Besides the normal phase of inaequalis there was a paler red 
form with four round black dots arranged in an oblique-sided 
quadrangle on each elytron, a common dot on the elytra near 
their apex, and usually two similar dots near the middle of 
the pronotum. This form, represented in Figure 2, may be 
called the nine-spotted phase from the nine dots on the elytra. 
The dots vary a little in size, but there has been observed no 
tendency whatever for this form to intergrade with the normal 
phase. 
The third form was solidly black with only the anterior 
corners of the pronotum red, and I shall refer to it as the 
black phase (Fig. 3). It was the rarest from at first, although 
later obtained in number. It apparently was not included 
among the original lot of beetles which came from the Herbert 
River, Queensland, but two specimens were reared in the first 
generation from the stock supply of beetles, and thus of 
unknown parentage. 
My first experiments were directed towards finding out the 
behavior of the nine-spotted and normal phases towards each 
other in heredity. Consequently, on August 26, three nine- 
spotted females were isolated in vials, and a record kept sep-
