REVISION OF ELEODIINI BLAISDELL. 271 



It will be observed that the sides of the front at the junction with 

 the epistoma are frequently slightly emarginate at the suture. 



General oh nervations. — The mentum is moderate and the middle 

 lobe is nearly parabolic, being arcuately rounded in the examples that 

 I have seen; the surface is very feebly convex and sometimes very 

 feebly foveate laterally. 



The prosternum is horizontal or more or less convex between thQ 

 coxa;, surface longitudinally grooved or concave posteriorly; mucro- 

 nate behind, truncate or subtruncate. The ante-coxal portion is quite 

 short at times and with the cox?p prominent ventrally. 



jNIesosternum as in armata. 



The abdominal process is subquadrate, slightly transverse, and 

 about as wide as the post-coxal portion is long; the second segment is 

 about twice as long as the fourth ; the third about a third of its length 

 shorter than the second. 



The abdominal salient is slightly wider than the metasternal salient. 



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

 width of a mesotibia at apex. 



The tibial grooves of the femora are well developed and strongl}^ 

 defined, broader in the peninsular examples and somewhat contracted 

 in the insular specimens. The anterior margins of all are quite carin- 

 iform, most strongly so in the robust examples, and strongly den- 

 tately laminate, internally rather gradually passing into the teeth. 

 The floors are opaque, sometimes subasperate on the profemora, 

 generally so on the meso- and metafemora. The anterior grooves 

 have the sides more or less arcuate and quite attaining the femoral 

 base ; on the other femora the sides of the grooves are more or less 

 evanescent internally; on the mesofemora the grooves attain the in- 

 ner fifth and on the metafemora to about the inner fourth. All of the 

 femora are longitudinally impressed iuAvardly from the tooth along 

 the lower part of the anterior surface. 



The protibise are more or less arcuate externally and distinctly 

 carinate ; the tarsal grooves are more or less developed and sca- 

 brously sculptured. In the peninsular specimens the articular cavities 

 are closed and in the insular more or less open. 



The mesotibicT are more or less carinate in basal third externally. 

 The metatibia^ are not carinate, and both have the articular cavities 

 closed. The tarsal grooves of the mesotibiae are more or less evident 

 and scabrous. The metatibise are flattened or feebly grooved and 

 muricate externally; quite C3dindrical in transverse section. 



The tarsi are variable, moderately slender to quite stout, quite 

 moderate in length. 



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

 tarsus. Joints quite closely articulated, second, third, and fourth
