In this species of the genus Cicindela there are several very marked varieties, differing in the number, size and, manner of disposing of the markings on the elytra; while other less marked, yet distinct forms, coming between the more marked ones, constantly occur. Being struck with the considerable differences between the specimens I have collected of this species, it occurred to me that my observations on the subject might be of interest to some others; and with that view I give them.
