two held together by the claspers only; the act occupies an 

 hour or more. The following day (July 22) eggs were found; 

 at first these are pinkish, changing as the embryo reaches 

 perfection to purple, or rarely, a bright orange or red ; just 

 before hatching, they are lavender in color. The mass noted 

 above hatched early in the morning of August 5, or after 

 about fourteen days plus. Ichneumonoid parasites of the 

 larva were common. 



Hatching in this species occurs by means of eating a round- 

 ed piece out of the top of the tgg. One female deposited 

 two masses of eggs totaling a hundred and thirteen. On July 

 14, 1902, a colony was taken from cottonwood or Carolina 

 poplar. 



4, The Occurrence of Acronycta hamamelis in Virginia (Lep.). 



Larvae of the species were captured from oak, August 26 and Sep- 

 tember 2, 1902. A larva captured on the first date made a cocoon 

 early in September. 



5. The Number of Pteromalids From a Single Chrysalis (Hym.). 



At Blacksburg, Virginia, May 21, 1902, two parasitized chrysalids of 

 Basilarchia archippus Cramer were given to me by Professor William 

 B. Alwood. The pteromalids emerged on May 28. From one chry- 

 salid, there were obtained three hundred and seventy-five. The species 

 was probably Pteromalus graptae Howard, though it is not sure. 



6. Hidden Aphid Eggs (Hemip.). 



Once when T was examining an eggmass of Malacosoma 

 americana, the well-known black eggs of a species of Aphidae 

 were found hidden in the spaces between the eggs of the bot- 

 tom of the mass, or that part of the mass which was next 

 to the twig. Subsequently numerous cases of this kind were 

 observed. The tree was apple. Blacksburg. \'irginia. Febru- 

 ary, 1903. Since the overwintering eggs of the aphids are 

 not deposited until late in the autumn and the overwintering 

 eggs of the moths, months previously, early in summer, it 

 is a mystery how the aphid eggs were thus deposited. 



7. Trypeta polita Loew (Dip.). 



The small, roundish galls of this dipteron are found dur- 

 ing the winter in \'irginia on composites. The interior of the 

 gall is pithy and may contain two larval cells, though I be-
