investigate this and the further question of first-leg form consid- 

 ered below eggs were collected during the summer and brought 

 to New York where the newly hatched individuals might be 

 observed. 



These eggs were kept in small loosely stoppered bottles in the 

 laboratory at ordinary room temperature. They began hatching 

 about the first of December and during January a large number 

 of the insects came out. 



BEHAVIOR OF NEWLY HATCHED APLOPI. 



The reactions of the small insect on the day it emerges from 

 the egg are almost identical with those of the fully mature eight- 

 inch females which I studied at the Tortugas. The young 

 Aplopi are a light chocolate-brown in color with yellowish bands 

 about the legs and the sexes are similar. The adult males, 

 however, become greenish in color while the female retains her 

 original brown. The adults also have rudimentary wings which 

 are capable of being raised when the insect is excited, but the 

 young are wingless. Their reactions will be referred to briefly 

 at this time as they are given in some detail in my former paper. 



The insects when at rest among the twigs assume an attitude 

 which in consequence of their stick-like shape makes them most 

 difficult to detect. The first pair of legs are stretched directly 

 forward enclosing the head between thin curved portions of the 

 femora which fit perfectly against it. The antennae are brought

 first pair of legs are stretched forward in the typical resting attitude. The femur fits 

 perfectly about the ventro-lateral region of the head and leaves the eyes uncovered.

 forward and enclosed between the first pair of legs.
