N THE 25 ,years sinc~ th~ appeal'lUl~~ of.the "Cla?sificntlon of S~aJe I Insects of the SubfanllIy Orthezllnae" (MorrIson 30),4 va,rlOllfl lots of additional study material have accumulated, including severnl new species. In ac]dition, flllther evidence bearing on the elassificatioll presented in that p!Lper, a few changes ill tIle status of certain of the specimens discussed there, and a number of species described by other workers have become known during this period. Since these additions more than double thenumber of known species.in this group, the. added information is presented in this snpplement. An effort has been mad!3

The limitations on illustrations for this group of coccic1s were dis­ • cussed in the nrst paper (35, p. 97). Since these comments apply equally well to this paper, they should be reviewed before any attempt is made to utilize the lllustrations here presented.
