_D_e_s_c_r_i_p_t_i_o_n:

     This data set consider physical information of 74 male
     flea-beetles reported by Lubischew  (1962). Information of three
     species (Ch. concinna, Ch. heptapotamica, and Ch. heikertingeri) 
     is considered and 6 measurements on each flea-beetles.

_F_o_r_m_a_t:

     A data frame with 74 observations on the following 7 variables.

     '_f_j_f_t' a numeric vector giving the width of the first joint of 
          the first tarsus in microns (the sum of measurements  for
          both tarsi)

     '_s_j_f_t' a numeric vector giving the width of the second joint of 
          the first tarsus in microns (the sum of measurements  for
          both tarsi)

     '_m_w_h_b_e_e' a numeric vector giving the maximal width of the head 
          between the external edges of the eyes in 0.01 mm

     '_m_w_a_f_p' a numeric vector giving the maximal width of the aedeagus 
          in the fore-part in microns

     '_f_a_a' a numeric vector giving the front angle of the aedeagus  (1
          unit = 7.5 degrees)

     '_a_w_f_s' a numeric vector giving the aedeagus width from the side 
          in microns

     '_s_p_e_c_i_e_s' a numeric vector giving the species: 1=Ch. concinna, 2=
          Ch. heptapotamica, and 3=Ch. heikertingeri
