Explanation of Plate VI. 
Mosaic Monsters. 
Fig. 68. A "rgiht (moricaud)- left (normal) mosaic". 
Fig. 69. A normal-marked larva; the dark spots on the left half re- 
present the "oily" areas. 
Fig. 70. A striped-normal mosaic ; the right anterior and left posterior 
quarters are practically striped, the right posterior and left 
anterior quarters are, for the most part, normal-marked. 
Fig. 71. ditto, ventral view; the median spots anterior to segment 
VIII are in asymmetrical form. 
Fig. 72. A striped-normal mosaic. In segments VI, VII and VIII 
the striped (black) and normal (white) characters are inter- 
spersed on both sides ; in the other segments the right is, 
speaking in general, normal, the left striped. 
Fig. 73. Moricaud-quail mosaic. In the left half, the moricaud 
pattern is absent in portions as shown by white patches 
scattered about. 
Figs. 74-76. Striped larvae with white patches, the distribution of 
which seems scarcely influenced by the axis of symmetry.
