C. marmorata Uhler. (PL xvii, 6.) 



Proc. Bost. Soc. Nat. Hist., xix, 415, 1878.

 hemielytral pattern is made up of small spots, which in part unite 

 to form two apical bands. Its chief food plant is goldenrod. The 

 variety mformis Parshley is frequently met with.

Ohio St. Univ. Bull., xx, 230, 1916. 



This species feeds usually on the mulberry, but has been reported 

 also from basswood ; it is easily recognized by its almost uniform 

 yellowish brown color. Its occurrence in New England is 

 probable, but not as yet definitely reported.

Het. New Harm., 27, 1832.

 hood. The variety mali Gibson lacks the apical band on the
