pink female which was crossed with a normal green male. On 

 September n, and again on the i8th, I saw on each occasion 

 that she carried a spermatophore attached to the end of her ab- 

 domen, showing that union of the sexes had occurred, and it is 

 reasonable to suppose her eggs had been fertilized. I saw the 

 green female on the ground several times, her body at this 

 time being fully distended with eggs, and while I did not see 

 her oviposit, she doubtless laid most of her eggs. Proof of 

 this fact was shown by a post-mortem examination following 

 her death, November i, 1915. I found at this time on dissec- 

 tion only eight eggs in her body, and as the usual complement 

 is about thirty-two, she had doubtless laid in the ground the 

 larger portion. I supplemented these by placing in the ground 

 the eight eggs I recovered from her body. 



HABITS O<F PINK KATY-DIDS: THEIR EGGS AND How THEY 



ARE LAID. 



In reviewing the habits of pink katy-dids, I find that they do 

 not differ from those of the ordinary green form. However, 

 in the course of my investigation, I have observed some points 

 relative to the behavior of Amblycorypha oblonglfolia which 

 are of general interest, and seem worthy of record. These in- 

 sects enjoy the sunshine, seeking sunny exposures when possi- 

 ble ; are slow and cautious in their movements, and they feed 

 on a variety of leaves of plants, as well as the petals and pollen 

 of flowers. They are especially fond of the leaves of some 

 mints, and the flowers of some of the goldenrods. The adults 

 of the ordinary green form more often frequent the edges of 

 woods and thickets in damp situations. They live above ground 

 among the leaves in preference to the ground, except when 

 laying their eggs. The young emerge during late May or 

 early June, and mature about the first week in August. From 

 the time immediately after they hatch, throughout their lives 

 they remain the same color, showing that this is a character 

 which is hereditary, though as I have noted, the color may be 

 temporarily intensified or may become paler through the action 

 of humidity and temperature. These color fluctuations were 

 determined in my pink katy-dids by comparison with a scale
