CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 41 



representing the outer vitta. The female ranges in length from 5.0 to 

 5.8 mm.; the inner vitta is rarely expanded and the pronotum is 

 usually darker than that of the male. 



Leconte (1880, p. 202) distinguished carinatus (described from 

 Kansas) on the form of the prosternum, i.e., "carinate for its whole 

 length." Examination of a long series of individuals of calidus and 

 specimens from Kansas assignable to carinatus shows this character 

 to be variable in its development. The prosternum of most specimens 

 of calidus is flat or sUghtly concave, but in occasional individuals, this 

 is convex to obtusely carinate. Specimens from Kansas usually have 

 the prosternum carinate, but this carina ranges from distinct to 

 absent. I find no other external characters that would serve to dis- 

 tinguish the category I beUeve to be Leconte's carinatus from calidus. 

 The only discrepancy I find in Leconte's description is the size given 

 for his male type (5.5 mm.). The size range of males of calidus is 4.2 

 to 4.5 mm.; the female is 4.8 to 5.6 mm. long. 



I am not convinced that a single species is represented in the 

 lengthy series I have assigned to this species (see notes under bi- 

 spinus) . Females from various parts of the range closely approach 

 hispinus in size and general coloration. Males often exhibit an expan- 

 sion or reduction of the elytral vittae. 



Biological notes from labels record specimens from leaf of Lathyrus 

 japonicus Willd. (''Lathyrus maritimus") and Lespedeza serecea Miq. 

 {"Lespedeza serecia"). 



Distribution. — I have assigned 252 specimens to this species. 

 They were collected in the following areas: Massachusetts, Connecti- 

 cut, New York, New Jersey, Pennsylvania, Marj^land, Virginia, 

 North Carolina, South CaroUna, Alabama, Florida, Tennessee, Ohio, 

 Ontario, Indiana, Michigan, Wisconsin, Mississippi, Kansas, Ne- 

 braska, Colorado, Oklahoma, Iowa, South Dakota, and Montana. 



Two individuals in the collection bear Cahfornia as the locaHty of 

 collection, but it is likely that these labels are in error.

 Cryptocephalus castaneus Leconte, 1880, p. 200. 



Pronotum: Creamy yellow to light orange with four broad, black 

 to red or dark orange, longitudinal vittae, often expanded; median 

 two vittae rarely meeting along midline; each lateral vitta usually 

 arcuate or sinuate, frequently expanded and joining imier vitta; dark 

 markings nearly always sharply delimited. Punctation dual, larger 

 punctures minute to (rarely) rather large and coarse, at side usually 

 with a distinct, shallow depression.
