HEMICOCCDSLE. 



In preparing the synopsis of the sub-families of the 

 Coccidae given in vol. i, p. 67, of this work, I adopted 

 Mr. Green's brief diagnosis of the sub-family Hemicoc- 

 cinaa. I did so chiefly because I had not, at that time, 

 sufficient material for fully studying the genus Kermes. 

 Having now obtained fresh material, I find that the 

 typical females of this genus have not " cleft extremity 

 and anal plates as in Lecanium." The anal orifice, 

 which is non-setiferous, is placed well within the
