I repeat here, for the benefit of American readers, the descriptions of two abberations, given by me originally in the pages of the Insekten Börse, 1920.

Samia Californica, ab. parvimacula—The male specimen is of a lighter red than usual, and the lunate discal spots are so reduced on all four wings as to appear half the usual size. They are, in fact, narrow, and only about 5 mm. in length, squarish in form. The antennæ are greatly reduced, the usual length being about 20 mm., while here they are only about 14 to 15 mm., and the pectinations appear to be proportionately reduced. The expanse is normal, about 95 mm., but at first sight the specimen suggests a different species.
