IS. A Note on Ovipositing Females of Colias philodice (Lepid.). 



At Blacksburg, Virginia, June 30, K)03, in a clover field, I 

 watched females of this common butterfly for two hours in 

 the morning — the sun shining brightly — and they seemed to 

 be flitting about in a frivolous manner, alighting here and 

 there and placing an egg by curving the abdomen up to the 

 spot intended for it. Seemingly, they thus continue, hour after 

 hour, moving ceaselessly and apparently at random, but never 

 failing to pause here and there to leave an egg. The latter 

 becomes pinkish after about twenty-four hours. 



19. On Hyphantria cunea Drury (Lepid.). 



There was found on Alay 10, 1902, at Blacksburg, Virginia, 

 a female of this species laying eggs upon an apple leaf. On 

 the following dav. the moth having been confined, oviposition 

 was completed, the female then dying. The eggs are depos- 

 ited in an irregular circular mass on the under surface of the 

 leaf, in a single compact layer, and covered with a loose net- 

 work of gray hairs from the abdomen of the parent moth. 

 They are pale green, nearly the color of the surface upon 

 which they are deposited, circular from above. Their surface is 

 simple, but when seen under a microscope with tubercular pro- 

 jections. By Tune 4, the larvae from these eggs had grown 

 to nearly a half inch and were then colored like the older 

 larvae. 



On June 20 it was noticed that in their nests the larvae in 

 the field were only about a third grown. The second genera- 

 tion of larvae was a quarter of an inch long by the first of 

 September, 1902. 



20. Variation in Hibernating Adults of Megilla maculata DeGeer 



(Coleop.). 



A large mass of this beetle was found hibernating under a 



large chip of wood near a stump in a ploughed field near 



Paris, Texas, February 25, 1904. In several individuals a 



large mesial portion of the elytra was olive green, changing 



gradually to the usual pink from its edges. Also many speci-
