caudal, quadrate. The surface somewhat shining'; punctation 

 exceedingly evident, the punctures deep and broad ; elytra smooth 

 and glabrous. The margins of the elytra slightly rimmed. The 

 epipleurum very wide cephalad and tapering, gradually, caudad. 



This interesting and distinct species is related to E. caudata, 

 and E. parvicollis, but is separated from both by the very punc- 

 tate elytra like E. caudata; smooth and glabrous; and especially 

 by the very wide epipleuras, which are extraordinary, and nothing 

 approaching it in this respect. It was very puzzling and the 

 inclination was to put it in a different family, but it is placed 

 here provisionally at least.

Greatest width of epipleurum 2.5

Eleodes consobrina LeConte. 

 PI. fig. 20. 



Specimen No. 10021, Univ. Calif. Col. Invert. Palae. Asphalt beds at 

 Rosemary, near Los Angeles. 



The abdomen and elytra are well preserved, and characteristic 

 of this species. The punctation and striation are very distinct. 



Eleodes laticoleis LeConte. 



Forma muricata minor. 



PI. 15, fig. 8; PI. 1(3, figs. 19, 23, and 25. 



Specimen No. 10022, Univ. Calif. Col. Invert. Palae. Asphalt beds at 

 Rosemary, near Los Angeles. 



The specimens are well preserved and characteristic, but all 

 belong to the small, muricate form. There is considerable vari- 

 ation in the specimens, but there is as much in the living forms ; 

 and although some are strikingly different from living forms, it 

 would hardly be of value to give names to such a variable group. 

 There is a specimen 13 mm. long and another 19 mm. long.
