The circles connected by a zigzag line give the means of the arrays of propodite length for given types of cephalothorax length. The straight line is the calculated line of regression. The characteristic equations connecting the characters are as follows, where PI denotes probable mean length in millimeters of the propodite of leg i for a given cephalothorax length C; and Mm denotes probable mean length .11 millimeters of the meripodite of leg in for a given length, MI, of the meripodite of leg I : = 1.2214C -11.057 = .7720Jfi+ 1.042 (i)
