This data is from a paper by A. A. Lubischew, "On the Use of
Discriminant Functions in Taxonomy", Biometrics, Dec 1962, pp.455-477.
There are three species of flea-beetles: Ch. concinna, Ch. heptapotamica,
and Ch. heikertingeri, and 6 measurements on each.
1 = width of the first joint of the first tarsus in microns
(the sum of measurements for both tarsi).
2 = the same for the second joint.
3 = the maximal width of the aedeagus in the fore-part in microns.
4 = the front angle of the aedeagus ( 1 unit = 7.5 degrees).
5 = the maximal width of the head between the external edges of the
eyes in 0.01 mm.
6 = the aedeagus width from the side in microns.
