Robert E. Birdsong published some notes on Tropaca luna in the November 1932 issue of this magazine, which were of especial interest to us as we have been working along the same lines.

In addition to the variations in ova-coloration which were mentioned the article, we have obtained ova which ranged in color from sky-blue to apple-green. In one of the few cases in which we obtained pure white ova, they turned green after a few days and never hatched. We have not noticed black micropyles.
