One spécimen , New York , The tkep posterior dorsal chan- 

 nel and the fine punclures of iJie interstices of the elylra will 

 dislingiiish this from ihe next species ( te^iax ) : it may possibiy 

 Le the maie of (he prcceding species (pirfitiax) , but ihere is 

 no évidence of it except the gênerai similarity of sculpture : 

 the pubescence is denser and not so long : the thorax , ho- 

 wever , bears pretty much the same relation in the two species 

 as in tiie two sexes of C. cribulosus.
