lieve one is the usual number. A number of galls collected 

 from Solidago in the winter of 1903 yielded the adult flies on 

 May 13 and 15. A eurytomid also appeared. The fly was 

 identified by Coquillett. The exit-hole is large and round. 



8. Number of Chalcidoid Parasites from Arctiiad Pupae (Hym.). 

 Three arctiiad pupae were found at Blacksburg, Virginia, June 25, 

 1902, under fence rails lying upon the ground. All were parasitized. 

 From one, a hundred and fifteen parasites emerged, while from a sec- 

 ond only forty-four. The other was lost. Neither host or parasite 

 is known. 



9. The Fowlbug, Cimex columbarius Jenyns (Hemip.). 



An adult of this relative of the common bedbug captured 

 in a henhouse at Anacostia, District of Columbia, September 

 24, 1905, and placed within an ordinary physician's pillbox, 

 retained its normal color until death occurred on March 31, 

 1906. It was not fed and lived in captivity a hundred and 

 eighty-eight days without nourishment. It was recently fed 

 when captured and of the female sex. Another female was 

 captured at the same time, and similarly kept ; it died about 

 the middle of December following. Both were alone. The 

 second female produced seven young, which hatched by Oc- 

 tober II. A third adult died a few days after capture, though 

 it had been fed once upon recently born mice (Mus). A 

 nymph (fifth stage) captured with the others molted to adult 

 on September 29 and died on October 7, 1905 ; it was not fed. 



Three nymphs of the first stage were fed on human blood 

 by giving them access to a lower portion of the fore-arm,
