It is, however, a fairly good crude method in obtaining preliminary data of conditions in a population. Examination of the directions of diversity found in L. panamensis (fig. 24) shows differences in the areas, but the general result is clearly a delimited vari- ation. In restricted localities the population shows remarkable delimited move- ment of the population as a whole in certain directions. To what agencies these movements and responses are due is not determined by the methods of the census; an endless array of possible causes for the observed effects could be suggested and plausibilities put together to no purpose Fig. 25.—Sliowing directions of varia- tion, especially in spots c, h, and e, in L. signaticollis, and some results which these directions of variation may produce in the production of pattern differences. In L. signaticollis the same spot (c) occurs and shows some of the same direc- tions of variation as in L. undedmlineata, but in area it much exceeds the first species. In figure 25 are shown the variations thus far discovered, together with the results produced in the pattern. In this species spot c is most commonly present as a round area of variable size, is never absent, with the observed.
