Elytra: Creamy yellow to orange with markings black to dark 

 reddish or orange and variable. Discal markings of each elytron as 

 follows: with a large basal and somewhat smaller anteapical spot, 

 both frequently attaining suture, both often expanded and broadly 

 joining, when expanded sometimes meeting suture, spots sometimes 

 reduced. Spots at side of elytron variable, small, often with two 

 humeral, one anteapical, and two apical spots, sometimes reduced or 

 joined by discal markings. With eight rows of punctures, sixth and 

 seventh rows confused, sometimes also fifth; usually punctures larger 

 and/or sparser than usual, finer to apex; inner and outer rows distinct 

 at apex and nearly always clearly meeting. 



Presternum: Anterior margin in female somewhat produced into a 

 broad or somewhat pointed lobe; anterior margin m male distinctly 

 produced into a downward, pointed lobe. 



Length: 3.9 to 5.3 mm. 



Discussion. — At one extreme of development of the color pattern, 

 each elytron bears two large discal spots and four smaller spots 

 laterally; often the discal spots are confluent at the suture. At the 

 other extreme, the discal spots of each elytron are broadly confluent, 

 thus forming a broad vitta; sometimes these vittae meet at the suture, 

 usually they do not. Those specimens bearing broad vittae have three 

 or four lateral spots. 



Label data record specimens as occurring on strawberry, willows, 

 blackberry, holly, and alfalfa. 



Distribution. — Nearly aU the 111 specimens in the USNM coUec- 

 tion are from California, Arizona, and New Mexico. Two specimens 

 ■with identical data have Massachusetts as the locality of coUection; 

 this is almost certainly in error. Only two specimens represent the 

 Arizona record and a single one the New Mexico record; the other 106 

 specimens are from California.

Pronotum: Almost uniformly light orange with more or less distinct 

 fine speckhng, this absent in two vague basal obhque areas and at 

 lateral and apical margins. Punctation dual, smaUer punctures minute 

 and dense, larger punctures very smaU, not dense. 



Elytra: Nearly uniformly hght orange, punctures dark, intervals 

 four and six sometimes vaguely darker, humerus more or less clouded. 

 With seven distinct and even rows of punctures and a sliort series 

 behind humerus, punctures fine and dense, finer to apex as usual; 

 inner and outer rows distinct at apex, not or just meeting.
