until a few hours before hatching when it is defined by lines 

 of yellow, punctiform spots. The newly hatched nymphs are 

 red, the abdomen green; the colors of the first stadium are 

 present after about a half-hour. 



A female observed depositing eggs on June 20 (in rearing 

 jar) laid one about every minute and a quarter; during the pro- 

 cess the tip of the abdomen was rubbed up and down the sur- 

 face of the leaf for short distances. When the egg was passed 

 the abdomen was lifted, whereupon a knotlike swelling could 

 be seen passing slowly down and out of the oviduct. This was 

 the egg. It was extruded base down and placed on the spot 

 where the abdomen's tip had been rubbing. 



In a garden, egg masses of this species were found on the 

 foliage of cotton and watermelon. 



11. Notes on Hadronotus carinatifrons Ashmead (Hymen.). 



Females of this egg parasite were observed in the field at 

 Paris, Texas, June 11, 1904, depositing eggs into a mass of the 

 eggs of Anasa tristis. The mass of host eggs contained thirty- 

 four individuals; it was kept and the resulting adults of the 

 parasite emerged during the morning of June 28 ; the non- 

 parasitized host eggs hatched between June 20 and June 23. 

 The Hadronotus continued to emerge until July 3. 



Adults kept in confinement with fresh lots of host eggs de- 

 posited into them, died usually after from twenty-four to thir- 

 ty-six hours. The ovipositing female straddles over the host 

 egg when depositing into it, the legs usually resting on adjoin- 

 ing hosts ; the body is very still, humped, the head and an- 

 tennae held down, the latter quiet and held against the face or 

 else hanging inert ; the posterior legs are extended backward 

 and fixed to the sides of the attacked egg as if pulling, while 

 the whole body at times pulsates almost imperceptibly back 

 and forward. A single egg is deposited into each host and this 

 usually at one end of it, low down, so that the female's body 

 during oviposition is usually inclined upward. After deposi- 

 tion the female usually crawls off a short distance and then 

 returns to the mass of host eggs to recommence.
