Cryptocephalus viUatus Haldeman, 1849, p. 250 [preoccupied, original spelling 

 vitatus]. 



Pronotum: Creamy yellow to light orange, with three rather broad, 

 more or less distinct, longitudinal, red to nearly black vittae; median 

 vitta broadest at its middle, lateral two broadest at their base. Puncta- 

 tion usually dual; surface often alutaceous, obscuring smaller punc- 

 tures; larger punctures small to moderately large and coarse. 



Elytra: Creamy yellow to light orange, usually with red to nearly 

 black markings as follows: at basal fourth of third interval (often 

 reduced to absent), at middle of fifth interval to apex; entire sLxth and 

 seventh intervals from base to apex (sometimes reduced, rarely indi- 

 cated only at base). With eight rows of often pigmented punctures; 

 sixth and seventh rows confused; punctures often a little larger, denser 

 than usual, finer at elytral apex; inner and outer rows at apex distinct, 

 uniting clearly. 



Prosternum: Anterior margin in both sexes not produced, nearly 

 evenly arcuate tlu'oughout. 



Length: 3.3 to 4.3 mm. 



Distribution. — The 43 individuals in the U.S. National Museum 

 are from Massachusetts, Connecticut, Rhode Island, New York, New 

 Jersey, Maryland, Virginia, South Carolina, Florida, Alabama, Il- 

 linois, Iowa, and Texas. A single specimen represents the Texas 

 record; it is from College Station; this record could be in error.

 Cryptocephalus trizonatus SufTrian, 1858, p. 372. 



Pronotum: Light orange with a transverse, sharply delimited, red 

 to nearly black band, pointed on each side, nearly or quite attaining 

 lateral margin. 



Elytra: Light orange, each elytron with two broad, transverse 

 bands and apical tip red to dark red; dark bands sharply delimited, 

 leaving usually narrower orange bands at base, middle, and before 

 extreme apex. With seven or eight rows of pigmented punctures, 

 fourth to eighth rows often reduced, especially within median orange 

 band; punctures larger, sparser than usual, finer at elytral apex; inner 

 and outer rows distinct at apex, clearly meeting.
