We found the number of wasps far greater than we had sup¬ 
posed it to be when we began our investigations a month earlier. 
Nest No. 1. (V. germanica.) 
Opened Aug. 25th, contained 2,269 °, 297 <1,19 =2,573. 
We found a great many eggs and larvae, especially in the 
queen cells, but unfortunately did not count them. 
Nest No. 3. (V. germanica.) 
Opened Aug. 30th, contained 1,506 °, 585 d , 54 9 =2,145. 
We found eggs and larvae as in the first nest. 
Nest No. 4. (V. germanica.) 
Opened Sept. 17th, contained 1,438 °, 695 d , 683 9=2,816. 
It also contained 50 eggs; 512 9 larvae and pupae; and 
1,283 0 and d larvae and pupae, making the total number of 
wasps, in various stages, 4,661. 
Nest No. 5. (V. germanica.) 
Opened Oct. 8th, was deserted. We counted 1,097 9 cells. 
Nest No, 6. (V. germanica.) 
Opened Oct. 8th, was also deserted. We found 97 9 unde¬ 
veloped, and 536 9 cells, giving a total of 633 9 
Prof. Wyman, in the paper referred to p. 414, speaks of open¬ 
ing a nest of either V. germanica or V. vidua on October 12 in 
Massachusetts, where the autumn is a little later than with us in 
Wisconsin. He found the adult population of the nest nearly as 
follows: 9 24, d 236, ° 388, = 648. He is not explicit as to 
the number of undeveloped queens, but since he states that the 
nest was four stories high, nearly spherical , and five inches in 
diameter, and that the fourth or lower comb was of queen cells, 
and that “ the larger portion of the cells for the females had been 
used and others were stfl.1 occupied by pupae, and the entrances 
were still sealed up,’ 5 we are safe in supposing that there must 
have been, taking mature and immature together, at least 200 
queens. He evidently did not count the cells since he says 
‘"there were also between 100 and 200 larvae.” We counted the 
cells in a 9 comb from a nest of the large hornet V. maculata. 
The comb was five inches in diameter and contained 332 cells, 
■and as the queen cells of the smaller hornet measure one-third
