smaller punctures very sparse to absent, larger punctures minute, 

 sparse. 



Elytra: Dark reddish to black, lateral margin below and behind 

 humerus and epipleuron vaguely reddish to yellowish. With seven 

 rows of regular punctures and a short series behind humerus; punctures 

 as large, dense as usual, finer apically; inner and outer rows distinct at 

 apex, usually clearly meeting. 



Prosternum: Anterior margin of both sexes produced downward 

 into a short, rather broad lobe. 



Length: 2.8 to 3.5 mm. 



Distribution. — The 12 specimens examined are from Florida, 

 Georgia, Alabama, Tennessee, Kentucky, Arkansas, and Mississippi.

 Cryptocephalus notatus Fab. 1787, p. 83. 



Pronotum: Dark brown to (usually) black, nearly always with a 

 bluish tint; punctation dual, larger punctures minute to (infrequently) 

 moderate in size and rather coarse. 



Elytra: Dark brown to (usually) black, each elytron with light orange 

 markings as follows: a large spot at side from base of fourth stria, 

 arching to about middle of elytron at lateral margin (humerus usually 

 dark); a large apical spot; basal spot never attaining scutellum or 

 apical spot. With eight and sometimes nine rows of punctures, fifth 

 row sometimes, sixth nearly always confused, sometimes double, 

 seventh row sometimes confused; punctures fine and dense as usual, 

 finer apically; inner and outer rows distinct at apex, usually clearly 

 meeting. 



Prosternum: Anterior margin in male with a distinct, sharp, ven- 

 trally directed spine; anterior margin in female with a more or less 

 distinct, sometimes pointed lobe. 



Length: 3.3 to 4.8 mm. 



Discussion. — Usually there are eight rows of punctures on each 

 elytron, and the sixth row is distinctly confused. In some, the punc- 

 tures of the sixth row tend to form a nearly double row, and, at the 

 extreme, they form two distinct, close rows; in such individuals, there 

 are nine rather than eight rows of punctures. 



The male genitalia of n. notatus, n. fulvipennis, n. quadrimaculatus, 

 and n. sellatiis have been cleared, compared, and found essentially 

 identical. 



Distribution. — -The 141 specimens in the USNM collection are 

 from Ontario, Quebec, Maine, Vermont, New Hampshhe, Connecticut, 

 Rhode Island, Massachusetts, New York, New Jersey, Pennsylvania,
