Diagnosis. In this species, the hind femora are not greatly enlarged in comparison to those of the front and middle legs, the pronotum has well developed lateral and posterior marginal beads, and the elytral punctures are arranged in regular striae. The prothorax is dark brown, but the elytra vary from entirely light brown (unusual specimens) to entirely dark brown. In many specimens, the elytra are mostly dark, but with the apical area light. The elytra are not like Metachroma clarkei   in having isolated dark spots or a reticulate pattern. These characters distinguish M. adustum   from all other chrysomelid species known to occur in the Cayman Islands.

Extralimital distribution. Cuba and U.S.A. (Florida) ( Takizawa 2003). We have also examined specimens from several islands in the Bahamas ( BYUC, previously unpublished data).

Plant associations. Outside of the Cayman Islands, this species has been reported in association with Conocarpus erectus   L. ( Combretaceae   ), Eucalyptus   ( Myrtaceae   ), Psidium guajava   L. ( Myrtaceae   ), Rosa   ( Rosaceae   ), and Citrus sinensis   (L.) Osbeck ( Rutaceae   ) ( Clark et al. 2004). As noted in the Material Examined section above, one large series from the Cayman Islands was also collected from C. erectus   .

Comments. Blake (1970) reported this species from Grand Cayman. Probably based on her report, Peck (2005) also listed M. adustum   from Grand Cayman.
