Extract

Such knowledge as we have of the family Lacciferidae is very largely embodied in an excellent monograph published in 1923 and 1925 by J. C. Chamberlin (Bull. Ent. Res. 14, pp. 147–212 and 16, pp. 31–41). The comparatively speaking limited geographical distribution of the various generic groups is well brought out in this monograph. Thus, for instance, the genera Tachardiella and Austrotachardiella are apparently confined to North and South America, Metatachardia to Ceylon, Austrotachardia to Australia, Tachardia to India and the Far East. Chamberlin further states (p. 149) “ in general it may be said that the species of this group are tropical or sub-tropical, apparently reaching their greatest abundance in regions of limited rainfall.” How far this comparatively limited and well-defined zonal distribution of the various genera will hold good as further material is collected will prove of the greatest interest.
