These data may be studied in the order given. 
Eeo.—For the first two lots the temperature is the same with only a 
slight difference in humidity, but during the period of the first lot rain 
fell for a part of the time on 3 successive days; during the second 
none fell at all. Under these conditions the duration of the first lot 
was 1} days longer. The period covered by the next two lots of Au- 
gust 15 and August 16, furnish about the same conditions with the same 
results. The next three lots were deposited much later in the season, 
had lower temperature and excessive rains, 6.37 inches having fallen 
from September 22 to 25 inclusive. The duration of the egg state as a 
result was much prolonged. There is no check on this lot, however, 
since no eggs under direct observation were hatched during that sea- 
son with the same low temperature but without the excessive rains. 
From general observations, however, there is no question but that low 
temperatures also prolong the duration of the egg state, the same as 
the rains seem to have done in each of the two first lots mentioned. 
Larva.—tThe first two larve were reared under almost exactly similar 
conditions and, as will be seen, matured almost at the same time. As 
compared with those that follow the duration is of interest, as there 
was but little rain and a high temperature. The next two were worms 
hatched from the same lot of eggs, and, as is seen from the table, were 
reared under exactly similar conditions. Despite this, the difference in 
time of maturing is 5 days. This can only be accounted for by the pe- 
culiarities of thespecies,such as have been previously discussed. The 
difference, as compared with the two preceding, was principally due to 
the much lower temperature. If, with the abundant rain during that
