is twice as long as the fourtli ; the second is a little longer than the 

 post-coxal part of the first. 



The abdominal salient is about a fourth of its width broader than 

 that of the metasternal process. 



The metasterninn laterally between the cox?e in length is about 

 equal to a mesotibia at middle. 



The tibial grooves of the femora are well develoj^ed and scarcely 

 entire, the margins are cariniform and become evanescent, usually at 

 the internal fourth ; their floors are smooth and quite flat. 



The anterior margin of the profemoral grooves become quite sud- 

 denly dentately laminate at about the external fourth. 



The protibia) are more or less distinctly carinate externall}^ and 

 feebly compressed, their tarsal grooves are more or less evident and 

 scabrous and the articular cavities are closed. 



The mesotibise have the grooves more or less developed and muri- 

 cate and the articLdar cavities are closed; externally obsoletely cari- 

 nate in basal fourth. The metatibise are more or less flattened exter- 

 nally and roughly sculptured, not at all carinate and the articular 

 cavities closed. 



The tarsi are moderate in length and quite stout. 



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

 tarsus. Joints two, three, and four are quite closely articulated, sub- 

 equal, Avicler than long and together about equal to the fifth; the first 

 is about as long as wide. 



The mesotarsi are very little shorter — about an eighth of their 

 length — than a metatarsus. Joints two, three, and four are subequal, 

 as long as wide, and together quite equal to the fifth; the first is 

 slightly shorter than the next two taken together. 



The metatarsi are a little less than half as long as a metatibia. 

 Joints two and three are subequal and distinctly longer than wide, 

 together just the least shorter than the fourth, and a little longer 

 than the first. 



ELEODES ACUTICAUDA var. LATICOLLIS LeConte. 



Elongate oval, more or less shining and smooth, strongly convex 

 and not caudate, interstitial punctures of the elytra more or less 

 Tnuricate. 



Head rather large, twice as wide as long, rather moderately con- 

 vex, very feebly and broadly impressed laterally, finely, irregularly 

 and rather spai'sely jjunctate, quite densely so laterally. ]:)unctiires 

 finely muricate, frontal suture obsolete. Antennrv moderately stout, 

 reaching to the base of the prothorax, outer four joints feebly com- 

 pressed and very slightly dilated, third joint very slightly longer than 

 the next two combined, fourth slightly longer than the fifth, the
