genetic terms the combination bilateral and mosaic pattern. Perhaps information on the origin and order of development of the various parts of the insect are graphically demonstrated.
I am more than casually impressed that the year 1962 also yielded bilateral gynandromorphs of Eacles imperialis Drury and Callosamia promethea Drury. The former was captured in the presence of Joseph Muller at Pottersville, New Jersey, on 20 July 1962 and is in his collection. The latter was found by a young lad, Richard Orelup, at Crown Point, Indiana, among several moths emerging from cocoons.
Since this is such a rarely encountered phenomenon in the Lepidoptera, especially remarkable for as extensively collected a group as the Saturniidae, it makes one wonder if the finding of three gynanders in one year is within the limits of expectancy for the conditions under which we have heretofore been collecting, or whether some fundamental environmental change is now actually taking place. It is hoped that anyone who has had experience with lepidopterous gynandromorphs of this nature, particularly with finds of recent date, will communicate the information to me, or report it in this Journal.
THE FIRST RECORD OF EUREMA CHAMBERLAIN1 (PIERIDAE) IN THE UNITED STATES
During the latter part of March and the first of April 1963, Dr. Howard Weems and I were on a collecting trip through central and southern Florida. On 30 March, we were collecting at Ross and Castillo Hammock, Dade Co., Florida, where I was so fortunate as to take a specimen of Eurema chamberlaini Butler. At the time, I was collecting Eurema lisa for a type locality series and did not realize I taken a rare specimen until I mounted the material later in the fall.
I would like to thank Frank W. Mead for his assistance and Dr. A. B. Klots who made the determination and stated that it is the first known United States record for this species.
The specimen is deposited in the Florida State Collection of Arthro­pods, located in the Division of Plant Industry, Florida Department of Agriculture, Gainesville, Florida.
