August 31, all the breed- ing forms were of this type, and not until Septem- ber 12 was the occurrence of another series of larger forms noted. These large forms increased in number until, on the twenty-fourth, none others occurred. The specimens of this seventh series of parthe- nogenetic females are about seven-hundredths of an inch in length, and appi'oach in form the stem- mothers. The honey tubes are long and slender, equal to three body segments, and the an- tennje equal half tne entire length of the „, . 1 •* • *v, ijj^^v^tFig. 31—, agamic, . insect.

September 27 it w^as seen that a new series of slender, oval examples had made its appearance, and on October 1 it was possible to distinguish the male and female larvae. October 4 true males and females were found, and from this time on they became increasingly abundant, while the partheno- gentic females as gradually disappeared, isolated specimens lingering to November 1. A male appears like a larva in the second stage as to size: but the legs are long and slender, the tibiae are clothed with hair, and the form of the anal segment is altogether different from any type of any previous series. The antenna? are almost as long as the entire insect, and sensory pits occur on all save the two small segments at the base. The third joint is longest, and has nine to ten pits, irregularly placed on all sides. The fourth seg- ment is two-thirds the length of the
