CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 91 



Cryptocephalus tinctus Leconte

? Cryptocephalus fasciatus Saj^, 1824, p. 437. 

 Cryptocephalus tinctus Leconte, 1880, p. 203. 



Pronotum: Light orange to reddish (sometimes clouded with 

 darkish), sometimes with margins and scattered areas yellowisli, 

 punctures often more darkly pigmented. Usually with dual punc- 

 tation, smaller punctures often obscure to very sparse, larger punc- 

 tures quite large, coarse. 



Elytra: Light orange, each elytron usually with three vague to 

 rather distinct, darker orange to reddish, transverse, undulating bands. 

 Dark bands arranged as follows: one basal, one behind middle, one 

 apical and narrow, often bands expanded and nearly meeting. With 

 nine sometimes slightly irregular rows of punctures, occasionally rows 

 six and seven confused; punctures a little larger, denser than usual, 

 slightly finer to apex; inner and outer rows obscured at apex by 

 confused punctures. 



Prostemum: Anterior margin in male produced into a short, usually 

 pointed lobe; anterior margin in female not produced to feebly, 

 broadly produced. 



Length: 2.8 to 4.5 mm. 



Discussion. — C. fasciatus has long been considered a possible 

 synonym of lateritius, but unfortunately the description of fasciatus 

 does not allow it to be placed with certainty. The locality of collec- 

 tion was given by Say as the Konza River, Missouri; this fits more 

 closely with the distribution of tinctus (quite similar morphologically 

 to lateritius) than it does with the distribution of lateritius. On that 

 basis, I consider it more likely a synonym of tinctus than lateritius. 

 C. lateritius is known only from Florida, Georgia, and North Caro- 

 lina ; see below for the distribution of tinctus. 



Distribution. — The USNM collection has 28 specimens from 

 Massachusetts, New Jersey, New York, District of Columbia, Penn- 

 sylvania, North Carolina, Virginia, South Carolina, Iowa, and Kansas.

Figures 110, 137 



General: Body 1.7 times as long as wide; dorsal surface rather 

 shining, elytra less so than pronotum; dorsal surface without pubes- 

 cense; most of ventral surface with short, sparse pubescence. 



Head: Front and clypeus creamy yellow, an inverted V from vertex 

 to antennal insertions and labrum reddish; front with moderate- 

 sized, rather coarse punctures; clypeus with basal margm obsolete,
