Number of specimens studied, !>0. 



Type in the Mannerheim collection. 



Type-locality. — " California." 



Salient type-character. — Opaque. Thorax with the sides rounded, 

 densely rugoso-punctate. El3'tra subquadrate. apex strongly decli- 

 vous, dorsum deplanate, densely granulate, granules reclinate, rough 

 and piliferous (Mannerheim). 



Diagnostic characters. — Tu general form like cordata^ from which 

 it differs in having the elytra sculptured with small rounded tuber- 

 cles. The form of the tubercles differs, in some specimens distinctl}'' 

 rounded, in others reclinate and often more or less muricate. In 

 some males there is evidence of rows. 



The series from Walla Walla, Washington, have the elytra depla- 

 nate and sub(|uadrate; these characters are less marked in the other 

 specimens. In the race hrunnipes the legs are brownish and more 

 distinctly piliferous. at least in those specimens from Nevada. 



Viator, described by LeConte from Fort Bridger, is a male, Avith 

 the elytral tubercles large and extending almost to the suture. 

 Colonel Casey also considers that this form does not differ from 

 ordinary males of pimelioides. 



Suhligata is one of the forms associated with cordata by LeConte: 

 he obtained specimens from Oregon. Doctor Horn considered it a 

 synonym of the present species, and which is undoubtedly correct. 



For remarks upon variation in sculi)turing see cordata. 



The legs are variable, usually more slender in the males and 

 stouter in the fenuiles. The thorax and humeri vary as in cordata. 



ELEODES PIMELIOIDES var. BRUNNIPES Casey. 



Rather robust, moderately convex, coarsely, densely sculptured and 

 dull, black; legs dark brown throughout. 



Head large, fully two-thirds as wide as the prothorax, coarsely, 

 extremely densely j^unctate and scabrous. Antenna' longer than the
