The date listed for Agrilus otiosus [as] "Say, 1833" is incorrect. According to: LeConte, J.L. 1859. "The complete writings of Thomas Say on the entomology of North America" vol.II, Bailliere Bros., New York, reprinted by Arno Press 1978 814pp., the description of A. otiosus appears in the continuation of vol.6 Journal of the Academy of Natural Sciences of Philadelphia dated 1836; pp.155-190, on pg.164.
