NORTH AMERICAN COLEOPTKRA. / 



it this variety may be separated from the preceding by having the 

 head and thorax always of dark color. 



There seems to be no law of distribution of these varieties, except 

 in the case of the entirely piceous forms which seem restricted to the 

 more northern regions. 



In distribution, as a whole, the species crosses our continent from 

 the New England States to Vancouver and northward. In the At- 

 lantic region it is found in North Carolina. From the Lake Superior 

 region it passes southward through Colorado to Arizona, and on the 

 Pacific coast from Vancouver southward in the more elevated regions 

 through California.

 The species of this genus have not yet been collected with sufficient 

 care and such numbers as to warrant any positive assertion regarding 

 their synonymy. It is very j^robable that the seven given below 

 should be reduced to four, and possibly to three. 



Tliat they may be identified by their present names, the following 

 table is presented : 

 Body as seeu from above of one color. 



Pitchy-black abiiormis. 



Entirely yellowish Kirbyi. 



Body above bi-colored. 

 Elytra entirely black. 



Head entirely yellow; puiictares of elytra large and more distant than 



their diameters sciitellaris. 



Occiput black; elytral punctures close.. coiisaiigiiiiiea. 



Elytra parti -colored. 

 Thorax entirely yellow. 



Elytra with di.scal piceous area, touching the base, not reaching the apex ; 



autennse entirely yellow <*alilbriiica. 



Elytra with a cordiform discal space, the suture narrowly and side margin 

 yellow; outer half of the antennae piceous; elytral punctures very 



close piiberiila. 



Thorax with a discal piceous area divided at middle by a yellow line. 



Elytra with a common oval, or cordiform spot and the apex pale ; antenniv 



pale variaiis. 



From our ])resent knowledge these sjjecies are distributed as fol- 

 lows :
