 antedivisa" for Lacordaire's Var. A which has the basal 



elytral band separated into spots. 



Boyle (1954) recognized that both Schaef fer' s and 

 Mader' s varieties were part of a clinal change in the color 

 pattern from north to south. He synonymized both under I. 

 q. quadripunctatus (Olivier) . 



Specimens from Bolivia and southwestern Brazil have the 

 legs banded with orange. All other color patterns have the 

 legs entirely black. The geographic range of this "banded- 

 leg" pattern appears to be isolated from those with solid 

 black legs. No morphological differences, including 

 genitalic characters, were found which correlated with leg 

 color. Until more series of specimens are studied from 

 additional localities, its distinctiveness is questionable. 

 I cannot justify giving it subspecific status based on the 

 available information. 



Biology . This common subspecies appears in many 

 regional checklists and occasionally in general texts. 

 Additional references may be found in Hatch's (1928, 1929, 

 1941) indices to keys and local lists of Neartic Coleoptera. 

 Its biology is discussed in the Biology section of the 

 species account above.
