearly all of the 

 subgenera. 



Schiixirzii forms an exception, and in the strict sense does not 

 belong here; the first joint of the protarsi is distinctly and unmis- 

 takably thickened at tip beneath, and can only be considered as a tem- 

 l)orarv constituent of the i)resent subgenus until more can be learned 

 of its relationships, and this depends upon more extensive collecting.
