They are otherwise typical, and show the usual wide range of variation charac- teristic of the species. Dr. Skinner has stated that there are no secondary sexual characters in neurona but we note one difference that seems fairly constant throughout our series of 70 specimens. In the males, an orange suffusion extends along the costal margin of primaries (upper surface) which is widest at the base and tapers toward apex. Only two females in our series show any suggestion of this. The variation in neurona consists principally in the degree and extent of the orange "; This ranges from clearly marked individuals in which every nervule is distinctly lined with orange, to specimens in which there is no orange whatsoever on the nerves and which are practically indistinguishable from acmon females. The accompanying plate illustrates several of the points of dif- ferentiation which we have here analyzed. In addition to showing Plebeius emigdionis, neurona, chlorina and the new variety carolyna, there is shown a cut of the male of Philotes speciosa.
