ELEODES ELONGATA Grinnell. 



The type is a right elytron, fully exposed except the epipleural 

 margin, which is sunken into the as2)halt. The humerus and epipleura 

 immediately beneath are free. The specimen is too poor and fragile 

 to give a clear idea of the sculpturing. 



The elytron is in form like that of Eleodes grandicoUis; the punctu- 

 ation is similar, very sparse and small, scarcely at all subasperate, 

 and quite sharply defined ; general surface glabrous and shining. 

 Humerus rounded, and the superior epipleural margin is thin and 

 sharp. 



Length, 21.5 mm.; width, 9 mm. 



Type-specwien. — Number 10025, University California Collection 

 of Invertebrate Palaeontology. 



This species really appears to be a form of grandicoUis; it differs 

 but slightly from some of those of to-day. GiHind'tcoUls is so distinct 

 that an elytron or thorax ought to l)e readily recognized. 



ELEODES BEHRII Grinnell. 



One elytron (left), apical sixth buried in the as])halt, dorsal sur- 

 face and epipleura exposed, and in a fairly good state of preservation. 



The eh'tral hase is truncate, humerus i-ounded and luit in the least 

 prominent; side evenly arcuate; disk mod(>rately convex. l)roadly and 

 evenly arcuately declivous laterally, not striate, punctuation diffuse, 

 rather dense, subasperate, and with a tendency to coalesce in twos and 

 threes, the intervals more or less convex and forming slight trans- 

 verse rugula^. 



Epipleura rather broad and concave, superior margin moderatel}'^ 

 prominent and rather sharp, gently curving upward anteriorly to 

 the humerus, tlience caudad more broadly and arcuately curving 

 downward to apex; surface smooth, sparsely and distinctly punc- 

 tate, punctures moderately small ; there is also a trace of transverse 

 rugulu'. 



This species is without a doubt closely related to eons^hrina or 

 parrleoIUs; the elytral sculpturing is more like that observed in the 

 latter. 



The ej)ii)leural characters are unlike anything known to me; the 

 marked concavity is rarely observed in sporadic instances in individ- 

 uals of to-day; the curve of the superior margin i-^ moi'c strongly 

 downwai'd to a]iex than in any s]:)ecies. Tt is ])ossible that these well- 

 marked characters are the result of warj^ing in the asphalt. 



This species is the only one of the thi-ee inider consideration that 

 probably deserves a name. Tt is surely a true Eleodes (liJupg/is) 

 and not at all worthy of a generic standing, as the author suggest- 

 ively wrote.
