. Carnegie Institution of Washington publication. 62 EVOLUTION IN COLOR-PATTERN OF THE LADY-BEETLES. The typical pattern is rare with us. Nearly all of our specimens in North America are of the variety quinquenotata. The variety nugatoria is common in the Western States, but not in the Eastern. Mulsant states that it is found more often in the south of Europe than in the north. Further knowledge of this distribution would be desirable. The extreme of pigment reduction shown is the form A from Washington. This is in good accord with the general belief that C. californica is a spotless deri- vat

The extreme of pigment reduction shown is the form A from Washington. This is in good accord with the general belief that C. californica is a spotless deri- vative of C. transversoguttata and favors the idea of their close relation- ship. The variation in the pronotum is shown in fig. e f 9 h FIG. 53.—Offspring of 405 ?. n>.
