324 REVISION OF THE TENEBRIONlDiE OF AMERICA, 



ters already eiven. The mentum as in Eleodes varies in form without affording reliable 

 data on which to divide the genus. Our species may be arranged as follows: 

 Thorax bicostate, gradually narrowing behind, sides slightly sinuous 



near the hind angles, margin acute, reflexed. bicarinata. 



Thorax not costate, margin not reflexed, sides regularly rounded. 



Legs black; species large. grossa. 



Legs ferruginous; species smaller. 

 Elytra finely costate. 



Thorax as wide at base as base of elytra; elytra not 



pubescent. run pes. 



Thorax narrower at base than elytra; elytra pubescent, pub esc ens. 

 Elytra with series of large, distant, shallow punctures, inter- 

 stices not elevated. 

 Thorax narrower at base than elytra ; elytra glabrous. b S C u ra . 



E. bicarinata, Esch., Zool. Atl. Ill, p. 15, pi. 13, fig. 8. Figured also by Solid-, Baudi e Traqui Studi. 

 En( pi. 11. fig. 1. 



Occurs not rarely at San Francisco and Sacramento, California, under stones, etc. 



Length .30-.40 inch. 



I grossa, Lee, New Species, p. 1 18. 



Entirely black, sub-opaque. 



Occurs on the Island of San Clemente, coast of California. 

 Length .47- 55 inch. 



K. rnfipes, Esch., Zool. Atl. III. p. 15. 



Readily distinguished by the characters given in the table. The humeral angles are 

 more acute than in any specie- excepting hicarinata. 



Occurs abundantly at San Francisco and in the San Joaquin Valley. 

 Length .25-.28 inch. 



I'., pubescens, Lee, Ann. Lye. V.. y>. Ill; Apsena Class. Col. X. A., p. 338. 

 The pubescence of the elytra is very short, erect, and of a yellow color. 

 Occurs at San Diego, San Clemente. and in the Peninsula of California. 

 Length .30-.38 inch. 



!•• obscura, Lec, Epantius Lnn. Lye. V., p. 144; (Eulabis Class. Col. N. A., p. 228. 



Differs from the other species in the sculpture of the elytra. The generic character- 

 are of too feeble value to allow the genus to be retained, as stated in Class. Col. N. A.. 

 p. 228. 



Occurs in the southern part of California. 



Length .30 inch.
