The optical properties and retinal structures of the larval
eyes of the tiger beetle were reported in detail for several
species by Friederichs (1931). The posterior focal length
was also obtained from image magnifications, as also in
the present study. The data obtained in the present study
could not be compared simply with those reported byFriederichs (1931), however, because of the different size
of eyes used between the two works. Even so, if we compare
stemmata of similar sizes in the two studies, the optical
and morphological data are very close between both.
