Tetropium gabrielt in which the right antenna consisted of only 
eight joints and bore a basal branch of three joints; a specimen

the antenne bearing a short three-jointed branch arising from the

country. VI. Experiments in breeding. VII. Variation. (1) General 
characteristics. (2) Lines of variation. (3) Sexual Variation. (4) List 
of aberrations (striking aberrations are very rare). (5) Geographical 
races. VIII. Suggested questions for further investigation —Mr. 
Gibbs discussed some of the same points, especially referring to his
