REVISION OF THE TENEBRIONlDiE OF AMERICA, 



tors already given. The mentum as in Elcodes varies in form without affording reliable 

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

 Thorax bicostate, gradually narrowing behind, sides slightly sinuous 



near the hind angles, margin acute, refiexed. b i c a r i n a t a . 



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



1 ,egs black ; species large. g r o s s a . 



Legs ferruginous ; species smaller. 

 Elytra finely costate. 



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



pubescent rufip e s . 



Thorax narrower at base than elytra ; elytra pubescent, p u b e s c e n s . 

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

 stices not elevated. 

 Thorax narrower at base than elytra ; elytra glabrous. o 1) s c u r a . 



E. biearinata, Escb., Zool. Atl. Ill, p. 15, pi. 18, flg. 8. Figured also by Holier, Baudi e TrnquJ Studi. 

 Entom. pi. 1 1, Bg. 1. 



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



Length ;50-.4() inch. 



E. grossa, Leo., N"ew Species, p. 118. 



Entirely black, sub-opaque. 



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



Length .47-55 inch. 



E. ptiflpes, Esoh., Zool. Atl. Ill, p. 15. 



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

 more acute than in any species excepting biearinata. 



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

 Length .2S-.28 inch. 



E. pnbeseens, Leo., Ann. Lye. V., p. Ill; (Apsena) Class. Col. N. A., p. 228. 



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. 



E. obseura, Lee., (Epantius) Ann. Lye. V., p. 144; (Enlabis) Class. Col. N. A., p. 228. 



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

 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 .■]{) inch.
