No other insects could have hidden in the vials un- 
detected because all coccoons in the vials were dissected with 
forceps at the time of examination. 
The two virgin $ $ of vial No. 1 were placed in a 
separate vial and when the female of vial No. 2 emerged, 
she was placed with them. 
Of the four females in vial No. 3, three were placed in 
a single vial and the fourth in a separate vial. 
The female of vial No. 4 was also given a separate vial. 
Mr. Brid well’s objection might be thought to apply to 
the two virgin females removed from vial No. 1, had I not 
examined their cocoons for holes when I removed the wing- 
less $ and the wingless $ . 
But supposing Mr. Bridwell’s assumption to be correct 
in the case of vial No. 1, and, that sperm could have been 
transmitted through holes in their cocoons too small to be 
detected with a hand lens, this would throw out only the 
data obtained from the virgin females of vials Nos. 1 and 
2, the offspring of which (born Oct. 31) consisted of 14 
wingless females. 
Even then, we would be unable to account for the 19 
9 2 from the virgin females born in vials Nos. 3 and 4 in 
which vials no males occurred.
