In his recently published work, “A Classification of the Higher Groups and Genera of the Coccid Family Margarodidae” (U.S. Dept.Agr., Tech. Bull. no. 52, July 1928), Mr. H. Morrison has made some sweeping alterationsin the previously accepted status of tribes and genera, some of which may possibly be open to criticism. But his classification is so vastly superior to anything hitherto attempted that—if only for the sake of uniformity—it should be adopted until a still better complete classification has been propounded. So far as it affects the matter dealt with in the following paper the only novelty is the erection of a new subfamily, Coelostomidiinae, with several new tribes and genera, to accommodate the species hitherto included in Coelostomidia, together with several allied genera.
